Here's a question that hopefully somebody can answer for me.

The board has a standard 24-pin power plug, 2 8-pin +12v mb plugs, and 2 molex power plugs (ez-plugs).

My power supply, an Ultra X3 1000w, that I was hoping to reuse in this new machine only has 1 8-pin +12v mb plug (and 1 4-pin +12v mb plug).

I just plugged in the single 8-pin +12v and one of the molex plugs (ez-plug) and powered up to make sure I didn't have a DoA board before
starting in on the build....and everything booted up just fine.

However, am I going to run into problems once I start actually stressing the board with use? Do I have to get a different power supply?

[on a side-note: those 8-pin +12v plugs came capped off with a 1/2 size (ie covers 4 of the pins) cover caps. Could/Should I maybe use
the 4-pin +12v plug that the power supply also has on one of these, with the cap covering the other 4 pins?]

Thanks.
