Dave,
I don't recall the tdp of that cpu, however likely that your pc only draws 300 - 400 watts max, max!

How mush was the ps, where did you buy it, who is the manufacturer and model number?

If one assumes that your ps is a quality/reliable manufacturer one it should not be a limiting factor. However most ps that the average joe buys at best buy and the like are junk if they are priced under $100+ FOR THAT WATTAGE - PS are not created equal, of significant importance is the actual manufacturer and the reliability, voltage control of the ps.

Never cheep on the ps, and do the research before you buy.

Others may differ, but my recommendation without further info on your ps, is that >> if << you cannot drop a quad in your existing mobo, you would need a new mobo. Never just replace mobo, i always recommend reinstall of os.
