Tons of power for high end video cards

Eric L. Fletcher, Amazon
2 July 2013
  • Summary: I used this to replace a lower wattage 3 year old Seasonic power supply. Installation was pretty straightfoward, except for the fact that it did not like the cables that came with the Seasonic. The plugs were just different enough that they would not work. That was rather irritating. Not sure if that's Seasonics fault or Corsairs though. But it puts out tons of power and is quiet enough, even under load.

Ouch!

Beach Bum, Amazon

  • Summary: This psu worked for an hour or 2 and then failed and fried my motherboard... Socket 1366 i havent even been able to find a board yet to test to see if it destroyed anything else. Might want to look elsewhere for a psu. My mind is blown as well cant believe this from Corsair :( UPDATE 5/20/2013: Finally replaced motherboard.... PSU fried both video cards as well.... motherboard = 250$ OS = 150$ ATI 6870 x2 = 500$ TOTAL = 900$ OUCH!!!!

Solid

Jeremy Holmes, Amazon
18 December 2012
  • Summary: This thing is solid. For most people, power supplies aren't like CPU's or video cards. There are no benchmarks to run, no overclocking, tweaks, or other testing to be done. You install it, and it either works or it doesn't, so there's not a lot for me to say. It's quiet, my machine runs cool, and most importantly, it's stable. Love the fact that it's modular. I will never go back to a non-modular PSU.

Small but powerful

Jeremy, Amazon
2 December 2012
  • Summary: I've been running this PSU for about a week now. I'm very happy. Pro's This PSU looks great with my build, fits perfectly in the case, and leaves me plenty of headroom to add a second GPU in Crossfire at a later date. The modular design makes for cleaner cable management or easy replacement if you want to get the fancy individually braided cables form Corsair. According to my APC UPS the unit is only drawing about 120W at idle.

Best power supply in it's class!

Steven, Amazon
1 November 2012
  • Summary: This power supply delivers very clean, steady, high amperage power for cheap, and does it reliably while I'm working on my 3D renders. I'm a 3D artist, and also play demanding games on the side when I have time, and even when my GTX 580 and my Overclocked 130W CPU are running maxed out for weeks at a time rendering stills and animations this thing does not break a sweat.

DOA

jagocr, Amazon
23 October 2012
  • Summary: Dead on arrival, and I don't live in the US which makes the warranty useless for me. I opened the unit and one of the two main capacitors had a leak, that's not something I would expect on a new power supply. I got it replaced but it wasn't enough. Not working yet. So I've an almost $200 paperweight, I would have expected that a cap leak would have been detected on QA, so if you have my luck you might get an useless power supply.
