What power supply would need for sli 970's and is my pc compatible?

[jamespg42]

I would like to buy another gtx 970 for sli, however I only have a 500w power supply, so could someone please recommend me a good PSU for around £50-£70? Furthermore I would also like to know if my PC would bottleneck it, I have msi970 gaming mobo and an fx6300 over clocked to 4.5 GHz with capabilities to go to 5GHz.(water cooled with Cooler Master Seidon 120V)

It may bottleneck but probably not enough to be worried about.

You don't need anything more than a 500W PSU so don't worry, I'm running a 970 on a 550W PSU and I was previously running it off of 500W before I upgraded PSUs.

You can always get something like mine: EVGA Supernova G2 550W, although it may be a bit out of your budget.
