more than a year is no age for a PSU
the CXM BadActor listed (the updated version with grey lettering) is halfway decent and should get the job done if it isn't stressed enough. don't expect 10 years use from it but it's nice.
alternatively a Seasonic S12II, a XFX TS Bronze / Core Edition / Pro Edition / Bronze Fully wired
depending on your location they are usually pretty cheap or are at least reasonably priced
