Cooler Master V750i Gold PSU Review

The Cooler Master V750i is an expensive mid-capacity PSU, offering high efficiency and low noise output. It allows you to set-up your own fan speed profiles, though the provided software, since it includes a digital link through which it can “talk” to your system’s mainboard. Are all above enough to justify an over 170 dollar price? Read the full review to find this out! 

The Cooler Master V750i is included in my best ATX v3.0 & PCIe 5.0 PSU picks article.

I have already reviewed the Cooler Master V850i, so that I couldn’t pass on its smaller brother, with 750W max power. The OEM of both units is Chicony Power, one of the largest PSU manufacturers. Like the V850i, the V750i is advertised as a semi-digital power supply. However, this is inaccurate since the digital circuits are restricted to the digital interface connecting the PSU to the system’s mainboard, mainly used for monitoring purposes. The only control option is for setting custom fan curves.

The V750i is ATX v3.0 and PCIe 5.0 ready, meaning that it can withstand power excursions up to 200% of its maximum power, or 1500W. It is equipped with a 12+4 pin connector, which is set for up to 300W max power, while in the V850i, the same connector can deliver up to 450W. This means that the V750i is not ideal for power-hungry GPUs like the NVIDIA RTX 4090.

The price difference between the V750i and V850i is slight, at only 12 dollars, making me wonder why someone should not go directly for the latter to have more headroom for future upgrades. At $173, the V750i is anything but affordable, so CM tries to advertise it as semi-digital to justify the increased price.

  1. Hi Aris,

    I noticed in the article on Best ATX 3.X PSU (Best ATX v3.x & PCIe 5.x Ready PSU Picks 2024 – Hardware Busters) that the v750i wasn’t listed in the 750w category. What is the reason for this despite it being better than the TT GF3 and PF3 750w on overall performance in both 115 and 230 volts AC?

    Many Thanks 🙂

    1. Hi! I am confused with this PSU. I cannot find it on Amazon. Actually, I got a kickback from the affiliate link that I used that this product is no longer available. This is why I removed it.

      1. Thanks for the reply Aris. That’s interesting, where I am it’s currently available for just under 100usd (after conversion) so I’m thinking of buying it for a 750w build. Would it still be the best pick today (assuming it’s available)? 🙂

  2. These Cybenectics/80 Plus gold-rates psus are really good performance-wise. Price-peformance is even better.
    What I don’t like is the noise. 23 dbA is very audible. No clue if you testers or people from cybenetics etc. have damaged hearing or are partly deaf or so, but I can clearly hear my 18 dbA rated psu from 2 meters away in a somewhat silent room. ;=)
    You people state that 20 dbA or so is not audible anymore from 1 m distance, but I can cleary hear it. No, I I’m not a bat 🙂

    – Does this one has any coil whine?
    – Is it compatible with future 2x 8pin-to-12+4pin cables, for enhanced protection? After all besides the 12VHPWR socket, it has multiple 2x 8-pin sockets.

    1. if you can hear so well, then you are probably Batman 😀
      I didn’t notice any coil whine during testing, but this depends on the system that you will hook the PSU
      I think that by now most brands will use the new 12+4 pin socket, and not the older one.

      1. I don’t understand it myself. Yes I can still hear frequencies up to 18 – 19 kHz and very quiet sounds (whispers, and a pin needle falling on the floor from few meters away) but I thought the test equipment at Cybenetics and 80 Plus is better than any human hearing.
        So how come Seasonic states mine Titanium TX psu is “literally inaudible, at the threshhold of human hearing”, and here I can clearly hear the fans start spinning from 2 – 3 meters away at only 300 watts load?!
        I know the differences between dB and dBA and that there are differnces in anechoic chambers, but I can’t have ears better than the most sensitive equipment.
        It’s the same with people testing graphic cards and stating “32 dBA fan spinning is not audible anymore inside a case, from 50 cm away”, and here I can still hear it from 4 meters away.

        Btw. I asked a company representative from a known psu manufacturer (you people here test their products all the time) who sells in Europe, when their updated ATX 3.1 psu with the 12V-2×6 socket will arrive, and she stated “starting from Q1 2024”.
        Yes, the 12+4 pin socket is fine, the burning cable and adapters were only due to users not being attentive, not fully plugging the adapter in or bending way to much.

        1. I will tell you one little secret, the best noise tool is the human ear, because it can go down to 0 dBA, while the best mic in the world right now, has a low limit at 6 dBA. Now if you are able to catch super low frequencies or super high ones, you have cat’s hearing!

          Also 80 P doesn’t do noise testing, at all. Only Cyben does.

          ps. 32 dBA is not quiet even from 1 meter away.
