Hello, I've recently picked up a Clevo P775TM1 (Metabox P775TM-G) for a decent price, however it has a critical issue I'm struggling to fix which the seller had not mentioned. The specs from my specific rebrand are as follows:
Model: Metabox Prime-X P775TM-G
Display: 17.3" FHD 1920 x 1080p WVA Matte 144Hz LED
Graphics: NVIDIA GeForce RTX 2080 8GB GDDR6 VRAM with G-Sync
Processor: Intel Core i7-9700K Octa Core (12M Cache, up to 4.90 GHz)
Memory: 32GB DDR4 2666MHZ (2 x 16GB)
Hard Drive: 1 x Samsung 970 EVO Plus 500GB PCle M.2, 1x Samsung 970 EVO Plus 1TB PCle M.2 (1.5TB total)
Wireless: Intel 9260 AC Dual Band WIFI/BT (up to 1.73 Gbps)
Whenever I open a game (e.g. basic Minecraft), the laptop has a tendency to completely shut off as if power to it is cut. I have taken it apart and cleaned all the dust out, and repasted both CPU and GPU. Monitoring temperatures during the shut off with HWInfo I can rule out overheating from being the culprit as CPU is around 70C and GPU around 60C when this occurs, with the laptop hotspots not even being warm to the touch. I've also attempted to run multiple stress tests on it, including Furmark and OCCT. Both chips reached extreme temperatures during the tests and throttled however I did not experience a shut off in either tests, only once upon launching Furmark (I have launched it numerous times). The OCCT Power test reported the CPU not exceeding 100W during the test while the GPU pulled a maximum of 150W (these will be important for later).
Interestingly, when running completely on battery I could not replicate this issue whatsoever no matter what I did, and removing the battery itself before plugging in the adapter and testing it again still caused it to shut down under the same conditions so I assume it can't be the battery. In the rare case where it does not immediately shut off under those circumstances, I could instead hear a high pitched electrical noise coming from either the PSU or from within the laptop itself (or both, could be coil whine?) I am using the original 330W brick, and I've also tried a completely new 330W brick which was provided with the laptop but the issue still persists across both bricks.
Most of the time this issue occurs when I switch into full screen mode, it immediately shuts off with no warning as if there's a power surge. Recklessly opening up background apps while tabbed out of a game can also lead to the same result. I noticed that turning on G-sync, or limitting the FPS in general decreases the chance of the issue occuring and I can play the game mostly fine, however by doing some of the things listed above I can still intentionally induce a sudden shut down. It's important to note that while doing basic tasks like browsing or watching YouTube this issue does not occur. I am planning to use this laptop for instensive graphical applications so I can't settle for that. Both Windows 11 and Windows 10 had the same result so it's not OS related.
Given these specific circumstances, my current suspicion is that the 330W power brick may not be providing enough power and when the laptop exceeds this 330W limit it shuts off, just like a regular PC would with an underpowered PSU. I have not tried running both chargers at once as I do not have a Y splitter for the two 330W adapters and it is quite expensive.
Would my suspicion be correct? Should I purchase a Y splitter (or even the 780W adapter) and try running it off both 330W PSUs? Does this laptop model require 330W+ with fully loaded CPU and GPU, how much power do these machines generally pull? The reason I am a bit sceptical is because this laptop actually shipped from Metabox with only a single 330W brick, so I assumed that's how it was intended to be used. Could this instead be a poor bios configuration, even if I reset everything to default? Would there be any other ways I could test this theory to see if it's correct before I purchase anything else for it? Could this be a much bigger hardware issue than a PSU?
I have seen so many accomplishments with Clevo machines here that are way beyond me, just thought maybe with such a knowledgeable community I would be able to find some assistance since it might be a simple fix.
Thanks for everyone's time
