Corsair CX750 750W Power Supply Review

The Corsair CX750 is, "An ideal choice for value-conscious system builders and upgraders." So when saving a few bucks and buying a Corsair Bronze rated power supply do you still get a PSU that can deliver clean power under load? We are hoping that fewer bells and whistles does not equate to less quality in the wattage department.


Corsair is known in enthusiast circles as a supplier of high performance memory and has risen to become one of the most talked about power supply brands around. Corsair was initially able to establish a presence in such a short time through the use of quality OEM’s (Seasonic and CWT), rigorous standards, and excellent support. Since its entrance into the PSU field, it has established a number of lines of power supplies of varying quality to address (and overlap) just about every market segment. Today, we have the first unit we have seen from Corsair's CX line; the CX750 (CP-9020015-NA). This unit is once more produced in conjunction with CWT.

Channel Well Technology (CWT) was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, Thermaltake, Xigmatek, and Corsair. While most familiar to our US users from when they used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as they have a fairly high level of vertical integration providing transformers all the way up to its well designed independently regulated SMPS. However, CWT has been stretching out over the last few years and they are providing OEM services for a number of brands as today’s unit demonstrates.

It's the Hobie Cat of the Fleet

The Corsair CX750 is the largest member of the CX series of power supplies from Corsair. Over the years, we have seen a few lower end power supplies from Corsair and until recently those products have still been good options for users. However, over the last few years much if not all of the lead Corsair had established over other brands in every product segment we have seen has wasted away as their product lines have stagnated, reverted, or just been botched relaunches of products for no apparent reason. However, none of the products we have seen have been from an entry level product like the CX series (one of only three series we have not seen from Corsair), though the less than stellar CS550M is very close. So, how this unit will perform relative to the competition is certainly up for grabs today as history is not kind but this product is a bit of an unknown. Before moving on to see if this ship has started to right the course, let’s see what Corsair expects from this ship:

CX Series PC power supplies are an excellent choice for basic system builds and desktop PC computer upgrades. CX Series PSUs are available in a variety of power configurations, and include features that are normally found only on premium power supplies.

Moving on let’s see what we can expect when a user purchases the Corsair CX750 power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
