Ripple suppression is good, but not groundbreaking, on all rails.

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.
Greetings
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.
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.
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.
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 🙂
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.
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)? 🙂
at 100 USD is a good choice!
