This is the second generation eGPU enclosure from Mantiz to replace the Venus. The overall dimensions have grown to accommodate the larger ATX power supply. In short, Mantiz is clearly aiming at #1 place Razer (Core X/Chroma). This unboxing doesn't have any photos of the box because it was in bad shape.

The package arrived from Hong Kong through UPS. It took a serious beating. The shipping label was soaking wet and there were multiple damaged areas on the box. Fortunately the only injury to the enclosure was a dent to one of the vent grilles. I was able to push/pop it back in place. The Mantiz Saturn Pro comes with two small accessories boxes, one containing a power cable and the other containing 4x Phillips screws for 2.5" SATA drive and a .7m Thunderbolt 3 cable.

Unlike the Venus, the Mantiz Saturn Pro has much easier internal component access. The inner cage slides rearwards once you remove the large thumb screw on top. There are two L-shaped hooks on the rear fascia to pull on. It's an unusual design but works well without being a handle that may block the graphics card ports. I would personally remove these hooks to make it look cleaner. I could easily pull the inner cage through the area by the GPU mounting bracket.

Build quality is one of the best eGPU enclosures I've used. The brushed aluminum shell is light but very solid. I was amazed the left-sided vent grille withstood that shipping damage and went back to form with minimal repair effort. There's a large rubber pad on the bottom. This is very similar to the Razer Core X/Chroma. Mantiz also has its logo on the front fascia with this new eGPU enclosure. I don't mind it and think the overall design is very attractive. The brushed aluminum texture reminds me of the RX Vega reference cards so I installed my Vega 64 LC to test.

As you could see there's a bunch of cables to manage. I have not measured the dimensions but it seems smaller than the Core X/Chroma. Component placement are very similar between them. The only exception is expansion ports on the front of Saturn Pro whereas the Core X Chroma has a lighting strip. There's no RGB in this Mantiz enclosure just like the Venus - a clean, professional look.

Mantiz improved on an already well-equipped offering (5x USB, 1x SATA, and 1x Ethernet) by adding an SD card reader, hosted on a secondary Alpine Ridge Thunderbolt 3 controller. This is a very welcome expansion port for Mac and ultrabook users. I also like the PSU fan placement and the large size (120mm). The enclosure cooling fan is also 120mm and share the same metal bracket with the PSU. It can be used for a 120mm radiator in most AIO liquid cooled GPUs. My RX Vega 64 LC fitted perfectly but required a lot of cable management to make sure they don't touch the fan blade.

Mantiz studied the Core X/Chroma closely and made a similar sliding base for its Saturn Pro. It works great and has very little wiggle room compared to the Razer enclosures. What Mantiz has outdone Razer is the PSU. It's a 750W unit that provides 100W upstream Power Delivery and 600W to the graphics card. There are also 3x 6+2-pin PCIe power cables so that the most monstrous of graphics cards won't trouble this PSU.

Other refinements I noticed are the metal shield on the Thunderbolt 3 mainboard, fan-off mode on the PSU during light load, and much easier access to the SATA drive. The SATA 2.5" drive metal bracket sits on top of the enclosure cooling fan mount and can be removed. In my installation of the RX Vega 64 LC, I removed it and relocated the SSD to sit at the bottom in the space between mainboard and front expansion board.

The sad news is my RX Vega 64 LC is likely dead. I found a leak on the pump a while back and tried to patch it after not able to find a replacement pump. The fan would run full blast when it's powered on but macOS cannot detect it was a GPU. Therefore I can only test with Radeon VII and other air cooled Radeon cards for now. Let me know if you have any questions on this new Mantiz Saturn Pro enclosure.

@itsage, a clean shot of the rear of the enclosure to see port placements would be cool (you have one from the top tho). How’s the sliding mechanism (smooth)? The only sliding mechanism I’ve used is on the Akito Node and that was horrendous.

@mac_editor, Will do. It's much smoother compared to the AKiTiO Node (plastic rails vs metal on metal).

What does the controller board look like?

They still using the same one that used in Sonnet BB?

@jyin, I haven't torn it down to check the mainboard but definitely not the same. There are now two TB3 controllers and rear expansion ports are on the mainboard. Here are some screen captures in macOS.

SATA drive, Ethernet, and rear USB ports are on one USB hub. SD card reader and front USB ports are on the other.

@mac_editor, Here's a couple pictures of the rear ports. Sorry it's hard to see the very tight space between top of the PSU and the shell.

Nice review, thanks. It's nice to see more and more manufacturers are offering true 1 cable solutions. Is this going to be available in Europe?

I really like the look of this case compared to the Razer model, I've just brought a MacBook Pro 2020 and i'm looking for an EGPU to pair with it, ideally i would like a fairly quiet set up, at least better then a set up i had a few years ago (Aorus box 1070 & XPS 9550),the noise was to much! 

  • How is the fan noise on this?

 

  • Based on your testing is there an AMD card that runs quieter then the rest(mid tier)? 

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Curious to see how this performs with a USB hub connected to the USB ports on the back. Does it have the same issue as the Chroma, where the devices connected to the hub (and then to the enclosure) randomly disconnect?

@mrcat, It should be available globally soon is what I heard. We may try a group buy again for forum members.

@daniel_obrien Both the enclosure fan and PSU fan are 120mm so they're are relatively quiet. The PSU fan has fan-off mode during light load so it's not running all the time. Generally speaking, GPU with massive cooler and multiple large fans are quieter.

@fraannk I've used several dual-TB3-controller eGPU enclosures. The key to reliable USB peripherals through the secondary TB3 controller is to not connect any USB hubs to the expansion USB ports. This arrangement replicates the original situation with single-TB3-controller eGPU enclosures. There are 5x USB ports on this Mantiz Saturn Pro as well as SATA drive, Ethernet, and SD Card reader. Plenty of expansion as is so USB hub should be avoided.
