    ~175W of power roughly means your 220W PSU should run/charge at the same time.

    Assuming you tried the 220W based on the output?

    Power adapters should be pretty simple to get a decent one as they're all made in the same places with the same parts but, it's not the case.

    I'm not sure you even need the 330W based on the HWINFO though you could run into insufficient power potentially if the driver allows more power to the RTX down the road or there's a BIOS change that allow higher CPU combined to breach 220W overall.

    Actually it was not max performance of the VGU + GPU (CPU should use approx 90w, however benchmark was using mostly only GPU resorses), when power reach maximum (which could be provided by the adapter) - PSU switched off. And performance drop down due to fact that GPU and laptop start working form the battery resourse only.

    And I will try to explain why.

    I have removed covers on PSU. Please see self-explanatory photoes:

    so, I'm not a specialist, however it looks like chinese fake...

    It is not 330w PSU, however only 220w...

    At least during gaming and real sterss test my configuration shoud take approx at least 90w+150w=240w ... however PSU give only 220w...
    I commence suppose something strange, once I was trying to use my previous original PSU with power 230w and get better performance.

    So... what do you thing about it? Any comments will be appriciated.

    Well, it's a power issue like I've been saying due to the symptoms you were describing.

    220W repackaged as 330W though is fraud. I'm thinking the 180W PSU I bought might have a similar issue but, I already pestered them into a refund through Amazon warranty. Took a couple of weeks of badgering them about the power issue but finally got the refund.

    As to next steps is finding a reputable dealer for a 330W PSU. The one I'm using that came is labeled Chicony and it's rock solid but expensive compared to the knockoff's by $30-$40 more.

    Playing around with power supplies though and taking bits and pieces to make something work not as designed has given me insight to these pesky little bricks and how they interact with our laptops.

    I'm sure you could go with a HP / Dell / OEM adapter as long as the tip is the right size. One thing I noticed looking up the P/N on the photo is it's producing barrel tips and square tips.

    Thanks for sharring your thoughts.
    I think to buy this one from Germany (hope this one is original)

    https://www.ipc-computer.eu/notebook-spareparts/adaptere/adapter-adp-330ab-d-1

    as you can see - end of the plug coming in laptop is "black" (same as on my previous), since it is "yellow" on fake which I'm bouht from e-bay. I have seen (cheep with "yellow"), "original" with "black" are slightly expencive.

    Color of the tip is an indicator sometimes. When I was doing the USB-PD swap for a brick both cables I chose looked the same but, one didn't perform well and the USB-C side had to be flipped to trigger proper current. The second cable worked in either orientation just fine. Getting beyond the 60W performance though doesn't work due to the 100W PD specification and won't negotiate down properly to give at least 100W when the system tries to draw 119W.

    Bricks can be rated higher and perform downwards to the max draw of 120W though. When it comes to powering a $1000+ piece of equipment though being cheap sometimes isn't the best idea especially with power. ram/drives/wifi/etc though isn't as big of a deal and easier to diagnose which part isn't working up to spec.

    Reviews though can clue you in on whether something works as designed if you find it listed on Amazon or the like. I've had maybe 1 or 2 experiences on ebay where something didn't worked as claimed and it was a hassle to deal with replacing the products by needing to source a different seller and wait on it to be delivered. Going with a seller specializing in laptop parts and accessories should yield a better result though for getting the most out of your new RTX.
