Trying to put together a DH87RL mobo + i5-4570 + gskill 8GB RAM with a old power supply (Thermaltake 430NP). The system does not boot, though the enhanced standby LED next to the ATX power connector on the motherboard is lit. the chassis fan does not run. the hard drives do not spin up.

Am I looking at an incompatible PSU ??

There is nothing about that CPU and PSU which are incompatible.

Is the CPU fan header occupied with a fan? Some mobo's won't allow the system to boot if it doesn't detect a CPU fan.

Barring any possible unconnected cables, it could be a DOA PSU. Looking over newegg reviews, there are quite a few reports of DOA.

The psu is an older one, which was working fine with my previous mobo.
The cpu fan is connected to the fan header. The front panel connector is also connected to the mobo which also worked with the prev mobo.

Is it a doa mobo??

Btw, the fan on the psu does not turn ON either.

Turned out to be a bad PSU. swapped the old one out for a brand new Corsair GS600 and the system works perfectly now.
