extra power supply with gaming laptop ?

[alias9969]

Hello,
I have a gaming laptop with an external 330w power supply, and inboard rtx 3080Ti, many fans and heating issues...
I think i m a little bit short in power supply.
I would like to know if adding an axtra power supply using usb C power delivery sockets will improve my laptop performances and/or improve heating issues?
It is equiped with female usb C PD and thunderbolt 4 sockets.

no. if the laptop comes with that power supply, adding more could damage it. It is clearly designed to work with what it comes with.

ok,
Adding all the components power consumption make the power supply a little bite weak at peak.
A usb power adaptor has different levels of charging (boost, check...)
I thought it could not harm the computer even thought it is certainly only charging the battery so it won t have any effect on computer performances.

what make/model laptop is it?

I don't think its wise to use additional power items that didn't come with laptop to power it.
You could break it and that isn't a result I assume you want.

Indeed i would prefer it to run fine...
Gaming range are not eco friendly and for PC (gaming or heavy configuration) they need special external power supply. These does not exists for laptops.

2 ram
360Hz 1ms screen

I made an addition of all i could think about (fans, motherboard, screen, speakers, keyboard, mouse, ..) and it seams to be weak at peak consumption.

But now i guess that the USB C PD is only charging the battery and does not really help.
I use it as a desktop...
