I wouldn't recommend to use that PSU without a fan running, seriously, buy a new PSU.

the psu has a fan but when i power on it did not start, so maybe the psu is defective?

It's basically a same thing. Everything connected correctly? I just meant that, if your PSU don't have cooling, there's a possibility that it might blow up.

Please post with some decency, ie: use descriptive thread titles and good grammar/spelling.

From looking at your opening post I assume that you haven't actually managed to get the computer to POST. If when pressing the power button the computer doesn't power on then it is likely that you didn't connect the power button wire to the correct jumper on the motherboard.

Why you are asking, if you already know that the PSU is bad?

Check all your connections to the motherboard.Make sure your cmos jumper is in the correct position.I had that happen to me when I put my new rig together.

Without that jumper, it won't even startup. Probably the PSU is just dead, what is more likely.

Provided the 5v and 12v power cables of the motherboard are connected, the power LED's on the PCB of the motherboard will still light up.

As previously stated, make sure the wire leading from the power button on the system chassis is attached to the correct jumpers on the motherboard.
