How many W do i need to never upgrade again?

[Viesulis]

Im looking an 850w unit but ive seen people say that wasnt enough to keep their 7900XTX stable, do i need a 1000W for that? Current GPU is 6800XT but im using an underpowered psu for it.

What CPU is it paired with? Does the PC have 20 HDDs or just 1 little SSD?

What is your current PSU? if it were actually underpowered for the machine, you'd be experiencing sudden shutdowns. If your machine isn't doing this you probably shouldn't upgrade the PSU.

FSP 550 Silver, runs games fine but if i boot up furmark it crashes, and it ran fine on my mates 650W gold.

For now 3600, probably upgrading to 5700X3D soon. 2 HHD's 1, PCIE SSD, 1 SATA SSD

with 5700x3D you're probably fine with a high quality 850W PSU for XTX

"it crashes" or "it instantly shuts off"... I assume you meant the latter, but if it is the former I'd suspect a software issue.

Well, look you could go out and get a 1500W PSU to guarantee that in every case you'll never need to upgrade again... but that isn't sensiable. Given the kind of hardware you are buying, you won't need more than a 850W to get by for the lifetime of a PSU (a good 650 or 750 would run your current machine imo).

The pc instantly turns off, probably tripping over current, i guess thats why they call furmark a power virus. In even very demanding games theres no issues.

If GPU mining becomes viable again, and you decide to do it, you'll just want the highest wattage PSU you can find, and shove as many graphics cards in as possible. That would probably require one of the few 2000W PSUs out there.

If you want a more realistic answer, that would depend on what you're likely to upgrade to. If you're on a mainstream platform and with a single GPU, and use ambient cooling, a good 850W has always been enough, and is still plenty. The important part though is "good". If you can't afford a high end 850W PSU, you don't need it, and you should instead focus on getting a good PSU, instead of an unnecessarily high wattage PSU.

Ive been using crappy power supplies for a decade, think its time to buy something proper. Im thinking Deepcool PD850M, has decent reviews and isnt too expensive.

Tier List for PSUs, CTRL+F search function works wonders here

PSU's degrade with time, there is no psu that I would run "forever". After 10 years or so, I tend to swap them out.

 

*edit* The degredation depends on many things such as temp and how close to the line you push it...

Note that a 2000 watt power supply requires a 20 amp circuit on 120v electric systems (North America and Japan). Intermittent loads can burst up to 1850 watts, but code says a continuous load should only be 1500 watts (80% of a circuit's rating).

No worries im in Europe, so i could pull 3000W if such a psu existed

redo your title, as the quesion is nonsensical and has no foundation to ever be answered.

 

You need an 850w PSU for the 7900XTX.  Probably a 1000w if you're upgrading to a 9xxxXTX later?  Who can know.

Being in Europe, could you afford 3000w usage prices?

The title is rhetorical. And no i cant, but the thought is nice.

I went for 1500, go big or go home

 

But I use it, for a PC with a single graphics card 1000 could be overkill. Unless you go for a joke card like the 4090 and an overclocked CPU.

I kinda based my choice on what PSU does a 4090 call for lol
