Topic: Best PSU to power two S1's (Read 5154 times)

I need to get out more?  From the user that posted -

 




All of those are ad hominem.  And on the socialization level of a toddler.

I've replied with facts and information.  You've replied with petty insults and a fair amount of ignorance.  Anytime I offer a reply of substance, you go the "TL;DR" (or TI;DR) route.  I won't apologize for taking time to reply or offer information.  I've done so in many threads, with no angle of any kind of personal gain or profit.

I have no issue with you doing as you please.  You dismissed the information presented simply because you didn't like it, agree with it, or understand it. Which is fine.  But don't offer accusations or aspersions against the presenter just because you don't care for the information.  As you say, let others judge it.  You've offered your opinion on it.    I'm not forcing anyone here to be anything except perhaps educated.  What they do and choose beyond that is there own decision to make.

I do find it hilarious you cite dogie's thread - a thread where he actually WAS clandestine about his purpose - and accuse me of doing the same.  Which I am clearly not.  I've left all the information open source, if you will, in that regard specifically for that reason.  I'm not looking for profit or gain in any of this, dude.  I'm here to help others.

For the record I "get out" plenty.  

My wife and kids would appreciate me at home more but I travel a lot for business, so it's a constant balance.  

Buy hey, you've avoided all the other facts, so please feel free to ignore those as well?  

Enjoy!  I'm actually wrapping things up here at the homefront for tonight.  

TLDR.

It's more like you're asserting your own ego to feel good about yourself in the guise of being helpful but when somebody steals your thunder, you get extremely defensive.  Just let it go, man.  As Dogie stated on his thread, you're taking this bit too seriously.  You don't get out much it seems.

If you have something to contribute, then by all means post it and leave at that and let the readers decide if they want to use the information or not.  That's what I did with my original post and that's what I usually do.  Nothing more, nothing less.  You, on the other hand, shoves it down our collective throats.  So go, get a hooker...or something...to get you to chill out a bit.

Well, as always, I tried to be helpful.  I'm here to help others.  And you're here... to?  I posted information to help others.  Information on solutions that I certainly didn't come up with, but that are vastly superior to your "free" (will they be paying you next purchase, if you use 3x rebate cards?   ) power supplies.  Not just initial cost-wise, but operation-wise with respect to energy costs.  In addition, I posted information via the link to regularly updated table where low-cost but high value mining-hardware friendly supplies can be purchased from major vendors.

Isn't that what this thread is for?  Seems so.  How is that spam?  How is that "covering [my] tracks after being exposed"?  Exposed as ...what?  Helpful?  

I'm gaining absolutely bupkis from any of this.  It's part of what makes this a community - the free sharing of information.

By all means continue to bask in your own ignorance unfettered from this point henceforth.  

Can't say I didn't try.  The horse was appropriately led to the water.  It died of thirst of its own volition.

Dude, buy a clue.  I'm not interested in your petty schemes.  You get that?  Why are you forcing the issue?  The way I spend my money/rebates is none of your goddamn business.  You're not my mother.  Stop spamming.

Dude, I already shattered your petty fragile world, hence your drawn out, discombobulated and desperate reply to cover your tracks after being exposed.

What`s the piont of this thread? A high end PSU is still worth a bit of money when the miner isn`t..

I use Corsair 850 to power 2 antminers without any problems.

Uhh... go back and read what you wrote in the portion I quoted and then read my response again.



Like I said if you're not familiar with the method of cashing out Rebate Cards for their full cash value, you're missing the boat.  Requiring yourself to make gift card purchases using those Rebate Cards is a backasswards philosophy.  

Rebates Cards = Cash.  Simple as that.  I could introduce you to the wonderful thing that is manufactured spending today too, but let's not shatter your fragile little world just yet.  


Not free.  That's the issue.  You're treating the Rebate Card as some sort of free money or coupon.  It isn't.  

You paid into a purchase to get it. You're then treating it like a free $20 bill you found on the street when you apply it to your next purchase.  See the error in that logic?  You're claiming a "low price" on the front end AND the next purchase using the same $20.  

