So after 10 years of building on single rail PSU's i decided (lord knows why) to use a multi rail PSU this time. http://www.evga.com/Products/Product.aspx?pn=120-G1-0650-XR Now the question i have is that across the rails it supports up to 53A. I have just purchased a Sapphire R9 290 Toxic, im aware through google research the PSU will be fine with this as it has the Amps to do it. My question is do i need to spread the connections across the rails? so use 1&3 rather than 1&2 to keep the load even and safe?
