Thermaltake Rome 750W

A 750W unit with 80+ Gold efficiency certification and semi 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.

At $99.99 it sits in the mid-range power supply bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers.