Did you even click the link in my signature?  I'd venture to guess I spend more at Newegg in a month than you're probably spending there all year, and I'm doing upwards of $20,000 in rebates redemptions a year.  Not trying to brag or anything there.  Even my level of spending is stil considered small potatoes.  But I do kind of have a clue what I'm talking about dude.

The best deals out there per A/watt are generally those $10 or less per unit server power supplies.  A few people mentioned them in this thread.  They're server grade hardware designed to run 24/7 at high efficiency not Bronze like the CX500.  Multiple units can also be wired up to do load balancing across many mining end-points.  

There's nothing wrong with your route for a small time operation of a couple of S1's although the loss on efficiency does mean more in terms of an electricity bill.  But there are better and more cost effective options out there.

So if trying to educate people on how to purchase low cost hardware is spamming then yeah count me guilty.

What's wrong with my way of spending my rebate cards?  Are you just spamming?  I'm happy with the CX500.  None of them conk out on me yet and like I said, I get them for cheap (my last 2 PSUs was for free actually and I have enough rebates to get the next one for free again).  So what's the problem, dude?

Yup great recommendation.

Yeah.  You don't have to go that route dude.  At all.

Time to discover a place that takes payments near the second longest river in the world, my friend.  PM me if you need more help figuring it all out.

Rebate cards = Cash in your pocket for the total amount.  No flubbing around with keeping records of which card has what left on it.

As for power supplies on the cheap, take a look at dogie's thread.  There's a link to regularly updated pricing in my signature.

It's cheaper to get the Corsair CX500 (compared to a Corsair 750W or 850W for two S1s) to power each S1 at stock clock which draws up to 390WAC (usually around 385WAC) at the wall if equipped with a second high-volume "pull" fan.  At 85% PSU efficiency, the S1 demands up to 332WDC (390WAC*85%) from the CX500 which results in a 73% loading (332WDC/456WDC) on the PSU's +12V rail.  It seems there's some headroom if one is inclined to OC the S1 and push the CX500 a bit (I have no idea how much since I haven't attempted overclocking and don't plan to).  Having a dedicated PSU for each S1 also affords flexibility and the ability to avoid having more than one S1 to go offline when a single PSU ceases to function.  Best of all, ATX PSUs are PNP (no soldering needed).

The CX500 can be had for even less since the Egg always have $20 rebate offers and instant discounts (promo codes) for them quite regularly which could bring the actual cost to at least half.  Since I've been purchasing these PSUs since last year and have acquired a few $20 rebates from Corsair in the form of $20 Visa prepaid cards,  I've been able to get them at no cost at all.  The rebate cards have to be converted to Egg gift cards and apply them to the purchase.  Currently, there's no rebate offer on the CX500 at the Egg but the CX600 (with additional $12 off w/ promo code), CX500M (Modular) and the CX600M (Modular) do have it.  Here's a comparison chart:

Edit:  The "M" (Modular) version of the CX500 may not be ideal for the S1 as it has only one PCIe modular cable that cascades into two PCIe connectors that seem not long enough to cover the distance between the PCIe receptacles on each S1 blade (I'm not sure since I haven't physically tried them on).

I use a Corsair RM850 to power 2 antminer S1. Works perfectly.
2 miners draw 730W from socket.

I would suggest server psus'

Cheap and reliable.

I have used for many days with 24 overclocked S1s'.

If need info:

I see you have 50 antminers, about 10 TH/s if you run them at 200 GH/s each. Has this rig farm been profitable for you? How many BTC do you generate per day?

How about 120v? I'm using it with north american sockets.

Very nice setup btw!

*jawdrop* I love looking at mining rigs like yours "SHELF OF MONEY PRINTERS AND A TERMINAL"
I really need to get some real hashrate, my 20gh/s is a joke

the corsair 750 will run 2 ants clocked at 375 when using 220 no problem... i have many of them like that..  half of this rack is running the 750

I currently have a 3 Antec 850W - 80Plus Bronze, powering 6 Ant Miner Stock.

I was building servers long before miners, love Corsair.

Quiet, cool, 5 year warranty, cool ship logo....

The RM1000 is @ $199, will outlast your miner, comes with a proper cable for each board, and has a decent resale value:
