FSP Epsilon 80PLUS 450W / Chassis, PSU and cooling

3DNews Cases, PSUs and Cooling Power Supplies The most interesting news Today in our laboratory — 450 W power supply from the company FSP Group from the new Epsilon 80PLUS family. We get acquainted with the characteristics, prepare, study the model in practice The pages of our site have repeatedly published product reviews of the Taiwanese company FSP Group — one of the leaders in the power supply industry. It would seem that quite recently, the FSP trademark, under which power supplies in OEM / ODM design have been supplied for more than ten years for large-scale wholesale customers, was known mainly to specialists. However, quite a bit of time has passed, and the FSP brand is «on everyone’s lips», especially after the opening of the Russian representative office of the company. Today we will get acquainted with the FSP power supply of a relatively new series — Epsilon 80 PLUS , and above all a few general characteristics of the entire family. Our readers are certainly familiar with the FSP Epsilon family of powerful power supplies. The appearance in the name of the series of additional markings 80 PLUS means compliance with the requirements of the standard of the same name. Let me remind you that the 80 PLUS standard implies the operation of a certified power supply with an efficiency of at least 80% at a load in the range of 20% — 100% of the declared nominal value. Similar to the Epsilon family, the Epsilon 80 PLUS power supplies come in retail packaging (although I won’t bet that the exact same circuitry isn’t used in OEM versions or retail versions, but already under the brand name of a contract customer). «Color differentiation of pants» in the Epsilon 80 PLUS family is implemented by changing the color of the box (without changing the plot), while maintaining the «visiting card» of retail PSUs produced by FSP — the dark blue color of the cases of the power supplies themselves. As you can see, the Epsilon 80 PLUS family, represented by the 450W, 500W, 600W, and 700W model range, is a far cry from the «regular» Epsilon series, represented by the 600W, 700W, 800W, 900 W and even 1010 W. Today in our laboratory for testing is the youngest model of the family, Epsilon 80PLUS 450W . The table below shows the detailed characteristics of the model, taken from the manufacturer’s website.

