We’re always recommending between 600W and 800W for the best gaming PC PSU and be quiet! has the Pure Power 11 FM 750W for even the more enthusiast-grade PC builds. This PSU is designed as a more affordable option for PC builders, rocking a 80 PLUS Gold rating for efficiency.

The power supply is one of the most important components of any system as it’s the device that provides power to everything inside (and outside) the chassis.

be quiet! makes some high-end components for gaming PCs and the company’s loadout of power supplies are right up there with the best. We reviewed the phenomenal be quiet! Dark Power Pro 12, which can efficiently deliver immense power. Even with a more affordable Pure Power 11 FM PSU, be quiet! still uses premium Japanese capacitors that can hit temperatures of up to 105C.

Regardless of which PSU you choose from be quiet!, it’ll be more than capable of powering even high-end systems. This power supply has an 80 PLUS Gold rating, which means it’s 90% efficient at 20% load, 94% efficient at 50% load, and 89% efficient at 100% load. Heat loss is the primary cause for lower efficiency and be quiet!’s design ensures that as much power input is converted as possible.

100% 85% 87% 89% 90% 94%

The Pure Power 11 FM sports the usual be quiet! design in that it’s a solid slab of black metal. At 160mm long, this PSU will fit in most ATX cases, and the beefy 132mm fan will keep the internals cool even when under heavier loads. There are plenty of connections with the power supply. Here’s what cables be quiet! bundles with the PSU:

  • 1x 24/20-pin ATX (550mm)
  • 2x 8/4-pin EPS/ATX 12V (600mm)
  • 2x 8/6-pin PCIe (500mm/150mm)
  • 1x SATA/MOLEX (500mm/150mm/150mm/150mm)
  • 1x SATA (500mm/150mm/150mm/150mm)
  • 1x SATA (500mm/150mm/150mm)

The fan is almost silent at low load and while be quiet! didn’t work in a zero fan mode, you will struggle to notice any noise terminating from the PSU unless you really push the system hard. In terms of performance, we didn’t notice much in terms of fluctuations while pushing the PSU hard in demanding tests.

With an AMD Ryzen 9 5950X CPU and NVIDIA GeForce RTX 3070 Ti GPU, we struggled to spot anything out of the ordinary. be quiet! Pure Power 11 FM 750W adheres to the ATX spec for voltage regulation and you’ll not encounter any issues in terms of performance or reliability.

The five-year warranty isn’t the best at this price point. There are competing PSUs like the EVGA SuperNOVA 750 that come with a 10-year warranty. I don’t expect the Pure Power 11 FM to fail at any point during (or shortly after) the warranty period, but it would have been a good move for be quiet! to offer the full 10 years for added peace of mind.

The competition is fierce, especially for 650W and 750W power supplies. be quiet! itself has a few options available, depending on what PC specs you intend on using, as well as how much budget you have to spare. The aforementioned EVGA SuperNOVA 750 is about the same price but comes with a full 10-year warranty, which is a great upgrade for those who want a company’s full backing.

be quiet!’s own Straight Power 11 750W PSU can be bought for around $30 more and has an 80 PLUS Platinum rating, the next step up from Gold. There are various modular PSUs available and none of them would be a «wrong» choice. It all comes down to the required power output, desired warranty coverage, and price.

high-quality power supply for $55 / Cases, PSU, UPS, case cooling, surge protectors / iXBT Live

The review of 350 W power supplies, which began with the most budget models (1 and 2), continues with the product of the German company be quiet!, specializing in the production of quiet PC components.

The Pure Power 11 range includes power units from 300 to 700 watts. Models from 400 W and above are certified in the 80 Plus Gold class, and our test subject, like his younger brother, has an energy efficiency level of 80 Plus Bronze — this is due to circuitry, but more on that in the appropriate section. 9Ol000 ! are painted black and differ only in the features of the series and sizes.

Package dimensions (W×H×D): 263×210×100 mm

Weight: 2.15 kg

Pure Power 11 350W protects against the vicissitudes of fate in a bubble wrap bag.

