Cheap MATX build for 3080Ti GPU

[SeriousPigeon]

Hi,

I am looking for some help in speccing a cheap MATX or similar small form factor build for a 3080Ti GPU card that I already own. I am thinking AM4 Ryzen 7 8C/16T for the CPU, but I am clueless on MATX motherboards and cases. I was slightly bemused by VGA and DVI connectivity on some of the B550 boards I saw, I thought these went out with the dark ages.

The goal for the build is a small PC I can put in the lounge to power my Valve Index VR headset (hence the 3080Ti GPU).
32GB is enough for DDR and I already have a 2TB M.2 SSD.


I have -
Nvidia 3080Ti GPU
M.2 SSD 2TB
4k Display (LG TV in lounge)

I need -
CPU + cooler (would consider AIO watercooling if it would fit, but I guess this is unlikely)
Memory
MATX Mobo
MATX case
PSU for case

Thanks in advance,

Does it matter? I thought you were using the 3080 Ti? If it does, the one in my spec has DP and HDMI.

If you are not planning to use the IGP, swap the 5700G with a 5700X or 5800X.

The goal for the build is a small PC I can put in the lounge to power my Valve Index VR headset (hence the 3080Ti GPU).

Do this mean you have need of specific USB ports and sound jacks? The board in my spec has higher-end sound with 5 jacks and spdif and it has (on rear I/O) 2x USB 3.2 Gen 2, one of which is Type-C.

My basket at OcUK:

• 1 x AMD Ryzen 7 5700G Eight Core 3.8GHz (Socket AM4) APU with RX Vega Graphics - Retail (SKU: CP-3CV-AM) = £170.00
• 1 x Asus TUF Gaming B550M-Plus WIFI II (AMD AM4) B550 Micro-ATX Motherboard (SKU: MB-6J1-AS) = £139.99
• 1 x Corsair Vengeance LPX Black 32GB (2x16GB) 3600 MHz AMD Ryzen Tuned DDR4 Memory Dual Kit (CMK32GX4M2Z3600C18) (SKU: MY-4CL-CS) = £79.99
• 1 x Lian Li Lancool 205M Mesh Micro-ATX PC Case Black (SKU: CA-7B2-LL) = £69.94
• 1 x Thermaltake Toughpower GF3 850W Fully Modular Native PCIE 5 80 Plus Gold Power Supply (SKU: CA-1BP-TT) = £155.00
• 1 x Power Cable for Thermaltake GF3 850/1000/1200 Power supply (SKU: CB-000-TT) = £0.00

Total: £626.90 (includes delivery: £11.98)​

CPU + cooler (would consider AIO watercooling if it would fit, but I guess this is unlikely)

The Lian Li 205M supports a 240mm AIO, but seems like overkill for these CPUs?

MATX case

Kolink Citadel Mesh. You can move the front fans to the outside of the frame if necessary and they'll still be behind the mesh front panel.

Thanks for the advice. Yes, I don’t need IGP and it was only that I found it odd seeing such old display connectivity on modern motherboards. I have no actual use for them.

The valve index just needs DP1.2+, 1 x common garden USB3 socket and power (from its own DC supply).

Thanks, I’ll take a look
