Good day to you all. I'v got a simple question. What power supply should I choose for my rig. I'm planning on running two of these here: GV-R928XWF3-3GD (rev. 2.0) In the near future I will also get i5-4670K CPU. The online PSU calculators say 850W power supply should be enough(I think so also). My first choice is: Thermaltake Toughpower DPS 850W 14cm/80 PLUS GOLD or maybe: 1000W, EVGA SuperNOVA 1000 G2, 80+ GOLD, just to make sure? Please give me some advice. BTW i will use my rig for mining, for gaming maybe after I get bored xD . Thank you.
