      "The V-Series gives Cooler Master a PSU line that joins the ranks of the elite and is a perfect complement to the rest of their line-up. Performance and build quality of the V850 are top notch, and definitely among the best we have ever seen. The all black cable system has an excellent look, and the flat modular design makes for easy cable routing, though the layout may cause additional cables to be needed. Frankly, the need for an extra cable is a small price to pay for top notch power delivery and efficiency, and that is exactly what the V850 gives you. The V850 takes home a Hi Tech Legion Editor’s Choice Award and is highly recommended."

      "Coolermaster has done nearly everything right with the new V series units. They picked a supplier who is obviously on top of the world right now, they've marketed an outstanding platform conservatively when it comes to the efficiency certifications, and they've pretty much tried as hard as they can to toss something my way as close to perfection as possible. And it paid off. Look up there... see how close they came to tens across the board? Only a small handful of units have ever gotten closer than this. Yes sir, this one's an easy recommendation for sure. "

      "The V850 sports all of the same features and the performance is very close to that of the V1000 in Voltage regulation, DC output quality and efficiency, which is great to see."

      "This is a very good PSU.

      CoolerMaster has said that they were stepping things up in the PSU game, and if this V850 is any indication they are doing exactly that.

      It looks great, I especially like the rounded metal around the modular connectors instead of the standard sharp edges.

      It's quiet up until high heat high load, which is nice. At full tilt the fan isn't the quietest, but it's not the noisiest either. If you can put that much of a load on it you have a few GPUs running full tilt as well, not quiet."

      "In terms of performance, the V Series units finished spectacularly well, with nominal movement on the rails in our voltage regulation testing, while the ripple results were also excellent. Seasonic is the OEM here, and they typically produce some of the very best power supplies on the market, and it’s no different with the V Series."

      "Over all performance of V850 is very much solid and very quiet. The Ultra Silent Long Life 135mm fan definitely does its job. We have spent roughly two weeks working with V850 and haven't experienced any problems or glitches in power. Full modular cable design here is great. Use cables you need, none that you don't."
