Would I need to replace the PSU

Solution
It doesn't specify what the power supply in the system is, but I doubt its of any good. Typically you would want something from the likes of Corsair/Seasonic/XFX/Silverstone and Antec, and a few other brands. A CX430 from Corsair would do you well -- its a decent entry level power supply and is somewhat decent for the price.
