I've tried two Seasonic M12 500 watt PSU's and neither will fire up when installed to my VFN4 mobo. Doing the 4 to 5 pin test to get the PSU fan spinning works, but when installed on the motherboard, nothing at all happens when the comp is turned on. I have ruled out any problems with the comp's on/off switch.
My question is a long shot:
Is there anyone here using a Seasonic PSU and a Chaintech mobo? And if so exactly what models?
