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, Corsair brings us a new revision to and old classic from their RMx line; the RM750x (CP-9020092-NA) which we will call the RM750x (2018) due to it being the second revision of this unit. This unit is produced in conjunction with Great Wall.
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, Enermax, 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.
Today's Corsair RM750x (2018) is another product refresh from Corsair similar to what we saw from the recent TX750M. However, in this case, we never did see the original RM750x only the RM750. Now, with so many power supply product lines (9 as a matter of fact) Corsair's saturation in the market makes it kind of tough to figure out where each of these products is aimed at and if that previous RM750 is any kind of indication of where the RMX line is supposed to place. That said, when we check out Corsair's PSU landing page, these units are listed under the heading "MODULAR, QUIET PERFORMANCE PSU" which is the second lowest rung on the ladder. Therefore, these seem to be mainstream kind of products but at the same time they say performance. Then, also listed there is the TXM line which we recently saw in the guise of the TX750M and that was a mainstream product. That means that not only will this units performance against other brands be of interest today but also its performance when compared to its stable mate. Before moving on to that comparison though, let us see what Corsair has to say about this unit specifically:
Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set. Built with all Japanese 105C capacitors, they’re a great choice for high performance PCs where reliability is essential. 80 PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. And, the fully modular DC cables make builds and upgrades easy, with clean, great-looking results.
Moving on let’s see what we can expect when a user purchases the Corsair RM750x power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
