I know I have posted this in the wrong place -_- Mod please move this thread to where it belongs please I am planning to make my own extension cables for my psu and I just need to know what is the wire used in the middle and where can I get it in the uk? Thanks
The middle wire inside the cable, yellow and green? Or the cable between the PSU and the plug socket?
You're looking for the metric equivalent of 18AWG of 24/0.2 (it's actually a narrower diameter but still within specification). Maplins sell it although it's overpriced but handy for small quantities. I use Rapid 01-1100 and this 01-1145. It is 2.3mm in diameter so 'trains' better when sleeved. If you want slightly thinner insulation then Farnells White and Black at 2.05mm thick are good.
