Cooler Master V750 Gold Power Supply Review

The Cooler Master V750 Gold has modest lineage. The Cooler Master V850, its sibling, has high build quality and registers a satisfactory overall performance, but it can be noisy, under harsh operating conditions, and to make matters worse, it is expensive. With notably less money, you can get a better power supply, including the Seasonic Focus Plus Gold with similar capacity, and the Corsair RM750x and RM750.

We had reviewed the previous generation V750 model back in 2015. Enhance Electronics provided the platform, which featured compact dimensions, thanks to a "3D" circuit that was used, which was just a fancy description for a daughter-board used to transfer the +12V rail to the modular PCB.

The newer V Gold units are made by Chicony Electronics, and the line consists of four models, with capacities ranging from 550W to 850W. They are fully modular, and besides 80 PLUS, they are also certified by Cybenetics, with all of them achieving ETA-A efficiency certifications. In the noise output section, Cybenetics rated them from LAMBDA-S++ (V850) to LAMBDA-A (V550).

The V750 Gold is the second strongest member of the line. A good 750W power supply can easily support a potent system, equipped with a high-end CPU and a strong GPU (e.g., Nvidia RTX 2080Ti or AMD RX 5700 XT). If you need to use a pair of 2080Ti cards, along with an AMD Ryzen 9 or an Intel i9 CPU, you will have to get a power supply with at least 1000W power, to have peace of mind. A 2080Ti can consume up to 250W of power, so two of them reach 500W, while a Ryzen 9 3900x is at 150W, with the i9-9900K hitting more than 220W even at stock speeds and settings.

Cables & Connectors

There are two EPS connectors and four PCIe ones, which are more than enough for a 750W PSU. The number of peripheral connectors is satisfactory as well, with twelve SATA and four 4-pin Molex connectors. The only issue is the small distance between the connectors above. Finally, there are no in-cable caps, which can make the PSU installation process tough, especially in chassis that don't have large perforations and/or enough space behind the mainboard's tray, for cable routing.

Overall Photos

On the primary side, we find a half-bridge topology and an LLC resonant converter, for increased efficiency. The heat sinks are not large, and the design looks clean with enough clearance between components for good airflow. Overall, this is a well-made platform featuring a contemporary design.

Transient filter and bridge rectifiers

There is no MOV in the transient filter, which is a shame. Moreover, there is no inrush current limiter in the form of an NTC thermistor. So we expect high inrush current readings.

Bridge Rectifiers

Both bridge rectifiers are bolted onto the primary heat sink.

APFC Converter

The APFC converter uses a quality bulk cap, rated at 450V. The corresponding controller is provided by Infineon (ICE3PCS03G).

Main FETs and primary transformer

The main FETs are arranged in a half-bridge topology, and an LLC resonant decreases the switching losses. The resonant controller is an MPS HR1000A IC, accompanied by two MP6903 ICs.

12V FETs and VRMs

The +12V FETs are installed on the solder side of the PCB. The same rail feeds a pair of DC-DC converters which generate the minor rails.

Filtering caps

All filtering caps, both electrolytic and polymer, are of high quality and are provided by Japanese manufacturers.

Modular board front

The modular board is enhanced by bus-bars, for lower losses on power transfers. Many polymer caps are also installed for ripple filtering purposes.

5VSB Circuit

A large daughter-board hosts the 5VSB circuit. 

The supervisor IC, responsible for the protection features, is a CP006WD.
