Xfx 5970 black edition: XFX HD 5970 Black Edition Specs

Last time we finished with a 700W unit, and now we are opening with a 750W model. It would seem that the transition is scanty, but in fact it is a breakthrough.

To start with, we got 9 rather than 6 SATA connectors and finally 4 separate connectors to power two independent top-level video cards. We already have a real gift for a serious gamer — the owner of multi-chip Cross-Fire or SLI configurations, who, moreover, comfortably (without adapters) will collect a rich collection of game content on an HDD array.
And what about the length of the wires? Everything is in order here, because. the length of the «processor» and «mother» cables is 55 cm, which is enough even for Full-Tower cases with a bottom PSU.
Antec EA 750 — EC is modular, although it must be admitted that there are few detachable wires, mostly non-detachable.

Thus, it turns out that without additional cables it is possible to assemble a PC with a top-end video card, three SATA hard drives and three — PATA. But if you need to connect more hard drives and / or a second top-end video card, then you will need to add «laces to your taste.»

Compared to the BPs discussed in the last article, the loss is only in acoustic properties. Models from Antec were not famous for their silence. Specifically, the EA 750 model can be classified as moderately noisy under a serious load, and without it, the PSU is quite quiet and its work is hardly noticeable in a closed case. ADDA fan labeled ADN512UB-A91, rotates the blades at a speed of 1200 rpm, which is too much for a 135 mm impeller diameter from the point of view of a silence lover.

For example, we can cite the standard — Zalman ZM-850HP, whose revolutions rustle themselves from 600 rpm.
Externally, the PSU looks very presentable, powerful. This appearance will not overshadow the body of any level. All cables are «braided» impeccably, each of them has ferrite rings that reduce interference. The fact that PATA connectors do not have tack lugs is a bit overshadowing, which means that if they are tightly connected, it will be problematic to disconnect them.
Pleased with the «insides». Having opened the block, we observe tight installation, perfect soldering and rigidly fixed cables, batteries, etc. Antec chose capacitors, frankly, not from an expensive Japanese manufacturer, but from an average Taiwanese one — Ltec ​​(Luminous Town Electric Company), however, from the entire line I chose the best — withstanding temperatures of 105 ° C. Other characteristics: voltage — 420v, capacity — 180uF.

One way or another, in real tests, the efficiency of the source exceeds 80%, and the power factor (PF) is brought to 0.99. One way or another, in real tests, the efficiency of the source exceeds 80%, and the coefficient
power (PF) brought to 0.99. Environmental certification 80 PLUS not awarded
in vain. By the way, given that the PSU does not heat up a lot in operation, we went for an experiment,
replacing the standard fan with another, reducing the speed with the help of reobas.
It turned out to be a 120mm Enermax Magma fan. running at 900 rpm
quite enough, the PSU was barely warm even under load. our advice you can
follow you, thus getting an almost silent PSU. EPS12V 2.9 certification compliance1 allow you to use the EA 750 — EC model to «power» entry-level server «mothers». The PSU has separate physical 4 and 8 pin branches for processors with different power needs. The developers divided the +12 V bus into four separate channels, considering this solution the most rational in terms of stability and power quality. The load capacity of each of these lines is 25 A. Well, in general, powering two or three of any top-end single-core video cards will not be a problem. A similar current can be provided to consumers by channels +5 V and +3.3 V, which means — connect peripherals as much as you like, even if all 18 hard drives — the PSU will withstand.

Although we got excited about the latter, the PSU is modular, but there are few external connectors, there are only two branches for 2 peripheral connectors, so there is a choice: 9 SATA + 3 PATA or 9 PATA + 3 SATA, that is, 12 hard drives. Of course, nothing prevents the use of 1PATA — 2PATA type adapters, and this should also be taken into account.

Thermaltake EVO_Blue 750W (W0308)
Is there anything more interesting in the 750-watt camp? There is, of course, the fashion here is set by Thermaltake, which has released a very unusual advanced EVO_Blue series, the representative of which we will now consider.
Maximum load: 3.3V — 30A, 5V — 28A, 12V — 56A, -12V — 0.8A, 5V(sib) — 3A

First, let’s make a comparison with Antec EA 750 — EC, with which the price, by the way, is almost the same. We did not receive 9 SATA connectors this time. There are only 6 of them, although the 5V line is somewhat strengthened (from 25 to 28 A). The increase turned out in the form of the possibility of implementing 4 8 pin connectors for accelerators. Which, however, is meaningless, because in order to power a tandem of two top-end video cards like the GeForce GTX 295 or Radeon HD 5870 two 8pin connectors are enough, the other two can be 6-pin. This property would play in the implementation of the union of 3 or 4 accelerators such as Radeon HD 4870, but such systems are very, very rare.

Meanwhile, the current strength along the 12 V line is lower than in the case of the Antec PSU, although we must pay tribute — Thermaltake did not flirt with the user in marketing terms, honestly writing that the PSU has one line (not 4 virtual) 12 V with 56A. This, however, is enough to feed any two single-core video cards on the market or one 2-core one, including the Radeon HD 5970 in acceleration.
An important plus of Thermaltake EVO_Blue compared to the previous model is quieter operation. The stock 14mm fan on the TT-1425 is stated to run at 1400 rpm, but we thought 1400 was the upper limit, in fact overclocking starts at 1000, which is quite quiet.

