0PSU LogoThe perfect HTPC power supply 2020?

Published by & filed under Misc Hardware. Last updated .

I recently got a new GPU for my HTPC which required a replace­ment power sup­ply as the old one was­n’t suit­able for power­ing a GPU with an 8 pin PCIe power cable.

0PSU LogoEfficient PSU Upgrades: HuntKey Jumper update
