I have put my specs into pc part picker (every single part) and it says that the estimated wattage is 433watts. My PSU is a 500w from an old pc, and I wondered if this would be too underpowered, and if I need some sort of buffer between peak power draw and the wattage my PSU is supplying. Thanks
Is my PSU underpowered/not for my pc

If it's a generic 500w from an old machine, I doubt it would hit 500w anyway and probably nearer 400w , so I wouldn't use it.
Your PSU is the heart of your pc, never cheap out on it.
Plenty of good quality 600w around at decent prices.

Agree with Brizzles here, that's cutting it very fine indeed. I wouldn't use it.

Post a picture of the PSU label and let us have a look

The part where you say "a 500w psu from a old pc" does not fill me with confidence. What make and model is the psu? Just how old is it? Without the make and model nobody can help you. If it's a cheap and nasty generic psu it will be lucky to deliver half of it's supposed 500w on the 12v rail where it's needed as they tend to have around half of their output on the minor rails.
Another thing is what exactly are you going to power? Again nobody can recommend a suitable psu without knowing what componeents it is going to power.

In theory: no, assuming the PC draws power from the same rails. That's important with old PSUs (like I assume you're using here) because they tend to have only 80% or less available on the +12v rail which modern PCs mostly use.
In reality: I would advise that you do not, due to the demand on the PSU itself (which results in more heat and noise) and that if you have any power spikes from the GPU, it might keep tripping and shut down, or invisibly go out of spec.
Or go bang, taking out other components
Whilst there is: you would be better putting the money you'd have to spend on the kit to do it in to a new PSU; especially when you would have to go to quite a bit of expense to verify the result via calibration.
