You are taking the resulting wattage and not considering the input.

220v @ 20 Amps would produce 4400 Watts  (watts = Volts * Amps http://en.wikipedia.org/wiki/Watt)  So, to have a power supply supply 5000 watts of juice would require a 25 Amp circuit at 220 volts.

As I said when I started this thread, my goal is to power as many units with as few power supplies as possible.  To everyone who pointed me to Server Grade power supplies, I thank you for your input!

I wasn't aware Hosting Services provide PSU's.

It seems to me, pretty much any of the miners I look at, after I buy a couple of them, I'll fill up the capacity of a Power Supply.

One of the things I'm worried about is buying more and more Power Supplies as I buy miners.  For example, if I buy a Zeus Thunder X3 miner that consumes 1200 watts of power - I need a power supply for that unit.  Should I wish to buy a second Thunder X3, I need a second power supply.

What I'd like to do as I move forward, instead of buying lots and lots of PC based Power Supplies, I'd like to buy larger power supplies (maybe units that can provide 5,000 watts of 12 volts - or something...) and connect multiple miners to one larger PSU.  Except, I have little to no knowledge / experience with large Power Supplies.

Hello everyone!

I'm kind of new to all of this, and am trying to learn.

I've been reading a lot about people building rigs of GPU's, CPU's, ASIC's, etc.  In pretty much everything I've read, people seem to be using PC/Server Power Supplies.  Doing a lot of Google searching, I'm learning there are wattage limits to PC based Power Supplies.  I've found some really nice 1300 or 1500 watt PC Power Supplies.

As I look at some of the newer ASIC units, I see they are consuming upwards of 1200 watts PER unit!    If I was to buy these units, and wanted to use a PC based Power Supply to power it, I would almost need to buy one power supply PER ASIC rig!

The more I think about this, the more concerned I am with buying lots and lots of Power Supplies.  Instead of going in that direction, I'd like to think about buying higher capacity Power Supplies.

Does anyone here have experience with high capacity Power Supplies?  I've learned a little already and have learned bigger PSU's are 220 volts units.  But I have no experience in this area.


Any help would be greatly appreciated!

Got an ODD problem I'm hoping someone can diagnose...

Using the Hashra Controla v 1.4.0 image from the Hashra site, updated to 1.4.5 via the web console...

2 days ago, we switched our mining to LTC coins.  After updating the URL to point to and doing a Save and Restart, I saw only 9 of our 11 GridSeed miners come up  (Miners 1 thru 9 came up...).  The remaining 2 say "loading" on the advanced tab.

Last night, I pressed the web button to "Restart" and saw 10 of our 11 GridSeeds come up (Miners 1 thru 10 came up...).

Any ideas what I can do to get all 11 GSD's up?

I noticed it appears the Raspberry Pi seems to be using a specific program for LTC mining that's different from what it uses for other lite coins.


Thanks!

I installed ControlA 1.4.0 a couple of days ago on my Raspberry Pi and the unit is running well.

This morning, I attempted to log into the web interface (I left the defaults for the moment) and it simply stays n the login screen.  Any ideas other than resetting it?
