Fully Wired Connectivity


Modular Cabling System

On the CX850M PSU the peripheral power cables aren’t hard-wired to the power supply, you can connect only the cables you need for your exact configuration of PCI-E cards and storage devices. The rest of the cables stay in the box, and not in your PC’s case where they can add to the clutter and interfere with airflow.

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

850W Corsair CX850M, Hybrid Modular, 80PLUS Bronze, SLI/CrossFire, Single Rail, 70A, 120mm Fan, ATX PSU is rated 4.0 out of 5 by 2.
Rated 3 out of 5 by from Introduced me to coil whine As the title states this opened my eyes as to why you shouldn't skimp on your power supply. I hear that it is perfectly safe but the coil whine is so bad that I have forked out another £180 for a decent EVGA PSU as the noise is making me worry that it is going to brick my pc any minute.
Date published: 2017-12-14
Rated 5 out of 5 by from Decent There isn't much I can say about a PSU unless I have used it for a considerable amount of years without power loss by which time a review would be pointless as a new line of PSU's would be on the market. My friend has had the 750w version for 2 - 3 years and is still going strong. Other than this, all I can say is that the noise is practically non-existent and that the cabling is pretty decent in terms of both build quality and that you can power 2 graphics cards with a single cable that has 2 plugs. As always scan is a decent company to buy parts from both online and in-store.
