Yet another quirk with the XPS 15 9570: when laptop is fully powered off (Windows -> Shut down, do not confuse with any other state), and TB3 cable connected to the Mantiz at shutdown time, the Mantiz seems to be kept powered on, as I hear the low frequency PSU fan sound (not the auxiliar fan noise though). If I unplug and replug TB3, the PSU comes back on for about 1-2s, Dell 9570's LED also shines for a moment (as if charging), and then powers off.

I believe this is one more of Dell's proprietary shenanigans for their own dock interop. Or maybe this is just the way dual barrel adapters+USB-PD devices work, since it can decide to sip power from one of two different electrical sources with different properties. In any case, this is a heads up for those of you who don't like the noise of the PSU when computer is off and have an XPS 15 (or maybe another similar Dell machine). Can't say this behavior will be the same across them, especially their newer, USB-C only XPS line.

Hello guys.

 

Is there anybody who installed Windows 10 on external SSD with this enclosure?

Because, i'm trying to install Win10 but it fails while booting with bsod: INACCESSIBLE_BOOT_DEVICE.

PS: SSD is installed in Mantiz Saturn Pro II MZ-03

Hello,

I've just received mine (from France). Easy to install on Windows, no need extra configuration.

Tested on an HP elitebook 840 G5 / HP Spectre Pro x360 G2 / Lenovo Yoga 730.

Maybe a little noisy but I don't have any point of comparison.

 

Does anyone have successfully tested a Wake On Lan? I Don't know if it's the new version of Windows 20H2 or the enclosure itself but I can't manage to do it.

It works with an HP USB-C Dock G4, so it's not a bios configuration.

@shufflepanda, it still MAY be a BIOS configuration (or maybe even BIOS parameters you can't access...). Dell, HP, Lenovo all do weird stuff with their own specific docks such as MAC pass-through or special TB3 security bypasses/behavioral changes. I would look for BIOS options to disable all Thunderbolt security (do so at your own risk of course). read those BIOS settings details thoroughly: on Dell machines, some Thunderbolt 3 configs (e.g. pre-boot modules) will only work with Fastboot NOT set to minimal.

I ordered one of these last week to use with my MBP 16". Overall, I'm happy with it, better than the Razer Core X eGPU. While I don't do any gaming on the MBP, I had to get an eGPU since the internal GPU in the MBP 16" will eat up 30W no matter what when connected to an external display, which leads to some very high temperatures and reduces the CPU performance.

However, the fan noise with the included PSU was annoying. It wasn't running at a high RPM but there was this persistent, buzzing noise. Almost sounded like coil whine. Not sure if that's normal, but I swapped out the PSU with a spare I had laying around and it is almost completely silent now, really can only hear it if I put my ear to the unit. Which is fantastic.

I used this PSU to replace the included one with: https://www.amazon.com/gp/product/B00918MEZG/

Not sure I'd recommend it though, it's a bit longer in length so it blocks the USB3 connectors on the board - you'll have to disconnect those. But otherwise the PSU fits fine. And yes, only 550W, but I'm using it with an 5500XT so it's more than enough.

So a bit of an update to keep this thread alive.

I've been having a torturous time with the noise produced by the FSP PSU just like @itsage originally reported, and then @littleNewton and some others expanded upon. Just contacted Mantiz support for a replacement PSU.

Unfortunately, it seems this didn't fully solve it for @littleNewton. I would happily consider modding this if I could use that 750W FSP PSU somewhere else where noise doesn't matter as much, but the cables are short and unusable in ATX. I'm also worried there is no clearly marked "CPU" power rail so I wonder if the third 6+2 pin cable could work. Even for a smaller build though, this PSU only has one MOLEX, one SATA power and one small connector (for a constant RPM fan or something else I believe, maybe RGB?). Not to mention an aftermarket PSU will have HUGE cables to organise inside the Mantiz... If anyone has any advice on what to use the FSP PSU for, I'm really considering a small form factor build for VR using those sw33t new Ryzens and the new GPUs coming/already out there. Perhaps with that I can also have my Oculus Quest 2 fully charging with Link cable, because it ain't charging so good on the Mantiz and I don't want to hook it to my FRAGILE 5290 2in1's USB ports.

On that note, any new developments on the USB power issues @arzen , @mac_editor ? I noticed nobody replied to @Mymantiz_John after he supplied some USB power meter tests. He does make a point that phones will charge lower than what is supplied (because you can only see the app with charge data with the phone, screen and CPU going, all sipping power...), but at the same time 7.5W should be providing a little more juice than that to iPhones and other peripherals. Maybe it's a power negotiation thing? Once again, what I can say is that my Quest 2 discharges relatively slower when I'm using it with Link, and I could go about 6h before it drains from full, which is about double it's standalone battery.

@tiago_borba, if you check my post history you can see the mods I did to my Saturn. It made it significantly more quiet.

TLDR; I used the Seasonic PX850 and a Noctua fan and dropped something like 10 dBA at the box and my desk. And it has a more pleasant sound. I run my Red Devil in Quiet mode as well.

Honestly, regarding the USB stuff, I’m disappointed but I almost never use the ports so it’s a non-issue for me. 

Edit: I attached a couple photos I took of the finalized build.

Dear all: 

We are collecting all information , feedback and users review everywhere and observe our outgoing quality every day. 

We found there’s very limited few cases claiming the PSU Fan noises. We had been awarded of this issue closely. So we started to research the root cause. 

1. First, all the PSU ( claimed Fan noise ) is still under the specification & standard.

900D60A0 B695 4AEF 9882 8F424AD3D39F

 2. BUT! We also detected the noise which came from the PSU started belonged to 800~1K Hz which is quite annoying for human been.

Solution/ Action:

we had changed and prepared the PSU with New fan ( make sure the noise is not in that annoying range 800~1K Hz ) , we can start to delivery NEW PSU to you if you do have this problem and we will also recall your PSU by providing return label. 

Send your request to [email protected] and once the swap stock is ready, we’ll reach you .

I received noise-related comments on eGPU.io forum on November 6, 2020.

I have known for a long time that the noise problem of Saturn Pro has always existed. The following is my advice to Mantiz technicians on September 23, 2020. In the conversation, I suggested that they replace the internal fan and listen to the changes in the noise.

Unfortunately, it seems that they did not do this. And their personnel have been insisting that their power supply is OK. However, as a consumer, I just want to say that what I care about is the experience, not some unknown international standards.

More than 40 days have passed. Until today, Mantiz has not actively contacted me. When I took the initiative to contact them, John of Mantiz finally admitted their problem, and then gave me a bit of science about human tolerance for noise.

By the way, I sent them the fan I removed before and lent them to study. Afterwards, Mantiz kept silent about the results of my fan research. Then today John told me under repeated questioning that they had dismantled the fan to pieces without my permission. I don't want to disassemble and replace the fan anymore, and the previous fan was cut out and cannot be easily installed back. So I asked John to pay me the market price of a Noctua fan, and the matter was over.

I appreciate John's manner of doing things, but I am dissatisfied with his results. Mantiz chose the wrong PSU customization plan.

@littlenewton, I understand the frustration as a consumer. I got two Mantiz Saturn Pro, one was a media sample (very early build) and another bought through US Amazon. I checked both units for the PSU fan. They are identical. I was only able to observe for the low pitch whirling noise after seeing reports in the forum. That fan was from the early production.

I've worked in support roles and Mantiz is more proactive than many manufacturers. In the eGPU space, they're second to none. We all would prefer a flawless product so that we don't need support. Unfortunately it's rarely the case with any products nowadays.
