I am using the Thermaltake ToughPower 700W PSU

My System spec is

C2D E6400
2GB CORSAIR
ABIT FATAL1TY FP-IN9 SLI
NVIDIA 7800GT 256MB
200GB SEAGATE SATA
20X LITE-ON IDE DVDRW


If I connect everything ( except the Seagate ), system boots up fine. But, as soon as I connect the Seagate and then switch ON the System, PSU shuts off within 2 secs.




Help would be appreciated

If the system shuts off it is likely you have a short. Try remounting the hard drive in different bay. You might try a different SATA and power cable.

Btw, the fan in the PSU never spinned.

Is that how it's supposed to be?

I mean, it spins only under Load?

Some ps have a built in thermostat; it's possible the fan won't spin until your system is warmed up. My old socket 754 fan only spun about half the time.

I opened one up. The Yate Loon fan inside was not FIRMLY plugged into the PCB.

Plugged it in and it's all well now

Works even with the SATA Hard drive.

what fan? the fan inside the psu?

Yup

so i guess you remove the warranty stick, good luck to get it service.
