So I believe AMD lists the total board power of RX 7900 XTX at 355 watts. I picked up the Asrock Phantom Gaming version which has 3 8 pin connectors on it and my X670E ProArt has an additional 8 pin PCIe connector on it to provide additional power to the PCIe slots. So theoretically there's 600 watts of power being provided right there not including the 24 pin motherboard power connector that should provide the slot power as well. But HWMonitor is reporting that the max TBP is 607 W, is it even possible for an RX 7900 XTX to draw that much power?

I would say NO. HWmonitor is screwing up. Otherwise you would be putting out a fire.

I am not sure... but is 103c hotspot a normal thing?? do you have a reference card?

It's not a reference card and the thing is huge, first card I've ever had really test the limits of my case with it being 330mm. https://pg.asrock.com/Graphics-Card/AMD/Radeon RX 7900 XTX Phantom Gaming 24GB OC/index.asp

I have a 120 mm intake fan blowing directly on it because of it's size. I think the hotspot is fine, 110C is where you start to get concerned IIRC.

That's just the reference power number though correct? There's got to be a reason that they put 3 8 pin connectors on this card right?

Fine here is the asrock taichi 3 8pin, you're not going to do 600w on these things.

I have Red Devil 7900 XTX and Adrenalin is showing up to 431w power draw (with +15% power slider).
Might try and flash BIOS that gives even more power because my temps don't exceed 70c (gpu) / 90c (hotspot).
