Topic: Best / Most efficient power supply for 2 Baikalminer Cube's (Read 1486 times)

Really hard to argue with that, I need to move to psu's like that, how many are you currently using / powering what?

Yeah needed a replacement T_T rolling now though!

https://youtu.be/M5hOIKzqikY made a quick video running the baikalminer cubes w/ the seasonic PSU

How do you tie that power supply into the other power supply? How do you make them start at the same time?

 Overkill but it'll work - and if you get a couple more cubes you already have power for them.

Did you " jump" the PSU, or use a antminer switch on the motherboard connector to the PSU?

It will not come on unless you do.

I think you are stressing too much over this. They draw 90w each, so 180w combined, maybe upwards of 200.

The % you are worrying about would be pennies or fractions of pennies. Stick with something that can output to 2 6 pin PCI-e and you're good.

Thoughts on this PSU for 2+ cubes?

 Most modern 80Plus rated PS achieve maximum efficiency near the 50% load point - but you then have to worry a bit about the extra cost.

 In your case though, a 400-500 Watt PS tends to be cheap enough to not worry about "too much PS" and how long the PS will take to pay off the extra capasity.

So I received my  Seasonic ATX12V / EPS12V 660 Power Supply SS-660XP2

and it does not power on . . 

how's shipping time with them and thanks for the link I guess I'm just comfortable with the ATX having not dealt with that setup before. What PSU of theirs would you recommend for a L3+ as I have one on the way or would you just rec the bitmain option

There's no reason to get a standard ATX power supply if you only need 12V rail.

Get this instead:

Same efficiency, less than half the price, higher capacity.

Thank you for all of that input, based off everyones information provided I've decided to use this https://www.amazon.com/gp/product/B009VV56U8/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

It looks like you already received some good recommendations, but here are the specs on the PSU you are looking at.

A bronze rated psu is at the low end of the 80% efficiency certification. It would be fine for a home computer that runs 3 to 6 hours a day without much of a load.

We are running mining equipment at full throttle 24/7 for months or even years at a time.  This would be considered enterprise duty.
The difference between you input wattage and output wattage goes to heat generation. SO the higher efficiency the smaller difference in input and output watts the smaller the heat generation from the PSU. We already have a ASIC or GPU that in the process is very efficient at converting the input watts to heat while hashing. Some people literally heat their house in the winter with their miners.
If the PSU is getting hot, then the connectors to the PSU are getting hot. Like I have seen the connectors go to 135, 145, 150+ degrees F, and start to smoke and then you have a burnt connector.  The hotter a connector gets the higher its resistance to the flow of current, and it gets hotter and hotter, etc.

Most down time on miners is PSU related.
 The ASIC is designed for 24/7 operation. The standard PSU is not.
The higher the efficiency and if you load is in the range of peak efficiency the less stress on your PSU even running it 24/7.
A server PSU is designed to run 24/7.

Obviously you load will be light with the 2 300 Mh/s Baikal cubes.

You did state in the OP "Best/Most efficient power supply"

94% efficiency and super low price. And they accept cryptos.

They say they are shipping my order next week, so i'll create a review thread when it arrives i suppose.

Are you running that and what does your setup consist of?

Why not get the DPS1200 server PSU and a breakout board and call it a day?

You can find more info here https://bitcointalksearch.org/topic/fs-gs-server-psus-boards-kits-stickminers-gpu-riser-power-made-in-usa-940317

hey no judgement here haha

Sure when I get home. It's just in my home office so a little ghetto set up

Can you post a picture of your setup?
