Thank you so much for a reply, when I say cpu is over clocked I mean of course that I have the alienware command center software cpu overclock on from default to a setting of 2. Alienware Command Center has a stable over clock set by them where you can turn it on 1 or 2. I do think it could be manually set higher. Its sold as a stable over clocking tool or setting.
If I cant replace to psu by buying my own brand then I guess I am forced to buy the dell 850w. Its about 250$ for 850w which I thought was high. But its Dell we are talking about. I know you say not to trust power calculators but they all say about 1250w and I have a 850w. You guys are saying I should be ok with a 850w? I just realized this psu has a self tester button on the back. I guess I will push that when systems off and or try to reseat some stuff.
I just thought I could buy a name brand psu and potentially use it for a future build. If I buy another Dell then this PC is all its good for. I dont like Alienware no more.. Thanks again.