At various ends of the box, in various ways — with pictograms and lists, the key characteristics and functionality of the device are indicated. nine0007 Inside the package — a power supply, a power cable, fasteners, a couple of branded nameplates with FSP logos, a user manual, and an additional Velcro for tightening cables when mounted inside a PC case. The FSP Epsilon 80PLUS 450W power supply is based on a rugged chassis; the walls of the hull are quite thick, the dark blue paint that is used to paint the hull is very stable. nine0007 The power supply has a sufficient set of power cables, including the main 20 + 4-pin, two 4-pin (4 + 4) + 12V power connectors; one floppy drive power cable; five S-ATA power connectors; six 4-pin Molex connectors and two PCI-Express power connectors for powering two video cards in an SLI/CrossFire system. The cables are laid in a shielding «mesh»; good; long enough. The cooling system of the FSP Epsilon 80PLUS 450W power supply includes a 120 mm fan manufactured by Yate Loon Electronics (12V DC, 0.3A). nine0007 Let’s take a look under the lid. Pretty neat installation; The radiators of the heat dissipation system cannot be said to be so massive, but this is probably enough for a 450 W model. Before proceeding with testing, I note that the Epsilon 80PLUS 450W power supply has a number of typical overload protections. This is protection against a significant overvoltage: for the +3.3 V channel, the response threshold is set to 3.76-4.8 V; for the +5 V channel, the threshold is 5.6-7.0 V; for 12 V channels — about 13.5-16.5 V. This is overload protection with the following limits: 60 A for +3.3 V channel; 48 A for +5 V channel; 30 A for each +12 V channel. In addition, short circuit protection is implemented — when the load resistance is less than 0.1 Ohm. nine0007 How and what we tested Since the methodology for testing power supplies currently used in the 3DNews laboratory has not undergone any changes lately, I suggest that our readers familiarize themselves with its details, for example, in the previous article; there is not only a description of the stand, but also a transcript of the results of automatic measurement of cross-load characteristics. Here I will limit myself to reminding you that our stand allows you to provide a rated load of up to 600 W, while there are only two channels for a 12V voltage load. Our PSU testing methodology and test bench equipment are currently in the process of further improvement. nine0007 FSP Epsilon 80PLUS 450W test results Recently, manufacturers of power supplies have a new fashion — to put down in the characteristics of the PSU on the cases such currents through the channels, which, when summed, make you simply grab your head. Here, for example, is how the FSP Epsilon 80PLUS 450W power supply is marked. If it were not for the line below such a parameter as the maximum combined load power in the sum of several channels, one would think that we have a kilowatt monster! Judge for yourself: only the sum of the key channels — 36A ​​x 3.3V + 30A x 5V + 4 x 18A x 12V, gives us a total of 1132.8 W! No, why, no one argues that a 5-volt channel is capable of delivering 30A, or, say, two 12 V channels can withstand 18A each. But, excuse me, what is the point of indicating, for example, the total power limit of 3.3V and 5V channels of 155 W? From a formal point of view, there is nothing to «undermine», but the total «kilowatt power», which exceeds the typical characteristics of 700-watt models, frankly, discourages. Here, perhaps, is the only moment that somewhat «jarred» me in the process of testing this model. However, if you carefully open the instructions that came with the FSP Epsilon 80PLUS 450W power supply, everything falls into place. Just there, in addition to the maximum values ​​of the load on the channel, both the nominal parameters and the minimum are given. With nominal parameters, all this looks much more reliable. nine0007 However, in the mode of automatic measurement of cross-load characteristics, the FSP Epsilon 80PLUS 450W power supply was tested outside only in the nominal mode, with settings in accordance with the «nominal» passport data (the total load of 12V channels is not more than 435 W, the total load is 3.3V and 5V channels — 155 W), but also with slightly increased ones, when the total load slightly exceeded 500 W. Do not consider this as «revenge» on the characteristics indicated on the case, but I really wanted to «drive» this model, fortunately, our 600 W stand allows it. As you can clearly see in the screenshots below, everything went without incident. A certain «drawdown» of 5V and 12V channels at the peak values ​​of the total load (upper left corner) only emphasizes that the «working» load zones correspond to those declared for the FSP Epsilon 80PLUS 450W and do not start from «zero» (the declared minimum is 0. 5A for the channel 5V;0.9A for channel 12V3 and 0.1 A for channel 12V4). The static load was also measured in various modes, including, in the screenshot below, you can evaluate how the FSP Epsilon 80PLUS 450W «behaves» with a total load of more than 500 W. As you can see, with a balanced load, the voltages of all channels are in the normal «color zone». In order to see the screenshot in full resolution, you must click on the image below. nine0007 A few words about the noise characteristics of the FSP Epsilon 80PLUS 450W. In full accordance with the declared characteristics, there is a so-called «Silent Guard» mode. That is, at a load of less than 20% of the nominal, the fan simply does not spin, the cooling system is quite satisfied with the heat sink provided by the radiators. As the load increases, the fan speeds up accordingly, but even when overloaded above the PSU rating, it is quite quiet. nine0007 Total Solidly executed, beautifully packaged, quiet and pretty, the FSP Epsilon 80PLUS 450W power supply withstood all the tests in our test lab. To my regret, the search for approximate prices for the FSP Epsilon 80PLUS 450W power supply did not bring any result — neither in google nor in market.yandex there is nothing about such a model yet — which is not surprising, since the model is really new. So the verdict will be this: the FSP Epsilon 80PLUS 450W power supply is good in itself, without any reservations, but if the manufacturer takes care of the correct price positioning of this new product, sales success is guaranteed. nine0007 — Discuss the material in the conference If you notice an error, select it with the mouse and press CTRL+ENTER.

modern ultra-quiet «gold» / Cases, PSU, UPS, case cooling, surge protectors / iXBT Live

