Silverstone ST75F-GS-V3 750W

A 750W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 750W 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.
