Thank you very much for your reply.
I purchased the barebone bundle and that came installed with 300W power supply which does not have a connection to the graphics card that I want to use.
I have already got a CORSAIR 600W PSU but the cables are too long so I need a power supply thaT HAS SHORT CABLES BUT WITH A CONNECTION TO THE GRAPHICS CARD.
They have installed a Gigabyte motherboard and have sent its motherboard manual. The fans are noisy and i wish to replace them.
