How do you like the Colorful vs the Onda? Those are nice pictures, I've had a hard time finding pictures of either board with the right angle and clarity to see how much space is between the GPUs. It looks like with the right kind of airflow either board would work for 8 GPUs (at least the less power/heat hungry ones).
Colorful pros:
- Can use server PSU as all it needs is 8x 6-pin PCIe power
- Fan power headers in the perfect place
Colorful cons:
- Slot spacing very tight
- Custom 4-pin to 4-pin CPU power cable
- Expensive DDR4 SODIMM ram
Onda pros:
Onda cons:
- Slot0 won't take a full length card
- Molex and Sata power connectors
- ATX power connector
- Fan headers not accessible with GPUs installed
- Expensive DDR4 SODIMM
The Onda V2.0 takes care of just about all the cons with V1.0. About the only con left is that you need a PICO if you want to use a server PSU since it retains the ATX power connector.
Let me add some little Comments for Colorful vs the Onda 2.0,
Colorful Pro
Colorful have special cable to power SATA HD from the board (supplier sent both CPU and Sata cables)
Colorful have 4 Fan ports
Colorful Posted from first boot and ran 8 GPUs without touching the Bios.
Colorful Cons
Colorful only has two USB rear ports which is pain in initial quick setup
Onda Cons
Onda was pain for me for first boot , only booted on built in GPU with no GPUs plugged until bios settings changed
Onda has only 2 Fan hearers
I have both. If the colorful said colorful and not k17 a knockoff.i would have ordered more.
My k17 uses a 2400 watt delta. Nice.
It is spaced tight . Since I run eight cards 7 1070tis and 1 1070
All are hybrids overheating is Not an issue..
Once I push this board to 1100 watts it smells.
I suspect there is a limit in the traces of the pcb.
I use the pass through this means all 1100 watts passes in the pcb.
I could use the server and bypass the pcb pass through . In theory this would limit the pcb to 8 x 75 = 450 watts.
I did play with the board and get 2 x 1080 tis power directly from the psu and 6 1070 tis powered with the pass through I pushed this to 2x200 + 6 x 125 = 1150 watts
Since the 1080tis did not use the pass through in this setup the board did not smell.
I think I can do 4 1080tis and 4 1070 tis using 4x200=800 and 4x125=500. That would be 1300 watts
Most of that would come directly from the psu.
In a perfect world I would use this board if it said colorful and not k17 knockoff.
In stead I stuck with the onda as I feel it can run 7 cards easy.
