Just make sure it's running two separate power connectors and your golden. (GPU)

Ye, which is just silly on a 7900xt. Back in the day a R9 295x2 used just 2 connectors. 500w no issues.

I so want one of these 7900XTX.

If it gives you comfort i use a 650W psu with a 5800x3d and 7900xt. Runs fine, although it is a good quality PSU (which is more important than the wattage rating) and i did a fair bit of research beforehand to be sure.
I definitely wouldn’t push my system any further up the foodchain without upgrading my power supply but it’s fine and im sure yours will be too.

I've ordered the xfx flavoured one but it does seem to need a lot of power. I think I have a 750 watt psu but not certain. I think I'm going to need to upgrade this too. Was looking at a corsair 850 watt jobby but I'll see how this behaves first.
I have had poor experiences with xfx previously but this was years ago with an AMD 5950 gpu iirc. From. What I've read, they seem better these days.

Budget depending I would say upgrading from 750 to 850 might just give you the same problem in a few years so it depends on how frequently you want to be upgrading / finding yourself needing to upgrade.
I'm on 750 atm, likely to go to 1000 with my next upgrade.
You may have to undervolt it a bit as mine can pull 450 watts. You won’t loose much performance by undervolting and in some circumstances it will improve.

You can try it at -10 Power Limit too if you have issues, would buy you some time.
My last 2 cards have been XFX black edition cards 6800xt and my current 7900xtx. For me it's now my go to brand for AMD cards. Great build quality and one of top coolers you can get.
I've had my 7900xtx nearly 2 years now and it's been my best card yet.

The pc would not boot with only 2 gpu power plugs connected, so I have ordered a new PSU. No plans to update again for many years and got a good price on a Corsair 850w modular unit.

I use an RM850x and it's powered everything I've thrown at it fine inc a high-wattage Intel/4090 oc combo
(and current 7800X3D/7900XTX ofc)

This new PSU etc will give me a good excuse to clean out years of crud from the PC. Living right next to a main road where there were loads of buses and lorries etc for years has caused a bit of a build up. There was some nasty stuff I pulled out if my top fan the other day.
My cat loves sitting in front of the PC when it’s on. So I know what you mean.

Well, this is very nice indeed. I big upgrade for FPS and much quieter too. Loving it so far.
I just have to tidy the leads up a bit and it will be fully sorted.

It's just a little annoying/depressing seeing everyone have such good experiences when I (once again?) got a turkey of a card 
Consider me jealous.

Sapphire 7900XT Pulse.
I hear good things about the Nitro+ line but I'm guessing Pulse is their cheapo line. It doesn't "feel" quality, like something could snap at any minute (from memory it's been a while since I've actually handled it).
If I lower the voltage it's unstable, if I increase the max clocks it's unstable, if I leave it stock it runs hot.
It has 2 HDMI ports but they don't both work at the same time, so that feels pointless.
When I got it the memory wouldn't clock down at idle, so it ran warm at idle and it prevented the fan from entering zero-rpm mode. I believe this is now fixed with updated rivers (unless it's been re-broken again) but first impressions matter and that wasn't ideal.
