Just built a new system - as below - and works beautifully, except when under extreme load with Supreme Commander / Doom 3 / (occasionally) UT3. The power suddenly switches off with no warning, usually right in the middle of some intense gameplay. My PSU is rated at 600W (Jeantech JN120F). I've looked at a few power requirement calculators - the one on the nVidia site is very easy to use. It estimates 950W (!!!) minimum requirement. Now I know these things tend to really overestimate the power requirements but it's got me thinking that the PSU is the problem. What do you guys think? (The rig is not overclocked)
