Server power supplies are a different story.
They can actually do the 100% load where as the ATX can't.

Long story short: I bought some Chinese low quality PSUs and the Avalonminer 741 runs fine, but the PSUs are failing very quickly. I proceeded to buy https://www.deepinthemines.com/collections/power-supplies/products/bitmain-antminer-s9-94-platinum-1950w-psu-power-supply-complete-kit-120v-240v from deep in the mines and they are running perfectly.

The question here is: I can power the Avalon741 miners with only the one PSU of 1200W and the breakout board? Did I wasted that extra money Angry

? Also have you tried powering them with that same PSU (only the 1200W one)?

I have 240v outlets.

You need the AvalonMiner controller.

Are you certain I need the controller? I was thinking in setting up a linux server with CGMiner to have more granular control over the miners instead of using the Raspberry Pi.

Good to know. Thx again HaggsFIN.

Run it a day at -1
Run it a day at -2

Run it a day at 0

I found that with 240 volts

The hps-1200. Likes -1 best

Parallelminer has slush

As a 5% discount code.

I have an affiliate link you can pm me for it.

But the 5% code works without the affiliate code

Or with it.

There was a lot of psu issues with the APLUSPOWER power supply back in the Antminer S4 days, I would not recommend it.

You would be much better with the HP DPS-1200 FB A server power supply http://www.parallelminer.com/product/1200watt-psu-kit-for-avalon-721-80-platinum-high-efficiency-at-94-120v-240v/

You need the mains voltage 208 V or higher with this particular power supply.

Yup- I have 220 volts and a 30 AMP PDU.
Yes, I was considering the HP DPS-1200 FB A server PSU. Does it have enough extra watts to run an 1150 watt rig?

Reason I ask is that with ATX PSUs, most say not to exceed 90 per cent of the PSUs capacity.

Would this PSU work for 1 Avakon 741?

http://www.parallelminer.com/product/2466/

It has 10 x 6 pin PCI E cables. The A 741 only needs 6.

No.

Use invididual PCI-E cables for all connectors.

You should have one more modular PCI-E cable to use it in the power supply's "VGA3" connector

My simple tip is that if you have 220V or greater mains voltage, go with sidehack kit (HP DPS-1200 + breakout board and cables).

DPS1200 PSU Kit (S7/S9 compatible)

This kit includes one DPS-1200FBA 1200W-rates server PSU, one GekkoScience DPS812 board, and ten 18" PCIe double-ended 16AWG cables. Kit pricing is $80, a savings of around 10% over buying everything individually.
The DPS-1200FBA PSU is rated to deliver 900W from 120VAC and 1200W from 200-240VAC, but it's capable of better than that - I have run S4+, S7 and S9 miners off this supply. If you know what you're doing, voltage is internally adjustable from 11.8V-12.8V

PRICE: $80 each

If you have 110V / 120V mains voltage, EVGA 1300W power supply is a good choice.

You need the AvalonMiner controller.

Hello thanks a lot, any cheaper version around 50$ USD I can buy from amazon or ebay? so I must buy Avalon Controller ? for every miner? or? EVGA 1300W is over +250 USD too expensive need more options

the controller can run 1,2,3,4,5,6 easy

if you are a 120 volt guy this psu is good if you set the unit to -1

https://www.amazon.com/Seasonic-Power-supply-Supply-SSR-1200GD/dp/B01N7P5NSY/ref=sr_1_2?

Price 199USD Seasonic Power supply Power Supply SSR-1200GD too expensive Sad

got in I will buy controller as well. thanks for telling

If someone know good PSU 50-60$ range please tell me

if you are a 120 volt guy the answer = no

does not exist .

maybe 2 psu's I will look for a sale

thanks mate
LoL i have zero knowledge in this field how to know if I am 120 VOLT guy? Cheesy

usa = 120 volt for your wall receptacles in your house

much of the rest of the world = 240 volt for your wall receptacles

if you have 240 power the cheap kits cost about 100 bucks

but since I like to search 2 of these will do the trick and will use 110 to 240

https://www.newegg.com/Product/Product.aspx?Item=9SIA7GT5NN1424&cm_re=hp_power_supply-_-9SIA7GT5NN1424-_-Product

2 psu's will work

Guys. What about server PSU ?
I have ordered Dell 1200 MB A models. They have 80 Plus platinum certification. And output is 1400W.
Are they good for Avalons?

someone warned that 94% Platinum 1200W Power Supply Kit for (2) A4 Dominator Litecoin Miners 110-240v

1200 W might not be ideal to run Avalon 741

anyone running Avalon with this PSU?

I tried running two 741's with voltage set to 0 off the 2400 watt psu from parallel miner. It ran for a couple hours before glitching out. It was incredibly hot to the touch. Running one avalon per psu is obviously not a problem, but two would not work for me.
