I just received my new R11 gaming desktop with a 1 TB NVME SSD and a 2 TB HDD. I could not find the 2 TB HDD in file manager so I called tech support in case it was not installed at production. The tech had me open the case and the HDD was indeed installed. He had me swap the installed power cable with the pre-installed power cable for the 2 additional expansion bays and the 2 TB HDD started working. The tech said he would order a replacement power cable for me.  Well, it came today and it was the blue data cable that I didn't need instead of the power cable! So annoying after spending 2 hours with tech support already. I wrote back and I was referred right back to the help line.

Anyway, I am not hardware savvy so my question is whether I can just go grab a power cable and plug it in myself into the PSU? Is the plug in area of the PSU easily accessible?

Thanks in advance!
