DeepCool PL550D Bronze 550W ATX 3.1 SMPS

The DeepCool PL550D is a 550-watt non-modular power supply built to the ATX12V V3.1 standard, making it a forward-compatible choice for both current and next-generation PC builds. Certified 80 Plus Bronze, the unit delivers at least 85% efficiency under typical load (50% loading), helping to reduce heat output and energy waste compared to uncertified alternatives. Power delivery is handled through a dual-transistor forward topology combined with active power factor correction (Active PFC) and DC-to-DC voltage conversion, which together contribute to tighter voltage regulation across all rails. A native 12V-2x6 (PCIe 5.1) connector rated up to 300W is included, ensuring compatibility with the latest discrete graphics cards without the need for adapter cables. The connector set also includes three PCIe connectors, two EPS connectors, two SATA connectors, two peripheral (4-pin Molex) connectors, and the standard 24-pin ATX motherboard connector. Cooling is managed by a 120mm fan using a hydro bearing (HYB), a design known for quieter operation and extended service life compared to sleeve-bearing alternatives. The PSU operates reliably within an ambient temperature range of 0°C to 40°C and is rated for use at altitudes up to 5,000 metres above sea level. Protection circuitry covers OPP (over-power), OVP (over-voltage), SCP (short-circuit), OTP (over-temperature), OCP (over-current), UVP (under-voltage), SIP (surge & inrush protection), and NLO (no-load operation), providing a comprehensive safety envelope for connected components. Hold-up time is rated at 16ms or greater under full load, and the power-good signal window is 100–150ms. Regulatory approvals include CE, FCC, CCC, RCM, EAC, CAN ICES-003(B)/NMB-003(B), and TÜV-RH. The stated MTBF is 100,000 hours, and the unit is backed by a 5-year manufacturer warranty.
