Power Supply Units (PSUs)

The power supply is the one component that can take everything else with it if it fails, so it deserves more thought than it usually gets. When choosing a PSU for a gaming PC in the UK, start with wattage: add up your CPU and GPU draw, then leave 30 to 40 percent headroom so the unit runs quietly and efficiently rather than near its limit. An 80 Plus Gold rating or better is the sensible baseline for a gaming rig. Fully modular cabling is worth the small premium because it makes building easier and airflow better, with no unused cables cluttering the case. Check the warranty length too: reputable manufacturers back good units for seven to ten years, which tells you how much faith they have in the internals. Finally, make sure the unit has the right connectors for modern GPUs, including native 12VHPWR or 12V-2x6 where needed. Rig & Revive supplies reliable power supplies to UK customers from Swansea, South Wales, and we will happily sanity-check your wattage maths before you buy. Building a complete PC?
