Okay, i've read like 13 posts regarding power, and was contemplating expanding my rig. The parts are in the mail for my rig (should be getting them in a day or two) I have a kill-a-watt, and could probably figure this out myself in a week, but i wanted to ask here so I could be proactive and order parts to enable a 5th card. (if possible) So, heres the question: Running this rig:
Mobo: ASROCK 970 Extreme4 CPU: AMD Sempron 145 (single core) RAM: 2 x 2GB DDR3 PSU: Seasonic Platinum 1000w 4 x MSI R7950 Twin Frozr
I assumed the following: Mobo, CPU, RAM & one 7959 = 300 watts. Each additional 7950 = 200 watts. So system laid out above should equal 900 watts is the cards are slightly undervolted. Do you think I am correct (or incorrect) in assuming I will (or won't) have the power for a fifth card? (1100 watts?) Would I need to upgrade to a platinum 1200W?
BTW, three cards are running unpowered risers, and one x1 slot is using a powered riser. i assume adding a 5th would require a powered riser.
