Hello, I want to to know if is possible replace  the default power supply to one of 650 W in order to use  the Radeon RX Vega 64 without freezes?

I won't suggest to do so. Because it will violate the warranty. and a new PSU is not certified by Intel Thunderbolt process nor the Power delivery test.

It will void your warrenty but the risk is low.  Regardless of it being certified, the PSU's used aren't doing anything special.

Just get some SFX Psu it's the best chance you will have of it fitting inside the chassis properly, I think all of these boxes are using SFX PSU's basically.

The PSU has no baring on power delivery beyond it's having the capacity to support it + the card that you have installed.  It's firmware controlled

1. While Peak current reach high, but at the same moment, 3.3 and 5V are zero or small, in this unbalance situation happened, it will cause the PSU set into protection mode and system will be freeze. 

2. Power Delivery: On/OFF must be pass for 1000 times & provide a stable enough by 3.3/5V/12V to the mainboard. A high power Walt PSU doesn't equal to the stable volt provider.

But if the PSU is gold, platinum or titanium 80+ certified it is supposed to provide stable voltage to the mainboard.

Gold/Titanium doesn't mean the flat current supply( Mainly the Power supply efficiency) . and also unable to avoid the crazy unbalance situation.

I don't understand what you mean by unbalance situation.

Could you please take a look at this thread?

This just vendor don't want you to change power supply, even change for most efficient and flattest  current one, this still no guarantee for you.

If you want to change, just change for asking no questions, you always get nothing from vendor, unless you get it from vendor.

That's the point.

Talk about over complicating something that is relatively low risk. It's not as if he's gonna ram 100000 volts through the board using some home-brew psu.

IRC Mantiz use the same board as Sonnet.  I've personally tried the 350w version of my sonnet with several PSU's (I was also considering flashing with Mantiz' firmware at some point to see what would happen :p)

Did you ever upgrade your power supply?

He is talking about cross load.  PSUs, especially inexpensive ones based on older designs, can really struggle to put out 98% of its power on the 12V rail without failing like we need with eGPUs.  There are also other issues.  You can't necessarily throw a higher wattage power supply at the problem and have success though if you wanted to try, I'd suggest the Corsair SF450, good unit.

It's an interesting topic.
