Used Power Supplies for Sale - UK Buying Guide

Browse used power supplies from verified UK sellers. Find fully modular, semi-modular, and standard PSUs from trusted brands. A reliable PSU is the backbone of any PC build, and Koukan makes it easy to find quality units at lower prices with buyer protection included.

When buying a used PSU, prioritise units from reputable brands with 80+ efficiency ratings (Bronze, Gold, Platinum). Check that the wattage meets your system requirements with some headroom. Modular PSUs are easier to work with for cable management. Ask the seller about the unit's age and whether it has exhibited any coil whine or fan noise. Avoid PSUs from unknown brands, even at very low prices, as a failing PSU can damage other components.

Frequently Asked Questions

Is it safe to buy a used power supply?▼

Buying a used PSU from a reputable brand is generally safe. Look for units with 80+ efficiency ratings and check seller reviews. Avoid units that are more than 5-7 years old, as capacitors can degrade over time. On Koukan, buyer protection covers you if the PSU does not perform as described.

How much wattage do I need for my PC?▼

A typical gaming PC with a mid-range GPU needs 550-650W. High-end builds with RTX 4080/4090 cards may need 850W or more. Use an online PSU calculator with your specific components for an accurate recommendation, and add 100-150W headroom.
