I am usa based I have 3 of them..


  One)   they will burn up most power supplies. -----------killed 2 power supplies

Two)  If you get a good power supply and run 49 sticks  you may over heat the hub. ------------melted the fuse supplied

it was a 40 amp fuse.   they issue is a 40 amp fuse will not blow but it will get hot enough to melt shit.  I put in 30 amp fuses and problem stopped.

Three)  If you are willing to run 35-42 sticks they are okay.--------   I now run 2 of them with 36 and 39 sticks each  no worries


here are 3 in action before I melted the 40 amp fuse
