2 out of 5 eggsWorked for a Week, otherwise great PSU, just got a bad one

Pros: Semi-Modular
Plenty of cables (especially PCI-e and SATA cables)
High wattage for decent price.
Good safety features: Automatically adjusts for power fluctuations from wall outlet. Auto-shutoff for power spikes or other anomalies that could damage components.

Cons: I seem to have gotten a bad unit, thankfully it didn't ruin anything in my PC. Annoying to have to wait an extra 1-2 weeks though on top of the week I waited to get this (old PSU died). Never fun to not have a desktop for 3+ weeks.

Only 1 Molex cable (with 4, 4 pin Molex connectors), not really a con, just a warning; of course most people don't need that many Molex connectors.

Other Thoughts: The cables are fantastic, it's only semi-modular but that's fine since the integrated cables are all ones you'll use anyway (motherboard cable, CPU cable, 2 x 6(+2) pin PCI-e.

There's 4 12V rail module connectors for SATA and Molex connectors. Each cable has either 3 or 4 individual connectors which is fine. Easily enough to power all the components in any PC. Also comes with 4 modular connectors for PCI-e connectors. I believe you could easily connect 3 beastly GPU's, each requiring 2 8 pin PCI-e connectors for power, so that's great.

While the safety features are great I feel this is what caused my issue. My PC worked fine for about a week. Then it would randomly shut down about 4-9 minutes after booting up. No warning, no nothing, the entire PC just shut off. Did this about 6 times before I finally gave up. The odd thing is after each time it would briefly start-up again and enter the BIOS splash screen, then immediately shut down. The really frustrating part is that it would then REFUSE to power back on without a LOT of fiddling with unplugging it and switching the PSU on and off. Even tried it in a different PC (and outlets) and the same thing occurred, yet the swapped PSU powered the victim PC just fine, so clearly isolated it to this power supply.

If this issue happens to you RETURN IT. Don't waste your time checking the wiring or trying to get it to work just to have it constantly fail, just RMA it. I spent hours thinking I wired it or my motherboard incorrectly, or didn't divy up the rails correctly, nope. I tried every correct solution and nothing worked, on either of the two PC's I used.

5 out of 5 eggsThis thing purrs, a little too much, but I love it!

Pros: Modulator design makes every thing easier. The cords are as long as they should be. Powers my rig (Asus Rampage Extreme 4, R9 270, Intel i7 - 4820) without issue.

Cons: Kind of noisy, but I don't care about that. Nothing else comes to mind.

4 out of 5 eggs

Pros: Looks nice, it matches my red and black color scheme. It's also very quiet.

Cons: It only came with one x4 four pin molex cord and it wasn't very long. I had to move my fan docking bay circuit board over to accommodate the shorter cord. It's a good thing I didn't have very many 4pin connectors BC I am using 3/4 of them. Also the PCI cords are hard to deal with.

Other Thoughts: I would buy this product again. I just wish they would make better cords. A good deal for 100 bucks for a thousand watts.

5 out of 5 eggsNice PSU

Pros: This PSU has so far been up to the task for me. My machine isn't ultra high-end:
AMD FX8350
2x AMD R9 285's
16GB of RAM
Blu-Ray Burner/Drive
2 HDD's
Far too many USB peripherals

So far the PSU has given me no trouble whatsoever. I have it mounted with the fan facing down (my case has vents on the floor to allow for this). I haven't had any problems with my fan making noise, rubbing or failing as others have reported. That's not to say other reports are illegitimate, just simply that mine has not had this problem.

So far mine has been up to the task and doesn't run particularly loud even at full load. Of course, this is based on what my computer throws at it, which is probably not the full 1000W's it is rated for.

It also looks very nice and the construction quality seems to be pretty decent.

Cons: Nothing so far aside from the lack of a case badge. Call me strange, but I like to slap the stickers from my various components on the case and unfortunately this was pretty much the only core component that did not come with one.

Other Thoughts: It does the job as far as I have seen. Is it built as well as the top tier expensive PSU's? Likely not, but it still seems to be well above the bargain PSU's.

