A few people say a 450watt is enough but i'm not sure as my PC is overclocked. Currently running at 4.2gz

case may need replacing( max budget £50 )

Hi

 

ATI HD5770

 

This has the biggest influence in the selection of the PSU.

The system specs associated with this card suggest 450Watt PSU minimum.

I would suggest that you should look at 500 Watt minimum.

 

You also need to consider if you intend to upgrade the Video Card at some point.

If so then consider 600W or more.

It depends on the choice of Video Card.

Thank you, not looking to upgrade for a while, will buy a 550 PSU
