I dont know much about PSU's at all but i ordered a pre built computer with an i5-4670k and a gtx 770 along with a standard 600 PSU. so literally everyone told me I picked a crappy power supply. The watts was fine, but the quality was doo doo is what I heard. So I quickly contacted cyber Power and asked for their opinion. They didn't help at all, and they didn't seem to care. So I asked around and I ended up going with a few watts more to give me that extra breathing room. I also upgraded to a name brand. I went with a 650 Watts - Thermaltake SMART Series SP-650PCBUS 80 PLUS BRONZE Certified Active PFC Power Supply. Is this a good power supply? Should this be good and perhaps future proof for future single GPU upgrades? Hows the brand and quality?
