Hello guys ,today i got my miner finally from the customers  Shocked , its my first time setting Bitmain miners,and i am going to buy the PSU now, so i just want to get sure that any PSU with 450 W will be good right? , also i will get an antena to make it work in wireless.

is there anything else should i consider ?

Thanks in Advance.

Bro get a bigger PSU.
Something like 600w+

You might want to overclock at some point.

Also make sure it is a good one as power quality matters a lot.
Get a Gold one.

Mine failed to boot up using a 500W. A fuse just kept blowing in the PSU. Everything fine using a 600W.

BITMAIN stated 360W, I bought a 750W for 2 miners. That makes me worry now... Are there measurements available somewhere? Normal and over clocked?

The watts in use is probably correct. ~360W@180gh/s or ~425W@203gh/s. There are multiple issues. You will have to take into account how many amps the PSU will handle per PCI-e connection. The cheap 500W PSU's I got could not even run with only one board attached due to the automatic fuses in the PSU that shut it down to prevent a burnout as they are not meant for that kind of load.
Using a 750W is really pushing it as you usually lose ~10% effect. You can take a loss of ~7% into account if the PSU is rated platinum which means you are left with about 700W, which is less than what's required to power two miners even without the overclock. You might be able to use it if you turn down the performance a little to reduce the total amount of power needed.
Does that 750W even have 4 separate PCI-e connectors?
