I seem to have a problem. I purchased a Coolmax 700w PSU recently from ebay to replace a defective PSU in my system. Almost immediately I noticed a problem. Now my system has no sound. I checked all kinds of stuff. Thought I shorted something out. Nope..
Then I remembered that my system, MSI MS-9620 (K8N Master2-FAR) requires -5v for the sound chip to function. This PSU has no -5v. Is there a way to modify this PSU to produce the -5v that I require?
The PSU model is ZU-700B

Thanks
