Hi there. I'm holding off doing a PC build until June/July for AM2 reasons. However, i need a new PSU and case. The PSU(QTEC) has become noisier and maybe on it's way out. The case I can't stand, some cheap rubbish. So I'm looking at Li Lian PC7+ and Tagan 530W Easycon SLi Compliant Modular Silent PSU. However, will these be ok for an ASROCK K78SX mobo and AGP FX5900 XT. Thanks. Great forum by the way.
