ehh, I use those, sata to pcie on 3 gpus and it is fine. if they cant hadle ~50W than fuckem.
Is this safe/ok to use?
Many horror stories about those...
I am worried now!
Any more opinions?
If you can ... DO NOT USE SATA adapter.
SATA can't pull more than 45-50W and the PCI-E Slot can ask for 75W at max.
So if you can, use PCI-E 6 pin connector ... if you can't use MOLEX ... if you can't use SATA but you have to know what you are doing (check the power consumption of the PCI-E slot)
