Request for advice [Big Build]

[Mendeln]

Hello everyone,

Two friends and I would like to upgrade from the RTX 2080 to the RTX 5090 (although it's very expensive right now).
We have a budget of about €5,000 (~$5,680) between us.

Here's the PC built :

Case : be quiet! Light Base 900 FX Black
MB : MSI B850 Gaming Plus WIFI RAM: 32GB DDR5
CPU : AMD Ryzen 7 9800X3D / AMD Ryzen 9 9950X3D
GPU : RTX 5090 - MSI Gaming Trio OC / RTX 5090 - ASUS ROG Astral OC
RAM : 6000 MHz Corsair Vengeance CL30 (2x 16GB - Dual Channel)
WC : Arctic Liquid Freezer III Pro 360 A-RGB - 360mm
SSD : 2000GB WD Black SN850X
PSU : Corsair RMe Series 2023 RM1000e - 1000W - Fully Modular 80 PLUS Gold / SQ-GOLD Silent - 1200W Fully Modular - 80 PLUS Gold *PROMOTION*
OS : Windows 11 Pro 64-bit

We were recently offered a 4K, 240 FPS monitor.

This build would be primarily for gaming (to be able to play future games in the best conditions).
We are 3 so this PC will be used a lot for some long gaming sessions...

My main question would be :

• Would it be better to pair AMD Ryzen 9 9950X3D, 16x 4.30GHz with NVIDIA GeForce RTX 5090 - 32GB - MSI Gaming Trio OC ?

OR

• To pair AMD Ryzen 7 9800X3D, 8x 4.70GHz with NVIDIA GeForce RTX 5090 - 32GB - ASUS ROG Astral OC ?

Also, I tell myself that I don’t need a AMD Ryzen 9 9950X3D CPU for this purpose, don't you think so ?
I would like to keep the GPU and CPU at good temperatures...

Anyway, please let me know if you have any comments/suggestions for this built (and its gaming usage time per day).

Many thanks in advance.

The 9800x3d is perfectly adequate for gaming and whatever else you might throw at it.

AMD Ryzen 9 9950X3D Review - Great for Gaming and Productivity

The new AMD Ryzen 9 9950X3D brings Zen 5 with 3D V-Cache to the high-end. This new $700 flagship offers the best application performance, beating even the 9950X, and at the same time you get a fantastic gaming experience that's better than any other non-X3D processor on the market.

I don't have any specific input on the specific 5090 sku that you should opt for. You'd be well served by searching the reviews for them. Get the cheaper of the two if the cost difference is nonsensical.

 

[dgianstefani]

Get 64 GB of RAM and a better PSU.

 

[DirtyDingusMcgee]

Get an x870e motherboard too.

RMe corsairs are lower quality compared to RMx , shift or HX models . core reactor 2 is also a great unit for reasonable price .
also i would get 1 200w unit with rtx 5090 since it draws almost 600w from the wall while gaming and could have a short power spikes up to 700w .

you can opt for a 2tb drive , but i suggest getting a 4tb especially if 3 people will be using it for installing games and storage .
of course you can always add more drives down the road .
i second the suggestion to get 2x32gb of ram and be set for a long time , instead of adding more sticks down the line
(memory controller usually doesn´t like it when you have all 4 slots populated and may not run your modules at maximum speeds)

No idea what country you are located but that budget would allow you to build two nice PC's with 1000 euros to spare.

this is also true - 4K for a video card is crazy money
you can basically build 2 systems with rtx 5080 with your budget .

but i guess if you want the top of the line you have no other choice .

 

[DirtyDingusMcgee]

That was my immediate thought. 1 rig for 3 people? Time share? Split-screen?

That list looks very solid! I would go with the 1000W PSU as even the 5090 is not going to edge close to maxing it out. You may also wish to go with 48GB or 64GB of RAM, but that's not critical. Other than that, you're good to go! Cheers mate!

 

[Mendeln]

Hello everyone, thank you for all your valuable advices...

The problem is that I'm going to order from a specific website (the PC will already be assembled when it arrives).
The selection of components is quite large, but not everything is available.

So I'm going to upgrade the motherboard MSI B850 Gaming Plus WIFI) to an MSI Pro X870-P WIFI (is it really necessary for me and my usage to spend €150 more for a better motherboard?)

The RAM 2x16GB 6000 MHz Corsair Vengeance CL30 to a 2x32GB 6000 MHz Corsair Vengeance.

Regarding the PSU, there's a promotion on the SQ-GOLD Silent 1200W fully modular 80 PLUS Gold, maybe I should take advantage of it?

Several details make us prefer a single configuration on which we will play at separate times.

You don't really need it, but if you can get it for a decent price, sure why not!

 

[bonehead123]

^^THIS^^
and additional storage drives, as you're gonna need someplace to store your OS & gamz, as well as multiple back-ups of them, unless you are going strictly cloud-only, or just enjoy having to wait for them to load, and/or download them over & over again if/when something goes poopoo

Also, I'm not sure if it is still true, but there was a time when Vengeance ram did NOT play nice with AMD rigs.....but perhaps that issue has been resolved by now ?

