Powenetics V2 – Power Measurements Device – Review

Epilogue & How To Get One!

I expect the Powenetics V2 to soon become the default tool for accurately measuring sustained power output and spikes. The 1 ms polling rate is to get all nasty power spikes from CPUs and GPUs, which can be extreme if I consider the strict requirements of the ATX v3.0 and PCIe 5.0 standards. Its price looks high, but I firmly believe that it is decent given the amount of work we devoted to making it and the benefits that it will bring to its owners. Moreover, the production is small since I don’t expect a considerable demand, affecting the material cost. Finally, it would be best to keep in mind that lab equipment delivering similar results costs way more. If you try to take measurements with current clamps, you will need to get thirteen of them, calibrate them, and you will also need four oscilloscopes which you will have to sync. And still, you will only get Amperage information and not Voltage, so you won’t get the complete picture. To also have voltage readings, double the number of scopes and shunt resistors, making the measurement procedure even more expensive and complex. Lastly, to be able to sync Amperage and Volt readings from all scopes looks like an impossible feat, besides the EMI that can hugely alter the readings of the current clamps.

At this stage, Cybenetics is ready to receive pre-orders through an email to in**@cy********.com or through the hardware busters eshop. A Powenetics V2 kit costs 975€ without VAT, excluding shipping fees. For orders outside the EU, there is no VAT, and the same goes for business accounts within the EU. If you live outside the EU, you should also consider the importation fees at customs.

  1. Don’t get me wrong, the Powenetics V2 is surely a step in the right direction, but there is room for improvement:
    How long was this in development? I’m wondering as it only comes with 1 ATX12V, 3 EPS and 3 PCIe 6+2 whereas there are mainboards that come with 3 ATX12V or 4 EPS and MB + GPU combos that require 5 PCIe 6+2 sockets total and the Powenetics V2 does not look like it was designed to run more than one in parallel.
    Why no SATA or Molex sockets? Would have been nice to measure the whole computer.
    The low Amps rating on the 12VHPWR effectively means that there are scenarios where you need a custom made 2 12VHPWR to 1 12VHPWR adapter or another 4 PCIe 6+2 sockets.
    And why are the readings per sec fluctuating so heavily? It’s also more than just +- 50.
    Is there an ETA for a Powenetics V3 that addresses all these shortcomings?

    1. No worries, we are always open to suggestions.

      You can hook up as many Powenetics in parallel as you want, but the software is not ready yet!

      Powenetics is for desktop mainboards and not server ones. There are mainboards that can have numerous sockets yes, but Powenetics is for the 99% of users and not for the 0.1% of cases. If I installed so many sockets and sensors, then I would have to deal with increased cost and lower polling rates. That said, if there is demand, we might release a special version in the future.

      Low amp ratings on 12VHPWR? It can go up to 650W sustained and 1800W peaks.

      Readings per sec fluctuates +-50 but it is 1000 on average. USB and system limitations.

      V2 is already in its 4th revision. V3 will be at some point yes, but for the moment I don’t have anything in mind since I need to focus on other projects, too.

      About SATA and Molex, we didn’t put these because most users don’t use them anyway. Powenetics V1 has them and very few used them. The more the sensors the tougher is to find a proper MCU to handle all of them and keep a fast enough polling rate.

      Thank you for your suggestions!

  2. • How many Amps of sustained load can each of the PCIe 6+2 sockets/cables handle?
    • Is it easy to use two Powenetics V2 in parallel on systems that require more sockets than a single Powenetics V2 provides? This question aims mainly at the software as I don’t see why there should be a problem on the hardware side.

    1. 12VHPWR can handle up to 55A sustained and PCIe 6+2 are good to go at up to 21A sustained, these at room temperature and not at high temps.

      You can but you need special software. For the moment the software is only for a single powenetics board. In Computex one board handled four RTX 4090 through special cables.

  3. hello, did you have a corrspending email for contact with, I would like to know the details(including the stuff in v2 kit and procedures, and any others) and assess if it would be a fit for my lab, also how to order(the order page is written in a language Icouldn’t understand), thanks

  4. I came on the recommendation of Ronaldo from the TecLab channel (source of many useful and interesting information).

  5. ola os meus amigos do teclab nos indicou vocês o melhor canal de teste hardware impressionante o trabalho de vocês S2

  6. Isn’t a sustained load of 55A on a 12VHPWR connector kinda low considering that there are already graphic cards with OC BIOSes that allow them to draw 1000W?
