How low can I go? (PSU question)

So my insomnia finally paid off, and while browsing for a 7900 GRE at 2am I saw a 7900 XT Nitro+ for 8 quid new on a big retailer site (so I don't feel too guilty, listing was removed a couple of hours later), bought it and its on its way to me now.
So assuming its not a brick (will video me opening it just in case it is.. lol), I was wondering if I will be able to use it on my Thermaltake 630w PSU with a 5800x if I enable its silent/low power bios until I can get something better sorted? I don't really want to order a PSU ahead of time in case I do receive said brick :D
 
Cheers, guys, I assume its safe to power it on and check its fine, and then order a better PSU, any recommendations for around 100?

And yeah 8 quid (10 euros), clearly a pricing error, or I'm going to get a brick, or as my mates recon, a keychain of the GPU :D Lets see!

Gets an 8 quid bargain, immediately buys a £100 PSU. Don't you love PCs? I think you should get a 5800X3D next, 'cos.. you know, bottlenecks ;) :D

OCUK have the RMx 750 at exactly £100, it is the old model, but that doesn't matter for your 7900 Nitro.

Seasonic's GX-850 is £20 more, but again that is the old model.

The SHIFT is Corsair's updated ATX 3.0/PCIE 5.0 PSU with a 16 pin for the newer nvidia cards, but it will only fit if your case supports the side-mounted cables.

My basket at OcUK:

Total: £443.92 (includes delivery: £0.00)​

Its not pretty but what you're looking for in a PSU is safe, reliable and high quality, that's what you get with SeaSonic.
750 Watts is plenty, i run an RX 7800 XT overclocked and a Ryzen 5800X on a 7 years old SeaSonic 650 Watt PSU

Cheers guys, my PC stays firmly under the table and receives regular kicks, so pretty is not high on my requirements list, have heard of Seasonic so will go with them. Now just waiting to see what actually arrives :D
 
Update: Apparently some computer error is causing trouble for the delivery company, my brick is out there alone in its box :(
 
Dammit no updates to shipping just says it's been delayed indefinitely. Starting to think they realised their mistake and put a recall on the delivery, back to looking at 7900 GREs, at least I won't need a new PSU!
 
I wouldn't be so sure about that. My pc with a 65w locked 12600 non K and a 7900GRE will easily pull over 500w if you let the 7900GRE have all the power it wants. I have mine undervolted now and it's brought the GPU only power draw down to 200w or less depending on the game. Thermaltake hasn't sold a 630w psu for years, the last one being the Smart series and that was a terrible psu so just how old is that psu of yours? Most were also only 588w on the 12v rail which would be uncomfortably close to max power draw. I think you should budget for a decent psu as well.

With the massive IT issues lately I wouldn't panic just yet.

Yup well determined, it's a Smart SE 630W.

That's a shame, I always rated Thermal Take, I guess they dropped off :( I do also have a 600ish watt Berlin model by them if that's better? (that's about 13 years old though)

Will take your advice and wait another month to do it all at once, my 1080 can take another month of abuse :D

Seems they cancelled the delivery but surprised they just erased it's existence. Why do I get the feeling that getting my money back is going to be a massive pita!

Can you not log in and look at your order history on the retailer website you bought it from ?
