Cooler Master V Series 1000W PSU Review

Cooler Master certainly made the right decision when they partnered up with Seasonic for their new high end power supplies. The V Series 1000W unit is an exceptionally good power supply, based around the class leading Seasonic KM3 high end design.

First impressions are very positive. Cooler Master protect the power supply in a soft, high grade felt bag and they are using high grade 18AWG flat cables, perfect for cable management and maximising air flow. We think the modular backplate is well laid out and all the peripheral cables are vertically mounted into the V Series to ease installation.

The chassis paintwork is deep and very resistant to damage which can often occur to a lesser finish after installing into a system case.

Technically the V Series 1000W power supply is rock solid and exhibits no weaknesses. Ripple suppression is class leading and well within the industry tolerance guidelines. Our sample peaked at just under 93 percent efficiency at 50 percent load, a fantastic result.

Cooler Master have adopted a very high grade fan inside the V Series 1000W supply which spins very slowly until the last 15% of load. It emits very low levels of noise across the load range and ensures that the components inside have adequate airflow. The fan profile has clearly been optimised for low noise levels, which will please many enthusiast users.

Under our stress test, the unit also delivered almost 1,200watts of power before shutting off safely, so there is clearly some additional headroom above the rated 1,000watts. A good indication of the quality components used by Seasonic.

At time of press we have no indication of UK cost, but we would expect it to be competitively priced in the high end sector.


  • excellent build quality.
  • delivered almost 1,200Watts before shutting off.
  • high grade components inside.
  • efficient.
  • low noise.
  • high grade cabling.
  • 100% Haswell compatible.
  • 5 year warranty.


  • a few more SATA and Molex cables would be useful.
  • stiff competition in this sector.

Kitguru says: As good as its gets in the high end.

KitGuru Games: Xbox Series X – A Year in Review

It has been roughly a full calendar year since I first picked up an Xbox Series X and with PC upgrades hitting all-time high prices, I've spent most of 2021 as a console gamer, primarily playing on Xbox. With Year-One down, it is time to take a look back at the first year of 'next-gen' and whether or not it was worth upgrading right from the jump.
