Thermaltake Smart BM3 650W Bronze

A 650W 80 Plus Bronze, semi-modular unit, the Smart BM3 stands out for including a native 12V-2x6 connector — uncommon in its entry tier. It's a tidy ATX 3.x choice for a modest GPU. Note the two ceilings: the 16-pin tops out at 300W so power-hungry cards are off the table, and Bronze efficiency won't satisfy efficiency-focused builders.
