Cooler Master GX III Gold 850 Overview: A Decade of Excellence
In my years of building computers, I’ve seen a wide range of power supplies. From budget options that often failed prematurely to premium choices that delivered reliable performance. Cooler Master’s Elite series was a popular choice among enthusiasts, known for its durability and consistent operation, even without 80+ certification.
For my high-end builds, I turned to Cooler Master’s GX series, which offered 80+ certification, sleeved cables, and a larger cooling fan. In the 2010s, Cooler Master dominated Malaysia’s PSU and case markets.
Today, we’re checking out the Cooler Master GXIII Gold 850, a continuation of this legacy. This fully-modular 850W unit boasts an 80+ Gold efficiency rating, making it an attractive option for PC builders seeking a balance of performance and value.
This overview will explore the key features of the Cooler Master GXIII Gold 850 and assess its capabilities through various tests.
Cooler Master GX III Gold 850 Overview
The Cooler Master GXIII Gold 850 builds upon its predecessor, the GXII series, with a focus on improved efficiency and quieter operation. It retains the popular fully-modular design, allowing for a clean and clutter-free build.
The PSU features a sturdy metal casing with one side vents for airflow. A large fan, nearly the size of the PSU itself, dominates the top panel, suggesting its ability to cool even the most demanding components.
The front of the PSU showcases the fully-modular design, allowing for a clean and organized build. The GXIII also supports 12VHPWR, making it a suitable choice for modern GPUs.
Cooler Master includes a 90-degree 12VHPWR cable, enabling a neater build without the need for aftermarket options.
It’s worth noting that the PSU supports ATX 3.0, capable of delivering up to 450W under load. For those seeking the highest power delivery, Cooler Master offers an ATX 3.1 version.
Focus on Quiet Performance
The GXIII Gold 850 utilizes a 135mm fan with Hydro Dynamic Bearing for quiet and efficient cooling. This design minimizes noise generation, making it ideal for noise-sensitive users.
The PSU also features a Zero-RPM mode, where the fan won’t spin until the temperature reaches a certain level. This function has received a Cybenetics A- noise level certification, indicating that even at full load, it won’t exceed 30 dB(A) and will typically remain within the 25 dB(A) range.
| Cybenetics Noise Level Certifications | Noice Level |
| A++ | < 15 dB(A) |
| A+ | 15 dB(A) ~ 20 dB(A) |
| A | 20 dB(A) ~ 25 dB(A) |
| A- | 25 dB(A) ~ 30 dB(A) |
| Standard++ | 30 dB(A) ~ 35 dB(A) |
| Standard+ | 35 dB(A) ~ 40 dB(A) |
| Standard | 40 dB(A) ~ 45 dB(A) |
80+ Gold + Cybenetics Platinum
The Cooler Master GXIII Gold 850 boasts dual certifications that underscore its efficiency and performance. First, it has 80+ Gold certification, guaranteeing a minimum efficiency of 90% at 50% load, 89% at 20% load, and 87% at 10% load. This means less energy is wasted as heat, leading to lower operating costs and reduced noise.
Second, it holds Cybenetics Platinum certification, which requires an even higher efficiency standard: 94% at 50% load, 92% at 20% load, and 90% at 10% load. This demonstrates the PSU’s exceptional ability to convert electrical power into usable energy, making it a highly efficient and cost-effective choice for PC builders.
