Great while it lasted

  • Summary: This goes without saying. Power supplies die over time. It took this one 4, almost 5 years to not be usable anymore. Luckily, the 7 year warranty was a major help. Since this power supply is now discontinued, I got a replacement 860, whopping 10 watt difference.
  • Pros: Never had any problems until a few months ago. This was powering overclocked i7 2600k and 2 GTX 580's, 2 SSDs, dual monitor (one 120hz, one 60hz 1080p).
  • Cons: The power supply would provide power but eventually lead to power instability. Part of the reason for such a late review. 4-5 years later, my new motherboard would not power on/POST because of the unstable power. I replaced the PSU to verify this issue.

  • Cons: Not cheap.

RIP

  • Pros: Reliable and worked great for 2 years!
  • Cons: PSU died! After 2 years of use system would only power up intermittently. Thought it was a mobo issue even though it was 2 years old as well. Took it to a computer store where the technician found it to be the PSU. Normal life expectancy should be around 3-5 years from what I've read depending on...

Fan Died

Anonymous, Newegg

  • Pros: Love having a modular PSU for the sake of cable management. More than enough power. Just as easy to install as any other PSU. After the fan died I didn't get it fixed and it still works fine haha.
  • Cons: Fan died after a week.
