What's the minimum power supply I need? I have seen places I'd be fine with a 900W PSU. Time to ask you guys!
-Oc'd i7 2600k (aftermarket heatsink)
-4 case fans
-2 Asus GTX 580s
-Asus Maximus IV Extreme-Z motherboard
-2 1.5 TB 7200 RPM Hard drives
-16 GB of DDR3 1600
-Possibly a RAID controller
I won't be benchmarking this thing 24/7 or anything.. just probably about 2 hours a day of extreme gaming.
So my question to you guys is, will an Antec Gaming Series 900W psu power my system?
According to Anandtech, GTX 580 in SLI draws 777w in Furmark I would go with something 850w minimum closer to 1000w ideally. That way you have extra juice to add more fans,overclock, hard drives, and the PSU won't be working too hard while gaming.
The Corsair AX850 is based off the Seasonic X series which is heavily overspec'd compared to the actual power it can give off. IIRC, the original X850 can put up over 1000watt's and still remain in spec.
