CORSAIR CX550 550W 80 PLUS Bronze ATX Power Supply

Description

Overview

The CORSAIR CX550 is a 550 watt ATX power supply offering 80 PLUS Bronze efficiency in a compact 125mm-long chassis. Designed for mainstream desktop and gaming systems, the CX550 provides a single strong +12V rail, a thermally‑controlled 120mm low‑noise fan and fully wired cables for straightforward installation.

Key features

• 550W continuous power with up to ~88% efficiency under typical loads (80 PLUS Bronze certified).
• Compact 125mm depth for easy fitting in most modern PC cases.
• 120mm sleeve‑bearing fan with thermal control to reduce noise at lower loads.
• Fully wired (non‑modular) cable set including ATX 24‑pin, 1× EPS 8‑pin (4+4), 2× PCIe 6+2 pin connectors, 3× SATA and 2× Molex connectors.
• Single +12V rail (44A / 528W) and ATX12V v2.31 compatibility.
• Five‑year manufacturer warranty and global safety declarations.

This model is appropriate for builders who want a reliable, compact PSU for mid‑range CPU/GPU combinations where a fully‑wired, easy‑install power supply is acceptable. It is not a modular unit — if you require detachable cables for cable management, check Corsair’s CX‑M (semi‑modular) or other modular variants.

Package contents include the CX Series ATX power supply, an AC power cord, mounting screws and warranty/manual documentation.
