buckstar · May 7, 2012, 12:31 PM

hi just finished my new build and have no power from my psu. i have a green light on my motherboard but thats all i have. all connections are installed correctly. my case fans are not even spinning when connected to the psu. any ideas on this or is my psu dead? it's brand new tho.

sounds like you got a bad PSU. there is a trick to check it, give me a minute and I'll get you the details of that trick

Crap Daddy · May 7, 2012, 12:37 PM

Please list your specs.

Have you connected your fans to the headers on the mobo or directly from the PSU? CPU fan is spinning? Unplug your 24 pin and the 8 pin CPU and plug them again - I think they have to make a click - and try again

buckstar · May 7, 2012, 01:05 PM

will try but need to find a paper clip 1st ty

buckstar · May 7, 2012, 02:56 PM

ok so i did the paper clip thing and the psu and fan worked, so im just wondering if it might be the motherboard or ive not connected it up right? gonna check if i have cnnected the case switchs correctly could this be causing it not to work?

if you get a reaction of some kind from your computer when you push the power button, I don't think you hooked up the switches right. My next guess would be a bad motherboard.

problem solved. it was the 8 pin power connector that clips into the mother board . i split it so its 4 pin and now everything is working fans and cpu etc. just not booting into windows 7 at the mo so thats my next step thanks for your kind help it's much appreciated

Odd, so you didn't have the 4 pin hooked
ASUS F1A75-M PRO FM1 AMD A75 (Hudson D3) HDMI SATA...

Is it that board? It shouldn't have an issue running an 8 pin.... Hmmmm

buckstar · May 7, 2012, 04:03 PM

yes very strange

Yes? No? If you didn't have any Aux power for cpu that was the culprit.

buckstar · May 7, 2012, 04:49 PM

in my psu manual it says. note: 8 pin is mainly for servers .

if i run the 8 pin would it make any difference to using 4 pin?

If you overclock it may help some.

Most high end motherboards have 8 pin CPU connector, which should be used unless stated otherwise
