More or less homebuilt, I cut and bent them up myself.

Thanks for the lead, but I think shipping would be prohibitive. Rough calculations show around $58 bucks at a minimum. 

New and used, over 20 available. I've finally torn down all my mining rigs, seeing if these have any interest before I get rid of them.







Starting at $35 per frame, plus shipping. All hardware, grommets, wiring, switches/leds included, plus six USB riser cables. Everything you need to assemble and stack rigs as shown in my picture above. Shipped "flat pack" for cheaper shipping.

Paypal or bitcoin, shipping from the Midwest USA.

Thanks for looking!

SOLD!

Thanks for the entertainment 

Jeee-zus.

Maybe if I just shout numbers he will change his mind about what he just said 30 seconds ago  

Are you in the Netherlands? If so, it is going to cost at least $76.00 to ship both of these to you. I might, just maybe, be able to shove them both into a large flat rate box with no packaging. That service will only set you back $58.65. International shipping is a no, pretty much however you look at it. Then we are still at a disconnect on price. You apparently have no reading comprehension, so I'm not sure what good PMing you will do.

Fleabay/feebay is fine, and there are bitcoin ATMs less than 30 minutes from my house. KCK is awesome, and I'm in no hurry for more bitcoins  

Last bump before going to e-bay, since people expect to get things for free here  

http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&LH_Complete=1&LH_Sold=1&LH_ItemCondition=4&_nkw=hx1050&rt=nc&LH_BIN=1

Selling all day long on e-bay for $100+ shipped. I've got top of the line shit here, with OEM packaging and purchase receipts. Minus e-bay/paypal fees (12.5% ish?) that puts them somewhere around $87.00 shipped, each, at the very least. Only way that would fly with me is if you bought both and let me ditch the OEM packaging, otherwise expect to pay more.

So, make a decent offer or beg for shit elsewhere. Thanks  

These things weigh a metric ton (10lbs+ shipping weight) and they are huge in the OEM packaging (16x6x9, for one) There are shipping calculators on the internet for overseas stuff, I'm around Kansas Zip code 66046. Thanks!

Bump!

Thanks, I've had nothing but great things to say about them either. Just wish there were more EVGA 1300 supplies when I needed them...

Lots are asking for proof of purchase for warranty stuff. I dug them out...

Bump!

Please keep your ridiculous offers to yourself. Easily $100+ on ebay, minus 12%.

Thanks!

I have two used HX1050 power supplies for sale, with the original packaging and all original cables/accessories. Pictured here is what I was using, the rest of the original modular cables are still in the boxes. Not pictured is the heavy gauge 110v power cables, which are included.



I'm looking for bitcoin only, please. Would like to get $90-100 shipped per supply (USA) but can work a package deal esp. if you let me ditch the OEM packaging for shipping.

These supplies were used for approx. 3 months of mining. Still in perfect shape and working condition. These two power supplies ran 6 R9 290's at modest settings, combined of course.

Please PM me with any offers.

Thanks!

I still don't entirely understand just what it is Mint is advocating, but I don't think on-chain exchanges are too far-fetched.

There's really no reason we can't see the entire records of an exchange, so why is it crazy to think the algorithm driving the trades and accounts not be "provable" like a dice game. Imagine if gox had something like that set up, whatever happened would have come to light much sooner. Security should not be an issue, or we'd have bigger problems to worry about. 

The model doesn't sound too crazy to me, "mining" could be rewarded with shared exchange fees, or it could potentially ride along bitcoin, as a merge mined chain. 

The only thing I don't understand is getting dollars to an exchange like that, outside crypto/crypto trading I don't really see how it could ever work. If ATMs, local trades, and things like pre-loaded cards took off though...

Dread Pirate Roberts, the manager of silk road, Ross Ulbricht, if you believe the government.

To avoid wasting time "1x jumping" I suggest running the cards direct, if they don't work right on the board a riser cable won't help!

I wouldn't try mining like that though, for obvious reasons.

The BIOS settings are different from board to board, you might google the particular part # for a guide, maybe.

Ah, yeah that may have had something to do with it! You mean the "+4" piece of the long 24 pin plug?

