A reliable unit for more mid-range builds.

If you've been after a reliable PSU for a reputable manufacturer but you don't necessarily needs oodles of wattage, then this 750W Corsair RM750e may well be a good choice for you. You've got enough power for virtually anything these days apart from the real top-end components, a Cybenetics Gold efficiency rating and it's fully modular for minimal hassle when building, too. Currently, this unit is down to £80 from Amazon, which is the best price it's been so far in 2026 from the big online retailer.

The RM750e is a reliable Cybenetics Gold rated unit, which is is testament to its efficiency, and also provides peace of mind, too. Inside, it also features a 120mm fan with a specially designed fan curve for especially quiet operation. The fact this is also a fully modular PSU also helps for cable management, and to allow for better airflow. Building a PC without a modular power supply can be a bit of a pain, given you'd have to find somewhere to put all the loose cables you aren't using, so a fully modular option keeps things convenient. Its 150x140x86mm dimensions are conventional for ATX power supplies, too, giving you a lot as far as compatibility goes to slot it into a variety of systems.

750W of power gives you enough oomph for running virtually everything, apart from a select few top-tier components, being the recommended minimum specs for AMD's RX 9070 XT and Nvidia's RTX 5070 Ti, which are two of the best GPUs out there at the moment. For older components, Nvidia recommends a 700W minimum for the 4070 Ti Super, while AMD recommends a 700W minimum for the RX 7800 XT, so you've got a little bit of headroom here for a beefy 1440p and 4K-capable system on the latest hardware, or a generation out. This PSU is also fully ATX 3.1 compliant, so to provide enough power for PCIe 5.1, which is handy, while the RM-e units are A-tier rated on the Cultists PSU Tier List (formerly of LTT Forums), if it's any further proof of their reliability.

If you want to grab a capable PSU for powering your PC at a bargain price, this Corsair RM750e deal from Amazon is marvellous.
