Dear All,

I have a old PC power supply. Now, I want to re-use it to run serval fans for aquirum tank. Please suggest how to modify the power supply to meet the usage.

Dear green green:
Can u see a largest plug at the transformer, you can see only one green cable in the plug (around third hole of the plug) and a any black cable in same plug (I choice fourth hole), use a 100 Ohms Resistant (Can buy at SSP electronic shop , $1 per 1) short it. I mean one side at green and one side at black. Switch on the power, OK! (If really cann't find resistant, only short two cable is OK, But easy to damage the transformer.)

Dear Green green:
Do you know how to identify 12V and 5V cable ? And basic electricity wiring L & N, in parallel & in series. If no, i suggest you shouldn't try.

12V: 黃色係正極, 黑色係負極
5V: 紅色係正極, 黑色負極

唔識唔好亂駁，駁錯著火好危險
