I can't find any SFX PSU's that are palatium rated higher then 750w? Would a 3080 Ti be ok on my Corsair SF750?

RTX 3080 Ti on a Corsair SF750 SFX PSU?

Since its launch in 2015, the SFX-L form factor has garnered popular recognition and support among enthusiasts with its larger 120mm fan able to achieve better balance of power and quietness in small form factor PCs than what was possible with standard SFX. And as a leader in power supply...

I’m running a 3080 on a SF750.
Not sure that the psu could run a 3080ti (especially with a high end cpu).
The SF750 will let you draw more than 850 watts without shutting down but I don’t think that’s such a hot idea.
There are 850 watt SF PSUs around but I don’t know their efficiency rating.
Edit; gold rated

Thank you both
Yes it will be fine, im running a 3090 and a 12700k overclocked on a SF750 and it handles it like nothing. These psu's can handle quite abit without any issue.

Nice. The SF750 is a small beast of a psu.

I have a 11900k Great! Thanks for the info
It really is, i can't remember who did a test but it went all the way upto 850w without any issues, just works and the fan (although abit noisy) keeps it all in check.

Tomshardware. It's in their testing section in the review.
Ah yeah! I think maybe optimum tech or Gamers nexus on youtube did a video on it as well. I remember watching it before making my purchase.

I got mine on special for £100. Bargain. Been meaning to go ITX for ages. Will stick to ITX for the future too.
I really want to but judging by how much power these new gpu's are going to need, it's hard to stay in a small box for the foreseeable future especially if the cards get any thicker than 3 slots though i'm usually watercooling anyway.

I read somewhere that said the SF750 would only be good with a 3080 and any higher not be good? I did think it is a palatium PSU so it should run a 3090 at least without issue.

3090 might work on an SF 750 with its capacity of 850 watts but I wouldn't want to run that for a long time in an ITX build.
Depends entirely on the whole combination. Can get power hungry CPUs and power hungry 3090's / 3080Ti's that go well above FE at times when OC'd.
Been using a 3090FE with 9900k, with both OC'd and using a 750w SFX units for coming up to two years. 0 issues, even in most demanding games with RT cranked up etc so its drawing its max limit. As I say though, some SKU's can draw a lot more power.

I had to upgrade my old SFX 650W to the Silverstone SX1000.
The transient power spikes was causing the odd random restarts whilst gaming, and I already undervolted my 3080 FE.

Got mine for the same price.
Had to get a new PSU for the 3080 so figured i may as well get this incase i go ITX at some time.
Fantastic little PSU and was not expecting the braiding on the cables to be this good.
No personal experience of these high end GPUs, but I came in here to say that my worry wouldn't be the normal load but rather is be worried about the spikes.
I'm sure there's more than one way to measure this but Techpowerup's W1zzard has been putting that into all reviews for a while so it's always worth looking at the most recent GPU review there:
ASRock Radeon RX 6950 XT OC Formula Review
ASRock's Radeon RX 6950 XT OC Formula is one of the fastest RX 6950 XT custom designs we've reviewed, and its great cooler achieves excellent temperatures. The card also has a super-strong VRM with 21-phases, more than any other RX 6950 XT.
Some AIB models may be worse than others so that's another thing to beat in mind. Think it IgorsLab also measures spikes.
