GPU Upgrade

[cp_rosser]

Hi!

I bought the below spec in 2020 and I'm interested in upgrading the GPU. I use the machine primarily for Blender which I know to be GPU hungry.

Case	CORSAIR iCUE 465X RGB GAMING CASE
Processor (CPU)	AMD Ryzen 7 3800XT Eight Core CPU (4.7GHz/36MB CACHE/AM4)
Motherboard	ASUS® TUF GAMING B550-PLUS (DDR4, USB 3.2, 6Gb/s) - ARGB Ready!
Memory (RAM)	32GB Corsair VENGEANCE DDR4 3200MHz (2 x 16GB)
Graphics Card	8GB NVIDIA GEFORCE RTX 2070 SUPER - HDMI, 3x DP GeForce - RTX VR Ready!
1st M.2 SSD Drive	512GB PCS PCIe M.2 SSD (2000 MB/R, 1100 MB/W)
1st Storage Drive	2TB SEAGATE BARRACUDA SATA-III 3.5" HDD, 6GB/s, 7200RPM, 256MB CACHE
DVD/BLU-RAY Drive	NOT REQUIRED
Power Supply	CORSAIR 850W RMx SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET
Power Cable	1 x 1 Metre UK Power Cable (Kettle Lead)
Processor Cooling	Corsair H100i RGB PLATINUM Hydro Series High Performance CPU Cooler
Thermal Paste	STANDARD THERMAL PASTE FOR SUFFICIENT COOLING
Sound Card	ONBOARD 6 CHANNEL (5.1) HIGH DEF AUDIO (AS STANDARD)
Wireless Network Card	WIRELESS INTEL® Wi-Fi 6 AX200 2,400Mbps/5GHz, 300Mbps/2.4GHz PCI-E CARD + BT 5.0
USB/Thunderbolt Options	MIN. 2 x USB 3.0 & 2 x USB 2.0 PORTS @ BACK PANEL + MIN. 2 FRONT PORTS

I'm interested to know if a GPU upgrade is the best way forward, and if so, what should I buy? PCS upgrade section has options up to 4090 but I worry that space is an issue.

Any advice much appreciated.

Cheers!

It will depend on the specific model of GPU to some extent too...as an FE model 4090 is shorter (at about 304mm) than most AIB models (e.g. 355mm for the retail Zotac 4090; 329mm for the retail Palit 4090; 358mm for the Asus 4090)...and that case claims 300mm is the max GPU length that will fit.

The other watch-out for something like a 4080/4090 is your PSU...as they can both produce transient power spikes of double their claimed power usage, which can trigger a PSU's protection circuit. The experts on here have been suggesting a 1000w minimum and 1200w 'safe' level for a few months.

I just managed to fit a RTX4090FE into my iCUE 220T case, but I only have 5-10mm clearance from the front fans...and the thickness of the card means there's not much space between it and the PCIe add-in card I have my extra m.2s in.
