DEEPCOOL Gamer Storm PN850D 850W 80+ Gold Non Modular ATX 3.1 Power Supply

The Deepcool Gamer Storm PN850D is an 850-watt ATX12V V3.1 power supply designed to deliver reliable, clean power to modern and upcoming gaming systems. Certified 80 Plus Gold, it achieves at least 90% efficiency under typical load conditions (50% loading), which means less energy is wasted as heat and your system runs cooler and quieter. At the heart of the PN850D is a topology combining Active PFC, Half-Bridge SRC LLC, and DC-to-DC conversion — an arrangement that keeps voltage rails stable and reduces ripple even under demanding workloads. A Japanese bulk capacitor is used as the main electrolytic component, contributing to a hold-up time of 16 ms or more at 80% load and a power good signal window of 100–150 ms, both of which help protect your system during brief power interruptions. For GPU connectivity, the PN850D ships with a high-grade 16AWG copper-core sleeved 12V-2x6 cable, delivering up to 600W to PCIe 5.1-compatible graphics cards. This makes it well-suited for high-end discrete GPUs that demand surge headroom well beyond their rated TGP. All cables are sleeved from the factory, providing a cleaner look inside the chassis without requiring additional cable management accessories. Cooling is handled by a 135mm Fluid Dynamic Bearing (FDB) fan that adjusts its speed based on thermal load. FDB fans are known for longevity and low noise, and Deepcool rates the PN850D at a mean time between failures (MTBF) of 100,000 hours, backed by a 10-year manufacturer warranty. The unit carries a comprehensive protection suite — OPP, OVP, SCP, OTP, OCP, UVP, SIP, and NLO — and is certified across multiple regulatory frameworks including CE, FCC, CCC, TUV-RH, cTUVus, RCM, EAC, and BIS. It also complies with ErP 2014, WEEE, RoHS, Triman, and P65 environmental standards.
