I've just bought a pre overclockd bundle comprising Intel Core i5 4690K clocked & tested to 4.6Ghz, Asus Z97-A board, 2x 4GB Corsair Vengance Pro 2133MHz

I'm using the following with it:

OCZ GSX 600w PSU
2x Nvidia GTS 8800 SLI (old, I know!)
1x 128GB Sandisc SSD
1x 64GB Crucial SSD
2x DVD-RW
6x Case fans

It won't power up at all. None of the board led's are on & only a couple of case fans work. There are no audible warnings. Just nothing.

I'm confident it's all been put together ok & it came with the memory, cpu & fan fitted. All well packaged. I've built several systems before so I'm sure it's all correctly fitted.

When I switch it on the psu illuminated fan light flickers as if it's struggling to power up. I removed the SLI cards and the PSU fan light stayed on but dimmed & brightened constantly.

Is it my psu that's too weak to run this system? It's not faulty as it was ok with my existing rig.

Any help would be very welcome - thanks!

Many thanks SR-71 & Tradesman for your replies. The PSU was top of my list of likely problems so I'm away to order a new one. Thanks guys.
