Antec Neopower 650w

Hi i've posted a spec of my PC here http://www.tomshardware.co.uk/foru [...] _11_0.html though that has changed a little, I'm now going deff getting het Rampage II Extreme and i'm also sticking in another GTX 275 and running 2x640GB Cavier Blacks in Raid 1, my question is will the Neopower be enough for it all its rated Highly efficient (up to 85%). I know someone very high up in Antec (UK manager) and he said it should be a problem running that system. I've gone to Antecs PSU Caculator and running that system with the CPU clocked at 3.5ghz on a 1.3v will only take 579w. My understanding is that the PSU probaly has another 100w power it could use. I'm hoping he is going to be getting me a 850w Trupower but if he dont would that be enough to run it. I do have a 2nd 650w Neo that could be daisy chained but need advice on that.

Lokk forward to your response's

That's not the power consumption, it's recommended PSU size. You should be fine.

Hehe yeah i know i was taking in to account the overclocked speed about 200w according to the calculator.

Ok got my final list of parts and will give the PSU a try, parts will be ordered on payday hope to be with me the week after.
