PSU problem?

[diamount]

Hey guys,

So I bought some hardware off OCUK but opted not to get a PSU since I had one from my last build. Anyway, parts arrive and everything is plugged in. However the fans from all the components (including the PSU) spin for 2-3 seconds, stop and start again for the same amount of time. There is no light from the motherboard.

So do you think the PSU is toast? This is from jump-starting it with a screw driver btw as I haven't yet put the gear into the case.

1. It's a Corsair CX500.

2. Yep, all connected.

3. The motherboard doesn't seem to be turned on as there is no light.

Anyway, the spec is:

powercolor r9 270

intel g328k

gigabyte z97p z97

corsair xms3 dd3 memory 4gb

Thanks for your replies, however I think's obvious the PSU is the one playing up as I looked up the warranty and it's 3 years, around the same amount of time when I purchased it. If not though, I'll be very upset lol.
