9070xt psu requirement??

[lockwoodcody566]

So im seeing 900w minimum and AMD not denying it. This doesn't make much sense. A damn 4090 or 5080 are recommending less. And this thing looks to be a reconfigured GRE...At this point if a new PSU is being factored into my price, either AMD makes it dirt cheap or i just go RTX and get the added feature set with my current 850w psu. Saw an argument saying its because it hits over 3GHZ. Well so does my 7900xt and on 2 8 pins with an 850psu and it has more compute units. Thoughts?

It`s said to have 260-300W TDP with two 8-pin connectors so it can`t have some monstrous power draw or they would have gone with three connectors.
850W PSU should be perfectly fine for it.

There is a model by power color with 3 8 pins and a 900w requirement that was leaked and AMD commented on it basically confirming it. No idea why it would need such a massive psu to have less units than a 7900xt. If i c ant get the best performance out of a card without this massive requirement its an easy pass. Because this tells me there is massive OC potential if its true, otherwise it wouldnt exist.

Yeah, that's nonsense, you can run a 7900XTX which can draw up to 360W on a *quality 850W power supply.

So if the max TDP of the 9070xt is around 300 you can bet that 850W will be more then enough.

The reason people always tend to get larger capacity PSU's is because they

a) want to futureproof when upgrading to another GPU later down the line
b) don't know the power draw of all their different components exactly since every build is different, so why not take the slightly bigger PSU just to be safe?

You're confusing a specific example and exception (a tricked out OC model) for the regular variants.

Just do a little bit of research next time:

Agreed my 7900xt pulls 390w with full power (XFX model) and only recommends an 800w on the box. Which is why this model existing is so confusing.

It exists for people with higher budgets who want an out of the box tricked out OC model and who have the larger PSU capacity to spare.

This isn't anything new.

Then why dont the 7000 OC models do the same....Yeah my 7900xt OC has a higher requirement but not nearly this. Theres nothing in the leaked specs explaining the high number. Boost clock doesnt explain it and also has less units than a 7900xt or similar. Youd think they would get MORE efficient not regress. Hi9ghly doubting its going to touch a 5080 or 4090 BOTH having lower requirements.

Well it makes sense. As they are starting to be more realistic about this.

For a 4090, 5090 or 7900 XTX you want at least 1000W PSU.

One reason it's suggested is if the CPU is a 13th or 14th Gen i7 or i9, or newer

Really unnecessary with something like a 7800x3d/9800x3d they barely pull any power. None of those GPUs suggest or need 1000w. Unless your doing a lot more with your PC and in that case you'd know it. Definately agree they take into account the higher pulling intel CPUs

[Illusion of Progress]

They typically recommend a higher wattage because they presume a PC with other power hungry parts as the worst case scenario.

Look at the 7800 XT; AMD recommends a 700W PSU but then they say that assumes a Ryzen 9 7950 or something.

https://www.amd.com/en/products/graphics/desktops/radeon/7000-series/amd-radeon-rx-7800-xt.html

"Recommended power supply for AMD Radeon RX 7800 XT graphics card is minimum 700W or greater with 12V output > 54A. Minimum recommended system power supply wattage is based on a PC configured with an AMD Ryzen 9 7950X processor plus typical power requirements of other system components. Your system requirements may differ."

In other words, it's a high estimate in order to be a safe estimate. A couple of people have mentioned success running the 7800 XT on 560W PSUs (though I wouldn't recommend that and would say a good 650W would be better to have).

If these are also models like the Hellhound or Nitro, they will have higher power draw allowances than typical.

All in all, it's unlikely you'll need 900W for a 9070 XT. If the 9070 XT does indeed have two 8-pin power connectors (I haven't kept up with the rumors on it to know), then a good 850W PSU will be more than plenty, and a good 750W or even 650W will likely be good too. But reviews will test this more accurately so we have to wait for them.

7900XT requires 850W and 7800XT 800W. i9 can draw 400W and a 7900XT 320W, so that's 720W + other stuff. You can run a 5600+7900XT on a 450W psu just fine as long the psu can handle transient spikes, no need for 850W.

My XFX 7900xt OC says 800w right on thew box and reference is less than that at 750 actually.