As for the video output, have you tried all three outputs yet? Try the onboard first, then the top card, then the last one, resetting in between each test. You may need to boot with onboard video, then change BIOS settings to use pci-e graphics. I'm not too familiar with AMD, only intel...

Those riser cables you have aren't very good, in fact they are just about the worst riser cables you could have got. I've posted my reasoning behind that in the past, if you want to go look through my old posts for technical stuff. Basically, x16-x16 is not needed, and just creates more unnecessary failure points. If you haven't already, I'd try without the risers. If it works without riser cables, you might want to look into a "1x pci-e presence detect jumper." Basically, tells the card to run at 1x mode. If the riser is on the edge of compatibility, as far as signal integrity, that might just be enough to make it work.

 

Your single 7970 will earn you about $5 bucks a day in bitcoin.

I started mining a long time ago with four 7970's. Today, I have over 50 GPUs hashing away, all from previous mining profits. My story is useless to you, because you are entering a totally different market.

You say "too detailed," but I say you haven't read enough. I have over twenty days of activity on my account, on this forum alone.

Really about all I can add to this...

Don't hold a duster can upside down, especially if you are spraying hot hardware. I'd imagine it would be easy to put stress fractures in heatpipes and heatsinks from the thermal shock.

That stuff is flammable, too. Hardware has the potential to set it off, ask how I know 

I recommend leaving hardware off and room temperature when using compressed air.

phillipsjk, you pretty much summed up what I said from what I can see. The passive PFC supply will loose efficiency when the line voltage is dirty, since it does not have the extra switching circuitry. From my understanding, the point of the APFC was a boost converter between the input capacitors and rectifier. Because of the input capacitors and the boost converter, the "first-stage" switching supply appears totally resistive, or nearly perfect power factor. To do so, it needs to have a pretty close eye on the input voltage and waveform, so since it's always adjusting, trying to match, it ought to be more efficient adjusting right along with "dirty" input voltage, right?

My logic is the "two-stage" SMPS should be sufficiently clean, no matter the input voltage, being essentially "double-filtered" by nature. Even a passive supply will be fine, still, though not as efficient as the active PFC supply in the same conditions. Basically, any "line voltage" correctors are not a worthwhile investment solely for the protection of computer hardware.

You seem to know a bit more than me in this area though!

A waste of money, nearly all ATX power supplies made use what's called active power factor correction. I believe this came from wikipedia...


If your power supply is gold rated, or even 80+ rated, chances are it uses active power factor correction. Basically, a switching power supply that is able to adjust to nearly any input voltage. At any given moment in time, the power supply switches it's total input current depending on the voltage. You can hear this "switching" if you listen closely sometimes  

Ripples in input voltage are not going to bother any good supply, but they will bother an active PFC supply less.

You may have seen passive PFC supplies, with the little red 110-220 switch near the line voltage socket. Those guys are not as efficient, so they are not as popular any more.

If you are going to mine, and you have not created a map of the circuits in your home, prepare to burn it down. Map, as in every outlet, non-moveable load (lights, fans, bathroom blowers, garbage disposals (bonus, those are usually branch circuits, extra current for free!)) and static loads. If you have a TV on the same circuit, and you plan to use it, take it into account on calculations.

If you are going to mine, and daisy chain a half dozen 750W supplies on a "surge protector," you're going to have a bad time. Pay attention to W=VxA and keep things in spec to the map you've already made. "surge protectors" are not bad, but misuse is.

On the other hand, pay attention to the other side of your power supplies. W=VxA still applies! Don't try and run 7990's on daisy chained 20ga molex connectors, as an example. Use this, if you don't know gauges yet.

http://www.bulkwire.com/wireresistance.asp

Understand how to properly purchase a power supply (multi-rail vs single, 12V wattage compared to total, outputs available, and how they map to separate rails etc..) Realize that properly loading an outlet and power supply does not mean using it to 100% capacity, try and stay within 80% on both. 15A 110V outlet? No, it is a 12A circuit! 1000W power supply? I'd consider it 800W, but that's just me.

