Best Power Supplies 2026
The power supply is the component you should never cheap out on. A quality, correctly-sized PSU protects every other part and leaves headroom for upgrades; a bad one risks the whole system.
FROM THE SHOPA good chunk of the GPU upgrades that fail at our bench trace back to a tired or underspecced PSU. Don't economise here.
What to consider when choosing power supplies:
- Wattage — size for your GPU plus headroom (20–30% spare is healthy)
- 80 PLUS efficiency rating — Bronze is fine; Gold and up run cooler and quieter
- Modularity — fully modular cabling keeps builds clean
- ATX 3.0 / 12V-2x6 — needed for modern high-end GPU power connectors
COMMON MISTAKE
Buying the cheapest unbranded PSU to save money. Efficiency, protections, and reliability vary wildly — this is not the place to economise.
