330W Dell adapter for GL702VSK with i7+1070 (where do I find the converter?!)

Hello,
After a bit of reading and a lot of stuttering/crashing on some of less efficient games and etc. I decided that my 230W power brick may not be sufficient for my ROG GL702VSK and I read about someone ( https://rog.asus.com/forum/showthre...er-charger-very-underpowered-and-the-solution) who did what I want to do.

Here's the problem;
Where the heck do I find a 7.4mm x 5.0mm to 6.0mm x 3.7mm converter?!

For now, I ordered the following:
1X DC 7.4 x 5.0 mm 7.4*0.6 female to 7.4*5.0 4.5*0.6 4.8*1.7mm 5.5*2.1/5.5x2.1mm male jack for HP DELL laptop power adapter plug ( https://www.aliexpress.com/item/4001093944364.html?spm=a2g0s.9042311.0.0.13ae4c4djH2k9V) [5.5x2.1]



1PCS 6.0*3.7 mm Male to 5.5*2.1 mm Female With Pin DC AC Power Adapter Plug Connector DC Jack Tip Notebook Laptop For Asus ( https://www.aliexpress.com/item/1005003167918821.html?spm=a2g0s.9042311.0.0.13ae4c4djH2k9V)

So basically going from Dell's 7.4mm x 5.0mm male -> {7.4mm x 5.0mm female [first plug] 5.5mm x 2.1mm male} -> {5.5mm x 2.1mm female [second plug] 6.0mm x 3.7mm male } -> to my ROG GL702VSK.

It "should" work but I am skeptical for the power rating for the 5.5mm x 2.1mm "interface" plug.

Do you guys have a better source to go from a AW/Dell brick to ROG GL702VS?

 

Undervolting GPU did the trick for the 230W power brick. I don't get it, why don't they just build a laptop that works out of the box instead of the user having to undervolt everything and put aftermarket parts on it.
