NO, don't do that!!!

Look at the one I am using. You get the two PSU's and everything you need to power the miners (except two power cords) for $119.00

You can use anyy type of power cord like the kind that plugs into PC's, monitors, etc. They are really cheap if you had to buy one. I probably have 30-40 around the house.

This is the one I recommend for you:    S9PSUKIT

   (If anyone has any thought or complaints about this PSU, let us know.)

Custom build using the X-Adapter REV 4. This 80+ Gold PSU kit is pre-wired and fully tested before shipping. Antminer S9 mining at full capacity will consume 1380watts at the wall in this configuration.

All components in this kit, including the PSU, are designed for 24/7 mining operation. They are many Grid-Seed adapter on the market. Only the REV:4 X-Adapter can safely power the Antminer S9 using household 110v/120V .

** Do not attempt this setup using other Grid-Seed Adapter or/and lower quality cables.

Kit includes:
(2) Original HP server power supply. (1) 750W (1) 1200W 80+ Gold 120v ~ 240v
(10) Pair 14AWG THHN PCIE cables

EDIT: Also, there is a power switch on each of the break-out boards on the newer versions along with a nifty red, LED read-out of the power.
