Hi,i purchased 1 Bitmain Antminer s1 180gh/s-205gh/s but i dont really know what kind of powersupply these things need(dont know nothing about PSU's)

Is it possible to find a high quality PSU that can power severval antminers if i decide to buy another like 2 or 3 ?
Pls provide a link what is recommended.
thank you.