Greetings to everyone who looked at the light. The review will focus on, as you probably already guessed, a high-quality premium power supply Be quiet! Straight Power 11 with a rated power of 650W. This model is certified 80 Plus Gold, has an ultra-quiet fluid dynamic bearing cooling system, long tails and full modularity. The review will include a description, disassembly and testing, so if you are interested, you are welcome…

You can buy it HERE

— Total power on the +12V line — 649. 2W
— Channel stabilization — separate

Straight Straight Contents:

• PSU Power 11650W
• — Set of cables
• — Mains cable with euro plug
• — 4 fixing screws
• — 3 cable ties (organizer)
• — Manual

Be quiet! Straight Power 11 650W comes in a traditional dark box with brief characteristics:

The manufacturer focuses on the PSU belonging to the premium segment. And for good reason, because this model corresponds to the «gold» standard 80 Plus Gold, has a high-quality element base, an ultra-quiet cooling system and full modularity. nine0007

On the reverse side of the box are the main features of the model, overall dimensions, cable length and number of connectors (connectors): :

For connection, a power cable with an euro plug is designed for 250V / 16A:

A nice bonus is the instruction with explanatory pictures in several languages, including Russian. nine0007

In total, the equipment is very good. Mounting screws and ties (organizers) for cables are present. The box is quite dense and must withstand all the «bullying» of the Russian Post when delivered from online stores.

Appearance:

Be quiet! Straight Power 11 650W is made in the traditional simple style without any design frills:

Like most Be quiet! the case is painted with dark powder paint and stands out, perhaps, with a stamped company logo and an unusual protective grille (grill) of round section:

Unlike molded grills, the round shape of the grille profile is more streamlined and traps air less, which has a positive effect on noise level and cooling efficiency.

The appearance of the power supply from all sides:

I would like to recall that the monitored power supply is the third representative of the Straight Power 11 series in terms of rated power and is certified according to the 80 Plus Gold standard, so you can count on an electronics efficiency of no more than 93%. In total, this series has six models with power from 450W to 1000W, and we can say that the reviewed PSU is the «golden mean».

The main load characteristics and the model name are present on the side of the case:

According to the table, the PSU can deliver almost full power through the most popular +12V (649.2W) bus, which is relevant for modern systems. It is worth noting that the +12V bus is divided into four independent lines for improved signal stability: 12V1 (ATX and peripheral power), 12V2 (processor power), 12V3 and 12V4 (video card power). Connecting a powerful consumer to one of the lines does not affect the others in any way. nine0007

On low-voltage buses +3. 3V and +5V, the power is limited to 140W and is rather redundant for modern systems. It will be relevant, perhaps, for older platforms based on AMD processors.

Complete modularity of the cable system is a definite plus, allowing you to connect only the necessary wires:

Modular power wires:

Be quiet! Straight Power 11 650W has a complete modular cabling system, which means that absolutely all cables are removable and only the necessary ones can be connected. The advantages of this solution are obvious:

• — firstly, you can connect only the necessary wires as needed
• — secondly, fewer wires inside the system unit improves air circulation, providing more favorable temperature conditions
• — thirdly, it makes it easier to remove the PSU for cleaning or diagnostics, because it is enough just to snap off a few connectors and, having unscrewed four screws, remove the power supply. No need to remove neatly stowed motherboard and graphics card power cables
• — fourthly, in special cases, you can replace the wires with better and longer ones, which is especially important for server systems or just tall cases. Full modularity is also useful in the case of modding with the connection of RGB-backlight
• — fifthly, in case of wire breakage and other curiosities, it is enough to simply disconnect and replace it with a similar one

connectors:

According to the table, the length of the wires is enough for laying even in a spacious case, and the number of connectors (sockets) for a modern system unit is even redundant.

