I apologize if this has already been covered but I haven’t seen it.

Does anyone know the power usage of the HD 4850? I just put together a new rig (long over due) should be arriving tomorrow but I’m starting to become concerned I’ve short changed myself on the PSU.

Here are the specs:

NZXT Tempest SC-NT-TEM-B Case.
Gigabyte GA-X48-DS4
(2) HD 4850 X-Fire
4 Gigs DDR2 1066
E8400
(3) Hitachi 7200RPM SATA Drives
LG DVD burner

There are 5 fans on the case, LED lights, and of course an aftermarket cooler for the CPU. Plan on a moderate OC on the E8400 (3.6ish).

The Power supply I thought would run all these goodies: Corsair CMPSU-750TX, http://www.corsairmicro.com/products/tx.aspx

Now I’m seeing 200+ Watts for the HD 4850 if that’s the case I’m afraid this might really push my PSU. Any thoughts?

i think that 750watt is wayyy more than enough for that!!!