Kit includes: power cord, five plastic ties, five fixing screws and quick start guide.

The body is made of steel sheet painted with black matt paint. A stamp is stamped on one of the sidewalls.

The air intake grille is made of bars — this solution creates minimal resistance to air flow.

Product dimensions (L×D×H): 150×150×86 mm

Weight: 1.68 kg

Heated air leaves the power supply through large honeycomb holes on the back of the case.

The cable outlet is framed with a half-ring made of soft plastic.

A small ventilation grill underneath helps cool the low voltage part of the unit. You can read more about this feature of the series in the be quiet! Pure Power 9 500W (section — cooling system).

Cable management

Pure Power 11 350W — non-modular power supply, that is, non-removable cords.

For ease of laying inside the PC case, the wires are pulled together with black nylon nets. Standard wire gauge is 18 AWG.

Cnipodes Number Wire length, cm

The number of connectors more than adequately block of the unit: Five SSD/HDDs can be connected to Pure Power 11 350W, a couple of corps cards and, for example, sounding cart . You can also connect a video card with an average consumption.

The length of the cords allows you to hide wires in small towers with a lower PSU location, as well as in cases for multimedia PCs.

Passport data

be quiet! Pure Power 11 350W is connected to an AC mains with a voltage in the range of 100-240 V. This will allow the unit to work with very significant drawdowns in the mains voltage.

Two +12V channels combined for 336W of power. This is a decent figure for a PSU with group stabilization.

Lines +3.3 V and +5 V in modern PCs are much less in demand — a total of 110 W is enough with a huge margin for any system.

Circuitry

Pure Power 11 350W (like Pure Power 11 300W) is built according to the group stabilization circuit — the +12 V and +5 V channels depend on each other — if the voltage on one sags, then on the other it rises , and the +3.3 V line is stabilized separately. The older models of the line have separate stabilization — otherwise it is difficult to achieve an efficiency level of 80 Plus Gold.

Block OEM is FSP.

Neat assembly.

Stages of current transformation are indicated by numbers:

  1. Input outlet/Electromagnetic interference filter
  2. Two -sulfur current
  3. APFC (active power factor) and high -voltage condenser
  4. Calles
  5. 9000
  6. 9000
  7. Secondary rectifier
  8. LC filter

Part of the noise filter is soldered to the socket — two Y-capacitors and an X-capacitor. On the latter there is a scarf with a resistor for discharging the capacitor after the power is turned off (located on the reverse side of the scarf). A protective diode is soldered on the front part.

Mains voltage is supplied to the main board through wires passed and wrapped around a ferrite ring.

A couple more Y-capacitors, an X-capacitor and three chokes are soldered on the main board — the rest of the noise filter.

The protection circuit has a fuse in a plastic casing and a pair of gas dischargers — on both sides of the throttle, the first from the input. The varistor is not soldered, although a place is provided for it.

AC rectified by Taiwanese HY Electronic GBU 806 diode bridge (600V, 8A @ 150°C). It does not have a radiator, and it is not necessary — the parameters are taken with a margin, the power of the unit is small, the heating will be small.

The choke coil of the active power corrector has decent dimensions and is wound with thick wire — this is good.

The capacity of the Taiwanese brand Teapo electrolytic capacitor bank is 180 uF — which is enough for a 350 W unit. The rated voltage of the capacitor is 420 V — and that’s good too. (At the input of the blocks put electrolytes designed for a voltage of 400-450 volts. Much more often at 400 V, but the higher the better.) Operating temperature — up to 85 ° C usually small, this option will do.

By the way, on the technical specification sheet of capacitors, in addition to the Teapo brand, there is the Jamicon logo — at the end of September 2019, these companies merged into one. The quality level of both brands was already quite good before, and after the merger and exchange of technologies, it may have grown.