 

[dgianstefani]

PSU peak efficiency at 50% load, 5090 alone can push past 600 W so 1200 W PSU isn't unreasonable. Besides, semi passive at lower load %.

I didn't say "unreasonable", I said they didn't need it. 600W would be MAX power draw under MAX load. The card will not be at that power level 99% of the time. Even accounting for other system parts, 1000W PSU is more than enough.

Corsair Vengeance's DDR4 XMP profile was very ill-suited to AM4, but they fixed that by offering Ryzen-specific kits later. If you're stilly buying DDR4 for Ryzen, then check it's the Ryzen version if you're looking at Corsair.

In fairness to Corsair, they weren't the only ones who screwed up - the very very standard Crucial DDR4-3200 JEDEC kit was a big mistake for me. I bought half a terabyte of the stuff in one go and eventually ended up fishing it out of the rest of the workstations and sending the whole lot back as unfit for purpose.

The best track record for DDR4 on AMD for me was Kingston, ironically. Honestly, DDR4 was a bit of a timings and stability shit-show for AMD from launch to close. If you knew what kits to avoid, or what timings/voltages would manually solve issues you were probably fine but I dread to think how novice PC builders found it after switching from Intel DDR3 platforms where you could just hammer any old DDR3 kit into any motherboard using a shoe and it would still just work every time.

 

[dgianstefani]

I didn't say "unreasonable", I said they didn't need it. 600W would MAX power draw under MAX load. The card will not be at that power level 99% of the time. Even accounting for other system parts, 1000W PSU is more than enough.

It's actually more like 650 W max draw, 600-610 W normal draw under full load.

If he's not using his GPU at 99% or higher utilization, he doesn't need a 5090.

That's just the GPU, rest of the system 2-300 W, getting close to that 1000 W.

There were 1000 W PSUs that tripped off 3090 Tis, which drew even less power.

 

[Chrispy_]

I don't know anything about SQ Power PSUs, but I certainly wouldn't gamble on PSUs for a rig trying to power a 5090, and I'd probably be looking at a 1200W minimum. The SQ Power 1200W might be okay, hell - it might even be excellent - but it's very cheap for a 1200W PSU.

A modern ATX 3.0 PSU is what's needed for newer GPUs. The older 1000W units that were tripped by 3090s were getting tripped by OCP on the momentary spikes of 900W+. PSUs have been refined, but also their over-current protections desensitised to very very short bursts.

Yes, a 9800X3D and 5090 should be fine on a 1000W PSU as that system is realistically going to pull about 800W, but the 5090 will still occasionally pull way more than 600W so it doesn't hurt to accommodate it with more headroom to reduce any risk of it tripping the OCP on the PSU.

My rule of thumb is CPU PPT + GPU TDP and add 50%. Having more PSU than you need isn't a problem, but needing more power than your PSU can supply is.

Again those are MAX LOAD conditions. Are you trying to say that ANY games can induce max load on both GPU AND CPU at the same time? Hmm?

That condition will only happen With Cinebench(or Prime95) AND Furmark running at the same time. That's just not going to happen. The OP just isn't going to do that. Ever.

Let's pretend, for S&G's, they do such a daft thing. Even then, that's only 950w max. Let's do the math here.. 1000 - 950 = 50. The Corsair RMe PSUs are well known for being able to sustain their max rated output for extended periods of time with no ill effect. But again, the OP never going to do something so daft, so it's a moot point.

Sure bud, only Furmark... that's why both games and RT testing at stock shows 600 W and more. Plenty of games will utilize all cores even if you aren't also streaming or doing literally anything else in the background.

Emphasis on "minimum".

 

[Why_Me]

Who recommends a 1000W psu for a 5000 euro build that includes a 5090? ATX 3.1 1200W should be standard for this build.

 

[dgianstefani]

Who recommends a 1000W psu for a 5000 euro budget that includes a 5090?

People with questionable reasoning and optimistic firefighting skills who don't mind their PSU fans at 100% whenever they do anything with their $5000 PC.

Not the place to save $50.

 

[Why_Me]

Again no idea what country the OP is located (it's a European thing) but either of these psu's would fit the ticket.

Are you done picking fights? News flash, that very graph shows VERY clearly that the recommendation is NOT the same as a requirement. It also conveniently shows what I just said above. Tada...

The system builder that the OP is buying from. I don't see a problem. 1000w is just fine.

Exactly.

What you said above? That only Furmark would draw 600 W? That wrong statement?

You seriously think a GPU that draws 650 W on its own should be paired with a 1000 W PSU in a build with a $5000 budget? Wow.

Blackwell, like previous architectures, is power limited, so where possible the GPU will bump up against its power limit. Hence the pros of AIB models with greater power limit adjustabilities.

Obviously at 600 W the 5090 can't be adjusted up, because 600+75 slot power means it's already maxed out for a single 12V-2x6.
