Power Supply for Graphics Card PLease

liverpoolrdbest

Hi,

I am buying the 6600GT 128mb graphics card from scan.co.uk. (LINK)

I have a dell dimension 4550 with a power supply of 250w.

For this graphics card, it requires 300w, so will need a new power supply (I think).

Will any say - 400w be compatable with my computer. Any good offers going around please?
Does the graphics card only need to connect to power supply to work.

Many thanks for any help,

Cheers:D

600w or 700w should work, but i recommend about 500w (which is what i have)

500w will be fine. Dabs have some for about £20.

Cheers,

I'm hoping to spend up to £30 inc. postage.

Will any standard supply fit into my machine?

Cheers

It's not the overall power that's so important as the individual current available on each of the voltage lines. For a modern pc with decent graphics card separately powered you need a +12v line of at least 18amps. Also make sure you go for a decent branded one with overload & current protection - cheap power supplies may supposedly have decent power/current ratings, but should they blow then without the protection you can destroy other components as well. Look to spend at least £30 on a reasonable one. Not 'any' but most supplies will fit. Your PC will take a standard ATX supply - new ones have a 24pin connector for the motherboard but have the end 4 pins detachable to fit 20 pin connectors

If you're replacing the power supply on a Dell, I seem to remember that the connections between the power supply and the motherboard are not standard. In other words, if you buy a replacement power supply and connect it up, it will either not work or damage some components.

This may only apply to older pre P4 models - perhaps somebody more knowledgeable than me will be able to help!

TJohn gives good advice. I think 18A is a bare minimum. Ideally you should be fine with 22-26A. It's always well worth spending the extra money and getting a decent one.

TJohn and Wolfman are spot on here - there is a reason that some 450W PSUs are more than twice the price of some 6-700W PSUs its always better to pay the extra as otherwise you rin the risk of not just the PSU failing but it damaging other components. My one to avoid is Qtec.

Any advice for the best / most reliable makes and where to buy from?
