It's been a long journey, but now the time has come: AMPINEL will be available to order in our shop on Monday, February 9, 2026, from 4 p.m. (CET / UTC+1) onwards.

Anyone who has followed developments is aware that there was a delay of around three months at the end. The reason for this is that AMPINEL operates at the cutting edge of measurement technology in many areas, and we want to deliver a product that works reliably and offers real additional value.

Due to the significantly expanded range of functions and the additional development costs associated with this, a price adjustment was also necessary. AMPINEL will go on sale at a price of EUR 99.90 (incl. 19% VAT).



AMPINEL is a power supply balancer for graphics cards with 12V-2x6 power connector, explicitly developed and released for NVIDIA RTX 4000 and RTX 5000 series cards. Release for AMD cards is currently being worked on and will communicated after successful validation.

AMPINEL works in a much more complex way than other solutions on the market. As a balancer, AMPINEL actively regulates the current on the individual rails, thereby reducing power losses at the connector. This may sound simple at first, but requires highly complex measurement algorithms, as AMPINEL does not simply equalize the current on all lines, but also takes heat generation at the connector into account. To do this, AMPINEL determines the quality of the connections, which is only possible through a complex analysis of the measurement data. Since the power consumption of graphics cards is highly dynamic and the current may change significantly in the range of microseconds, this has been one of the most difficult tasks in our development.

By evaluating the measurement data, AMPINEL can determine not only the contact resistance to the graphics card, but also in the path from the power supply to AMPINEL. The results are visualized in the aquasuite software, where different colors represent resistances in a schematic of the corresponding connectors, thus enabling easy diagnosis in the event of problematic contact resistances.



To enable optimum protection of the graphics card, the following objectives have been defined for the AMPINEL control logic:

1. The current must not exceed 9.2 A at any of the contacts (plus 5% control tolerance).
2. The total power loss at the connector should be minimized respecting this specification; the current is then balanced accordingly.
3. The power loss of individual contacts must not exceed a specified power rating.
4. The maximum power loss at the balancer must not be exceeded.
5. The temperatures at both connectors and at the balancer are monitored.

The integrated monitoring is extremely comprehensive and includes voltage and current measurement on all 6 channels.



The multi-level alarm management system is also comprehensive. This enables a finely graded response to unwanted situations.



In addition to visual and audible alarms, a wide range of actions can be defined. These range from pop-up messages to automatic termination of software that causes a high GPU load, sending of definable hotkeys, shutdown of the PC, switching of alarm outputs, switching off of the Sense lines, and hard shutdown of the graphics card power supply via AMPINEL.
Overall, the alarm system is controlled in 8 stages, for which the corresponding escalation levels can be defined.

The balancer can be limited to a control range of 0-100%. If you only want to use the alarm functions in the event of an alarm and do not want to use balancing, you can configure the control range to 0%.

The maximum power reported by the power supply via the Sense contacts can optionally be reduced by AMPINEL to put the graphics card into a more economical operating mode. AMPINEL supports power levels of 600 watts and 450 watts.



AMPINEL has an OLED display, a button, and multicolor lighting. The data to be shown on the display can be selected in aquasuite. Several alternating views are possible. Currents, voltages, and other AMPINEL measurements are quickly visualized and can assist in troubleshooting the cable.
In addition, a variety of PC hardware data can also be displayed on the AMPINEL display, and text and graphic logos can be customized according to your preferences.

The integrated lighting can display a wide range of measurement data, for example, the current power consumption of the graphics card can be visualized as a colored bar graph.



Of course, all other aquasuite functions can also be used with AMPINEL. These include, for example, extensive logging and evaluation options, the creation of almost any function in the Playground, and individually customizable overview pages.



We are delighted to have finally brought this project to a successful completion and look forward to receiving your feedback. An initial test was already published by igor’sLAB in October.

In the test, AMPINEL achieved a sensational 5/5 stars and the Editor's Choice award. The hardware has not been changed since the test, but the software and firmware have been significantly improved once again. We will continue to take your feedback into account and incorporate it into our product maintenance in the future.

AMPINEL is available in two different configurations: Type A and type B. The difference is the connector orientation of the 12V-2x6 connector for the graphics card, corresponding to the different assembly variants of the graphics card manufacturers. Please select the variant that matches your graphics card; the connector orientation cannot be changed.
It is important to connect AMPINEL directly to the graphics card. Do not use extension cables or adapters between AMPINEL and the graphics card. This is the only way to measure the relevant contact resistances on the graphics card!



The following technical drawings can be used to check whether the adapter can be installed in your setup without restrictions. The drawing is to scale and can also be printed out for better evaluation. Please ensure that the actual size is used in the print settings without rescaling.

I assume 5090 SUPRIM is TYPE A?

Based on this photo, the connector is type B but it will NOT fit because of that "bridge" from the Backplate! The area overlaps with the AMPINEL. This would only work if you removed a piece of the backplate.
