Topic: [Guide] Dogie's Comprehensive Power Supply Analysis - page 6. (Read 23236 times)

I wondered why he didn't just use Newegg 

well, it's kinda expected when someone's using url shortener.

i realized it since the first post.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         

It didn't make sense to link to hardware from all one vendor and at higher prices... until now.  I finally put two and two together.

OP contains Amazon referral links.

Didn't dawn on me at first to even check.  I believe in full disclosure so I am posting this information here.  

Also editing my posts in this thread back to their original info.  Because I'm actually here to help others without any promise of profit.

   Of course it's relative.   It might not be calculated that way, or intentional, or even intended bias.  But the TX750M scoring exactly a 1.0 relativity is what we call "not very statistically likely".  If it's a happy accident, I'm a monkey's uncle.

A human built the algorithm.  It's not infallible.   You have some obvious bias for Corsair.  There's nothing wrong their power supplies.  I own a ton of them.  They're great.  But there are equally decent and in some cases far better choices - especially economically speaking. Magically, they've been excluded from the list so far.  Unfortunately, the way the info is being presented, beginners might make the mistake of putting real stock in the "dogie score" and think it's a scalar difference between choices.  

FYI - some of your Corsair links are incorrect.  They simply lead to the wrong product.  I would have posted an update with correct links in a table as I did before but that wasn't very well received, so I'm erring on the side of caution this time around.

Lastly, I'll ask this again - who is the intended audience for this thread?  EU?  US?  Both?

Because the prices that are included with the Seasonic update are grossly incorrect for even the average price at major retailers like Newegg.  I'd recommend Hover Hound if you're not already using it.   Cases in point: Seasonic Platinum 760W was $100 (recently), is currently $169.99 currently, and is listed on this list as $199.99.  What's worse?  YOU SHOULDN'T BUY A SS-760XP2 TO USE WITH MINING HARDWARE.  Didn't someone already post in this thread to confirm at stock it WILL NOT WORK with mining hardware?  Oh right.  That was me!  

Back to pricing.  Since price is an inherent part of the algorithm, having inaccurate prices skews the data quite a bit.    Which is why I said perhaps a weighted average price or a high/low/average approach might be better.  I understand Amazon is usually a good common denominator for comparison shopping for a lot of things, but PC components are sometimes ridiculously overpriced there.

This is a good start towards a list, a very necessary thread here which I've glad you're working on, and a lot of the foundational work is there.  But it needs refinement.  I'd be happy to help, but last time I tried it wasn't all that well received.

Very nice doggie!!! Great job!!! 

Changelog 02/25/2014

• Added Seasonic range

Its not relative, certain PSUs can go >100 if they're excellent and excellent value. Its rare that the much larger PSUs score well as their relative performance per $ per watt is low. Its almost always cheaper and more efficient and flexible to get two 2x ~750s.

I don't think it's a question of "not liking" it.  It's a quality power supply.

It's the fact that the algorithm is taking price and perhaps other variables into account when computing the "dogie score".

My guess would be that the algorithm also weights all scores relative to one model.  That one being the Corsair TX750M currently.

Dogie, why did you not like the EVGA 1000W PSU? I ran 2 cubes and a BFL 60 single for 2 months on that thing and it was awesome. 2nd favorite is the Corsair AX 1200. Nice guide. Thanks!

I don't think that was directed specifically at me but in case it was by any chance all the power supplies I posted are confirmed to work with mining hardware.

The exception being the Seasonic SS-760XP2 which did NOT work with Cubes.  Even just a single, which was surprising but as I mentioned it's likely due to a protection issue rather than a lack of power issue.  The SS-760XP2 is a beast of a PC level supply.

Yeah. Weekly at least here in the US can mean a wide variety of prices.  

That's why a high/low/average might be more meaningful.  Depends who the intended audience is I suppose?

Thanks for your kind words Thats the problem with ASIC PSUs, providing 12-100A 24/7 is totally different than spike 12-100A. It takes a different beast to power an Antminer/cube.

It will be updated pretty often (likely weekly), but sites like Amazon can change every 5 minutes if they're price matching competitors.

Thanks SO MUCH for this post!! I think it really stands out next to your great setup guides. I'd like to caution others before recommending other power supplies be added to the list. A 'great' power supply in any other application doesn't make a great ASIC miner power supply. If it hasn't been tested stable for a few months on a Cube, Blade, Ant.. etc; please don't recommend it. I have gone through 2 other 'quality' power supplies that would do wonders in a PC, that have failed miserably within days at powering a single Cube. A 600w OCZ and a Cooler Master V1000 (1000w) both were not up to the task.
I just ordered 2 CXM750's to quench my thirst for power. Hope to have my Cubes up and rocking in a few days!!

If there was a tutorial section, I think you could fill it up alone.

And, as one of those taking up your time with PM's and you answering me in a very timely manner...
Thanks again!

Okay.  I suppose that makes some sense.  

But that's true of all threads.  If I go read a major Pool thread, I'm going to find outdated posts.  Especially on the first page.

The specs of the powers supplies aren't going to change.  Prices will.  To me in a thread like this that "snapshot" data might actually be useful.  Like, 9 months ago this power supply was $175.  Now in the OP it's $100.

Your ratings will change too of course based on the pricing.  I don't think you have plans to update those on a very regular basis.  Maybe a high/low/average pricing would be a better approach.

For me personally I factor in cyclical pricing on technological purchases when making hardware choices.  Especially since sales are typically very cyclical.

Its because when this thread is 9 months old, and the OP has been updated again and again, our random posts in the thread [especially 1st page] will remain old and out of date. I have the code recorded, thanks.

Not understanding the issue.  But okay, also done!

Is there some sort of SMF glitch with multiple tables?  

I figured I'd do it that way to make it easy for you to copy/paste the code straight into your table should you want to.

And your second one

This is a great thread and quite necessary.  I even thought about doing one up myself but because I'm so new I figured people might think I have some agenda or something.


This.  Big this.  Especially for people who want to later re-task the power supply for something else.

I'm only in the US market so all my info will be slanted towards that.  Specially slanted towards a ratio of performance and efficiency:value.  Warranty also important factor as well.  I also don't hesitate to buy products on rebate or refurbished hardware from well known suppliers so I'll throw that into the mix as well.  The prices I've listed are the "deal" prices; not necessarily the everyday prices.

Also I think some sort of number-letter coding for which mining hardware each supply is confirmed to work with would be very helpful.  Especially for n00bz.    Like maybe 3B if it can run 3 Blades or 2C if it can run 2 Cubes for example.

Do you want to list hardware confirmed to have issues of sorts?  For example, I listed the SS-760XP2 but at stock it will not keep Cubes powered on, even just a single.  Likely a no-load/overload shutdown protection of some sort that could be solved with a capacitor but I haven't that yet tested.


The table has been re-added. 

The information I had added was removed from dogie's "quote" less 24 hours after I originally posted it, which is apparently when it stopped "being useful".

I have since and will continue to update the pricing post above on a regular basis.  Much more regularly the OP has been updated since the inception on this thread.

If/when that changes, I may stop adding this data to this reference thread.  I've offered to collaborate to help dogie's OP contain more data in his format, but he seems disinterested in that possibility (read the thread for more info), so I've moved on and started to maintain and update this data myself for the reader's benefit.

Just got the Newegg e-mail.  The HX 1050W is currently on sale for $179.99 AR/AC using EMCPHHE25.
