Rockminer R-box power supply question - am I going to burn out my miners?

[minerbobbert]

I saw the AC adapter should have a 5A output, but it looks like the ones I bought for my new miners have a 6A output.

Will these be dangerous to use with my new equipment, or is the electricity delivered on demand based on what the unit draws? Just want to make sure before I hook it up....

Thanks in advance for helping out a newbie.

Tldr, no. Current is like a capacity, so you're putting 5oz in a 6oz jug.

Assume a few things. 

It is 6 amps  .  It was made  to spec.


The r-box pulls 38 to 46 watts.   

   So

 a 5 amp x 12 volt = 60 watts.     
 A 6 amp x 12 volt = 72 watts.

To run gear 24/7/365   your safety factor should be 75 to 80 %.


75% of 60 watts = 45 watts 

75% of 72 watts = 54 watts.

 Since I may be pulling 46 watts non stop.  A 5 amp brick is borderline   A 6 amp brick is not borderline (Assume they are correctly made)

If I used bricks to run my r-box units I would want 6  or even 7 amp bricks just in case.

 I run mine using an atx power supply  they use about 40 watts each and run very stable so far.
