K8N riddle

Hi,

I have some problem I can't solve: a brandnew K8N motherboard, with
Sempron CPU and 500MB RAM, and a brandnew 300W PSU. At my place, the
onboard powerled burns. When I power-on the system, the CPU-fan runs for
a few seconds, then stops. The PSU connected to an old PentiumIII system
shows no problem: it just boots as it should. I took the K8N and PSU to
the retailer, had it connected just the way I did, and it runs without a
problem.

If anyone has/had a similar experience and solved it, please let me know
(and be so kind to tell me the solution )

Thank you.

Huub

There is a second power connector on the board that you must plug into
with a special connector from your power supply. It is a square, 4-pin
socket. Only newer power supplies have them. You can buy an adapter
that goes from one of the disk drive connectors to this connector for
around $10. If this message seems new to you, then that's your problem.
I had the same problem until I read the manual.

Seems to me like a shortcut when applying the board to you case. Check if
there are screws or spacers that touch the rear of the board. Likely a
spacer that is screwed in the mainboard plate of the case is at a position
where is no hole in the board to put in a screw. If this is the fact you
will shortcut the board. Check carefully. In some trays there is just a
little space between two screw. If you select the wrong one bang.

Alas, all necessary power connectors have been plugged. The square plug
indeed was the case the very first time.

To add to this: I connected the 350W PSU from another system to the K8N
and that boots the K8N as it should. So why doesn't the 300W PSU do that
while it should? Now I intend to switch the PSU's within a few days.

I had a similar issue years ago with a 486... long story. The mains voltage
at home was marginally lower, the PSU was struggling with the lower voltage
and havoc resulted.
