PSU Guru Needed!!! Help!!!

post #1 of 10
Thread Starter 
PSU just kicked the bucket but I have backup (a couple years old) and trying to find out if it can handle my current setup (see rig).

750w Delta PSU (Backup psu):
+5V / 30A
+3.3V / 30A
+12V1 / 18A
+12V2 / 18A
+12V3 / 18A
+12V4 / 18A

Total +12DVC outputs shall not exceed 732W

This psu has (2) 6pin cables for graphic card. I can plug the (2) 6pin cables to the dual 6pin-to-single 8pin adapter and use a dual molex-to-6pin adapter. Zotac GTX 480 Amp needs a 6pin + 8pin w/minimum 12V current rating of 38A.

Can this psu handle the job without the GTS 450?

Yes it can.

EDIT: maybe I was wrong

The only thing I question is the 18Amps per rail for the GTX480. That is only 216 watts, will that be enough under full load?

Is this simply saying that I will have a total of 36A from the (2) 6pin-to-single 8pin going to the 480? As for the dual molex-to-single 6pin connected to the 480, how do you calculate the total Amps for that connection?
post #10 of 10
Yes it can.

The 18A per rail thing isn't a problem either. Load balancing is done automatically.
