A PSU will not work on it's own - it's the motherboard that switches it on and off.

Five possibilities - PSU, Motherboard (about 48% each), case switch (almost never), some other component in the system (rare), mains supply/cable (rare)

Disconnect all drives, RAM, plug-in cards - see what happens.

have done that already & tried 3 power leads, still no good?

If it's "newish" then it presumably will still be under guarantee. If so, obtain a replacement.

have you tried another wall socket, I remember one of my house wall sockets was once dodgy.

Ive experienced something very similar recently triflesterms click here
Im just waiting for another cpu to arrive and try that...but it seems like the mobo has died.


triflesterms..if you read through my prevoius thread (link above)..i tested my psu..probably not the best way..but did give the answer...i did have power going to the mobo.

Hope this helps

Check:
plug wiring (unless moulded on)
Plug fuse (3A)
Wall Socket powers another appliance. (house wiring not adrift / main fuse blown)
try new lead.

switch at rear of PSU (if fitted)

front panel switch

PSU recieves signal from mobo

Dont know how you tried to test PSU on its own.
It needs a load connected or you will get no readings if you used a meter.

Ive tried all of the above with no success,is there another way to test signal from mobo? im not online at home,i havent tested psu on its own properly, if the psu is ok, what else could it be?


Thanx
