DeepCool PN850D 850W Power Supply Review
Table of Contents
Introduction
The DeepCool PN850D is a non-modular power supply (PSU) aimed at budget-conscious PC builders. This 850W unit boasts 80 Plus Gold certification, promising high efficiency and lower energy consumption. In this review, we delve into its performance, features, and overall value proposition.
Features
The PN850D comes packed with features that make it a compelling option for its price point. Here’s a closer look:
- 80 Plus Gold Certification: This certification guarantees high efficiency levels, translating to lower energy bills and less heat generation.
- 120mm Hydro Bearing Fan: The fan utilizes a hydrodynamic bearing for quiet operation and longevity.
- Active PFC + Full Bridge SRC LLC + DC to DC Topology: This advanced topology ensures stable voltage output and improved power delivery.
- Comprehensive Protection Features: The unit includes multiple protection mechanisms (OPP/OVP/SCP/OTP/OCP/UVP/SIP/NLO) to safeguard your PC components.
- Non-Modular Design: While a modular design offers flexibility, non-modular PSUs like the PN850D are often more budget-friendly.
