What to check before buying

Complete system power

Use the exact CPU and graphics card, include the rest of the system and compare the result with the GPU manufacturer's PSU recommendation.

Connectors and standards

Confirm the number and type of CPU, GPU, SATA and motherboard connectors. Never reuse modular cables from a different power supply.

Quality and form factor

Check independent technical reviews, warranty, electrical protections and whether the case requires ATX, SFX or another PSU size.
