New RTX 5070 in G5 5000

Just wondering if anyone thinks if it will be possible to get a 5070 inside a G5 5000 desktop. It has the exact same form factor as my current 3070 but has a 30 watt increase in power. I have the 500w psu does anyone know if it could handle that increase? Obviously I don't think anyone would be able to know for sure until March but theoretically? I have 10700f CPU, stock SSD, and 64gb ram. I would happily back down to 32 if needed. Thanks in advance!