The microcircuit of the PWM controller of the main converter keys and at the same time the APFC controller is soldered on a vertical scarf and all this is soldered in heat shrink. It is impossible to see the controller, and if there is a chip manufactured by FSP, then it makes no sense — its specification is still not available.

The corrector diode and mosfet are located on a separate heatsink and their marking is also not visible. A ferrite bead on the leg of the diode contributes to the suppression of high-frequency interference.

Main Converter Keys — Pair of 14SL501 Mosfets (500V, 14A) also have their own heatsink.

The rectification of the current coming from the main transformer is performed by Schottky diodes screwed on both sides of their radiator, in pairs for each line. The value of the elements is taken with a margin:

Two diodes PS30U60CTR (60V, 30A) per +12 V channel. controller TNY277PG.

Smoothing electrolytes manufactured by Capxon and Taicon, with temperatures up to 105 ° C and a total capacity of 3000 uF — a good indicator. Manufacturers are also worthy — Taiwanese, and the latter also belongs to the Japanese company Nichicon.

+3.3V, +5V and +12V smoothing uses 105°C Teapo, Capxon and single Taicon electrolytes.

Equivalent capacitance:

  • 4400 uF per channel +3. 3 V
  • 3700 uF per channel +5 V
  • 9900 uF per line + 12 V — on the channel +12 V capacitors are not spared.

    Screwed to the radiator of the secondary: a temperature sensor and a fan speed control circuit on its scarf.

    Output voltage monitoring is assigned to the Weltrend WT7527 chip.

    The soldering is neat, some of the tracks are reinforced with solder and rods. Flux residue is washed away.

    Testing

    Description of the test stand is available here.

    The output voltages of PC power supplies must comply with the ATX standard developed by Intel.

    Voltage tolerances (ATX 2018 standard)

    The voltage above the value of the nominee for the lower one, which will be lower than the nominee — it will be more than the one. load increase.

    The maximum voltage deviations from nominal during testing were:

    • +3.3 V line — 1.2%
    • +5 V line — 0.8%
    • +12 V line — 3.2%

    Good stability — deviations did not exceed 3.2% of the nominal value on the main +12 V channel used. Moreover, even during overload, the voltage did not sag below 12 volts. The rest of the voltages are generally fine.

    The duty line +5 V is perfectly stabilized — the deviations are within 1. 4% of the nominal value.

    The short circuit test was carried out using a thin wire. All channels are protected and in the event of a short circuit, the unit instantly turns off.

    Cooling system

    The fan behind the Pure Power 11 350W is made by be quiet! and bears the marking BQ QF1-12025-MS (12 V; 0.3 A; 1600 rpm). The design uses a fairly reliable plain bearing with a screw thread.

    Due to the low power of the unit, the plate that blocks and directs the air flow is not used, which has a beneficial effect on the noise during operation.

    The manufacturer gives a graph of the noise level depending on the load on the unit and testing confirms it — be quiet! The Pure Power 11 350W is very quiet throughout the entire load range. At a distance of half a meter, the cooling system is no longer audible. No electronic noise was detected during operation.

    Totals:

    be quiet! Pure Power 11 350W is a high-quality quiet unit for computers with low consumption — office, multimedia, gaming with a low or mid-range graphics card.

    be quiet! when choosing a power supply, it recommends leaving a reserve of 30% of the power from the maximum consumption of the system. Based on the above, Pure Power 11 350W can power a PC with a consumption of up to 250W, and this is for example a Ryzen 5 3600X or i5-9600KF in conjunction with a GTX 1650 Super graphics card. Without overclocking components, of course.

    Plus:

    • Good voltage stability
    • TIME ANSTRUCTION
    • Decent set of train and connectors
    • Almost silent work

    Appearance

    Style be quiet! Pure Power 11 CM 600W is well known, the company adheres to the general style in fans, cases, air and water cooling systems.

    The combination of a black case with an orange edging around the perimeter of the fan area. Looks elegant. Other than that, it’s a good classic.

