Dual mini 6pin -> single 8pin
Dual SATA -> single 6pin
No!
See the link above!
Two MP SATA ports can provide 40-50 watts in summary!

So I thought so.
Sloth 75W
6 Pin> 6 Pin 75W
2 Power Sata> 8 Pin 100W
Total 250 W
the way you told me
Sloth 75W
dual mini 6 Pin> 8 Pin 150W
2 Power Sata> 6 Pin 100W ??
Total 325 W ??
and its only using 1 power sata for the 6 Pin?
SATA ports power connector are STANDARD.
3x1.5x12 is the standard.
And many members here do that for a long time already.
Your maths doesn’t consider the power draw distribution. The card won’t care how you power the 8pin. As long as it’s rated up to 150W. It may draw 150W from there.
You need to supply power base on the card’s actual power draw or potential draw. But not expect it will draw full 75W from slot, full 75W from 6pin, and only 100W from 8pin.
No one will design a card to do that. Why zero buffer on the slot, zero buffer on the 6pin, but 50W buffer from the 8pin? That’s just what you want, but not how the card programmed to do so.
Unless you actually measured the card’s power draw, and confirm that it will never draw more than 110W from the 8pin. Only using dual SATA to supply 8pin is very high risk to cause damage.
Thank you, I'll do exactly as you told me:
75W Slot
dual mini 6 pin> 8 pin 150W
2 Power Sata> 6-pin W?
Do you have any idea how many W's going to be with the 2 power sata >6 pin?
Yes, you are dangerously near to disarm the PSU. Remember that most cards don't use the full 75W from the PCIe slot, using most of the power needed from the PCIe power connector. People have noticed that the cut-out occurs around 110 to 120W from the PCIe AUX. This over the spec usage will greatly reduce the life of your backplane.Another quality thread. Just as an FYI, I have an MSI RX 580 Armor 8GB OC, which is rated for 185W power consumption, and I managed to get it working with a 6pin to 8 pin cable. My amateur observations with the system plugged into a Kill-a-watt meter suggests the card is pulling 150W more under load than at system idle, so I’m guessing this card is pulling just up to the 185W limit. Loads like Luxmark and Unigine run just fine. Sounds like I may be pushing it a little?

I'm using 2 x Mini 6 pin to 8 PIN male to an EVGA PowerLINK in bridge mode ( not directly connected to the MSI RX 580 8gb ) and then a female 8 pin to male 8 pin . . . to the GPU. this arrangement balances the total power going to the GPU.
( I had to use the PowerLINK in BRIDGE mode because AMD now has the RX 580's 8 pin power socket facing downwards towards the PCB. ) Actually, the arrangement allows a little more of the cMP's intake fan to pass just a little more airflow to the RX 580 8gb.
( NOTE : the other cables are for USB powered fans for the CPU tray area & the two M.2 Samsung 970 & 960 EVO blades)

Hello,
I have a Mac Pro 5,1 and I want to put a Vega 56 (300w) 2x8pin
So I was wondering how to supply it :
I'm thinking dual 6 pin + 2 sata should works but :
Do I mix 1 sata and 1 mini 6 pin to a 8 pin ? and do it twice
Or 2 mini 6 pin to 8 pin and 2 sata to 8 pin
Can we have one sata + one 6 pin to a 8 pin ? can the Mac Pro handle it ?
thanks

no the connectors on the backplane give you 120W (2 x 60W) stable
all over will burn your backplane someday
measured with load
no card, with load resistance
and the PSU shut down at 145W
with 10% headroom it is 130W
absolutly save is 120W
