Review: Nice! - Working great!
Review: Not work with Lenovo T430 - The product works fine itself, but didn't work with my Lenovo T430 laptop. The computer cannot detect the external GPU with the product. I cannot disable built in display in BIOS by following the instruction. Probably the product is better for experienced computer technician, but not good for general computer users.

## Questions & Answers

**Q: What version exp gdc (v8.0, 8.4d, or 8.5c) is this? ? listing this detail helps us buyers know what we are getting.**
A: Hi, It is 8.5 version

**Q: What version of mini pci-e i t use, 2.0 3.0?**
A: 2.0

**Q: Does this adapter have a power on / power off switch where the unit can be turned on before attaching to laptop at the pci express card slot?**
A: No power on/off button on the device.  It will be turned on/off with the laptop automatically after connected via express card slot.
Anyway, the device doesn't work with my laptop. I am not able to setup the device appropriately with my laptop.

**Q: Do i have to strictly power the gpu from the output 8-pin pcie connector of this gdc or i can directly connect gpu from the atx power supply?**
A: If the GPU has a PCIe Power Connector, it requires more current than the PCIe slot can provide.  Since this device requires a dedicated ATX power supply, if that power supply has a PCIe power connector, connect the GPU power to that.  It will switch on and off with the adaptor and card.

### ⭐⭐⭐ Review
*by J***N on February 8, 2025*

English: "To be honest, I used it alongside the other adapter that burned out, so I can’t say much more. But what I can say is that these docks are usually way too expensive for how limited they are in bandwidth and overall quality. Even on AliExpress, they still feel overpriced for what they offer. I don’t know, I have mixed feelings about it." Spanish: "Si soy sincero, lo usé junto con el otro adaptador que se me quemó, así que no puedo decir mucho más. Pero lo que sí puedo asegurar es que estos docks suelen costar demasiado para lo limitados que están en ancho de banda y la calidad que tienen. Incluso en AliExpress siguen siendo caros para lo que ofrecen. No sé, me deja con sentimientos encontrados."
