7800X3D + 4090 Build Check

Phunky · 23 Sep 2024 at 18:09

Looking at putting together a new ITX gaming build, I was going to wait until Zen5 and the 5XXX series but considering the poor release of Zen5 i'm looking at biting the bullet now instead (plus I can't wait any longer

)

Below is what i'm looking at and mainly wanting a sense check on the cooler with the case as i've never built such a small system.

My basket at OcUK:

1 x AMD Ryzen 7 7800X3D Eight Core 5.00GHz (Socket AM5) Processor - Retail (SKU: CP-3DT-AM) = £349.99
1 x Asus ROG Strix B650E-I Gaming WIFI (Socket AM5) DDR5 Mini ITX Motherboard (SKU: MB-6JZ-AS) = £239.99
1 x Gainward GeForce RTX 4090 Phantom GS 24GB GDDR6X PCI-Express Graphics Card (SKU: GX-20V-GW) = £1,799.99
1 x Lian Li SP750 SFX Modular 80 Plus Gold Power Supply (SKU: CA-79G-LL) = £119.99
1 x Lexar NM790 4TB NVMe PCIe 4.0 M.2 Solid State Drive (LNM790X004T-RNNNG) (SKU: STO-LEX-01454) = £229.99
1 x Kingston FURY Beast 32GB (2x16GB) DDR5 PC5-44800C32 6400MHz Dual Channel Kit (SKU: MEM-KNG-03166) = £129.99
1 x Jonsplus i100 Pro Mini-ITX Case - black (SKU: CA-01Y-JB) = £134.99
1 x be quiet! Silent Loop 2 360 High Performance CPU Water Cooler - 360mm (SKU: HS-01Y-BQ) = £119.99

Total: £3,124.92 (includes delivery: £0.00)

Also doesn't help that I keep switching between cases

I just want something small that can sit on the back of my desk out of the way.

The 4090 might get quite toasty in that little case. I wonder if it might be better to go with a AIO style 4090 (even if you have to switch the CPU to an air cooler) and use the radiator as an exhaust for the case? The 7800X3d runs very cool so it's not likely you'll have any trouble cooling that.

You ideally want 6000mhz C30 memory as it gives you a 1:1 CPU memory ratio,above that it changes to 1:2 becoming slightly slower in games.

Personally would want a bigger wattage PSU if you going for a 4090 and probably an atx 3.0 version which comes with the 16pin pcie3 connector.

Then theres the Nvidia 5000 series GPU being released before Xmas (hopefully) so something to consider

Gah... I think I may have to give up on the ITX it's just always such a compromise :cry:

and I bet it'll only end up out of the way instead of on my desk.

I won't be putting any mechanical drives in this, it'll only ever be for gaming, i'm thinking on the above now but will also look at some M-ATX builds.
