Will this psu be enough?
Iam building a new pc, with I7 950 cpu, evga x58 ftw3 mobo, 3x2gb 1600 ddr3 corsair dominator ram, amd 5570hd gpu, noctua nh-d14 cpu cooler, cooler master 922 haf case, wd cavair black hdd 1tb. Question is I have a new antec 550 watt atx12v v2.3 basiq plus, 80 plus certified psu that I want to use until I can get a corsair 850 watt later. So is 550 watts enough for the moment? Thanks for any replies. I did do the antec power calculator and it stated that I would need about 400 watts but thought I would ask for second opinion.
