Hey guys. Last November I built my first PC and it was running great. Two days ago I went to restart my computer and it turned off but never turned back on. I've tried figuring it out, and my dad and I now know it's a faulty PSU. I bought the "EVGA 100-B1-0500-KR - 500W 80 Plus Bronze Power Supply" and I am getting a full refund. So does anyone have a more reliable PSU? Doesn't have to be the same price (could be more but not too much), around the same wattage, and preferable last more that 7 months lol

My build is:
Intel Core i5-6400 2.7GHz Quad-Core Processor
Gigabyte GA-B150M-D3H Micro ATX LGA1151 Motherboard
Gigabyte Radeon R9 390 8GB Video Card

PS. I kay have put this in the wrong category cause I couldn't find a category for PSU.

650w builds in a good safety margin, you don't need more. As you found out 500w worked but was stressed out and died. A 650w is 30% greater in power output

I believe in overkill when it comes to psu units.
I have the Silverstone strider gold 1200w 80+ gold edition. Pay the extra $75 or $100. Not worth spend hundreds if not thousands on everything else if you just buy a stock
high end range 650w psu.

as you can see under max load that card was pulling 323w.
on a standard 500w power supply some of the 500w goes to the other rails.
so you have 450-470 for the 12v rail. intel newer cpu are 80w.
so your pulling 403w with just cpu and gpu. then there the fans and drives.
so you could be pushing the power supply close to it over voltage shutoff. at most it running hot and hard.
650w or 750w unit going to have lot more over head on the 12v rail. the unit wont run as hard.

sinxarknights recommended a 650W PSU. Does anyone have a PSU in mind that is more than 650 (now i want to have a much larger wattage than needed on the PSU just to be safe)

Depends on the protection circuits, higher quality units have very good protection so in the event of a failure the chance of frying something else is greatly reduced. However cheap crap units tend to have next to no useful protection

It isn't low. It has more to do with quality: there are very few 500W PSUs of adequate quality on the market and that makes it easier to simply recommend overkill PSU ratings. That said, junk brands and models tend to still be junk regardless of how seemingly overkill their power rating might be for a given application.
