Hi guys - thank you for taking the time to read this and to hopefully answer my query.
My current graphics card is starting to play up (fan noisy) and I would like to replace it but have a few queries regarding what I should be looking for in a graphics card to suit my system.
After doing a little bit of research the main query I have is picking a card which will work with my current PSU as mine is only 250w. It may just be me being thick

but on all of the card spec's I've looked at none of them give a power requirement.
If anyone could give me a few pointers or recommend a card I would be most grateful.
Many thanks
Karlos
