    My PSu is not a Branded PSU but the sticker says MAX OUTPUT 350W ......

    AMD RECOMENDED 400WATT .. how can i run with 350w please explain me?
  6. Its irrelevant if a cheap psu has a low 12v rail. It can still fail no matter the watts.
    Risk your £200 board and chip at your peril. Check the ampage and make.

    In your shop bought pc's before you stuff graphics cards in them, or it will
    ALL END IN TEARS!
  9. 12 Volt rail output 34 amps. Cost £35.
    The psu in a shop bought pc costs about £8 cos there is no power and no protection. When it dies it can destroy your machine. st gen i5 not a new unit, is it? Already tired. Replace or wait for the bang.
