DEEPCOOL Gamer Storm PN1200M 1200W 80 Plus Gold Fully Modular ATX 3.1 Power Supply

The Deepcool Gamer Storm PN1200M is a 1200W fully modular ATX 3.1 power supply built for demanding high-performance PC systems. Carrying the 80 Plus Gold efficiency certification, it delivers at least 90% efficiency under typical 50% loading conditions, reducing wasted heat and energy costs over long usage periods. The unit also holds a Gold rating from Cybenetics, providing independent third-party validation of its efficiency performance. At the heart of the PN1200M is a topology combining Active PFC, a Half-Bridge SRC LLC stage, and a DC-to-DC conversion stage. This architecture contributes to tight voltage regulation and a hold-up time of 16 ms or greater at 80% load, meaning brief power interruptions are less likely to cause a system shutdown. Japanese bulk capacitors are used throughout, a common indicator of component quality in power supply design. For modern GPU compatibility, the PN1200M includes a high-grade 105°C-resistant 16AWG copper-core 12V-2×6 cable capable of delivering up to 600W to a single graphics card — fully in line with the PCIe 5.1 connector specification. The ATX 3.1 standard compliance means it can also handle transient power spikes by providing twice the rated power for 0.1 ms, keeping next-generation GPUs stable under burst loads. Cooling is handled by a 135mm Fluid Dynamic Bearing (FDB) fan that adjusts speed dynamically based on internal thermal conditions, balancing noise and airflow as needed. The unit is rated for operation between 0°C and 40°C and is specified to function at altitudes up to 5,000 metres above sea level. A comprehensive protection suite — OPP, OVP, SCP, OTP, OCP, UVP, SIP, and NLO — guards connected components against power anomalies. The compact 150×150×86 mm (W×L×H) chassis fits the vast majority of ATX cases without clearance issues. The PN1200M is backed by a 10-year limited warranty from Deepcool, and the unit carries CE, FCC, CCC, TÜV-RH, cTÜVus, RCM, EAC, and BIS regulatory certifications. MTBF is rated at 100,000 hours.
