Does anybody have a Lanparty nf3 250 MOBO running on just a 400W power supply? Preferrably with an AMD 64 3400? I''ve already purchased the parts but dont have everything in yet so I haven't tried it out yet. I just found out the the board suggests a 520W PS!!! I dont plan on overclocking so I'm hoping the 400W won't give me trouble! Anybody have these parts on a working PC?
