Thermaltake Toughpower 1200W

This is a 1200W unit with 80+ Gold efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 1200W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

At $149.99 it sits in the high-end 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.
