Although it's an 850w 80PLUS Gold, I've heard some doubt about the PSU. I currently run a gtx 580 and an i7 960 with absolutely no power issues, and it's been that way for a year. Should I upgrade just to be safe with the time, I plan on keeping my new build with 660's for a few years.
I was thinking the same thing, haven't really found any bad reviews on my PSU. I guess Raidmax isn't the most credible company when it comes to customer support, but I haven't had any issue at all with my current PSU and it doesn't seem like their products themselves are sketchy
