Hello, so i am using Ryzen 5700G with Jupiter X300, and it comes with the 19v 4.74a adapter, which is 90w. As i set the BIOS to 65w, sometimes the adapter can't handle the 5700G during gaming or heavy task as EDC will surge and causing the black screen ( and had to hard reset ) So i have been thinking a lot of ways how to stabilize my 5700G in the X300.

-What i have done so far are: set BIOS to 45W -> seems to be the most stable so far and does not spike the EDC so much.
-Sometimes meddle with PPT via Ryzen Master ( but it's unstable and random black screen happens )
-Undervolting the Cores clock speed manually via Ryzen Master ( no Curve ) -> which is ok, but i lose some core power.
-Turning off SMT

Lastly, i've think of another way on how can i use 65W without crashing the system. then i figure if it is fine to change adapter to 19V 6.32A ( 120w ) just like the Deskmini X300 version adapter, I've found a couple of aftermarket 120w Asus adapter.. would it be advisable to switch the adapter to 120W for the Jupiter? Thank you in advance

Switching to a 120W adaptor should be fine; the pc will only draw what power it needs, the PSU isn't pushing power in.
I have seen people using up to 180W Asus PSUs on Deskmini X300s to support higher performance with no problems.

I've got a 12V 400W brick for my deskmini A300. Anything from 12V to 19V will work on it (though officially only 19V). I don't see why the Jupiter would be any different.

Actually, i got a follow up question for you:

What's the CPU you use in your A300?
And at what Watt settings you use? 65W? 45W?
And by using a 400W adapter, does it stabilize the VRM by significant to the point you will not get any black screen during heavy gaming?

Currently have a 2400G running at stock so 65W. Ram runs at 3200 all day long. Gaming is with a dGPU so not sure how useful that would be.

The power brick.


The system.

Nice setup, right now, the highest ones i can find in the market is 19v 13.15a adapter which is 250w

I hope the 250w will be enough to supply the VRM under heavy load of the 5700G ( read around that the whole system consumption under a full load is around 200W for the 5700G ) including RAMS, SSDs etc

There's the Dellianware 330W bricks. I've got two (don't ask why). They're 19.5V.

Why?

I've run my DeskMini X300 from 120W/200W 19V adapters, 330W/400W 12V adapters.
5600G, 2x8GB DDR4 @ 4000MT/s -- with the 12V supplies I also had an eGPU.

Because my old laptop had 4930MX and a 980M both overclocked with custom cooling. Then I thought the A300 only worked with 19V bricks so my plan was to use one of these and a splitter to power an eGPU. In the end I want with an internal dGPU.
