For anyone viewing this, Dell support already reached out (superb service) and confirmed a peak draw of 65w is within spec for the model and CPU combination.  Seems Dell didn't only get the TGP correct for the GPU (maximum spec by NVidia) but also managed to allow the CPU the correct and maximum TDP.  Dell have done a cracking job with the G15 5515!
Hi All, I've got a G15 5515 with a Ryzen 7 5800H and when running a Cinebench multi core test the CPU power peaks at 65w (measured on HWInfo). It settles down at 45w after a while but peaking at 65w seems a bit high. Is this regular behaviour or a BIOS bug? Thanks all!
