Should you be on the hunt for a new power supply, there's a cracking promotion currently underway over at Amazon where you can save up to 28 percent on the Corsair CXM series. Ranging from 430W all the way up to 850W, there's ample choice here for a budget, overclocked or enthusiast deployment. Corsairs CX850M, which is likely overkill for many PCs out there, is only £84.99, down from £114.99.
These PSUs are semi-modular and 80 Plus Bronze certified. While anywhere up to £100 could be considered a steep investment for a single component, one should never cut costs and corners when it comes to the power supply. This is the unit that will regulate and provide juice to all your installed components and we don't have to go into detail as to what could happen with a less-than-reliable unit.
