I bought MV and the PSU is not working.

I cannot find my order number and customer service are not willing to help.

Any solution?

Where did you buy it from? When did you buy it?

If you are sure it's the PSU that's faulty, just buy a replacement PSU and swap it in, it's not hard.

Replacement PSU should be SFX, and minimum 500W. I personally replaced mine with an enermax SFX 650w.

Just be sure it's the PSU.

Get in touch with the online dealer or provide some exchanges such as emails etc.

to test psu, just short the power on signal with a jumper or paper clip then turn it on. Best is if you have a multimeter to measure the rails, but just put your ear to the psu to hear if the fan is running etc.

That's great news... and also bad news. I was hoping it would be the PSU because it's easily replaceable. If it's the motherboard or daughter board, and Mantiz doesn't reply you it'll be tough.

I sent a support request email about a month ago to them and they still have not gotten back to me. You can also try to remove the daughter board and see if it spins up - may I know what exactly are the symptoms? Have you tried the following:

  1. Another TB3 cable
  2. A different computer
  3. Another GPU

The Mantiz Venus behaviour is such that it will not power up unless it detects a proper TB3 connection. I strongly suggest you try a different cable or different computer. Or test your current computer and TB3 cable with another TB3 device. Remove all USB peripherals and SATA drive connected to the Mantiz Venus.

EDIT: ATX 24 pinout for your reference to test with voltmeter.

@joe_fabio it looks like you have the same issue i had with my Mantiz, the quality of their board is not that good, it used to be working awesome and then after a year it started to randomly shutdown after 15 minutes of use, then it a couple of months later total shutdown, i contacted support and they asked me to ship it to them, which i did and they validated the logic board and said that it was working perfect, but i asked them to ship another logic board just in case and the agreed, however the new board worked for 2 months and the same behavior started to happen, i tried different PSU, TB3 cables (active/passive), power cables, different computers and no luck, i tried to contact Mantiz support but they just plain ignored me and won't answer twitter or here, i think they gave up. So at the end, I said fu.. it and bought a Razer Core X and it has been amazing (I miss the ability to connect usb devices and have a internal drive inside the Mantiz, but it was my only option)

Don’t they use the same logic board as Sonnet BB?
I have yet to have any issues with either of mine.
I almost never shut down, so one of them is running at any given time (which one depends on which OS I am in).

Both of mine are permanently connected, do you guys do a lot of hot plugging?
