I hopefully your pc building knowledge is better than your PSU knowledge! :p The efficiency rating doesn't mean you only get that percentage of the PSU's rated power output. It's actually how many watts are drawn from the wall socket compared to what is actually being supplied to your PC. A more efficient PSU will have a smaller delta between wattage drawn from the wall and being supplied to your PC so it's cheaper to run and should run cooler.

Though I do agree I wouldn't use a 750w psu with a gpu that can pull 450w or more.

Edit: Doh! I go make a drink mid post and you make an edit! :p
Yeah, I was wrong, plain and simple. God knows why I've believed this all this time. D'oh!

We all learn new things every day :)
But you are right that 750W is not enough for 4090. For 4080 should be fine.

Someone mentioned Thor II 1000W. My unit(1st batch) only arrived with old 12pin 450W pcie cable. I asked and they provided me with 16pin 600W cable, but sense pins are just bridged.

So its not a true ATX 3.0 but it should be more than enough for 4090 - cable is 16AWG and psu side its 2x EPS, so it will easily sustain 600W(its within ATX spec for EPS)
 
The 4090 Strix OC recommended PSU is the Thor 1200 P2 (on the launch materials) but the tech. spec page for the 4090 Strix OC says 1000w PSU.
 
RTX4090 has shown up in Geekbench cuda benchmark. Scored 75% higher than RTX3090. For reference, the 3090 scores 45% higher than RTX2080ti in this test.

The 3090 is 40-50% faster than the 2080ti gaming, so perhaps the 75% is an indication of where average rasterisation performance will land

If the 4090 turns out to genuinely be 75% more powerful in raster than the 3090 then it would at least almost justify the price.

Will wait for reviews obviously, but that would be a hefty uplift at 4K.

It would take an uplift like that for me to reconsider skipping this gen, but I’ll still wait and see what RDNA3 has to offer at this point too before making any final decision.

It may be because Thor 2 1200W is not available, while 2 1000W is - they just want people to buy their available PSU ;)
Its a nice, extremely quiet PSU with braided cables. Albeit not ATX 3.0 and v. expensive.
 

Just seen that Gigabyte are going to release a 360 AIO version of the 4090. Looks like a step up from the 240 MSI Suprim AIO. No idea on availability though but I think Gibbo said before that AIO versions would be available in November.

Edit - Just seen a product listing for it on Overclockers page for £2299. Obviously if the pound improves on release it will get cheaper…….(sarcasm).

Does anyone know much about the Corsair cables that they are doing for their PSU? Every time I go to their page it says find retailers and OcUK is listed but I can’t see them selling it.

I’ll be honest I’m torn between getting the thermal take 1650w or just getting the 1600i.

I mean what if next gen they increase the power again, I assume that any non atx 3 psu might then struggle?

That’s nice man, I don’t know if I can wait until November though.

To arknor’s point above that is one concern I have about them if I’m honest. I imagine reselling in a few years maybe hard due to that too.

I would steer clear of this card. This is the same design as their 3090ti. Memory temps are worse than any 3090ti AIB(even air cooled), GPU temps are not convincing either. Waste of money over good AIB:

Maybe Gibbo can help here, I also want to know when I can buy the Corsair cable

I am assuming Corsair did the same thing as Asus, see my cable for Thor 1000W:
20221001-101226.jpg

Its 16pin bridged on 1 side and 2xeps 8pin on PSU side. More than enough for 600W. Ax1600i quality is miles above Thermaltake 1650W so I wouldnt worry about not having "true" pcie 5.0 cable
 
Afterburner's power slider is limited by what's in the BIOS.

That would be the largest Afterburner power adjustment I have ever seen by a crazy margin.

+35% on the power slider?
Jensen during presentation literally said you can increase power limit to 600W for overclocking.
If that was a lie, then I will just return FE. But based on materials Nvidia provided, you will be able to increase PL on FE to 600W.
Also - TPU(i only trust them and Vallosek) was on media briefing for 4090. They mentioned in the article that you can increase FE limit to 600W. So I believe them - there is no way to prove that until I get the card, hopefully October 13th ;)
