SeaSonic SSP-300SUG 300W

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

Expect to pay around $115.99, which lands it among high-end options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers.
