My GPU needs no power cables just plug in the PCI and good to go. (Asus Geforce GT 640 2GB) Runs every latest game to date that I have tried (Gta 3/4/5, Fallout 3/4 and many more with no problems. Only a Quad core 2.4 GHz Processor but runs great as well. Took 10 mins to fit this new PSU today and no problems given it only cost £37.00 new + £7 shipping! Powered on straight away and runs sweet.
Opened my old PSU 2 days ago and not joking here the whole unit was full to the brim with dust and muck like a vacuum cleaner would be after cleaning all the carpets. Lucky it never went on fire like my old PC did...TWICE!. And yes I did try the old PSU after cleaning it out but same SQUEALING PIG NOISE and shut down on any power load. Took 2 hours to fire it up last week!
Your old computer sound ancient Noodles but surprised it was a 2.4 processor given the age of it. You just kicked mine in the balls there!
