I'm looking for a reliable power supply for a system with an RTX 5080 and Ryzen 7 5800X3D. I'd prefer to spend around £100 or less, although I can go slightly over if it's worthwhile. What models or specifications should I be looking for?

A good target would be an 850W unit with 80 Plus Gold efficiency and a strong reliability rating. One option worth checking is the Montech Titan Gold 850W, which is fully modular, A+ rated, and may be available for around £80 depending on current pricing.
Try to avoid cutting costs too aggressively on the PSU. Look for an A or A+ rated model with Gold efficiency or better, and make sure it physically fits your case. Around £100 may be slightly tight for a high-quality unit, but sales can make it possible.
An 850W Gold-rated PSU is a sensible choice for this hardware. Pricing varies by region, so compare reputable models rather than choosing solely by wattage. It’s better to spend a little more on a dependable unit than risk pairing expensive components with a cheap power supply.

Thanks, I’ll focus on A or A+ rated Gold units and check that the dimensions and connectors work with my case.