5 out of 5 eggsLooks orange but it's actually not

Pros: This partial modular powersupply is beautiful. I was worried that the color wouldn't match the rest of the computer I was building but I'm happy to say the picture doesn't do it justice. The black and red scheme looks almost like a metal flake paintjob with matte black to make the red pop. Other then that it's a power supply it hasn't blown up and it worked out of the box so what else could i ask.

Cons: If i had to give a con it would be that the cables that come with it for the modular connection gave me a lot of headaches. the 8pin connectors have the 6 and 2 design I hate. the sata power cables all seemed to have the connectors upside down (for the way i was building) took a very long time to get all the cable management under control. I also wish the perment cables were on the right side of the powersupply instead of the left so they would have been easier to hide away. minor gripes though it's a truely awesome supply

Other Thoughts: I don't regret buying this supply for a second. Neither will you! for the money I'm pretty happy.

4 out of 5 eggsBang for the money

Pros: Running 2 GTX 770 with FX-6300 OC @5Ghz. It's running perfectly.

Cons: Fan is hitting the grill when my PC is under heavy load. It stopped doing it now when I moved the grill a little.

3 out of 5 eggsWell-priced entry into the kilowatt range, but with issues

Pros: Got this on sale, and it was among the lowest-priced 1000W PSU available. For larger systems, this PSU provides six quasi-independent 12V rails (think graphics cards), but use of the 12V rails has to be carefully planned if the PSU is supposed to run under near-full load: only two of the rails provide 28A (336W); the others only 24A (288W). Interestingly, the total load on all 12V rails is as high as 960W, according to the specs, which is pretty good.

The almost-full modular cable management is a plus, although the main power and CPU power cables are not modular. Sufficient cable choices are included.

This PSU has run under almost full load (measured 1000W input, probably 800-850W output) for over a month, and it has not failed.

Cons: The worst problem is the fan. Other reviewers already highlighted a design flaw that the fan scrapes the grille in a fan-down mounting position (i.e., any case where the PSU is mounted above the board). This is unacceptable, because the problem is known to Cougar, according to one reviewer.

Staying with the fan, it is absolutely not quiet, even under no load (i.e., room temperature). If the PSU runs under high loads, expect significant sound emissions. But then again, this fan would only be one of several loud fans in such a system.

Even worse, when I modified the fan assembly slightly to increase the distance to the grille, the scraping stopped, but the fan started some form of death rattle -- again only in the upside-down position. I replaced the fan by a different product (more cfm, less noise), and the fan issues are now solved. Note that any such action voids the warranty; I was unwilling, however, to deal with the RMA process.

Another problem is electronical -- a load change on the gaphics cards causes a noticeable flicker in the room lights. Either the primary sieve capacitors are underdesigned, or the PFC electroncis causes considerable load transients. Whichever the cause, it is a design deficiency.

A minor con: Although the cables are sleeved, the sleeve appears to be some form of plastic shrink tube. It gives a cheap impression, and in addition makes the cables more rigid than necessary.

Heat dissipation is another interesting aspect of the PSU and, by extension, the overall system. Something that draws 1000W requires a well-vented space, because a small room would quickly overheat. OK in winter, but a serious problem in summer. This PSU claims an efficiency of 87% under full load, meaning, it would dissipate on its own some 130W, this is as much as a small hairdryer on medium setting.

Other Thoughts: As usual, you get what you pay for. This is a low-cost work horse. I'd probably feel more confident if I could use it on a computer with lower power consumption, but this one has grown over time. It is generally a good idea to over-dimension the PSU as to not run into any power limitations.

The fan issue reminds me of a different Cougar fan that I reviewed recently, and which also had a much higher noise level than advertised (plus a wobbling motion of the impeller). Perhaps Cougar should outsource their fan dvelopment.

Overall, this PSU is a good choice for the high-end gaming computer, where a potential failure is not mission-critical; for systems that need very high reliability, however, paying some additional $100 may get you away from the "entry-level" feel.

Welcome to the kilowatt club.
