Montech APX 550W

This is a 550W unit with 80+ efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 550W covers mainstream builds with a modest GPU. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $49.90 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. Montech backs the product through its standard warranty channels; check the listing for region-specific terms. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
