Sparda Posted June 9, 2008 Share Posted June 9, 2008 So I got a new power supply for my gaming computer as the old one was no longer big enough (480W) to go with my new graphics card and that work fine. I thought I would put my old PSU in the computer I leave on all the time, my tests show that the old PSU uses about 0.6A of power while the 480W PSU uses 0.4A. However, with the new PSU it is unable to boot. It will start booting then restart. It still works with the old less efficient power supply. The only reason I can see for this is that the power consumption minimum i not been reached for the new PSU. It used to run 4 HDs, 2 DVD drives, graphics card (PCIe) and a Asus Crosshair mobo with a Athlon 6000. It's now been reduced to a 2.4GHz P4, 2 HD's and a CD drive. It also has a 24pin mobo connector but I only plugged in the first 20. Some thing of interest: It is a modular PSU, so you only connect to the PSu what you need, the computer only needs three cables, the two that are permanently attached (mother board connectors) and one cable that has 3 four pin molexes for the drives. Any ideas? I thought about attaching some resisters to PSU internal connectors to attempt to bring the PSU up to its minimum power consumption level, but I'm not sure.
