Building your own PC is extremely rewarding. Lots of time and effort can go into sourcing all the right parts, making sure they are all compatible with each other, and selecting a colour scheme and aesthetic that makes you proud to show it off to your friends and fellow builders.

You buy your parts, put your new rig together, and hook everything up to your shiny new PSU. Then you see them – the ketchup and mustard cables. Even with tidy cable management or a higher-end PSU that boasts black cables, you can’t help but feel you need a little more. But where do you start?


  • Where can I get cables that will last?
  • What resistance do the cables need to be?
  • What length works best for most builds?
  • Which cables will I need to hook-up my whole build?
  • What on earth is paracord?

At Reaper, we believe in bringing quality PSU extensions to everyone, and simplifying the whole buying process, all without the eye-watering price tags often associated with PSU extensions.

All our extensions come in 30 cm lengths, have thicker cables for fewer gaps and better airflow, are offered in a range of distinctive yet clean colour combinations, and are built to last with a 3-year replacement warranty. So whether you’re a first-time builder or a veteran computer enthusiast, you can always get that next-level look by choosing Reaper.

We are confident in the quality of our goods, and therefore believe you should not experience any hiccups. As such, we offer a 3-year replacement warranty on all our extensions.

Simply let us know about the issue, send the defective goods back to us, and we will send out replacement items as soon as they are received.

The warranty is exercised at our own discretion and thorough testing will be conducted upon receiving returned items.
