Gigabyte UD-GM PG5 850W

This is a 850W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $109.99 price tag places it squarely in mid-range territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Gigabyte backs the product through its standard warranty channels; check the listing for region-specific terms.
