GIGABYTE P550SS Ice 80+ Silver Non-Modular ATX 3.0 Power Supply ( 550W ) ( White )

The GIGABYTE P550SS Ice (model GP-P550SS-ICE) is a 550W non-modular power supply finished in white, designed for builders who want a clean, efficient, and future-ready foundation for their PC. Carrying the 80 PLUS Silver certification at 230V EU, this unit delivers up to 90% efficiency at typical load, which translates directly into less wasted electricity, lower operating temperatures, and reduced fan noise during everyday tasks and gaming sessions. Compliance with the Intel ATX 3.0 form factor standard — and backward compatibility with ATX 3.1 — means the P550SS Ice is ready for modern graphics cards that demand instantaneous power spikes. The unit supports up to 200% power excursion as defined in Intel's Power Supply Design Guide (PSDG), ensuring that transient loads from high-performance GPUs are handled without voltage instability. The single +12V rail design further simplifies cable management and maximises power delivery to your most demanding components. Cooling is handled by a 120mm Fluid Dynamic Bearing (FDB) fan. Unlike conventional sleeve-bearing fans, the FDB design uses an oil-film shock absorption mechanism to reduce operating noise and extend service life. The fan's speed is regulated automatically based on real-time load and temperature readings, so the PSU remains near-silent during light usage and only ramps up when required. Flat, all-black cables are included throughout, improving airflow inside the chassis and making routing tidier compared to round-sleeved alternatives. The connector set covers all standard PC peripherals without requiring adapters on most mid-range builds. Six hardware protection circuits — Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Over Temperature Protection (OTP) — safeguard both the PSU and connected components from electrical faults. GIGABYTE backs this unit with a 3-year warranty (terms vary by region).
