DeepCool PN650D 450W ATX Power Supply

DeepCool PN650D | 450W ATX 3.1 Gold PSU with PCIe 5.1

The DeepCool PN650D 450W Power Supply, ATX, 12V V3.1, 80 PLUS Gold, Non-Modular, 120mm Hydro Bearing Fan, PCIe 5.0, 10-Year Warranty delivers stable, efficient power for modern high-performance systems. Built to Intel ATX 3.1 and PCIe 5.1 standards, it provides reliable support for demanding GPUs and components with clean, gold-rated efficiency.

Specification Overview

Modern GPU Ready with PCIe 5.1 Support

The PN650D is equipped with a dedicated 12V-2×6 connector and three PCIe outputs, offering up to 450W of clean power for the latest graphics cards. With PCIe 5.1 compliance, it ensures stable delivery under heavy GPU loads, making it ideal for gaming rigs and content creation workstations using modern hardware.

Efficient Performance with Gold Certification

Rated 80 PLUS Gold and Cybenetics Gold, the PN650D achieves over 90% efficiency under typical loads. This high efficiency reduces heat output and power waste, helping keep system temperatures lower and electricity costs down over long-term use.

Advanced Protection and Reliability

Built with active PFC, full-bridge SRC LLC, and DC-to-DC topology, the PSU delivers stable voltage with a hold-up time of at least 16ms under 80% load. Multiple protections—including OPP, OVP, SCP, OTP, OCP, UVP, NLO, and SIP—guard against electrical faults and ensure safe, consistent operation.

Quiet Cooling with Dynamic Fan Control

The 120mm hydro bearing fan adjusts its speed automatically based on system load, keeping noise to a minimum during light use while ramping up when cooling is needed. This dynamic control improves acoustics and extends fan life compared to fixed-speed designs.

Premium Build Quality for Long-Term Use

High-quality components, including a premium main electrolytic capacitor and 105°C-rated sleeved cables, allow the PN650D to operate reliably at altitudes up to 5000 metres. The sleeved cables add a neat, professional look inside your build while improving airflow and durability.
