ATX2 psu

Hi guys.

Im working on a atx2 psu so i can use it to power a prusa mendel with a hotbed.

Its a codegen 500w psu.

i have soldered a 10ohms/10w resistor to the +5 rail.

Doing that i have 11.84 v on the +12 rail.

Is that ok or should i add another load to +5 to i can raise the +12v value?

Also, this psu have sense wires for 3v and 5v. I soldered those sense wires to the correspondant +v but the psu didnt worked. I cutted both and it worked.
Havent tried about leaving only +3sb on. Do i need to solder those sense wires or i can work around it without conecting them?

Thanks!

All you should need to do is connect the green wire in the 20 or 24-pin motherboard connector to any black wire, and then possibly the resistor across 5 V. No other wires should need to be connected for the power supply to turn on.

11.84 V is fine as long as it does not drop much when loaded by your printer.
