Title ^

Also imagine i get a 750W PSU, will it always continually draw all full 750W all the time or draw what it needs?

I would go with the higher wattage to give you more headroom. No they don't constantly run at full whack. Depending on the overall system you will probably be drawing under 400 watts but the extra headroom is useful so all the rails will have the right amount of voltage etc.
Should be fine, (if a decent brand/unit anyway)

(500w is pretty much fine for any single gpu setup, if you were going to SLI or xfire, then it would be viable to go for a 750w)
Google jonnyguru and do a lot of research into a good psu. A good psu you won't ever think about, a cheap rebadge will give you random issues. It's better to research a good brand as 500w rating isn't the same on every psu.

hm after researching them all and the one you recommended is one of the best will get that one the G2 cheers! My first gaming PC this
500W will do but just don't get a cheap generic one. Get a trusted brand, they are reliable, provide the power within the required ranges and last longer.

That is unless you are going to go Crossfire, and they only draw what they need.

Double check the figures over here: uk.pcpartpicker.com/
As stated, a quality 500w PSU is plenty.

Yeah but 99% of the time if you have problems with your graphics card or system crashing randomly the 1st thing people ask you is what PSU you have, you say 500w and people blame the weak link. With a psu it's better not to penny pinch, I've done it before in the past and it doesn't pay off, to put it bluntly there aren't many people out there that say I wish I hadn't bought that top spec PSU. I also buy WD Reds instead of the cheaper WD Greens.

In no way am I suggesting to penny pinch, not at all. You don't need to go over the top though with a PSU. Of course power efficiency and quality is important.
