## Questions & Answers

**Q: Can I use this with my Surface Book?**
A: Unfortunately, Surface Book is not with any Thunderbolt chip. So it cannot be used.

**Q: Can 3.5 inch hdd fit inside**
A: Yes and no. 3.5 can not be mounted, only 2.5 or ssd size can be mounted as they come with a mounting plate but a 3.5 hard drive can fit in the unit if it is not mounted. wish mantiz would put a mounting bracket made for 3.5in HDD.

**Q: Can i use this with my macbook pro closed? i've heard that other egpus used with macs require that the lid/screen be open.**
A: If you upgrade to the latest public beta, the macOS 10.13.4 you can use it as a clamshell, meaning the macbook lid closed and just using the external monitor connected to the eGPU. However, this work better for natively supported GPU cards, meaning AMD RX560-580 and the new VEGA cards. I'm currently using my Macbook Pro 2017 15" with a Mantiz Venus + AMD Radeon Pro VEGA Frontier Edition in clamshell mode.

**Q: Can this work as a "docking station" without gpu? (want to get gpu later)**
A: Yes. No problem, the SSD/USB/LAN will be functional even without the GPU inside.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fantastic quality and does exactly what you need.... Well!
*by B***I on October 21, 2020*

First time diving into an eGPU world and I'm so glad I went for the Mantiz!! the performance is better than expected for n external solution. I have an ssd inside to store all my games as I run Linux and windows so when I need to dual boot into windows for work but have time for a game I can simply use the linked drive to play rather than 2 copies of everything. My average transfer speed between my SSD and Linux is 215MB/s (Not megabits) and I haven't pushed the GPU yet as I'll be upgrading to a 5700xt after the new Radeon launch and prices drop lol.Windows is full plug and play with this unit, simply plug it in and give it up to 20 seconds depending on what you're doing and it'll fire up the external monitor and your ready to rock. Linux requires a log out of reboot depending on your distro and setup... I'm still new at this but technically Fedora, Ubuntu, KDE neon and Manjaro work pretty easily but once you config it boot up can be a bit faster. Hopefully TB support at a plug and play level for eGPU's makes it to the kernel soon but I works fine as is apart from a reboot.I've been in touch with Mantiz in regards to the PSU noise and after I pulled it apart we do agree that the fan "may" be a tad noisy/scratchy kind of sound but they were happily going to swap it out for me, I had already purchased a Thermaltake PSU to replace the original so I didn't take them up on the offer but they are very fast to respond on Facebook messenger so get in touch with them if you need anything or have any issues.If you're like me and tossing up between the branded but older Razer core enclosures or the Akito's... don't! This thing is very well built, faster with the 2 TB controllers and my SSD speed confirm that. Only thing I'd do if you're a quiet PC person like me is grab (as I did) 2 Noctua 120mm (1x 3 pin for PSU & 1x4 pin PWM for the enclosure) and if your GPU has zero rpm fans you're laughing as it's DEAD silent!!!That's my review, I highly recommend and if you're on the fence I can assure you it's worth the chance.(Also I had to order on Amazon US as I'm from Australia but they don't come up on the Aus Amazon for some reason... even with that the shipping was super fast and I still paid less than a Razor core in Aus so winner winner)

### ⭐ terrible eGPU
*by J***L on December 24, 2020*

edit: this thing is awful. it constantly drops video or audio. I have to repeatedly plug in/out to get it back on. Tried on two different laptops to make sure it was the eGPU. It looks great on paper but doesn't work.This thing is awesome. For this price, it's definitely the best option.I'm using it with a GPD Win Max and a Vega 64. No issues with anything working and it was pretty much plug and play. Two monitors, keyboard/mouse, headset, ethernet and sound are all hooked up to the EGPU. I only have to plug in one cord to fire everything up.My only gripe is the lack of USB ports. Only having two in the back is silly. I only need one in front (spare USB/headset) but this gives three upfront. I had to plug my mouse in front which looks bad.I also added a 3.5" Sata drive and to my surprise it actually fit. It's not designed to hold it but it does lay in there nicely.

### ⭐⭐⭐⭐ Great!
*by H***N on January 6, 2018*

I use this with my 2017 MacBook Pro. It works well enough in both MacOS and Windows.MacOS experience:In Mac, it works right out of the box. No need to install drivers. No fuss. Mac automatically detects the device and immediately starts working. One thing to note is that HDMI output seems to be limited to 30hz refresh rate. This may be something that can be updated later in software. The display port can use the maximum refresh rate of my monitor.Win10 experience:My experience on Windows 10 didn't go as smoothly. I eventually got it working, but it wasn't without a hard fought battles. Getting Win10 to detect the eGPU was hit or miss. It took a few tries for Windows to install the proper PCIe, USB3, and Thunderbolt 3 drivers. A few times, it didn't recognise the hardware correctly and registered it as a completely different device. Once the basic drivers were installed it started working properly, but then came the trouble of installing the GPU drivers (Radeon RX 580 8GB) - I could not get the Radeon software to detect that I had a compatible graphics card installed. Instead, I had to find stand alone drivers and install it with using the INF file. Once everything was installed, it would work pretty flawlessly until I connect or disconnect a peripheral from the USB ports on the Mantiz or form the USB-C ports on the MacBook. Doing so causes the entire system to freeze. This was all resolved after running Windows update.To be fair, the issues listed for Win10 and the refresh rate issue with MacOS is probably not unique to this eGPU since this is new technology. It will probably improve in time with operating system updates. Other than that, the power supply as enough juice to power any GPU and hard drive. Hardware installation was pretty straight forward. There are enough connectors in the unit for all types of power requirements. The fans are a little loud but those are replaceable.I would give it 5 starts, but getting it to work was kind of a pain.
