Best Budget Power Supplies UK 2026

About this band

We have reviewed 30 budget power supplies, and these are the three worth knowing about first. The top-rated pick is the Cooler Master MWE 850 Gold V2 Fully Modular PSU (UK Plug) (rated 8.5/10): Solid, efficient and sensibly built, but the missing 12VHPWR connector will frustrate… In second place, the Fractal Design Core 1100 (rated 8.5/10): Brilliant airflow and premium looks for the price, but PSU and GPU… Rounding out the top three, the Thermaltake Dr. Power III | Power Supply Tester (rated 8.5/10): A solid first-line fault finder, but useless for load or ripple testing. Each of these is worth a closer look before you buy, and the full list below covers every option we rate in this band.
