New Hardware June 2015?

[amelen]

If you're going to buy current hardware, I'd recommend the Antminer S5 bought used. I've had luck on ebay getting them in the $300 range used using the "Make An Offer" system.

That said, I'm holding off buying any more tech until the S7s come out. Given the way the development has trended, I expect them to be in the 2-3TH/s range and probably at the same price point as the S5s are selling for new (sub $400 range for Batch5).

Purely speculation of course, but it's the path I'm taking.

Good idea. Speaking of S5's - do you know if I can run 2 on a single EVGA SuperNOVA 1300G2 or Seasonic 1250? We have an investor willing to fund a pretty significant hardware purchase, so I've been in touch with Bitmain Tech and they have been very helpful with info.

Look into server PSUs. You can probably get similar efficiency and reliability for cheaper.

Also look into breakout boards and nice PCI-e cords if you do.  It will make your life much much easier getting all the parts.

I think new equipment will be after June I foresee current equipment being sold during then.  But I could be very wrong.

I'm running my S5s, two per power supply, on a combination of EVGA SuperNOVA 1300G2s and Antec HCP-1300 Platinum 1300W power supplies. They work well on those power supplies, are decently efficient and the PS stays cool (including cool wires) even if I overclock the S5s a bit. My S5s are consistently in the 1.3TH/s to 1.35TH/s range with a slight overtune on these PS units and no issues at all.

Your doing what I wish all would do.  That is using quality power supplies.

It really does make your life easier in long run.  They are good for multiple miner generations.  And they save a little money compared to bronze.  Most should do this only reason I would consider using cheaper is if you had it already at your house and is decent gauge power cables.

Thank you! Exactly the info I was looking for. Thanks! Would you recommend one of those over the other or have they both performed similarly? Any experience with the Seasonic 1250?

I have not used that model, but Seasonic is a top notch company on PSU's so very good.  Both he mentioned are good.   

Honestly it depends on price if you can get the Antec he mentioned close to the EVGA I would go for the Antec ad get the platinum.  But decent pricing differen then I would go with EVGA.

Got it - thanks. The EVGA one is $169.99 now @newegg after rebate. Seems like a great price - I just wish it had 8 PCI-E connections like the Seasonic.

then do the second s-5 the same way.

Thanks for the info on the psu's Phillip.  BTW is there anywhere on the forums that has a psu round up?  I have not seen one.  Maybe I should check if the search is still broken   I got a corsair psu for my last computer and it is working great for several years now.  I never heard of Seasonic but I will keep them in mind for my next build.

all of the above are good psu companies.

I have Seasonics in my S2s and they do just fine. I got the EVGA G2s because they were on sale at Black Friday, so I bought up 12 of them. The Antecs are equally good, and I actually like their cables a little better. I have 8 of the Antecs currently. Not a single dead power supply amongst them. One of the Antecs had a bad 12V leg, but I turned it over to RMA and got a new one in a few days.

For me, power efficiency is critical. I've stretched my home and colo power to the most I can pull, so efficiency is key.

How cheap did you get them for BF?

I ended up getting the 1300G2s for around $100 each at TigerDirect on BF. I've since bought some other 1300G2s and some Antecs as either returned open stock (from Newegg), used (from Amazon and eBay) and I've had great luck with them all around.

Sounds like you are all set let us know how it goes!

Out of curiosity how big of discount did you get with open stock antec?  It sounds like I missed a deal

[denisbaldwin]

I think they were in the same $90-120 range when I got them. I have a TigerDirect near me so I got in there and look at their returned stuff. Usually marked down 40-60%.

Having in mind this low BTC price, I do not think there s much space for investment and development of new chips.

The entire industry needs to see price correction before new farms get turned on.

Ehh, the best time to invest is usually during "down turns". There are a bunch of case studies & white papers on it, but take a look at Intel & AMD for example. Their R&D investment is usually highest during down turns (especially intel). Granted this industry isn't as big, but I think the same logic still applies.

I would think R/D is a great time now.   Worst thing is btc is low so bad conversion time.  But overall good for the miner companies.

I think it is as there is not a rush.  It seemed before there was always a quick turnaround to get to the next generation.  Now they can spend smart and take extra time to make next gen chips (or just efficiency on old chips).    The first one with it will no doubt win the ROI war.  But they are all winners with low difficulty changes and miners running longer then a lot expected.

Is this what you were suggesting? Does it look like I did it correctly? The double cables are plugged into the back of the units. My hardware error rate is a bit high, so either the PSU is struggling or I didn't setup the cables the right away.
