Can I still use my current PSU?

[Nechtmarrie]

Hello everyone,

 

So i'm thinking about upgrading my current GPU an ASUS ROG 2080 TI OC to a newer model.

I was looking around and the ASUS ROG 4080 Super OC caught my eye.

 

I was hoping to find some answers regarding the compatibility of my PSU.

I'm currently using a be quiet! Dark Power Pro 11 850W.

The GPU reccomended wattage is 850W.

Will my psu be able to handle the new GPU or should I upgrade it to something like a 1000W for some extra reserve for other devices in my PC?

I use an Intel Core i9-9900K CPU.

 

Also i noticed the newer GPU uses a 16pin connector.

My current one uses 2x 8 (6+2) pins.

My PSU has no 16 pin connectors.

From what i found on the internet the GPU should come with an adapter to merge 2x 8 (6+2) pins?

The graphics card comes with an adapter cable included.

1 x Adapter Cable (1 to 3)

 

You can use your existing power supply. No need to replace it.

The PSU can easily handle the 4080 super, as it draws less than 300W in games, and you can get an adaptor for it. Though I would really consider the 7900XTX as it's cheaper, has more VRAM and has better performance in games

That CPU is a huge bottleneck to a 2080Ti in modern games on 1080p and a slight bottleneck on 1440p.

Pairing it with a 4080 is not advised. You're better off upgrading the platform and keeping the GPU if you're on 1080p or 1440p.

oh yea forgot to mention it lol. OP can get a way better upgrade for slightly more than the price of a 4080 super

I'm suprised the CPU fell off this hard in a few years,
When playing games I've never seen it go past 40-50% usage.
Or am I missing the point here?

The thing with the CPU for gaming is - the games usually use 3-6 cores almost fully and a few other threads lightly.

Task Manager and similar tools calculate the usage as the average of all threads. You can check how much each core is utilized.

The i9 9900K has 8 cores 16 threads, but the cores are at least 5 generations outdated. It's equivalent to a Ryzen 3800X.

Modern CPUs have way stronger cores. That's why, for example, a Ryzen 7600 (6c 12t) severely outperforms an Intel 10900K (10c 20t) in games.

If you want to detect the bottleneck, you can monitor your GPU usage, if it drops below 95% (without locking frames) there's a CPU bottleneck.

Or you can use Intel PresentMon and it shows if the GPU is waiting for the CPU.

Ah that makes more sence thnx!
I'm playing on a 1440p monitor atm and so far the gpu seems to be doing fine bottleneck wise..
When I run a recent demanding game it usually sits around 90-95% give or take.

So if i do end up upgrading i should probably do a new mobo, cpu and ram haha

I was hoping to be able to just upgrade the gpu but I guess due to the build being over 5 years old thats not ideal.

Yes, to utilize a stronger card you need a stronger platform. And with a stronger platform, you would get a smother experience even with the 2080Ti.

The PSU is plenty fine. I use a 750w with my own overclocked RTX 4080

 

I actually had a 9900k overclocked to 5.1ghz all core when I bought my RTX 4080 and it was a terrible experience.  I upgraded from a 2080 Super.

I had quite a bit of stutter in a few games and the overall gaming experience was not ideal, this was at 1440p.

I had a lot of stutter in ''Tiny Tina's Wonderland, Hell Let Loose, Dying Light 2 and Metro Exodus. 

 

I swapped to a Ryzen 7700x and the stutter improved dramatically and I gained some average framerate too!  Smooth as silk

The 9900k is just not fast enough to keep up with the 4080, remember its basically a Skylake CPU on steroids from 2015.

I mean price is a factor but most people if given the option would take a 4080 super over a 7900XTX.

 

It's close enough in raster whilst blowing it away in RT workloads and DLSS is a much better upscaler than FSR still.

 

7900XTX is a fantastic GPU but it's real advantage over the 4080 super is price and price alone.
