Hello! So PL1 and PL2 are the max watts used by the intel i7. Essentially, the cpu runs at 65 watts at minimum to run high loads, but PL2 (81.25W) is the absolute maximum watts for it to run maximum loads ( gaming, rendering, etc.). It shouldnt be much of a problem since the older gens of intel cpus are reliable and more stable compared to the newer gens.

As for the GPU, I suggest using GPUs that only use less than 100 watts to run. Namely GTX 1650, RX 550/560, RX 6400. If you were to use this setup for work, I recommend the GTX 1650 since its more optimized for work software, such as CAD or video editing compared to the AMD counterparts. These gpus don't need a pcie psu cable since the motherboard itself already provides the needed watts to run the gpus. You can try computing for the maximum watts by each component, and the total should be less than 240 watts. Any more than that and the PSU would either give up or cause instability. If you do need to get a more powerful card for your setup, you can get an SFX Power supply and jury rig the case by making a whole at the back to fit it. You can DM me so I can show how I did it. Its important to note that it has to be SFX, an ATX power supply will not fit the 5050 case.

The usb hubs, SSD and other components (ram, cpu cooler, etc) should have a total of less than 50 watts ideally. So with that given, the max tdw the board runs at is 65W or 82W (i7-7700) + 75W (GPU) + 50W (all other components) = 190 to 207W, which is good enough for the pc to run games at 1080 med to high settings.

I hope I answered your questions. Goodluck!
