Corsair CX-M Series 650 W Review – Great Value

Introduction
There are only a few Corsair CX-M reviews since they are budget units, so I thought to do something about it. Corsair upgraded all CX-M units and used their new design with triangular-shaped perforations on the fan and exhaust grilles. The exterior readily distinguishes the new from the old. Today, I will look at the CX650M with enough power to support a mid-level system. The CX650M has the Bronze 80 PLUS and Cybenetics Silver efficiency ratings, as well as the Standard++ Cybenetics noise rating, which is pretty good for its efficiency. The fan uses a rifle bearing, and the 5-year warranty is long enough for a $70 PSU. Lastly, at only 140 mm deep, this compact PSU won’t give you any headaches during installation despite its two affixed cables.
The previous line included a 850 W model, but the new one only goes up to 750 W across three unit in total, starting at 550 W maximum power output. All of these feature a semi-modular cable design to lower the production cost and use less advanced platforms than the CX line, which is too advanced for “mere” Bronze efficiency.
