DeepCool Gamer Storm PN750M Gold ATX 3.1 Fully Modular SMPS

The DEEPCOOL Gamer Storm PN750M is a 750-watt fully modular power supply designed for both current and next-generation PC builds. Conforming to the ATX12V V3.1 standard, it is equipped with a native 12V-2x6 connector that can supply up to 450 watts to modern high-performance GPUs, making it a practical choice for systems built around demanding discrete graphics cards. Efficiency is a core strength of the PN750M. Certified 80 Plus Gold, the unit delivers at least 90% efficiency under typical load conditions (50% load), and it carries an additional Gold-level rating from Cybenetics. The underlying power topology combines Active PFC, a Full-Bridge SRC LLC stage, and a DC-to-DC converter — an architecture associated with tight voltage regulation and low ripple across all rails. A primary Japanese electrolytic bulk capacitor forms the foundation of the filtering stage, contributing to a hold-up time of 16 milliseconds or greater under 80% load, comfortably exceeding ATX specification minimums. The Power Good signal is issued within 100–150 ms of startup, providing reliable sequencing for platform components. Thermal management is handled by a 120 mm Fluid Dynamic Bearing (FDB) fan, which modulates its speed in proportion to the actual heat load inside the unit. FDB fans are recognised for low noise at light loads and extended operational lifespan compared to sleeve-bearing alternatives. The PSU is rated to operate continuously in ambient temperatures from 0 °C to 40 °C and at altitudes up to 5,000 metres above sea level. All cables are sleeved from the factory. The fully modular design means only the cables needed for a given build need be connected, reducing internal cable clutter and improving airflow inside the chassis. Protection suite: Over-Power Protection (OPP), Over-Voltage Protection (OVP), Short-Circuit Protection (SCP), Over-Temperature Protection (OTP), Over-Current Protection (OCP), Under-Voltage Protection (UVP), Surge & Inrush Protection (SIP), and No-Load Operation (NLO) protection are all confirmed active. The unit carries a 10-year warranty and a Mean Time Between Failures (MTBF) rating of 100,000 hours.
