My new build fires up for a second, fans come on, LED's come on, but dies a moment later.

It was fine when I assembled it externally.

Any idea where I should start with troubleshooting?

Case: NZXT Phantom 410
MB: MSI Z87-G45 Gaming
CPU: Intel Core i5-4670K, stock cooler
PSU: Corsair TX650
GPU: MSI Geforce GTX 670 Power Edition
RAM: 2x4GB Kingston HyperX
SSD: 120GB Sandisk Ultra Plus
HDD: 1TB Seagate Barracuda

What do you mean by CPU fan backplate? (All I have is the stock Intel fan)

Nothing wrong with standoffs. I've taken the whole lot out to reproduce the external build where it worked before.

It didn't work.

I assume I've damaged one of my components fatally.

Update
Found the reason, forgot to plug in the CPU power cable :sarcastic:

Now to put it all back in again!
