Hello,
I have two ANT-Miner S1 need setup with new PSU. This my first time to dealing with ANT-Miner before. I buy only the miner. It come with nothing else.
How I need this to setup? What PSU you recommends for 2x ANT-Miner S1s? Seller suggest 1000W PSU. I think they pulling 720W?
Also need I anything else for the miners setting up? I have already router with WIFI connection and also ethernet cable for direct the plugging in. But what else needed?
Danke!

I'm using an 850W silver-rated Ultra brand PSU.
It runs two stock antminer just fine but only allows room for one Antminer to be significantly overclocked. The PSU fails with both antminers overclocked; I'm running one at 393 MHz and the other at 350 MHz.
I'd recommend 900W silver-rated at minimum to run both overclocked.
As long as you have the PSU and LAN cables, a router, and a computer, you have all you need to mine. There are a few antminer setup tutorials on this forum if you run into problems setting them up correctly.
Get a reputable one ase with miners it will work 24/7 so will need guarantee if it fails...
