Silverstone ATTIS 750R 750W

This is a 750W unit with 80+ Bronze efficiency certification and non-modular 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.

Expect to pay around $157.99, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows Silverstone's standard policy — confirm regional terms on the listing. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
