This is a 650W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 650W covers a 220–300W GPU and a midrange CPU comfortably. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Expect to pay around $99.99, which lands it among mid-range options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
