Thermaltake Smart BM3 650W

This is a 650W unit with 80+ Bronze efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 650W covers a 220–300W GPU and a midrange CPU comfortably. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $59.99, which lands it among budget options. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Warranty coverage follows Thermaltake's standard policy — confirm regional terms on the listing.
