Need help determining PSU voltage
I'm having a difficult time determining voltage for my new machine. It's been a long time since I built my last computer and technology has substantially changed since then.
AMD Phenom II X4 940 3.0GHz, , 1 HDD, HD 4870 gpu, and an m3a79-t mobo
this system will also have one dvd rom and two dvd-burners (two of these drives are going to be salvaged from my old computer), a floppy drive, and cpu and vga fans/heatsinks. The case that I'm purchasing is the thermaltake armor full tower. It includes two 90mm fans, two 120mm LED fans, and one 250mm fan.
I'm just having a difficult time calculating everything to determine voltage needs. I know that's not the only thing to look at when determining a psu, but that's what I'm looking at now. Thanks in advance.
