Page 1: Corsair CX 648 F RGB in the test – good all-round power supply with ARGB interface

Corsair has with the CX-F RGB Series recently added an interesting range of mid-range power supplies that can come up with RGB lighting for the fan. That doesn’t sound particularly exciting, but the RGB lighting can not only be controlled “stand-alone” via a button, but also via an ARGB or iCUE interface, making it easy to integrate into the lighting concept of the overall system. With 80 PLUS bronze and fully modular cable management, it is also solidly equipped, which is why we choose the middle CX 650 – Have a closer look at F RGB.

The highlight of the CX-F RGB Series are certainly the features in the RGB area, for the simple fact that there are not (yet) many power supplies whose RGB lighting can be controlled externally via an interface. Last year we had such a model from the Thermaltake Toughpower PF1 ARGB 750 W Platinum High-end segment in the test.

If the system should only shine in a single color, then that doesn’t matter, but as soon as dynamic effects are to be used, integration into a control system such as Aura & Co. or Corsairs iCUE is essential. The Corsairs CX-F RGB Series certainly has a good stand here, especially since it can be assumed that both the technical and optical coordination with Corsairs RGB products will be good.

The CX-F RGB Series comprises three models with 550 W, 650 W and 750 W, each in a black and white version are available. From a technical point of view, our test pattern CX 650 F-RGB does not need to hide. The nowadays slightly below average 80 -PLUS bronze efficiency is certainly owed to the goal of keeping the price of the power supply within an attractive range, which is just under 85 Euro is definitely the case. And since the typical gaming system shimmering in RGB colors is also not 20 / 7 is running, is 80 PLUS bronze quite sufficient.

The CX 650 F RGB offers modern technology with DC-DC converters, is equipped with good quality capacitors and comes with a solid 5 year manufacturer’s guarantee. On the equipment side, it can boast a fully modular cable management with black ribbon cables and good connection options. Corsair also promises quiet operation of the integrated 140 – mm – RGB fan.

The price is the CX 650 F RGB with approx. 85 Euro street price not badly set up if there is interest in RGB capabilities. The smaller CX 550 F RGB with 550 W is currently for approx. 65 Euro to find that CX 750 F RGB for just above 86 Euro.