For better organization of wires inside the system unit and air circulation, all cables are neatly wrapped in black braid:

The set of cables is as follows: 12V 4+4pin) — 1 cable, 1 connector

The quality of the wires is very good: they are moderately soft, certified by the American office Underwriters Laboratories Inc. and passed some high temperature resistance tests (VW-1). The processor (CPU) power wires, as it should be in high-quality top-level PSUs, have an impressive length of 700mm and a cross section of 16AWG, which simply cannot but rejoice:

For those who are not in the know, AWG is an American wire gauge and the lower the number, the larger the cross section. Everything is similar to the caliber of a firearm. In turn, the larger the cross section, the lower the total resistance of the wire and, therefore, less heating and voltage loss, which is especially important at high loads.

Video card power wires (PCI-E) are 600mm long and 16AWG: ) are additionally duplicated by a second wire of the same cross section:

The wires for connecting the peripherals are 550mm long and have a cross section of 18AWG:

power consumption on these lines is low.

Power supply disassembly:

Disassemble the Be quiet! Straight Power 11 650W without loss of warranty is not possible due to the presence of a warranty sticker. The disassembly itself is not particularly difficult, because the case is fastened with only four screws:

With the cover removed, the PSU looks like this:

The connector for connecting the fan is filled with compound, and the electronics on the main and vertical boards are additionally insulated from the case using an insulating gasket:

Board appearance:

Power 11 circuitry is the same and based on LLC, SR and DC-DC resonant conversion topology, therefore it provides high stability and accuracy of voltage regulation. The blocks differ only in the set of components to provide the declared power. nine0007

The primary power circuit is a complete EMI filter designed to filter out interference. Part of the filter is soldered on a separate board near the network block, part on the main board:

All the necessary components are present, and the chokes are additionally wrapped in a layer of insulation. The GBU1506L 600V / 15A diode bridge is installed on a radiator, although it operates in a sparing mode:

Next are the elements of an active power corrector, which usually consists of a control driver, power mosfets, a choke, a Schottky diode and a capacitor:

On the right is a board with a control driver (the photo was smeared, the marking remained unreadable), which controls the Infineon IPW60R190P6 (650V / 57A) mosfets in conjunction with a 600V / 9A Schottky diode C3D06060A installed on a radiator:

They are helped by a massive ferrite choke ring and an electrolytic capacitor of the Nichicon series with a declared temperature of 105°C. According to some information, a 420V/470µF capacitor is installed (up to 105°).

Next are the power keys in the amount of two pieces (most likely K16A60W), fixed to the heatsink through thermal paste:

Controls the operation of the CM6901T2X controller, soldered on a separate board:

Composite power lines (5V and 3.3V) are implemented on DC/DC converters APW7159C on a separate board: circuits and LC filter:

The tracks on the board with modular connectors are reinforced with solder to reduce losses and there are additional solid capacitors:

In total, the installation is neat, the flux is completely washed away, there are no specially trained «jumpers». As stated by the manufacturer, there are no wired connections inside the PSU, which helps to reduce losses and improve cooling. nine0007

Cooling system:

The cooling system used is a 135mm Silent Wings 3 fan with a hydrodynamic bearing connected to the board via a connector:

inaudible at work. In addition, automatic speed control is used here depending on the temperature inside the unit and at loads up to 50% of the rated power, the fan barely spins and you can see its blades. The maximum rotation speed is no more than 1500 rpm. nine0007

The method of attaching the fan to the PSU case is also important. Here, the fans are mounted using special brackets:

I would like to see some silicone dampers, but I repeat once again, at loads up to 350W, the fan barely rotates and makes almost no noise. According to the specifications, the noise level does not exceed 17.5dB:

Testing:

The following types of protection are declared by the manufacturer:

• — UVP (undervoltage protection) — if the voltage drops below a certain tolerance value in single lines, the power supply will automatically turn off
• — OVP (overvoltage protection) — if voltages exceed a certain tolerance value in single lines, the power supply will automatically turn off
• — SCP (Short Circuit Protection) — in the event of a short circuit, this function prevents damage to the main components of the power supply
• — OPP (Overload Protection) — if the system is large and requires more power from the power supply than it can handle, this protection function is activated
• — OCP (overcurrent protection) — if the load on one line is higher than specified, the power supply automatically turns off

A short circuit was simulated on the test bench on the main lines — the PSU immediately turned off. Reactivation is only possible by disconnecting and reconnecting the ATX connector (reapplying the Power On signal).

