MSI MPG A850GF 850W Power Supply Review

MSI MPG A850GF Power Supply

MicroStar International Co Ltd (MSI) is a company best known and covered for its motherboards and video cards. Since their founding, though they have become a huge manufacturer and supplier of a wide range of products including notebooks, video cards, motherboards, various consumer electronics, and barebones systems.

However, in the wings, the company has also been branding a few power supplies that are available in retail and e-tail. Today, we will be looking at one of what MSI is calling their first power supplies (it isn’t…….) in the guise of the MPG A850GF. This power supply is 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 it used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as it has a fairly high level of vertical integration providing transformers all the way up to its well designed independently regulated SMPS. Recently, however, CWT has begun stretching out and is providing OEM services for a number of brands as today’s unit demonstrates.

MPG? Ok, I’ll Pour Gas Into It If You Tell Me Too

The MSI MPG A850GF is the first power supply we have seen from MSI at TheFPSReview as well as one of the few they have ever produced. Contrary to the advertising that would make you think that these MPG units are the first power supplies that MSI has produced they are not the first. Prior to this, about 14 years ago, MSI had a series of Turbostream power supplies that were absolute trash. This is in spite of the fact that MSI has been a major industry player in the enthusiast realm for a very long time before that abortive effort.

Given the fact that they have waited this long to step up their game and reenter the PSU market makes us hope that they have been working extraordinarily diligently in order to dot all their “I’s” and cross all of their “T’s” unlike the last time. However, before we get too antsy, and jump the gun by moving on to see how the MSI A850GF does, and what it costs, let’s first see what MSI has to say about this unit:

  • Supports the NVIDIA GeForce RTX™ 30 Series GPUs
  • Full modular cable design
  • Flat cable equipment
  • 10-year warranty
  • 80 Plus Gold certified for high efficiency
  • 100% all Japanese 105oC capacitor
  • Active PFC design
  • Industrial level protection with OVP,OCP,OPP,OTP, SCP,UVP
  • LLC Half Bridge Topology with DC-DC module design

Let’s move on now and see what we can expect when a user purchases the MSI A850GF power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
