Thermaltake Smart DPS G 750W

A 750W unit with 80+ Gold efficiency certification and semi cabling. 750W 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 $79.99 it sits in the mid-range power supply bracket. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total. Thermaltake backs the product through its standard warranty channels; check the listing for region-specific terms. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
