I'm running an RTX 3080 in the b450 tomahawk and had no issues.Looks like I'm settling on this unless I've missed something obvious.
My basket at Overclockers UK:
- 1 x Lian Li Lancool 215 Midi Tower ARGB, Tempered Glass Black= £61.99
- 1 x MSI B450 TOMAHAWK MAX (Socket AM4) DDR4 ATX Motherboard= £89.99
- 1 x Corsair Vengeance LPX Black 16GB (2x8GB) 3600 MHz AMD Ryzen Tuned DDR4 Memory Dual Kit= £68.99
- 1 x AMD Ryzen 5 3600XT Six Core 4.5GHz (Socket AM4) Processor - Retail (100-100000281BOX)= £239.99
- 1 x PowerColor Radeon RX 580 Red Dragon V2 8192MB GDDR5 PCI-Express Graphics Card= £199.99
The already have the GPU and will speak with OCUK to ensure I can hold on to it before returning it to ensure it fits and the issue is not with the GPU itself.
I have teh 550PSU as suggest by Grimley.
Will this lot work together?
In terms of future proofing it. Will the B450 take a 3070 or 6800 if I stick with this next year?
You may want more than a 550w if going 3070/6800 as you wouldn't have much headroom.
