Any chance your issue is the same as Extremely weird dGPU power behaviour on 140W chargers (moved)? Seems like a lot of 140W USB-PD chargers and Framework 16 laptops don’t negotiate power in a friendly way, Baseus chargers being the exception.
i contributed to the Github Issue, as i wrote about “jumpy” GPU Performance since the Introduction of the 3.05 Bios

It looks like it could be related, at least with what I’m seeing regarding the symptoms.
Edit: Upon further reading it looks like it could actually be the same issue. I think the presumption was that with a higher wattage charger the battery draw and power fluctuations would be non-existent.

It literally is the same negotiation issue. The baseus works wonders, but the UGREEN Nexode 160W and the Delta 240W show the same symptoms.
Unstable dGPU power, a lot of stuttering.

I have recently filed a git issue that seems to be similar to what you described (and plus some more). I did some testing and if you and others see similar results to mine it would point to PD being wonky rather than GPU problems.
Yes, the problem is probably the USB PD negotiation. The thing is, you need the dGPU to be installed and under stress to replicate the issue, because the CPU power delivery is flawless. The problem only appears on the dGPU in combination with some >=140W power supplies.
It’s like the laptop has a hard time allocating the PSU power to the dGPU… Weird.

not necessarily, there might be a case where A) CPU doesn’t pull more then 60w so it can get all the power from the battery meaning the power negotiation/plan is simplified and only factors in the powerplan set systemwide. The GPU can easily draw more than the battery max output and needs to know what is the connected charger wattage. B) i forgot what case B was while writing case A :-p

Just receive mine, I get what you guys are talking about…the gpu power consumption is truly in a roller coaster way…gaming on performance mode is a disaster with tones of stuck. I feel like the tdp is jumping between 120 to 145 while the battery is charged a little and discharged a little. (Mine laptop pull ~5w out of battery on 145w tdp)
Hope they could fix it soon.
Just saw a CES announcement for a multi-port USB-C charging brick that supports 500W total, with 1 port supporting 240W.

The brick is too big, I think many people need a 240w brick in a compact size.
It’s named Desktop Charger 500W. It’s not meant to be a travel charger.
And it’s also among the first 240W PD capable chargers. They may get a bit smaller over time. Though there will be hard limits on size, until we have better tech than the new gallium nitride chips. Unless you’re ok with your charger roasting itself and having a short life.

Is SlimQ’s 500W one any smaller? It doesn’t look like it to me, but I don’t see measurements for the Ugreen one.
The slimq 500W isn’t a PD240 charger. It looks like it’s one of their universal jack chargers for gaming laptops, with the 2 usb c ports doing only 100W
It also looks much bigger, just from the scale of those usb c ports

This looks like a desktop computer’s PSU
With problems of dgpu stuttering with 240W psu. Has anyone discovered what volts the 240W psu supplies the laptop with? I would have thought that the most stable option would be the laptop to ask the psu to sit at 48v. And then the laptop can just draw anything from 0 Amps up to 5 Amps when it sees fit. If it keeps asking the psu for different volts, that could be difficult to manage the power stability.

@knipp30 was joking. That is a desktop psu

Hello framework community
I have recently picked up a 240 watt USB-C PD 3.1 charger from Mouser Electronics made by delta the ADP-240KB BA. I tested my Framework 16 + GPU with an endurance stress test to verify that the battery drain under heavy load issue was solved with higher available power; it managed to charge during the 3D Mark endurance stress test that would drain it otherwise.
If anyone is interested the brick is larger with an integrated USB-C cable so not ideal but seems to be good quality, Delta is a well known manufacturer.

Check the dGPU power draw stability. Can it pull 90-100w sustained during gaming/benchmark? My experience tells me that with Helldivers 2, Age of Empires IV and 3DMark the power draw is very unstable when using the 240w charger on max performance.
The Framework 180W and the Baseus 140W works wonders. The UGREEN Nexode 160W and the Delta 240W do not.
