About this band

We have reviewed 31 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… In second place, the Thermaltake Dr. Power III | Power Supply Tester (rated 8.5/10): A well-specified PSU tester with genuine ATX 3.1 and 12+4-pin… Rounding out the top three, the CORSAIR CX550 80 PLUS Bronze Non Modular Low-Noise ATX 55... (rated 8.0/10): A genuinely solid budget PSU that delivers reliable 550W continuous… Each of these is worth a closer look before you buy, and the full list below covers every option we rate in this band.
