Not sure what are the benefits you believe you'd be getting. A single power supply represents a single point of failure. A large power supply is not easy to source. You'd also need special power plugs like NEMA L6-30P. But yeah, server power supplies are the way to go.

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.

Lol you don't know what your talking about 5000W at 12 v equals 400A at least.  That's 1 very expensive power rail you will need

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!

IBM BladeCenter 2880W Power Supply Astec AA23920L 39Y7349 39Y7364

you would have to make your own 220v power connection & use quick connects on the 12 volt lines

5000w of 12v?  Even if you can do that, are you sure you can cool 5kw in a small area?  A lot of home miners have to spread their miners around the home to avoid turning one room into an EasyBake oven.



5000w on 12v? Thats 416Amps! What kind of wires required for that PSU? finger thick? Is there a real one? Would like to have a look.

Also even if there's one, it may not be home friendly. It should require re-wiring as most of the 230v cables and sockets are only 16A max rated. So max you can draw from a power socket is 16*230  = 3700W

Why don't you add extra $40 to have the 1475W version?

Also, you do realize, that these have dual 12V rails, right? You will have to distribute your miners between 50A and 70A 12V rails. IMO, nothing can beat the single rail server grade PSUs.

EDIT: Get this one, if you hesitate to use the server PSU for some reason. This is the best you can get for buck, after the server PSUs, of course.

I've had really good luck with Minersource's hosting service. I sent an email last week when I had an issue and it was fixed in 15 minutes. They also emailed right back and let me know that they had corrected the problem for me. They host some of my bitcoin and litecoin miners.

OP you should look for some hosting services. They surely have lots of PSU sitting around, you'll just have to pay for the rent instead of acquiring all of brand new PSU.

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


GS

Depends on hosting provider and what kind of supply is needed.

We provide PSUs for all our colocation customers that need it, free of charge for the duration of your agreement

yes they do gawminers has some hosted deals .  I  did a thread on my hosted gear that i have with them  wait for a link

here is my thread:

https://bitcointalksearch.org/topic/m.7894701

here is one deal gawminers has.  

http://www.gawminers.com/products/13-mh-s-the-black-widow-by-gaw-miners-1-month-of-free-zencloud-hosting-service-24-hour-activation-asic-scrypt-miner/


it is an okay deal  you can use a cc to pay.   they run specials you may be able to get a better price if you check the website a lot.  I got a much better deal then this but they had a nice deal 2 days ago almost as good as I got.

what gear are you looking to run?


s-3's from antminer   use around 335 to 340 watts set at stock speeds.

  the evga 1300 watt psu will run 3 of them .  you will pull about 1050 watts.


here it is for 195

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1406297104&sr=8-1&keywords=evga+1300


here is a rebate form for 35

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1406297104&sr=8-1&keywords=evga+1300


your cost is 160 usd.  note the evga has a magic trick plug to allow the psu to power on instead of using a jury-rigged paper clip..


the s-3 costs .65 btc each.

 so 3 = 1.95 btc   that is about 1170 usd.  the psu is 160 after rebate.

 so 1330 usd  gets you   1325 gh pulling about 1050 watts.


 you will need 4 cat 5 cables and a 8 port switch  that is about 30 -40 usd more .

 so 1200 usd  total cost  for 1325gh    .  note I am basing this for usa buyers


EVGA 1300 was the ones I too was looking for. This is not available in my country. So I bought Antec 1300 Platinum. It has 4 rail 12v each at 600+ Watts and is very silent. This also has a oc-link feature where you can trigger/turn on another Antec1300 in tandem (havn't used it yet though).

you don't want to do that.  the zeus x3  units are not that good.   they are very power hungry.


here is a zeus x6 unit

http://zoomhash.com/collections/top-sellers/products/44mhs-scrypt-asic-miner-1000w-delivery-within-10-days-or-it-is-free


much better power ratings.

 there is an hp thread for a 2000 watt hp psu uses 220 volts it could run 2 of these.



here is a link for you--------2000 watt psu--------info

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!  Sad  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! Sad

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!
