This is a 550W unit with 80+ Bronze efficiency certification and full cabling. 550W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Expect to pay around $14.99, which lands it among budget options. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. OCZ backs the product through its standard warranty channels; check the listing for region-specific terms.
