Specifications

Efficiency is Gold, and while the VSM750 unfortunately features a semi-modular cabling design with many native cables, CM says it to be Haswell ready. The operational temperature at up to which it can deliver its full power continuously is restricted to 40°C although the ATX spec recommends 50°C. However, following our tough methodology, we will push it above 45°C just to see how it fares. Since its protection features include OTP (Over Temperature Protection), doing so won't endanger the unit.

The cooling fan only has a diameter of 120 mm because a larger variant wouldn't have fit into the small enclosure, and it uses ball-bearings, which increases its durability. CM also provides a five year warranty, which is long enough for the category, and while its price may look high, CM made a point of using nothing but Japanese caps this time around.


The single +12V rail is powerful enough for two strong VGAs, and the minor rails are sufficiency powerful for a modern system. The 5VSB rail has the standard capacity for a contemporary low- or mid-level PSU, which is usually enough.

Cables & Connectors, Power Distribution

There are four PCIe and one EPS connector. We think that CM should be more generous by providing another EPS connector. We would also like to see less native cables as all PCIe cables should be modular, or at least the second pair. The main ATX and EPS cables are long enough for a normally sized case, but you might run into problems with larger full-tower cases. The distance between peripheral connectors is spot on, but some of you may prefer its SATA connectors to be a little closer together (e.g., 11-12 cm) as HDDs are usually installed close to one another. All cables also use 18AWG wires, which is the standard the ATX spec recommends.

Since this PSU features a single +12V rail, we have nothing to comment on when it comes time to talk about its power distribution.
