    With your config 500W should be plenty. It's worth trying even if it's just to eliminate a variable.

    I know the calc tools on most sites are there just to get you to buy a bigger PS, but 500w for a quad core with 8gb of ram and 6 hard drives?

    I'm not saying swap the 500W and use it because your other is to big. However 99% of people grossly over estimate how much power their PC uses. In 2d full load I'd be surprised if your PC would be using more than 250-300W with all hard drives transferring data. In game, you mightreach 400-420W.

    The rig in my sig, with an overclock can be powered by a 400W OCZ. The same system with a Q8200 quad core is also fine on the 400W. It's probably on the edge when the GFX card is fully loaded, but it can handle full 2D load all day.

    Graphics cards are the biggest consideration when choosing PSU capacity. My mid sized capacity HX750 could happily run two GTX 285's along with everything else and still have a little in reserve. It may just stretch to Quad Crossfire 4870's, but likely the fan would be pretty loud at that kind of load.

    Well if it is the PS I guess I'm not going to be happy that I already sent in the rebate for the PS, maybe I could have saved myself $100. Newegg suggested 820w, I was going to go with the 650 or 750, but I figured the 850 was only $10 more. Oh well maybe I should have just kept the 500 I had and only replaced it if the system started to hiccup.

Also increase MCH Core to 1.200V and set VDIMM to the correct value if it's not already. If on Auto, set it manually to be sure. Also set the 2.40B System Memory Multiplier manually to make sure the RAM is at DDR-800.
    Ok these changes have been made, first boot was good, I'll how it goes over the next day or two.

    Question: I guess I can see setting 5 5 5 18 manually, though that is what auto said it was doing. But are the other setting doing? And I did not see VDIMM? Though the memory says 800 800 on auto (if I'm actually looking in the correct place that is).

    Excellent.

    It's always best IMO to get rid of as many auto settings as possible. This means you're able to tune performance to what actually works best rather than what the board thinks. It's also been known to happen that the values the BIOS says it's setting don't actually match what is really set. Rare but possible. Advanced RAM timings are 99% of the time stable on auto (tRead may need a tweak) and the main benefit of setting these is to squeeze a drop or two more performance out of the system.

    VDIMM is another name for DRAM Voltage. As long as you have it set to the spec of your RAM (usually stated on the packaging or the sticker on the module) then you have it correct.

    Let us know how you get on stability wise. You may want to run a program called Intel Burn Test to roughly verify stability. Set it for 5 runs on maximum stress and in a few minutes it can tell you if you are in the realms of stability. Running Prime95 over night on "Blend" for a min of 8 hours would be a more thorough test IMO. 8 hours should be fine for general purpose stability and gaming etc. Only do more if you're an overclocking enthusiast or do alot of distributed computing, like Folding@Home, where it's crucial the data you send is 100%.

    Pass at standard and Maximum. But running has not been the issue, only booting.

    Short lived success, still won't boot first time.

    I suggested the stress tests because although you may be able to use the machine fine, there are certain levels of instability that may not show up until for example 14 hours of Prime95. This may be the same issue that also prevents a system from booting first time.

    Usual suspects are auto settings (which are detected each boot). Things like RAM timing (inc tRead) are the most likely.

    Psycho101,

    Thanks for the help, but in the end this board is going back. I just don't have any more time to spend figuring out why something doesn't work (not to mention my window for return means this needs to be in the mail by tuesday/wednesday). And while since it is fine once it boots I have a wedding to finish with, I've spent too much time on this already.
