OCZ StealthXstream II 700W

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

PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through OCZ, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
