Question about Computers & Internet
I just purchased a new PSU (Cooler Master 1000w Silent Pro M) and have run into a problem. After I installed the PSU my HP Pavillion Elite with a MSI MS-7548 (Aspen) mobo will not boot. The system fan will spin, the CPU fan spins for about a second then stops and the PC will not start. If I put the PSU in a another computer it boots up, if I put the old power supply back in this computer it boots up. Is this new PSU not compatible with this motherboard? Is there some jumper or setting on the mobo to fix this?
So you're using the same CPU 4+4 Pin x2 power cable on both rigs?
(One of them)
Yes, I see it's a modular cable design, and the CPU 4+4 Pin x2 power cable, can be used as a single 4-pin ATX +12 Volt power cable,
ALL Yellow wires are 12 Volt (DC) wires.
ALL Black wires are Ground wires.
ALL 12 Volt wires go to ONE single 12 Volt power rail, in the Power Supply, BUT; there is nothing saying an individual Yellow wire may be bad.
This is why I wondered if you are using the SAME power cable CONNECTOR. Same power cable.
Then suggest it has something to do with the Active PFC circuit.
Not aware of any setting to change in BIOS Setup utility - Power.
BUT, I do not know everything! lol!
IMHO there is no reason it will not work, unless as said; something to do with the Active PFC circuit.
From here let's hope someone who really knows what is going on, will post.
