The PC power supply for serious South African builders
Every custom PC build in South Africa demands a foundation of reliable power. The Cougar STC550 is a 550W PC power supply engineered for stability, designed to support modern mid-range components without compromise.

Stable efficiency, serious protection from this PSU
An 80 PLUS 230V EU Standard rating means this PSU converts up to 86% of AC input into usable DC power, significantly reducing wasted heat. Active PFC with a power factor up to 99% minimises electrical noise and ensures clean delivery to sensitive components. Robust safeguards are built-in: OCP, OPP, OVP, UVP, and SCP offer comprehensive defence against unexpected surges.

Reliable power delivery to every component
The single +12V rail delivers 42 A (504 W) to your CPU and GPU, crucial for demanding tasks like gaming or rendering. This dedicated rail design ensures stable voltage delivery, preventing performance bottlenecks under heavy load.

Cool and quiet operation for focused builds
A 120mm cooling fan keeps the Cougar STC550 operating at optimal temperatures, even under full load in a warm Johannesburg study. The robust thermals protect the 105C Japanese standby capacitors, extending their operational life.

Extensive connectivity for modern PC power supply needs
A 24-pin main connector (20+4) ensures broad motherboard compatibility. You get a single 8-pin (4+4) CPU/EPS connector, two 8-pin (6+2) PCIe connectors, five SATA connectors, and two peripheral (Molex) connectors.

The Cougar STC550: A foundation built to last
With an operating temperature of up to 40C ambient, this PC power supply performs reliably through the South African summer. The non-modular design means less fuss for new builders and a secure connection for every cable.

FEATURES
- Protect your components: Comprehensive OCP, OPP, OVP, UVP, SCP guard against power fluctuations.
- Maximise efficiency: 80 PLUS 230V EU Standard minimises wasted energy and heat generation.
- Deliver stable power: 550W output with a dedicated 42 A +12V rail handles demanding GPUs.
- Stay cool and quiet: 120mm fan manages thermals without intrusive noise.
- Ensure longevity: 105C Japanese standby capacitors provide extended reliability.
- Connect your hardware: Comprehensive cable set with 2x PCIe 8-pin and 5x SATA connectors.
