I am on a budget for a build with a Vega 56(210W TDP) and an i7-4770(84W TDP). I was wondering what the wattage of my PSU should be. Also if someone could help me find a good budget PSU I would greatly appreciate it, I live in the UK.

Thanks for answering.

A high quality 650W will be plenty, even with future upgrades to the CPU. Here are a couple good ones.

These are in order of best to worst.

80+ Bronze:

In all honesty the bronze PSUs aren't worth it. Even the worst of the gold PSUs I listed is better than the bronze ones at the same price. The added money for the Focus GX is worth it if you ask me.
 
Solution
You do not need a 750W PSU for that GPU. Even a system with Vega 64, stock 9900k, & 360mm AIO won't need more than a 650W PSU. For almost any non HEDT or single GPU system you don't need anything more than 650W. Using a PSU calculator gives you a worst case power draw but at least says what you will need in a worst case instance.
 
Here is the 9900k calculation:

Then again the 750watt TXM is only a few pounds more so can't hurt.
Just looked at the pricing and the 750W TXM is 2 Quid cheaper than the 650W Seasonic Focus GX. It is the whole 6 one way, half dozen the other. Will it hurt to have a 750W, not at all especially when a high quality 750W is cheaper than the 650W. I was just making a response to Calvin and trying to show what requires more than a 650W. He actually like an 850W which would be a huge waste of money.
 
I get it, and yes 650watt would be fine, but maybe with that 750watt will the system be a bit more quiet since load will be less.

That 850watt linked is "renewed" as i see, so there it depends if you want to take the chance with something returned/refurbished. It seems to be gone btw. Although an 850wattTXM is even cheaper, but again refurbished and price is in dollars. Nevertheless not very expensive (a huge waste of money) as you mentioned.
