@burnin what would you reccomend as an on the cheap but quality psu sub 75$ pref?
Edit forgot to add only plan on running a single btb XX at 431/450
Im not burnin, but Xbox 360 PSUs works very well for 1-2 boards.
All you have to do is cut the cord, wire +5V SB and PWR_ENABLE together for "always on" mode and use the three yellow (+12V) and three black (GND) cables to power your boards.
I ran 2x20 an 1x10 with an old Xbox 360 PSU (Xeon/Zephyr version with 203W) just fine, but only up to 400 Mhz.
The nice thing about this is that you can find old 360 PSUs on ebay for less than $10 and they deliver very clean power.