    The fan is protected by a grill grate in the form of a series of longitudinal wires. There is no backlight here, in this matter they remain conservative.

    In the series itself, models with a power of 400, 500, 600 and 700 watts are available. On the back wall there is a power cable socket and a mechanical toggle switch.

    This is a partially modular power supply. Fixed power lines for the processor and motherboard. Protective braided wires.

    A version with non-removable cable management has also been released. This option is expected to be cheaper. Opting for a modular solution has the advantage of removing unused lines, making it easier to neatly stack inside the case.

    In addition, there are two separate lines for powering video cards with four PCIe 6 + 2 connectors.

    Single line with three SATA and two mixed SATA and MOLEX cables. Removable cables have a flat braid. On the manufacturer’s website, you can purchase cables with a separate braid. Section 18AWG.

    On the inner wall there is a row of five connectors for connecting removable lines. They are signed, plus they differ in shape, eliminating the risk of incorrect assembly.

    The cooler (actually not) was followed by a block. This is not an ancient tale of a great migration — this is my mode of operation. Cooler — in the sense of be quiet! Pure Rock 2, which I hope will be awarded a review before this one comes out. But today is not about the cooler. Today is about the power supply. I’ll tell you about be quiet! Pure Power 11 600W .

    Positioning and price

    The recommended price for a German is, as usual, above average. In our case, it’s a hundred bucks, plus or minus. That kind of price successfully crosses the red line for many people who are collecting gaming cluckers for 15.9k0003

    But obviously, if a block costs $100, there must be something there. Given that it’s not even modular. Modular models are designated CM and are slightly more expensive.

    Contents

    The delivery set of the unit is relatively modest. Power cable, instructions and warranty, plus a bag with ties and four fastening screws, well, the PSU itself.

    Visually, we have before us a classic of the German power supply industry. Matte black wherever possible, including the annular part around the grille. If anything, for CM models, this very ring is orange.

    Front cable exit and small perforated area for extra ventilation.

    Rear connector and power button, as well as a large perforated area for ventilation.

    Left — embossed logo towards the observer.

    On the right is the rating plate with technical information. Useful in the economy, no doubt.

    Nothing interesting on top, but below there is a grille with a fan underneath.

    Cables

    The set of cables and their lengths are shown in the picture — right on the box:

    Here is a complete list of them:

    • 20 + 4 pins, 550 mm long
    • 4 + 4 pins, 600 mm long — yes, only one
    • two 6 + 2 pins for PCIe, 500 mm long
    • SATA + SATA + HDD + FDD, length 500 mm + 150 mm + 150 mm + 150 mm
    • SATA + HDD + HDD, length 500 mm + 150 mm + 150 mm
    • SATA + SATA + SATA, length 500 mm + 150 mm + 150 mm

    Of course, a non-modular PSU priced at about $100 will almost come as a shock to many buyers, but this is be quiet!, «creme de la creme» from power supplies and not only, so there is little surprise here. Especially considering that the other distinguishing features of the product are also ok.

    Specifications

    For example, the energy efficiency of 80Plus Gold. Rated power — 600 W, maximum — 650. There is compliance with the ATX 2.4 standard, as well as EPS 2.92. The conversion topology is designed as follows — Active Clamp + SR + DC / DC, with active PFC on top.

    The PSU is built on the FSP platform, with a 330-uF smoothing capacitor from Teapo at 420 volts, STMicroelectronics STF25N80K5 and CET CEF03N8 converter mosfets, as well as a CET CEF02N7G mosfet and a PS30U60CTR rectifier for the 5VSB line. Active PFC is provided by the FPS6600 chip.

    In general, the platform is not budget in any sense, and savings are not noticeable anywhere. Plus, cooling is provided by a Silent Wings fan labeled BQ QF1-12025-MS and a rotation speed of 1800 RPM.

    The peak efficiency of the unit is at the load level under 500 W, and reaches 94%. But already from 150 W it exceeds 90%, and even when receiving an excessive load of about 700 W, it does not fall below 92%.