Of course you should use quality cables between the wall and power supply. 14G is common, but 12G is best. Just because it's a fat cable, doesn't mean it's high gauge. Verify, and then check, check, and check again once mining actually starts. Be especially mindful of the plugs on either end, as those will likely be the failure point that gets hot. Even if it's brand name, watch it closely for some time. I really like non-contact IR thermometers for checking wiring, plus pegging cold/hot GPUs.

Understand that a power supply is capable of providing too much power sometimes, and that can really screw your calculations up due to efficiency curves. You won't really notice this without measuring, a kill-o-watt is a very wise investment...

If you burn your home, or god forbid apartment complex, down while mining there will likely be a sea of legal issues for you. Especially if you somehow daisy chained a bunch of supplies together, blatantly ignoring electrical code. Ignorance is no excuse, as with most things.

Be careful everyone!

As a programmer I'd think you would need to be deliberate and concise with things you do and "say" for lack of a better word? Guess not, huh?

I can stop at any time, you appear to be the one lacking in that regard. Again contradicting yourself in the same post. If you want out, walk away. Don't say stop, throw a few more stones and cry when I throw them right back.

What in the hell does the thread linked to have to do with anything. All I see is you stating more assumptions as fact, things you can't possibly know, then forming your super duper programmer logic on top of a pile of mud. In other words, the same thing you've done here! Bullshit speculation, clouded by an ego so large it couldn't fit inside a superdome.

ROTFL, asks a few questions and is smart enough to start assigning IQ's to people. You are a certain kind of special 

Wrong again,

Bitcoin coin generation does not virtually reach zero, it does reach zero. Quite a difference, really, but I'd expect as much from you.

Hol-le-fucking shit, people are dumb.

I like how you totally dropped the transaction time issue, once met with the technical difficulties of such a thing. Don't want to argue that point any more, either?

Thank the lord!

Oh, wait...


Well, that lasted a whole two lines of text, just like the last time you were going to finally fuck off.

Again, we are back to the mighty US government demanding anything on the internet, the same speculative bullshit you've been spewing forever. Somehow I guess that's different than my "broken arguments." Loosing badly, PM's? Whatever.

The world just lines up to do what the united states says. Especially now, after the world sees what we (US) do with control of the internet, or anything at all for that matter.


Bull FUCKING shit, you stupid bastard. What reason do you have to assume this will be the case? Unless EVERY FUCKING COUNTRY in the world empathetically agrees with the US, anything they attempt to do will FLOUNDER, as it does currently. Until that time, you are speculating just the same as I, except that your scenario DEMANDS impossible regulations, in both bitcoins and new currencies that may be exempt to new laws on technical points alone. How is a government going to regulate a new currency that DOESN'T EVEN EXIST YET, that possibly works in an inconceivably different way? How are bitcoins going to support the innovation in that area, if you can't move coins to an alt-chain without tainting them? Regulation on new currencies would kill them before they start, game over.

And that's just one massive hole in your "take over the world" theory. You contradict yourself, saying [your flavor of] regulation and new crypts will co-exist, it is not possible.


Tin hats, folks. Why the fuck are you here anyway, if you are so certain? Shouldn't you be digging bomb shelters, piling gold, and gathering MREs? Get the fuck outta here with your sensationalist bullshit, or at least post undeniable proof. You'll have to forgive me, but seeing your postings in the past doesn't exactly give me the utmost confidence in your "deep" research on who knows what. Can't even form a proper sentence on a regular basis, but calls the total financial seizure of the entire world by the USgovernment? Seems about right  


Let me ask you a simple question, is 0.2% ZERO? No? Wow, so you mean coins will still be made? Exactly like I said, eh? According to the chart you linked to, coins will be generated till 2136. Is that not a solid 100 years? Or are you going to argue the fact that .00000001 is not a coin. I'd bet you will, because that's your style. If 6th grade math isn't my style, what does that say about you? Least I can read numbers posted in a table, RIGHT IN FRONT OF MY FACE.

Next, you'll probably say that's not enough coins to generate to sustain, like a typical know it all retard, completely missing the fact I already addressed that issue previously.

Stroke that ego buddy, it must be nice to be so old as to know everything in the world so perfectly.
