Athena Power AP-MTFX30 300W

This is a 300W unit with 80+ efficiency certification and non-modular cabling. 300W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $36.99, which lands it among budget options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through Athena, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
