Now I'm a firm believer in having a PSU that has overhead in it. I'm waiting about 7 more days to order my GPU which is the 780 Classified. In this time I'm of course drooling over reviews and so on. I noticed the Power consumption under full load was about 370+Watts. This concerns me. I have a pretty bare system no real extras. In-fact I have built this same system twice. i5 3330, Kingston 8 GB DDR3 1600mhz Ram, DVD-RW, 2TB WD HDD, and soon to be running a GTX 780 Classified. The motherboard is really nothing special infact is sucks its a B-75 Chipset. Anyway my worry is even though whith such little need on power consumption for my system that card draws a lot of power under load as much, if not more than the 780 TI and the Ti Classified. All my system is run on a 600W EVGA 600B with a max output of 49A on the 12V Rail which for the classified is plenty. Should I really be worried I mean I know it will handle it but would it be under powered at peak times?

gpu 370w/12v=30.8a
cpu 84w/12v=7a
memory and chipset tdp= no more than 6a(even less since its a b85)
this totals a max system draw of 43.8a
your psu pushes 49a so you have 5.2 amp of over head with your system pushing max consumption (really never will)
since you cant overclock your setup should be fine and there shouldnt be any situation where your cpu and gpu are at 100% usage so i wouldnt worry

thats why they are insulated if it was a low end no name company then yea i would be a little worried. and evga isnt the best brand but its better than most so i would assume they test the insulation for the amperage current on their cables
