A capable PSU for a smaller form factor build.

Small form factor PC parts can come at a premium, such is the power of smaller components, although it is possible to snag them at a discount if you're happy to shop around. For instance, this 850W SFX Cooler Master option is down to £85 from Stocs UK's eBay store with code HAPPYPAYDAY15. That's quite a far cry from its £100 list price, and the £140-£150 this PSU is going for elsewhere.

This is a reliable 80+ Gold rated unit, which is is testament to its efficiency, and also provides peace of mind, too. 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, especially in a smaller form factor case.

850W of power is enough for running even some of the beefiest components available, with it actually being above the recommended minimum wattage of 750W for AMD's top RX 9070 XT. Nvidia officially recommends an 850W unit for the RTX 5080, while it's above the minimum for the 5070 Ti. Of course, everything underneath that from both Nvidia and AMD will be more than adequate for this wattage - you've just got to make sure the card you'd like to use will fit in the case you've chosen!

What's also interesting here is that this Cooler Master option also comes with a bracket so it can fit in even bigger cases. That is, ones that support anything up to an oversized E-ATX motherboard, so if you decide that the small form factor life isn't for you down the line, and you want to retain your PSU, this Cooler Master one can slot right on. In addition, if it's any further testament to its reliablity and efficiency, Cooler Master back it with a 10 year warranty, and it's also A-tier rated on the Cultists PSU Tier List (formerly of LTT Forums).

If you want to grab a beefy PSU for small form factor PCs at quite a discount, this deal on the Cooler Master V850 from Stocs UK on eBay is worth a look.
