I need advise on purchasing a power supply unit for my Dell Studio 540.
I bought an ATI Radeon HD5850 graphics card and when i went to install it the Dell power supply is boxed in and has no leads to attach for power to go to the graphics card. I found this odd as there were slots in the motherboard for the graphics card to fit (PCI - Express).
My PC also has 6 usb ports, one of which is expanded using a usb hub which has its own power source.
Could you advise me on the appropriate power supply to get as i would be worried that i would pick one which is incompatible. I have been advised to get a 600w power supply. I dont mind spending a bit if it will improve the running of my computer also.
