5 out of 5 eggsBest PSU I've ever owned

Pros: Lots of cables, 12V rail is very strong and handles more than what it's rated for with video cards. Currently running 2 GTX 560's in SLI under 6 core processer for 3 yrs. I do believe proper power is why components last longer and this power supply is no slouch.

Cons: None so far after 3 yrs of faithful service.

Other Thoughts: Although the 850W rating seems a little low for some considering what components I am running, the 70A 12V rail is overkill for my hardware and all the accessories.

5 out of 5 eggsWell worth it.

Pros: Very good looking (if that matters to you), put out a lot of power...

Cons: None Reall

Other Thoughts: I run crossfired graphics cards, a 3rd GPU, 5 HDD, an optical drive, my CPU, and about 14 fans on this PSU.

Also, all my components (RAM, CPU, GPU) are overclocked very heavily, and this power supply hasn't slipped once in over 3 years.

5 out of 5 eggsGreat PSU

Pros: AWesome PSU. Have had this since 11/2009 and it's still going strong. Spent most of its career powering an i7 920 and a 5770 in a P6T Deluxe. Now it's going to power my i5 3570K, and I feel confident it will keep going for some time to come.

Cons: None

Other Thoughts: Substantial PSU. Too bad they're discontinued.

5 out of 5 eggsStill Kicking

Pros: Purchased this Feb '11. Runs like a champ. Writing this review as I plan to upgrade my system. This however, will not be upgraded. Fantastic that its still running the show.

Cons: None that I am aware of.

Other Thoughts: Feels pretty solid, as I have moved three times in the last few year. Definently got banged around a little bit. (Sadface). Though happy to report, still runs like a spring chicken.

2 out of 5 eggsI can see why it has been discontinued!

Pros: It looks nice, comes with plenty of connections, and the wires are sleeved in black, all of which are quite nice.

Cons: It isn't built to last. I have had mine for 4/1/2009 , a little over five years and it's already causing power failures do to broken/melted components. One of the 24-pin connectors is missing a pin, and one of the 8-pin connectors melted and broke off. I have since been forced to switch back to my old 350 Watt PSU--which is already working better than this one.

Other Thoughts: Aside from it causing power failures and not lasting more than it should, it was a decent PSU for a limited time.

5 out of 5 eggsworking for almost 4 years!

Pros: I believe I bought this power supply from Best Buy in store. the great news is that I purchased it around January 2010 (verified by looking at my newegg.com order history and the rest of the pc parts are all on that list except for the power supply), well its 8-23-2013 so 3.5 more months and it will be about 4 years since this has been running in my pc. I have never had one run this long and trouble free. heres the specs of the rest of the system. note: all of the other components of this system have also given me about 4 years trouble-free use. I built this pc for gaming but actually ended up playing r2: yuri's more than 3d games. the cpu can be 4 core unlocked but also I never unlocked it in bios.
