Hmm according to the calculator my system needs 424watts
I have an 850 watt psu
so a nice solid 200% for me.
Two years later, and I'm now ordering a new powersupply. SIX YEARS with my old thermaltake power supply and it has now degraded so far it can't even handle a system that requires UNDER 250w (with a HD7750, and underclocking/volting my 940be). It probably only runs at 200w or less because i'm using the onboard video. System will HARDLOCK (screen shuts off, computer crashes, occasionally powers down completely)
so now I'm putting in a corsair cx600m, which puts me at 316w, or 189% once I put my clocks back to where they should be and drop in my overclocked HD7850
