My old Sentey 650w power supply got exploded and i'm now on a market to find a new PSU, I have a AMD Phenom II X4 955 CPU and a RX 580 2048P, a N68-VS3 UCC motherboard, a 512GB and 10GB DDR3 RAM, I found 2 choices on Facebook marketplace, EVGA 650W (non-80 Plus, 52 AMP 12 volt rail) or EVGA 500W (80 Plus white, 40 AMP 12 volt rail), Which should i choose? BTW, they both have the 8-pin PCI-E cable i needed.
