SAMA GT 850W

This is a 850W unit with 80+ Gold efficiency certification and full cabling. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. It uses the ATX form factor — confirm your case lists ATX support. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Expect to pay around $54.99, which lands it among budget options. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. Support and warranty service run through SAMA, with terms that vary by region.
