Hi, I'm expanding my current RAID setup with 4 hard drives more.
4 hard drives sum about 40w more; I think I need to change my power supply, 700W+ power supplys are expensive.
Can I use a external power supply like the PicoPSU-120-WI-25,12-25V (56$) to power the raid 8 hdd's?
I have no experience with PicoPSU's. Can I use the PicoPSU without the 20/24 pin ATX power connector?
Thanks!
