I saw this review...but I don't even consider the possibility of the gpu being limited to 55W when in full load simultaneously with the CPU. It's certainly a bug to be fixed with an update. His at least has a sustained power of 85W with the i9 in multicore full load. Impossible for dell to have done all this internal update to get these results. I have a Precision 7540 and I get 75W sustained on the CPU (i7-9750H) and 60W on the GPU (T2000) running Prime95 and Furmark simultaneously.

It's not a matter of squeezing the most out of the hardware, looking for every point in benchmarks, but the performance of your 7770 in both CPU and GPU is below acceptable. If this is the standard the new 7770 represents a downgrade in cooling capacity compared to the 7740/7750/7760. On the CBR23 the score, sustained power and temperatures are horrible. A performance level close to that achieved by the GT77 was never expected, but an acceptable performance for this precision would be able to maintain the 85W of the PL1 without thermal throttling reaching 17500-18000 on the CBR23. On Time Spy its CPU score is super low, at the level of an average i7-11800H. The 3080Ti is also low, with a maximum TGP of 150W its score should be ~12000. My guess is your unit has a problem with either misapplying thermal paste or poor contact heatsink... Otherwise, why a high-end i9 HX + high end dGPU if the system can't extract minimally decent performance for the hardware?

I contacted support and they don't know if it's a lock done on purpose by Dell, if it's a problem or something else. They simply claim that Dell cannot guarantee the performance of third-party products. Luckily I have a P2723QE monitor with USB-C Hub with 90W Power Delivery. I'm on a business trip and as soon as I get back to the office I'm going to test it on a fully Dell system. At most I have faulty Tunderbolt ports and I will get a 7670 in return... Thank you very much for your attention Aaron44126!

Hey guys, I bought a 100W USB-C GaN charger with the intention of using it in my Precision 7540 when I'm out of the office, obviously for lighter tasks...I've tried everything and I can't charge the laptop through the Thunderbolt ports. Windows informs that the system is not being charged and in another message it informs that a charger of at least 90W is necessary for this to work. Well, I've already tested this GaN on two Inspirons and it worked perfectly delivering all the machines' performance. Are the Precision 7540's Thunderbolt ports limited for charging via third-party chargers? I have a problem? I often use both USB-C ports with flash drives, external hard drives, smartphones, etc... Sorry for my english, it's not my native language.