At the same time, if you are building a very quiet PC, then this PSU is unlikely to suit you, at night the noise from the PSU fan becomes audible.
Now let’s look at the circuitry.

Its crowning achievement is the Japanese Nippon Chemicon capacitor, which does not lose its working properties at temperatures up to 100 º. In the case of Antec EA 750, the filling was more modest, although it should be noted that Thermaltake EVO_Blue has all other Taiwanese capacitors from TEAPO.
But otherwise, there are solid differences and additions regarding what we saw when considering the Antec EA 750 — EC. First of all, we note the length of the system and processor cables — it is royal — 65 cm, i. e. enough to, for example, pass the cable behind the motherboard and power the processor socket, which may not be located on the edge, but closer to the middle. On the Russian site, the length is marked as 50 cm, but according to our measurements — 65 cm.

The second thing I liked is that all cables (with the exception of one — the processor one) are detachable, which gives complete freedom for interior decoration.
Well, the third, most important feature — not even a luminous fan and not that. that it shines in different colors, and the fact that colors can be selected, or even completely turned off, for which another button is made next to the on / off button.

Enermax Revolution 850W
Move on, add just 100 watts and get a completely different level of quality. And all because EVO_Blue 750W was the senior in its line and Revolution 850W was the junior model. Well, the change of manufacturer makes itself felt. Nevertheless, the main direction of Enermax is power supplies, and Revolution is the crown of creation today.

Small losses

«Eight hundred and fifty warriors of light», «Black mass», «Tiberium for gamers» — these are all the headlines of articles about this PSU.

Both journalists and gamers went crazy, pecking at the attractive, poisonous, fashionable appearance, 45% of which is a toxic fan with a «spider» grill, 35% is a cube-like body that resembles modern buildings and 20% is, of course , in the tone of the fan «honeycomb-houses» for connecting cables. And without highlighting such a PSU in a modding computer, it looks impressive, phosphorescent burning, giving its power to other computer components.

In general, the direct merit of marketers, especially considering that we have before us nothing more than a redesigned Seasonic M12D model, the photo of which you can see.

You can see for yourself that outwardly the blocks differ like heaven and earth, Seasonic looks like an ordinary model. So for modding XFX takes only $25. This is not much, considering that the input connectors have also been redone. XFX has more connection sockets.
Both use Japanese Nippon Chemi-Con Solid Capacitors (105°C). Soldering elements, laying wires, insulating boards, fixing parts with glue — all this is done flawlessly. In operation, at high loads, the whistling of the chokes, which many expensive PSUs like the same Zalman ZM1000-HP have, is almost invisible.

Thanks to its filling and successful implementation, the model received a rare 80 PLUS Silver certification, the block efficiency reaches 88%. That is, only 12% of the power goes to heat the case, which reduces both the temperature and the speed of the ADDA ADN512HB-A91 blowing fan. This PSU can be classified as quiet, its operation in a closed case is not audible at all in 2D mode (the fan speed is spinning at the level of 750-900 rpm).

And during the load, only a slight, non-stressing rumble is created. But still, if we compare it with the quietest PSUs in the industry, the list that we gave above, reviewing the Enermax Revolution 850W, then the conclusion will not be in favor of the XFX model. On the other hand, for an extreme gaming system, the PSU fan should not be too slow. It often happens that the user is playing on a very overclocked system and it is better to overclock here. The main thing is that at night a computer with a working
The XFX 850W Black Edition is virtually silent. Interestingly, the fan is fixed with rubber bushings that prevent the transmission of vibration, we have not yet seen such care in other PSUs.
A 20 + 4 pin cable, 2 processor power cables (8 pin and 4 + 4 pin) are made fixed in the PSU, allowing you to easily power two CPUs at once in EVGA Classified and Intel ScullTrail boards, as well as 2 6 + 2 pin cables for power video cards. The rest of the cables are removable.

Let’s pay attention to the ability to connect up to 11 SATA hard drives without using adapters, in general, there is everything to organize an extended file server in which to store all your favorite games played over the past 20 years.
Without adapters, 4 video cards will also be connected, we would not expect anything else from the gaming spirit of XFX. The current through the line is 12 to 70 A and the power of 850 W is, in principle, enough to assemble a system based on two 2-core video cards such as the GeForce GTX 295 or Radeon HD 5970, using them without overclocking. Or you can assemble a «budget» trio of three GeForce GTX 275. Most often, the PSU will probably feed a top-end video card plus any other for physics calculations or the most successful (price / quality) bundles such as 2 x Radeon HD 5870 (http://www. computerra .ru/terralab/platform/489049/).
As for the length of the cables, everything is in order, at the beginning of the article we have already published a summary table of characteristics.

Results
Antec EA 750 seemed to us a strong middle peasant with an excellent power reserve, a large number of SATA connectors, and excellent appearance. This PSU has no obvious disadvantages, except that the fan will need to be changed if you are building a quiet, and not an average PSU.

Thermaltake EVO_Blue 750W (W0308) — a unique gift for those users who can choose any backlight. However, the PSU will also appeal to those who want to assemble SLI or CF without using adapters. And the backlight, the backlight can be turned off .. and without it, the model is very beautiful.

Enermax Revolution 850W — probably the best PSU in technical terms. Designed for maximalists who assemble uncompromising and very powerful solutions.
