After Market Power Cord

Has anyone bought a aftermarket power cable for there PC.If so which one and did it make any difference ?

I have not done that on my imacs, but if you need custom power cables, check out Cullen Cables. Very good quality cables at fair prices. He’s made three power cables for my audio components, including one that needed a special narrow profile plug to fit in the back of my PS Audio P5.

Okay thanks.I like the PS Audio P5 have two of them in my system.

I use WireWorld Silver Electra 7 throughout my system. A bit pricey, but I believe they improve every component they are added to, including my PS Audio P10.
