COOLER MASTER V550 SFX 80 Plus Gold 550W Power Supply

The Cooler Master V550 SFX Gold (model MPY-5501-SFHAGV-IN) is a 550-watt power supply unit built in the compact SFX form factor, designed to meet the power demands of mini-ITX system builders without sacrificing performance or reliability. Rated at 80 PLUS Gold, it achieves 90% typical efficiency, meaning less energy is wasted as heat and your electricity costs stay lower compared to less efficient units. Despite its small footprint—measuring just 100 x 125 x 63.5 mm—the V550 SFX Gold packs in a fully modular cable system, so you connect only the cables your build actually needs. This keeps cable clutter to a minimum, improves airflow inside tight cases, and makes installation cleaner. The unit ships with an SFX-to-ATX adapter bracket, allowing it to fit not just SFX enclosures but also standard ATX and E-ATX cases, giving builders unusual flexibility for a unit this size. Cooling is handled by a 92mm Fluid Dynamic Bearing (FDB) fan, which delivers quieter and longer-lasting operation compared to conventional sleeve or ball bearing fans. Active PFC ensures stable power delivery across a wide input voltage range of 90–264V and frequency range of 47–63Hz, making it suitable for Indian mains conditions. Connectivity is generous for an SFX unit: one ATX 24-pin, one EPS 8-pin, one EPS 4+4-pin, four PCIe 6+2-pin, eight SATA, and four peripheral 4-pin connectors are included. The PSU carries multiple protection circuits—OVP, OPP, SCP, OCP, UVP, OTP, surge, and inrush protection—for comprehensive system safety. It complies with SFX 12V Ver. 3.42 and is ErP 2014 Lot 3 compliant. Cooler Master backs this unit with a 10-year warranty, and the unit carries an MTBF rating of over 100,000 hours. Regulatory certifications include TUV, cTUVus, CE, BSMI, FCC, CCC, EAC, RCM, KCC, and CB.
