Thermaltake Toughpower Grand 700W

This is a 700W unit with 80+ Platinum efficiency certification and semi cabling. 700W covers a 220–300W GPU and a midrange CPU comfortably. It uses the ATX form factor — confirm your case lists ATX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

At $54.99 it sits in the budget 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. Support and warranty service run through Thermaltake, with terms that vary by region.
