Re: Which USB hub to use with Block Erupters | NanoFury NF1 | BPMC Red Fury? A List.
Time to add an ASICMiner Block Eruper 49 port USB 2.0 hub to the list 
Nice! I've added it to the Special Hubs section. However, I am still trying to find how much they cost by themselves to calculate price per port, or do you need to by 50BEs to get a hub?
Okay got this far and once again thanks. My next question is what is a safe load to run? If my PSU is rated at +5V 22A it should support 44 erupters. Now that is maxing it out at 110VA I know that cant be okay, so my question is at what capacity can I run this or any PSU? I was thinking of running 35 off it and two fans at 12V .85A so that is just about 80% of the +5V 22A rating. Also will that cause voltage drop because I am pulling more than 5A through an 18 gauge wire?
It depends on how well your ATX supply delivers on the 5V rail. I mentioned it before that I have 2 different ATX'es with 25A on 5V., and the older ATX model could power way more BEs than the new one.
You 22A ATX should be good for about 35 BEs (22A/0.6A = 36.6). Just make sure you don't draw more than 8A from a single 4-pin Molex and not more than 12A from a single string (though, again, depending on your ATX, you may get away with 16A per string). You will know if you draw too much, if some of the BEs will randomly stop hashing and light solid green.
