DEEPCOOL PF550 Standard Non Modular Power Supply (550 W)

The Deepcool PF550 is a 550-watt, non-modular ATX power supply designed for budget-conscious PC builders who still want reliable, certified efficiency. Built to the ATX12V V2.4 standard, it carries an 80 Plus 230V EU White certification, meaning it delivers at least 85% efficiency under typical 50% load conditions. That headroom helps reduce heat inside your chassis and keeps electricity costs in check over the life of the build. Cooling is handled by a 120mm fan fitted with a Hypro Bearing — a hydraulic-style bearing that reduces friction and vibration compared with sleeve-bearing alternatives, contributing to quieter day-to-day operation. The unit uses an Active PFC plus double-forward tube topology and sources its bulk capacitors from Taiwanese manufacturers, a detail that points to reasonable component quality for this price tier. Cabling is fixed (non-modular) and finished in flat black, which eases routing through tight spaces and behind motherboard trays. Connectivity includes 2× PCIe (6+2-pin), 6× SATA, and 2× peripheral (4-pin) connectors — enough for a mainstream single-GPU build with multiple storage drives. Protection circuits cover over-power (OPP), over-voltage (OVP), and short-circuit (SCP) events, giving a meaningful safety net for your components. The unit holds its power-good signal for 100–500 ms and maintains hold-up time of at least 16 ms at 75% load. Regulatory approvals span CB, CCC, CE, UKCA, EAC, RCM, and BIS, confirming compliance across multiple markets including India and the UK. The PSU carries a rated MTBF of 100,000 hours and is backed by a 3-year manufacturer warranty.
