however from ur first post "Axle 400W PSU (This is a Genuine PSU which supplies" to me this sounds like a crap PSU - never even heard of Axle and Genius usually make cheap stuff. I personally use Corsair, Seasonic and OCZ (and Coolermaster Active PFC for budget builds). Well if it has a manufacturer code you can tract it down who's the OEM is. refer to this article.
