Have you ever heard of a RTX 5060 of sem 8-Pin? If the answer is “no”, find out now: ZOTAC Magnus model can be powered only through the PCIe slot!
ZOTAC has presented an unusual technical solution for integrating a high-performance desktop graphics card into an extremely small space.
O mini PC Magnus, model EN275060TChas a GeForce RTX 5060 Up to 16 GB for desktop using a split PCI Express connection.
However, before let’s continue with additional detailscheck out a summary table with the main questions e answers of this topic:
| Question | Response |
|---|---|
| What did ZOTAC do differently with the Magnus mini PC? | ZOTAC divided the PCIe slot into two parts: one for data (PCIe 5.0 x8) and the other just to supply electrical power to the GPU, eliminating extra cables. |
| What video card does this system use? | The GeForce RTX 5060 Ti for desktop, 16 GB, in the compact model EN275060TC. |
| How does this hybrid interface work? | Half of the contacts (x8) take care of communication with the motherboard. The other half (x8) takes power directly from the PC power supply to the video card. |
| What is the main advantage of this design? | Allows you to place a powerful desktop GPU in a very small mini PC case (2.65L) without using external power connectors. |
| Does the GPU have full performance with this? | Yes. The PCIe 5.0 x8 connection has enough bandwidth, and the system delivers the 180W that the RTX 5060 Ti needs for maximum performance. |
| Does this design work with any graphics card? | No. It has a limit of around 200W. Stronger cards, like the RTX 5070 Ti, require a dedicated connector and are not compatible. |
| Is it possible to overclock? | The software allows you to increase power by 11%, but the small case’s cooling system does not maintain a constant 180W, limiting overclocking. |
| Who discovered the technical details? | The HKEPC website, which disassembled the ZOTAC Magnus and analyzed its motherboard. |
| Is there something similar on the market? | Not exactly. Solutions like the ASUS high power connector for BTF cards are different and do not integrate data and power into the same slot in this way. |
How ZOTAC’s Dual PCIe Interface Works
Contextualizing the information above, the configuration implemented by ZOTAC separates PCIe slot contacts into two distinct groups. According to the analysis of the site HKEPCone of the sets acts as the default data connection to the motherboard, operating on PCIe 5.0 x8.
The second set of contacts is dedicated exclusively to providing electrical power for the GPUfunctioning as a additional PCIe 5.0 x8 channel to conduct electricity.
This approach eliminates the need for traditional external power cables, such as power connectors. 8 or 12 pins.
Power is delivered directly from the mini PC source to the graphics card through the modified PCIe slot itself. The design allows the RTX 5060 Ti receive up to 180 wattssufficient energy for its complete operation.
Advantages and Limitations of Hybrid Design for Compact PCs
The solution maintains GPU performancebecause a PCIe 5.0 x8 connection offers enough bandwidth for the RTX 5060 Ti.
The tests of performanceor benchmarkscarried out with the product show results as expected for this video card model. This method can serve as a model for other compact PCs that use GPUs with moderate power consumption.
The effectiveness of the system has a clear power limit, estimated at around 200 watts. Therefore, the solution is not suitable for more powerful video cards.
O Model Magnus com a Geforce Rtx 5070 of thefor example, requires a dedicated 12V-2×6 connector and has a considerably larger case.
As mentioned above, other approaches on the market, such as high power connector for your BTF motherboardsalso do not replicate the integration achieved in this design of the ZOTAC.

RTX 5060 Ti without 8-pin? ZOTAC Magnus model can be powered only through the PCIe slot; conclusions
Although the software yes ZOTAC allow you to increase the GPU power limit up to 11% for overclockingthe cooling capacity of the Magnus mini PC imposes a practical constraint.
Analysis indicates that the cooling system is unable to keep the graphics card operating consistently at its maximum limit of 180 watts for prolonged periods.
Therefore, to conclude, we highlight that the performance gain via overclocking is limited by the 2.65 liter compact case thermal dissipation.
