Duke79 Posted August 23, 2006 Share Posted August 23, 2006 Hi PowerGuy -- ZipZoomFly finally got the HX620w in stock. So I placed my order immediately and received the Power Supply via FedEx. I couldn't wait to plug it in and see that fan turning so I'd know it would be ready for the new computer I am building with all the components slowly gathering on my workbench. I plugged the power supply into the wall socket and nothing. Nada. I flipped the switch on the HX620w a couple times ... no change. I assume the power supply can be powered up without being connected to a motherboard ... right? The fan should be turning and I should either feel or hear a slight humming from the power supply? I'm getting nothing. So did I get a DOA power supply? Not a good feeling for a first time Corsair purchase ... Any suggestions on troubleshooting?

Yellowbeard Posted August 23, 2006 Share Posted August 23, 2006 You must plug the PSU into the MOBO and then switch the system on before the PSU or the fan will work. You will not get any response switching the PSU on with no connection to the MOBO. Mike. Link to comment Share on other sites More sharing options...
bcwang Posted August 23, 2006 Share Posted August 23, 2006 Yeah, don't worry about it being DOA in your situation, it isn't supposed to do anything if nothing is plugged in. You need to get it in a system connected up to a motherboard first, or you can short the green wire to a black wire with a paperclip to get it to turn on if not in a system.
