hi, i m trying to built a i7 920 system and i have a question about PSU. I have a thermaltake 700w with combine of 56A. i want to know if this PSU is safe enough to run an I7 920 system with an asus P6T motherboard with, 6gigs of ram, 4 sata hd, 1 dvd writer and a single ati 4870 or g260 video card? i dont think i wil OC the CPU or any another component. but if i were to OC just a little. will this PSU handle it.?? thank you smoke
