Rosewill Tachyon 750W

This is a 750W unit with 80+ Platinum efficiency certification and semi cabling. 750W covers a 220–300W GPU and a midrange CPU comfortably. It uses the ATX form factor — confirm your case lists ATX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $55.99 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. Rosewill 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.
