Introduction to Gold Efficiency

In the field of building a PC, an effective power supply unit (PSU) is essential. It functions as the heart of your system, significantly impacting performance and energy consumption. Cooler Master’s MWE Gold 850 V2 boasts Gold-rated efficiency, signaling their dedication to delivering strong performance without burdening budgets.

From my perspective, I’m always on the lookout for a PSU that hits that sweet spot between performance and price, and from the details, the MWE Gold V2 series seems promising. It comes with the assurance that a significant portion of power will reach my components without unnecessary loss—a godsend for any power-conscious user. Here’s a quick rundown of the perks and what could be better:


  • With an Enhanced Efficiency 80 PLUS Gold rating, this power supply delivers up to 90% efficiency. This superior energy conversion results in less energy wasted and reduced heat production when compared to less efficient models.

  • Fully Modular Design: This design offers advantages in terms of organization and airflow. It simplifies the look and eliminates clutter.

  • Temperature Endurance: This device can function effectively at temperatures up to 50 degrees Celsius.

Why It Could Be Better

  • The HDB fan’s Fan Quality receives mixed feedback from users. Some report an unbalanced sound which might indicate a production issue that requires resolution.

  • Inconsistencies with Cables: There’s feedback indicating that the cables may not plug in completely, which could be a design flaw or a manufacturing oversight.

With these considerations in mind, the MWE Gold V2 balances affordability and environmental responsibility effectively. Although concerned about reported fan noises, I believe it’s a reasonable compromise given the unit’s overall worth. Regarding cable issues, I prefer taking a cautious approach due to the importance of stable connections.

A personal preference I value is the addition of two EPS connectors in the Cooler Master MWE Gold V2. This feature broadens motherboard compatibility and offers some level of future-proofing. However, it’s essential for Cooler Master to prioritize build quality and consider user feedback if they aim to establish the MWE Gold V2 as a symbol of reliability.

As someone considering a new build, I’m drawn to the MWE Gold V2 due to its impressive feature set and affordable price. While some concerns have been raised by the community, these factors make it an appealing choice for those seeking a powerful and efficient system.

Design and Connectivity

In my search for a new power supply, the MWE Gold 850 V2 stood out for several reasons:

  • Detachable Cables: Each cable can be removed, minimizing clutter.

  • Flat Black Cables are practical for use in tight spaces due to their slim design.

  • Improved Connectivity: The new model includes two EPS connectors, which is a step up for compatibility.

Right out of the box, the modular design is a significant improvement for me due to my dislike for excess clutter. The flat black cables are both visually appealing and practical; they’re flexible and simple to adjust within a case, maximizing space and enhancing airflow.

From a connectivity standpoint, I’m glad Cooler Master incorporated two EPS connectors into the design. This allows for compatibility with newer motherboards. The connectors fit securely, but the cables could be more cooperative in smoothly fitting. Having the assurance of not needing additional purchases for compatibility is beneficial.

The look is straightforward and sleek. The cables blend seamlessly into the dark case interior. Installing the power supply was familiar. However, I hesitated when I felt the cables didn’t snap into place as securely as anticipated. They are firmly connected but a slight gap remains, unsettling those who crave perfection.

When exploring the 120mm HDB fan, its quiet operation is a pleasant surprise due to its minimal noise production. However, I’m curious as to why it consistently runs at full speed. While it effectively cools without complications, I question the absence of a zero RPM mode featured in some other brands.

The power supply is robust, managing the energy demands of a gaming session effectively without any sign of strain. With a capacity of 850 watts, it offers sufficient space for future component enhancements, a consideration I frequently keep in mind.

In the larger context, the MWE Gold 850 V2 offers noteworthy design and connectivity improvements. Although there are a few minor issues, the benefits of modular design, cable management, and strong power delivery are significant. Cooler Master prioritizes functionality and user understanding, even if some might prefer more refinement in the finer details.

Performance and Usability

When using the MWE Gold 850 V2, my experience has been largely positive. With its 80 PLUS Gold efficiency, this power supply ensures efficient energy flow for my PC, reducing energy waste and allowing me to focus on performance. As a power user, this stability is a significant selling point for me.

The fully modular design simplifies cable management. Each cable serves a purpose, and the sleek black appearance is both visually appealing and functional. Additionally, the 850-watt output provides sufficient power for my components without risk of overloading.

Key Features I Appreciated:

  • 80 PLUS Gold efficiency for optimal power usage

  • Two motherboard connectors are included with the EPS.

  • High operating temperature tolerance

  • The design is fully modular with flat black cables for convenient cable management.

  • A 120mm Hydro Dynamic Bearing fan ensures quiet operation.

However, this product has some drawbacks despite its high durability rating. Some users have reported early failures, so I now recommend testing the power supply before installation. The modular cables don’t fit as snugly as expected, which can be frustrating.

I have observed that the fan noise level is not consistent. Although it doesn’t disturb me significantly, it may be an issue for some users who expect absolute silence from their system, as previous power supplies had fanless modes. This could potentially cause dissatisfaction among those seeking quiet operation.

In terms of performance, the MWE Gold 850 V2 met my expectations by smoothly handling my demanding applications. I tested its capabilities through extensive gaming sessions and intensive tasks without encountering any issues. The power supply’s robust construction and efficiency contributed significantly to its dependability during these challenges.

Despite the small issues like cable fit imperfections and occasional need for pre-testing due to defective units, Cooler Master’s MWE Gold 850 V2 power supply generally delivers a good user experience. With consistent warranty support and customer service, this power supply is an excellent option for builders seeking a balance between top performance and a tidy interior workspace.
