Gigabyte AORUS P GM 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. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Its $89.99 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. Warranty coverage follows Gigabyte's standard policy — confirm regional terms on the listing.
