DeepCool PN850D 850W ATX Power Supply

DeepCool PN850D | 850 W ATX 3.1 Gold Power Supply

The DeepCool PN850D power supply unit 850 W 20+4 pin ATX ATX Black delivers stable, high-efficiency power for modern gaming and workstation PCs. With ATX 3.1 and PCIe 5.1 compliance, this non-modular PSU provides reliable performance for both legacy and next-generation components.

Key Specifications

Future-Proof Power Delivery

The PN850D is engineered to handle demanding modern hardware with its ATX 3.1 compliance and dedicated 12V-2×6 connector. This configuration provides three times the GPU power excursion tolerance for 0.1 ms, ensuring stable operation during power spikes from high-performance graphics cards. With 2 EPS and 3 PCIe connectors plus one 16-pin PCIe 5.1 connector, this PSU supports the latest GPU architectures while maintaining compatibility with older systems.

Gold Efficiency Meets Cybenetics Certification

Achieving 80 PLUS Gold certification means the PN850D operates at over 90% efficiency under typical loads, reducing wasted energy and heat output. The Cybenetics Gold rating further validates this power supply’s exceptional performance across various load conditions. This efficiency translates to lower electricity bills and cooler system operation, particularly beneficial for users running their PCs for extended periods or in warmer environments.

Built-In Protection Systems

Comprehensive safety features protect both the PSU and connected components from electrical faults. The PN850D includes over-power protection (OPP), over-voltage protection (OVP), short-circuit protection (SCP), over-temperature protection (OTP), over-current protection (OCP), under-voltage protection (UVP), no-load operation capability, and surge & inrush protection (SIP). These safeguards provide peace of mind for users building valuable systems, preventing damage from unexpected power fluctuations.
