Seasonic FOCUS GX-1000W 80+ Gold Full Modular ($250-110=$140) [CC] ATL

Great sale price for a reputable PSU maker.

I don't know who would have everything but a power supply for their build ready, but if you were waiting for a deal suitable for mid to highend PCs this is a good one. The power supply is the one component I wouldn't advise on cheaping out on.
