It should be fine, believe it or not, that particular quad doesn't use much more power than your single core chip if at all.
thank a lot!!! if i would had to buy new psu i would be digging empty pockets
In pure wattage terms, your PSU is fully capable to handle even much stronger quads with a good amount of overclocking applied..
