GPU Upgrade

[Xaps]

I was thinking about a possible upgrade to my system, currently is a:

Ryzen 9 5900X

Lian Li Galahad 360mm AIO

B550 ROG Gaming A

4x16GB XPG D60 3600mhz

RM850X White

Lian Li O11D (not the XL)

9x Lian Li Uni Fans (Total of 12 fans, 3 bottom, 3 side, 6 on top push pulling the radiador)

 

I build the PC during the pandemic, but right after I lost my job. I was about to buy a RTX 3080 at the time.

Now I have the necessary money for an upgrade and I was looking to buy a RTX 4090 Suprim X Liquid (as you can see by the spec its mostly for aesthetic)

I did some testing and research to see if I was going to have to change my PSU and here is what I have:

 

The PC Part Picker showed a fixed 450W power consumption from the RTX 4090 and it got close to 760W total system.

All fans I use in the Quiet profile in Armory Crate.

Temps are close to 70C most of the time.

I wont be using 100% of the PC all the time, its just gaming and some video editing.

I live in Brazil and the price for this RTX 4090 is U$2728,09 if I was going to change my PSU the ONLY option I would have is throw another U$505,65 on a 1200W ROG Thor (And I would have the old PSU with no use and no one to sell it).

Also, I dont know how much it changes things, but where I live we use 220V and not the standard 110~130V.

I am okay with undervolting the card if necessary.

I was also thinking about the RX 7900 XTX or the upcoming RX 7950 XTX, but I really want to just set the games on High with RT and enjoy all the eye candy possible on a 4K display.

 

My question is:

If I'm going with the best setup possible without having to change my PSU, can I still go with this card? Or maybe another model of the 4090? (ROG STRIX White or Zotec AMP White, keeping it close to the White/Silver build)

If I go with this 4090, will I have to up the fans speed? That will make the PC consume more power and maybe get to close to the maximum PSU spec.

Depends in which games you wanna "enjoy the candy". Currently only Cyberpunk 2077 is worth the performance drop. All the rest which are supposed to support RT it's a pointless exercise in resource waste. And in Cyberpunk pretty much only the 4090 is able to tackle the RT, especially at 4k w/o the lame frame generation. As for the aesthetics - you can always get a watercooler RGB card and set the RGB to white.

I usually play the new AAA titles, TLOU, Jedi Survivor, RE4. I did play Cyberpunk alot and still want to go back once I buy the GPU. About FG, DLSS and FSR, I dont think I'll be using, I have used FSR for a while on a RX590 but it had lots and lots of problems and didn't like it (mostly ghosting and textures bugs), my use case would be all high/ultra if possible, 60FPS 4k native. If I wasnt going for Ray Tracing I could just get the RX7900 XT but, if any title comes out that really uses the tecnology I would end up regretting my choice. I just want a PC that will last me for the next 3/4 years and the RTX 4090 at least for now has that potential since it can use RT native, has enough VRAM for titles to come (I hope).

The fans wouldn't effect power draw as much as CPU GPU.
 

I'd say go for it. You should be fine. but you won't have any headroom.

 

I would look into undervolting the CPU and GPU anyways, you can lower a surprisingly amount of voltage before loosing performance or stability.

also lowers the temps which helps with everything.

Well bad news then - you need DLSS at 4k even on a 4090 to achieve 60FPS with RT on:

As to if it will last you 4-5 years - seriously doubt it. With Intel closing the gap in the GPU market and AMD practically neck-a-neck with Nvidia, i think we are 1 or maximum 2 generations from real performance boost where competition will seriously force them to innovate. AMD are about to launch 3D cache GPUs and if they have the success of the CPUs, well that 4090 might be obsolete in basically a year, similar to the 3090.

I could wait for the big jump, but than I could be waiting for a really long time (given that I'm using an old RX570 for now) and the wasnt able to play the most recent titles that I wanted. But since ThousandBlade said

I think I'll go with it for now, and later do a full system upgrade when this jump happens. I was just really skeptical to buy this GPU and having to change the PSU just for that (since this PSU is not even 1 year old).

Well i was also on a GTX 1070 and got tired of waiting so i pulled the trigger on an RX 6900 XT. But throwing $500 for potentially a year, where i know i'll make back most of that if i decide to sell it is one thing, completely another to spend more than 3 times that with no clue how much it will depreciate.
