Startup issue, suspect the psu

I've recently decided to rebuild a pc I built around 6 years ago, so went ahead and purchased a new mobo, processor, memory and graphics card, thinking that the psu I had would be fine.

However with everything put together, when I power up, all the fans spin, the mobo led and gpu led light up, but it doesn't boot, just a black screen and no beeps. The monitor just says no signal.

My specs specs are:

Motherboard - MSI 970 GAMING AMD 970 (SOCKET AM3+) DDR3 ATX MOTHERBOARD

Processor - AMD PILEDRIVER FX-6 SIX CORE 6300 BLACK EDITION 3.50GHZ (SOCKET AM3+)

Raijintek Ereboss cooler

Memory - CORSAIR Vengeance CML8GX3M2A1600C9 DDR3 PC Memory - 8 GB DIMM RAM

PSU - OCZ OCZ600MXSP-UK ModXStream Pro 600W ATX Power Supply

Now being the only part I didn't change, I'm wondering if the psu is up to the job of powering the new parts?

Any advice would be greatly appreciated.

Do you have a speaker connected on the motherboard?

Couple of things to check, all power connections connected the motherboard including the 4 or 8 pin for CPU power - the same goes for the GPU.

Check the locations of memory as some motherboards are fussy which slots are used.

Also try a CMOS reset as this sometimes help.

I would be surprised it's your PSU, as in terms of power this more than enough for your system, but does not rule out being faulty. Can you test any components I another system?

I thought I had a case speaker in my case, seems I don't, so I'll have to grab one today from a spare pc at work, that might help diagnose things.

The 8pin power connection for the cpu is in place, I tried the paper clip test on the larger motherboard connector and it powered up a case fan, could the 8pin still be faulty. Do you test the other connection too?

I'll try resetting the cmos this evening, would this make a difference if its never been powered up before?

The only reason I thought psu is because everything else is new and it's been sat for around 3 years unused. Would a faulty hard drive cause any issues?
