Montech CENTURY 650W

This is a 650W unit with 80+ Gold efficiency certification and full 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.

Its $43.20 price tag places it squarely in budget territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Warranty coverage follows Montech's standard policy — confirm regional terms on the listing. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
