I just ordered a Thermaltake Toughpower 850w for myself, because I just bought a 9800 gx2, and might later add a second. Is this a good reliable PSU, and will 850w be enough for 4gb RAM, Dual core CPU and 2 9800 GX2's?
yeah, this PSU has quad 12+ rail which is good with a combined output of about 96W, this PSU also has the pride of appearing on the HWF recommended PSUs
The Toughpower line is an excellent option. If I recall, they use CWT units, like Antec does. Actually, the 850 is probably a little bit overkill, but it's better to be on the high side rather than the low.
