Hi, I just bought a new motherboard and I'm planning on filling it with 4x Gigabyte/Sapphire 7950's 3gb to mine Scrypt but I'm unsure what kind of draw all 4 of them are going to have.
What size power supply would I need for that kind of horse power and can anyone name some top end brands for me?
Thanks in advance.
Each AMD HD 7950 draws 185 W, so 4 X 740W.
You will also need to take into account the base hardware (Mobo, hard drive, dvd drive, ram , and CPU) ...generally the base hardware stuff takes about 230 W. So I would say, you may need a 1000W PSU or 1200W if you want to be really safe.
The 185 W figure is from:
