Silverstone SX650-G 650W

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