Need a Reliable PSU

[ac130]

I am making a bitcoin (BTC) mining farm with 10 ANTMINER S5's.
https://bitmaintech.com/productDetail.htm?pid=000201412...

IMPORTANT: I don't have to pay for power so efficiency doesn't matter.

Specifications
Hash Rate: 1155 GH/s ±5%
Power Consumption: 590 W (at the wall)
Power Efficiency: 0.51 J/GH (at the wall)
Rated Voltage: 12V
Dimensions: 298 mm x 137 mm x 155 mm
Cooling: 1x 12038 fan
Operating Conditions: 0 °C to 35 °C

Notes
PSU: A power supply unit is not included, and you will need to provide an ATX PSU. There are 4 PCI-e connectors for +12V DC input and all four are required. Do not connect more than one PSU to the same hashing board.

I am going to be running these 24/7

Keep in mind that a lower efficiency PSU will ultimately put out more heat to do the same amount of work - so if cooling is going to be an issue it might be better to spend a little more and get a Gold PSU over a Bronze.

If you are going to use ATX PSU, then buy PSU with rated power 750watt.
If you are in US, find used server PSU, they are cheap & reliable.

Although power is free for you for some reason, buying a good PSU gold rated and above is important, you don't wanna fry or burn your S5 miner in less then a month.

Seasonic 760watt PSU is a good choice, you can choose either platinum grade or gold grade.

Ok I will try to go for at least silver+
Also is it good to buy a bigger PSU and then run 2 miners on it?

[Amph]

corsair rm line-up are good enough

If you want to pay less for seasonic you can also take XFX. These are actually rebranded Seasonics and are also cheaper.

[IITravel01]

For two, I'd look at the EVGA 1300 G2 minimum (pending Bitmain's specs. are correct), higher wattage if you can find one in the same price range.

You can buy 1300watt and run 2 miners with it, but I prefer 1 PSU per miner as it is cheaper and usually the psu last longer.

Note: Also I dont know if anybody have this experience but warranty for smaller PSU tends to be much faster as they have lots of stocks. And for big psu like 1300 watt and above, sometimes I have to wait like 2 months!!!

Thanks for the heads up.  Im going with 10 of these:  http://www.amazon.com/gp/product/B00K85X2AW/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A1CPWE4BUHBCWE
                                                                                                 (EVGA SuperNOVA 650G1 650W ATX12V)

590 watt X 100% = 90 % load
650 watt

Poor psu

[ProudMiner]

You should prefer server PSU, they are build to reliably work under heavy load, steady and constantly, the have high efficiency and industrial specifications.
Also the are very cheap because of low demand due to low usability.

check out this site http://www.gigampz.com/index.html
these are a 1000 watt 82A PSU, they are extremely reliable.
I work in the IT Department and these HP Proliant PSU are hard to kill.

There also 2000 watt PSU http://www.gekkoscience.com/products/IBM2K_board.html

Reconsider the whole idea!!!
If you MUST, consider used for best value.
I'm not trying to ruin your fun, I'm trying to save you some pain.

You mentioned grampa's hanger...
(his hanger or rented?)
I hope you have checked that the circuit can handle the load.
If there are also vehicles with fuel nearby take extra precautions about FIRE.
Will gramps mind if you slow cook his aircraft?
For siting considerations think of miners as 24/7/365 electric heaters.

I went with server PSUs. 92% efficient.
I started with hand did wiring.

The gekko boards are a good idea, I have some now.
They work for 1800, 2000, and 2500 Watt IBM PSUs.
2kW PSUs are USD $50 each used including shipping (ebay)
They are 220VAC ONLY and you have to buy cables and connectors seperately

If I were doing it again today I'd use the gekko boards and have CABLES make me PCIe power cables out of 12/3AWG outdoor extension cord wire.
I know better than to do it again today though!

I run a 4kW rail(2 PSUs @ 2kW) for each 2kW of miner.
Server PSU can run 2 or more PSU on each rail.
Disregard the double PSU warning if you choose this path.
Target PSU @ 50% of rated capacity.
That is the sweet spot for most PSU efficiency.
If one fails another can do double duty in a pinch.
@ $50 each I also have spares.

Every miner I know knows where you can get a 'good deal' on used HW, LOL


YMMV


EDIT: fixed 'some' spelling and added HW pron

[sidehack]

We've got plenty of those DPS-2000 boards still in stock. We do also sell PSU for about $35 (looks like minersource has some they're selling for $30) but we don't have too many left on hand. We've also got the Dell 750W server PSU, which would run one S5 pretty well and a full kit's about $50.

GigaMPZ's DPS-1200 board should be able to run two S5, but it'd be about maxed out on power. Server-grade PSUs are built to sustain loads like that but as tolip_wen mentioned, around 50% load is typically the maximum efficiency point so running 100% will probably suffer 2-3% over peak efficiency.

I have had very good luck with Corsair PSU's. I right now have RM 1000 and RM 850's. With the RM series you can swap cables if needed. Going with larger PSU's will give you more uses in the future as it seems total power requirement per unit keeps growing with new equipment.

[thomas_s]

The Dell 750W server PSU's are very good.

If you were interested in a break out board instead of soldered, send an email to support@minersource.net

[sidehack]

The Dell 750W breakout boards minersource sells are my Gekkoscience boards, so if they run out we've got more in stock. One benefit of a breakout board over soldered cables is, if the PSU does roast, the only thing you have to replace is the PSU. All the wiring stays put and it takes ten seconds to swap in a fresh supply. But those Dell PSUs are troopers. I've smoked exactly one in the last year or so, and that's after it ran 800W output for a week with basically no fan. Had one running outside that got rained on two or three times (while running) and it tripped out when very wet but always came back up with a power cycle. The fans on them are loud, but they'll push 450W with the fan on minimum speed (our boards allow fan speed adjustment) without trouble, at least in our testing.

can you get 7 volts dc  3 amps on an output  side or do you only get  12 volts.

I ask because the s-5 fan is monster loud via pm and if you

A) direct wire it to a 7 volt source it runs pretty quietly allowing for your s-5 to run at freq 337 or freq 343. with decent sound.

[sidehack]

If we populate the 5V buck circuit you probably could by using the voltage differential there. We rate the circuit at 2A for safety, but the buck controller is rated for 3A max. If you wanted, by changing three parts on the circuit I could probably make it output 7V constant without having to rely on differentials. I can probably test that out on Monday.

Do you know the actual power draw of the S5's fan at lower speed? If it's 3A at 12V it's probably a fair bit less than that when ramped down.
