5 out of 5 eggsReview update

Pros: - 900 Watt power supply!
- Many SATA connectors, as well as others

Cons: - Non modular, but it's posted
- Was expensive when I purchased it.
- MOV to boot, was originally scared that it didn't have this until I researched a little further.
- My experience is that it's quite

Other Thoughts: I've had my computer up and running since late Oct 2013 and so far so good. I havn't had any problems out of the unit and it's quite.

5 out of 5 eggsOver 1000 watts on the 12v rails

Pros: Amazing power output. Over 80 amps on the 12v rail.
I ran four 5830's overclocked at full load on one of these babies Bitcoin mining 24/7 for months.

I then took the PSU and it's currently running a Kncminer Jupiter at 660+ GH/s
Amazingly awesome. I paperclipped it with a resistor and the PSU is going strong to this day. So it's been running 2 years, hasn't given me an issue yet.

The fan stays on even after the power has been removed for a solid 1-2 minutes to cool the PSU off.
It's near silent.

Cons: There are so many cables, it's like medusa's dreadlocks hang out of this power supply. Not really a con if you have good cable management.

5 out of 5 eggsworking good

Pros: the fan stays on after you turn the computer off to evacuate the excess hot air out and for a faster cool down
it puts out plenty of power to run my phenom x6 clocked at 4.2ghz and 4 120mm casino blue fans and asus light scribe dvd drive and 800gb advanced format drive

Cons: the only con i could have is its not modular

Other Thoughts: i would buy this power supply again anytime

5 out of 5 eggsStill running strong!

Pros: After running them for several months at near full load I can say that this is a very capable power supply, and can can actually output nearly 1,200w with no issues. High quality build and never had an issue with several units.

Cons: None really, maybe the brightly colored orange power plug and not being fully modular.

Other Thoughts: Got half a dozen of these units for specialized power intensive computing tasks and they have not failed yet after months of 24/7 use, would recommend.

4 out of 5 eggs

Pros: Works great!!
Very sturdy!
Though non modular, the cables are sturdy and it's all pretty durable.
Plenty of power, as the 900 watts isn't the peak of this power supplies abilities.

Cons: We all know it's non modular, it's listed this. But the only real con I have is the price. But I do believe that the price has dropped since my purchase a whole lot, so I was ripped off, lol.

Other Thoughts: I'm still very satisfied with this purchase. Got scared when I read about some pc power and cooling parts don't have the MOV, but thankfully this model did. I'm happy with this purchase overall

5 out of 5 eggsAmazing PSU, as expected

Pros: -Quiet
-Powerful (actually rated for 1050 watts peak, even though it's advertised as 950 watts)
-Plenty of connections
-Quality name & warranty
-Efficient, just shy of gold even though it's listed as silver

Cons: -Not modular, but not a big deal at this price range

Other Thoughts: Used this to run both a 3xGPU rig as well as an ASIC.

1 out of 5 eggsHad to RMA

Pros: I like PC Power and Cooling power supplies. I have several and they all work great. I had a 750 go out on me during warranty and the RMA process with PC Power was smooth. They fixed my PSU for free and it's still working great a year past warranty. I had a heavily worked 1kw model that died a few months after it's 5 year warranty, but that thing worked very hard in a gaming rig so it did its job well.

Cons: I'm having to return the 950w model to newegg. The PSU worked fine, but it didn't shut off properly. This unit is NOT supposed to run the fans for 2 min after shutdown. Mobo bios did NOT have controls enabled for controlled cool down.

The 950w would often turn on the moment power was applied to unit, and when shut down computer would turn off, but PSU would remain on for 2 minutes and would power fans directly connected to mobo and fans connected to molex cables. I spoke to a PC Power and Cooling tech who confirmed the unit was defective based on my description of how the unit was operating.

Other Thoughts: I was going to accept a replacement, but apparently newegg doesn't have anymore so they will refund price and tax. I'm out original shipping. Newegg paid for RMA shipping.

5 out of 5 eggsGood quality but...

Pros: This power supply is built well. I've come to trust the name PC Power & Cooling over the years; time will tell if their recent buyout will change their quality standards.


Cons: I've been building computers for the past 20 years and, I've never had a psu with SO MANY POWER LEADS! This can be a good thing if you need them; however, if you don't need 6 sets of PCI-E cables, 2 8-pin e-ATX cables, and 2 legacy 4-pin molex cables, you are in for a frustrating world of hurt when it comes time for wire management.

Don't simply disregard the reviews on here (as I did) that talk about all the cables this thing has - wire management was easily the worst part of my build.

5 out of 5 eggsBuy this PSU

Pros: I've had it for just about a year now. Used it everyday for hard core gaming. It protected my computer from a lightening strike.

Cons: No cons after a year of heavy use. Even after leaving my system on for 2 weeks straight.

Other Thoughts: It's perfect for Crossifre/SLi, It fits in Define R4 Series cases, leaving plenty of room at the bottom for 140mm intake fan beside it.
