![]() I don't have triple AAA games installed so for now cannot test it with something like Cyberpunk 2077. 35W for GPU and 20W for CPU seems to work with the barrel adapter without discharging. 700mV and 1465 MHz on the RTX 3050, so more or less base frequencies. UPDATE: I tested another undervolt that worked at least for now. I don't know if this affected the result but I used before AATU on the Ryzen 5800HS to limit the TDP to 20W and the Temp Limit to 69C, so the fans didn't go crazy loud.īTW, I'm using the Baseus USB-C 100W GaN II Charger with only 1 USB Type-C port and the original cable. But for now, I can be satisfied that the experiment worked. With this, it's been several hours of testing and maybe I got lucky and when I unplug and plug it back in it will go haywire, who knows lol. In fact, I was playing for 1 hour constantly monitoring for charging and discharging in BatteryBar and there was none, battery level stayed exactly the same and 0.0W on HWiNFO. My big surprise was, that with these tweaks done, I could play this game with the NVIDIA RTX while using the USB-C charger with barrel adapter and no damage to the battery! Among the few games I have on my laptop, MMOs like FFXIV at 2K pushed the GPU load to almost 100%, consuming almost 30W in my case (+200 MHz OC memory clock). In my particular case, it was 631mV, with a frequency of 1237 MHz.įor many it may seem stupid to lose hundreds of MHz on an already underpowered graphics card, but that doesn't matter to me, as I had achieved my goal. Knowing that, I discovered a "sweet spot" for my RTX 3050 to consume as little as possible and offer enough voltage so that the memory and core clock could be maintained. But that's because they've never tried modifying the MSI Afterburner defaults, of course. I kept getting more aggressive with the undervolt, continuing with 800mV, 750mV and up to 700mV which many consider the limit. First, I tried to undevolt at 850mV using MSI Afterburner, but at this voltage and frequency of 1950 MHz, the power consumption shot up to more than 50W and the barrel adapter with USB-C didn't work. So, I didn't want to give up and I wanted to get my dGPU working, in my case, an NVIDIA RTX 3050. And best of all, there was no more battery drain! If I limited it to 80% via the MyAsus app, it stayed there! 0.0W according to BatteryBar.īut I was limited to only using the integrated graphics, which in my case, having an ASUS Zephyrus G14 2021 with Ryzen 5800HS and NVIDIA RTX 3050, its iGPU is very underpowered. ![]() As soon as I tried the USB-C barrel adapter here, everything worked without disconnections. One of these was to keep the battery above 75% or close to 80%. But then, I remembered some advice given by other users. The cable was constantly plugging and unplugging, alternating between battery mode and plugged mode whenever I used the dedicated GPU. It arrived today and I was able to test it and unfortunately, I had the same problems as other users. Since direct links are considered spam, I searched on AliExpress for " 100W USB C Female to 6.0\3.7 mm male plug adapter ", the specific model is " 100WZJT-6037*", this is a 90 angled connector. ![]() To solve this, the first thing I decided to do was to buy a USB-C to barrel adapter. ![]() ![]() However, the results were the same, there is no usb-c passthrough and therefore, the battery wears out with continuous charge and discharge cycles. Like many on this reddit, I too thought of using a USB-C charger as it is a much smaller and lighter alternative to the barrel charger. ![]()
