Full review
80 PLUS Gold efficiency verified
The Cooler Master MWE Gold 850 V2 achieves verified 80 PLUS Gold efficiency ratings, with measured performance indicating up to 90% efficiency in real-world usage. Paul Norvig says this level of efficiency ensures minimal energy waste and reduced heat generation compared to less efficient models. The power supply's ability to maintain this standard across a range of loads makes it suitable for users who prioritize both performance and energy consumption. Reviewers noted that the efficiency rating translates to tangible benefits in system stability and lower electricity costs over time.
Fully modular design with flat cables
The unit features a fully modular design with flat black cables that provide practical advantages in tight spaces. The flat cable design allows for better airflow and easier cable management within the case. Users reported that the modular approach significantly reduced internal clutter and improved overall system organization. Paul Norvig describes the cables as flexible and simple to adjust within a case. The flat black cables blend seamlessly into dark case interiors, contributing to a clean aesthetic while maintaining functionality.
Single 120mm fan with constant operation
The power supply incorporates a single 120mm fan that operates continuously at full speed, a design choice that ensures consistent cooling but introduces some trade-offs. While the constant fan operation keeps internal components cool and extends their lifespan, it also creates audible noise under high load conditions. Reviewers noted that the fan produces minimal noise under normal operation but becomes noticeable during peak usage. The lack of zero RPM functionality means that dust accumulation is a potential concern, though the continuous operation also prevents dust from settling on components during idle periods.
Two EPS connectors for motherboard compatibility
According to Paul Norvig, the inclusion of two EPS connectors represents an upgrade over previous models, enhancing motherboard compatibility and future-proofing. This feature allows for easier connection to newer motherboards that require dual EPS connections. Users reported that the EPS connectors fit securely and provide reliable power delivery to the CPU. The dual connector design eliminates the need for additional adapters or cables, simplifying the build process. However, Paul Norvig relays feedback that the cables may not plug in completely.
850-watt output for high-end builds
With 850 watts of total output, the power supply is capable of supporting high-end PC configurations, including systems with powerful CPUs like the Ryzen 7 7800 X3D and high-end GPUs such as the RTX 490 or RX 7900 XTX. Reviewers confirmed that the unit delivers stable power under load, handling demanding components without performance drops or instability. The single 12-volt rail design ensures that the full power output can be delivered to the CPU without voltage drops. Users noted that the power supply provides sufficient headroom for future upgrades, making it a solid choice for long-term builds.
No PCIe 5.0 high power cable included
The power supply does not include a PCIe 5.0 high power cable, requiring users to purchase an adapter separately if their GPU requires this specific connector type, per BC Zone. This limitation is particularly relevant for newer high-end graphics cards that utilize the 12VHPWR connector. Reviewers pointed out that while the standard 6-pin and 8-pin PCIe connectors work well for most applications, users with newer GPUs may need to invest in additional accessories. The absence of this cable is a notable drawback for those building with the latest hardware, though it does not affect compatibility with older or standard PCIe connectors.
Warranty and build quality concerns
The unit comes with a five-year hardware warranty, which provides peace of mind for users investing in the power supply. However, Paul Norvig relays feedback about inconsistencies with the cables, with reports of them not plugging in completely. The build quality of the unit is generally solid, though Paul Norvig notes mixed user feedback on the fan, with some reports of an unbalanced sound. The use of standard components rather than premium parts like those from Infineon on the primary side has been noted, though the long warranty period suggests confidence in the overall reliability of the unit.
Strengths
- +80 Plus Gold certified efficiency rating
- +Fully modular cable management system
- +Includes five-year hardware warranty
- +Upgraded fan with improved airflow
- +Two EPS connectors for high-end builds
Watch-outs
- −No native 12VHPWR connector and no zero-RPM fan mode
How it compares
The Cooler Master MWE Gold 850 V2 provides 80 Plus Gold efficiency and two EPS connectors, but lacks the 10-year warranty of the Corsair RM850x and Seasonic Focus GX-850. It's less efficient than the EVGA SuperNOVA 850 G7 and doesn't match the be quiet! Dark Power Pro 12 850W in noise control or build quality, though it does offer a five-year warranty.
