Now is a great time to upgrade your PC’s power supply, as Amazon is currently offering several modular Corsair PSU deals at their lowest ever prices. If you buy your new power supply before the end of 2025, you’ll be able to save 29% on the price of a Corsair RM750e, bringing it down to just £75.05. You can even save big on an RM1000e, which has enough juice to power an RTX 5090, and now costs just £109.99.

“Corsair RMe Series fully modular low-Noise Power Supplies include a dedicated 12V-2×6 GPU power cable, ATX 3.1 certification and PCIe 5.1 compliance, and Cybenetics Gold rated efficiency for a quiet, reliable build.” – Corsair
That price for the RM750e is the lowest we’ve ever seen on Amazon, and while the retailer lists it as being reduced from £104.99, it spent several months of the year priced even higher at £114.99. You’d normally expect to get a basic PSU with captive or semi-modular cables at this price, but the RM750e has a fully-modular set of wires. That makes it easy to cut down cable clutter, as you only need to hook up the cables you need for your system.
Crucially, the set includes a dedicated 12V-2×6 cable with a native 16-pin connector, ready for the latest GPUs, meaning you don’t need to use a messy multi-socket adaptor or extension cable. With ATX 3.1 certification, as well as PCIe 5.1 compliance, this PSU meets all the latest standards as well. Meanwhile, its Cybenetics Gold rating ensures overall efficiency of 87-89%.

If you need more power, perhaps if you’re building a rig with a top-notch GPU, then now is also the time to pounce on a 1,000W PSU. Corsair’s RM1000e is currently going for just £109.99, which is an amazing price for a fully-modular 1,000W PSU with this spec.
All these power supplies are also compact, measuring just 140 x 150 x 86mm. This means you should easily be able to squeeze one into your case, unless it’s a tiny SFF model, but it’s also worth noting that they only have 120mm fans, rather than the 140mm spinners found on larger PSUs. As such, their noise levels tend to be louder at heavy loads, but not disastrously so.
At these prices, you really can’t complain, though – £75 is a bargain for a modular 750W PSU with Cybenetics Gold certification, as well as a dedicated 12V-2×6 cable. You’ll need to be really quick, though, as these deals will expire as the clock strikes Midnight for New Year’s Day. Get in quick if you want to grab yourself one.