As usual, I did not reinvent the wheel and used 55-60W incandescent lamps as a load, plus a primitive electronic load. Since the Be quiet! Straight Power 11 650W has 4 separate lines with its own protection, so I had to slightly modify the stand and add a few devices. So that there are no holivars in terms of accuracy, I will give a small comparison of devices. Comparison with a reference voltage source (SV) based on the most accurate AD584LH chip in the series:

Since the current in series connection of the circuit is the same throughout the entire section, we compare the readings of ammeters:

The accuracy corresponds and is within the error.

Now directly testing. First, let’s look at the consumption of the PSU without load and the level of output voltages:

As you can see, in idle mode, the consumption of the PSU is slightly less than 7W (0. 7W is consumed by the wattmeter itself), the output is 5.06V and 12.38V. It should be noted that the voltage on the 12V bus is somewhat overestimated, but is within the standard. Let me remind you that the ATX standard allows deviations within 5%, which means that the voltage can vary from 11.4V to 12.6V. I’ll add on my own that it’s often better to “a little more”, because with a good load, there is some voltage drop in the wires. nine0007

Next, a few words about the stand. As I mentioned earlier, the PSU has 4 independent lines, so I decided to load 3 buses — 12V2 (CPU), 12V3 (GPU) and 12V4 (GPU), and remove the voltage at the output of the 12V1 bus (from the block). This economy looks like this:

As practice has shown, the voltage on each bus is practically independent of the load on the others, so this approach was not entirely correct. On the other hand, connecting your own voltmeter to each bus is also not very correct, because the voltage on them will also vary depending on the load. For correctness, you need to calculate the average load on the channels, but in this case, the stand needs to be radically finalized, and at the moment I am limited financially and in time. In this regard, I decided to conduct only a test for the maximum load that this PSU can give out and a test of a separate 12V4 line, as the most powerful, with all the measurements. nine0007

So, three samples with different loads on three channels:

The maximum power that the Straight Power 11 650W PSU could produce was about 750W, the total current consumption on the three channels was 60.5A. At the same time, about 826W is consumed at the «input»:

As you can see, the voltage on the 12V1 bus practically does not sag and does not depend on the load on the other buses. But if you measure the voltage at the output of a particular bus (on the block), then with an increase in load, the voltage will decrease slightly. nine0007

Next, the second test with the maximum load of one channel and an approximate calculation of the efficiency. As an example, load the 12V4 bus (GPU) with a current of 5.2A. At the same time, the voltage at the output of this bus is 12.36V, and at the outputs of neighboring buses 12.39V:

Judging by the characteristics, the maximum current for the 12V3 and 12V4 buses (for connecting video cards) is 22A. Current protection (OCP) works at around 35.5A:

In my opinion, a little rough, but it works correctly. At the same time, the voltage sags only to 12.15V (on the other channel 12.38V), so we can argue about fairly good stabilization. Roughly speaking, this bus was loaded with about 426W and the efficiency was about 93.5%. By the way, in practice, loading one bus more than 300-350W is rather problematic, because the “hottest” top cards in stock consume only 250W, and slightly more than 300W during overclocking.

As for the output ripple, in no-load mode on the 12V bus, they average 6-8mV (peak-to-peak 14mV):

At maximum load, the ripple level was 15mV (peak-to-peak 30mV): I’m not mistaken, the standard allows 120mV peak to peak.

Conclusions:

Plus:

• + brand, quality guarantee
• + Modern circuitry and high -quality assembly
