1000W-1200W Roundup: Five High-End PSUs
by Martin Kaffei on December 9, 2010 1:20 PM ESTCougar GX G1050
Cougar is a retail brand from HEC, and they sell some cases as well as many PSUs in EMEA. To export their products to the USA they started a marketing campaign a few months ago, which is why various tech sites have seen samples of late. AnandTech received their newest 80Plus Gold PSU from the GX-series (G for Gold). This series has PSUs rated at 600, 700, 800, 900 and 1050 watts; our test unit is the highest rated G1050 model. Cougar has two designs, one with a single transformer and two transistors, the other with two transformers (one switcher each) and an interleaved PFC; we will be looking at the latter.
In the GX G1050 box we find some mounting screws, cable ties, a power cord, a manual, and the modular connection cables. Besides the high efficiency, their robust case and special cable sleeving are the most interesting features. Moreoever Cougar told us that ripple and noise is low because of the CLC filtering; we'll test that claim shortly. The PSU case has a length of 18cm.
| Cables and Connectors | ||
| Fixed/Modular | Main | 24-pin 60cm |
| ATX12V/EPS12V | 8-pin 60cm + 4+4-pin 30cm + 4-pin 30cm | |
| PCIe | 6x 6/8-pin 50cm | |
| Peripheral | 4x SATA 50-95cm + 1x Molex 15cm / 4x SATA 50-95cm + 1x Molex 15cm / 4x SATA 60-110cm | |
| 3x Molex 50-95cm + Floppy adapter 15cm | ||
Two peripheral cables have SATA and Molex connectors; overall Cougar offers 12x SATA and 5x Molex. There is a very long cable with three different types of CPU connectors. This is good for just about any kind of mainboard, but three separate cables would be better. Most readers don't need more than one 4+4-pin connector and want to disconnect the other cables.
The GX fan has seven thin fan blades and comes from Power Logic, with the product number PLA14025S12M. It's a 140mm fan with a fluid dynamic bearing to provide increased longevity.
We have dismounted one part from the heatink on the secondary side to show more of the circuit. This Cougar design has DC-to-DC, synchronous rectifying, and more components than the smaller design used for the GX 600W. The main caps are from Japan while the other ones come from Teapo, a standard choice for HEC. There are many similarities to the AeroCool unit, largely because of the same EMI- and output-filtering. The rectifier bridge from Diodes Incorporated has its own heatsink and the wire cross-section of most cables is big.

nice roundup though the outcome was predictable. I would have like to see some other heavy hitters other than antec included, i.e. mainly corsair, but also enermax, pc p&c, and maybe silverstone.I've been using mostly antec psus in my builds for a while. I like their low end series supplies, and the earthwatts series. I am running the SG850 in my personal rig. For my next personal workstation I plan to go bigger (dual socket). The antec hcp 1200 performs great by all accounts, but I have to say I would prefer a fully modular supply on a high end unit. The only thing I disliked about my SG850 was the cabling; it was also a pain to re-sleeve.

Am I to understand that you want the fully modular cables for ease of sleeving?Thanks for the feedback!

It would be nice to have a psu I didn't feel like re-sleeving. The sleeving on my sg850 was pretty atrocious. The hcp 1200 is a bit better.I'd also like fully modular because it's easier for me to make custom length cables, and not have to deal with hiding extraneous hard wire cables. My sg850 has both 4 pin and 8 pin 12v eps cables. Who needs a 4 pin eps cable on a high end power supply? At least make it a single 4pinx2 connector.
The other advantage to fully modular cabling could be in balancing load across the rails as I need or want.
I'd be happy paying a premium for an hcp1200 with fully modular connectors.

The other comments are right, seems like a bunch of bigger names often synonymous with quality are missing from this review. You guys only review what the manufacturers send over for free now or what? I don't think I would buy any of these...racerx_is_alive - Thursday, December 9, 2010 - link
Thought it was kind of interesting that while the article mentioned the AeroCool's amazing carbon fiber exterior more than once, there were no pictures of that exterior in the whole article. Maybe that was to dissuade us from buying a terrible power supply based on looks? :)Also, in the Cooler Master review, it says that the fan has 7 blades, when in the picture it has 11 or something like that.

I took the plunge and bought 3x 27.5" 1920 * 1200 monitors for use in an NVIDIA 2D Surround View setup and it's rejuvenated my love for gaming. I have 2x GTX 470s in SLI and need to add a third to be able to play all the games I want to in full triple monitor 6180 x 1200 resolution (bezel adjusted).I need to upgrade my PC Power & Cooling 750W PS to accommodate the extra power for the third card and this review couldn’t have come at a better time for me.
I’m not a trust fund baby, just a lowly network administrator at an upstate NY community college who decided to invest a few extra $$hundred (okay, maybe a couple “few extra $$hundred) and try the world of Surround View gaming. I can’t recommend it highly enough if you’re a PC gamer.

Did Antec pay for this review? Seems odd to include only bad PSUs for comparison. I.m guessing Antec chose the PSUs to test.Martin Kaffei - Friday, December 10, 2010 - link
Not true.In a payed review you would see a Gold Award. ;)
I'm sure there are more good PSUs and there will be more roundups in future. Maybe there is a PSU, which is better than Antec. Who knows. But I have to say, Delta is actually a very good manufacturer. So it is more the work of Delta I like, not the ideas from Antec. The cable management needs some improvements.

Kind of a dark horse pick I guess but I'd really just like to see some more 'ink' on Powercolor's 1000w design because well, I haven't heard a bad thing about it yet, and the price is right.ypsylon - Friday, December 10, 2010 - link
Any PSU review without obvious king of the market (Corsair) is completely pointless.Who, in the right frame of mind, will buy AeroCool, Cooler Master or OCZ when Corsair cost is exactly the same or much less (at least where I live), Corsair offers superior performance in every price range when compared to any competitor, absolutely astonishing customer care and equally superior quality. It is complete no-brainer!
In all honestly I would buy Tagan, Thermaltake or Enermax (even if I had some issues with them) over AC, CM or OCZ every single time.
