Hello there,
I am installing my first rig. I have a question about powering, I'll be glad if you can share your comments.

- Inventory
1x MSI Z370-A PRO 4000MHz (OC)
1x Intel Pentium G4400 1x 8th Gen Intel 1151 CPU
1x OEM DDR4 Memory
6x Palit GTX 1050 TI Dual (OC) (85 W per GPU without OC) http://www.palit.com/palit/vgapro.php?id=2709&lang=en&pn=NE5105TS18G1-1071D&tab=ov
2x 500W PSU
(PSU One: HighPower ECO 500W HPE-500-A12S)
(PSU Two: Dark Force 500W DKPS500S1)
6x USB 3.0 Standard Riser
1x Add2PSU

I plan to use HiveOS or EthOS as the operating system, I will not connect the hard disk to the system.

Both power supplies have [one PCIe, 3x MOLEX and 3x SATA] power outlet. I will connect the SATA outputs to the risers.

However, as you know, GPUs also have PCIe power inputs. Is there any problem if I connect the MOLEX power outputs of the power supplies to the GPUs with a converter cable like below?

Or is there another option/recommendation?

Thank you so much!
