Sorry bit of a noob question.

Looking to make a comprehensive list of all reputable manufactures, feel free to list the infamous ones too.

Here's a list of asic mining manufacturers for BTCitcoin: https://en.bitcoin.it/wiki/List_of_Bitcoin_mining_ASICs
By the way, if there's some infamous ones, then surely they aren't considered a reputable manufacturers after all and would be better if you wouldn't add them to your list.

In no particular order:

Bitmaintech (currently selling)
Avalon (last gen-ish A6, still selling)
BW (just announced they're not opening public sales until at least June)
Bitfury (lots of talk, no chips/miners as of yet available for sale to public)
Spondoolies-Tech (same as above but considerably less promising)
Innosilicon and subsidiary manufacturers (No recent news, should have their 14/16nm A3-based miner out this spring/summer)

I personally don't think now is a great time to be buying hardware, but to each their own.  The price on Bitmain's recent batch of S7's is very good, but I personally wouldn't trust a 1-fan design for cooling ~1400W of gear. As soon as anyone knows anything, you will surely find it in the hardware section here.

Rules of BitClub:

1) You don't preorder miners.
2) You DO NOT preorder miners.
3) Take dogie's guides with a grain of salt.

The ASICMiner Prisma used a much less efficient heatsink design to cool 1150W on one fan.

You will see a decent amount of prisma's with issues be it burnt blades or other issues.   They were not the best design I don't think.  I personally skipped the miner completely, and did not regret it.

And that machine is #1 when it comes to catching on fire and/or exploding.  That is something you don't want to be #1 at Smiley

I hosted 11 at one time. None of them caught on fire, but then they were in a 40F ambient room the whole time and I still had them suspended over a metal-wrapped shelf just in case.

One of the problems with the Prisma was a lot of air escaped out the middle of the endcap. If that was blocked off, it forced more air to go through the end of the heatsink and kept 'em cool better. Tubes had a similar problem.

Geeze that makes me feel old... Back in the mid 70's when I was in the Airforce I worked on some SCR switching power supplies for microwave xmitters - 10kw @ 5kvdc... Anywho the banks of scr's used the exact same heatsink design but 1 piece (a Wakfield part actually) vs 4.

Same potential problem of air bypass down the center. Perfect solution is a cone pointing inward for about 1/2 the heatsink length vs a flat plate blocking it. The cone creates a much smoother pressure distribution towards the fins, flat plate makes a lot of turbulence right where ya don't want it - at the heatsink exit.

I wouldn't exactly say that but -- they ARE strictly in it for the money. That said, yes there have been many that pushed things too far and definitely took advantage of a market that was biting at every Shiny New Thing they announced eg, AMT/Bitmine.ch, BFL, BA et al and I am sure that there will be others. Still definitely Buyer Beware of any new company that shows up.

For now, the only ones still standing with any decent reputation for delivering product after the past 2 years of scammers are Bitmaintech, Avalon, and BitFury. Love'em or loath'em, only Bitmain and Avalon make usable miners for the general public. I leave out Inno because of the A1 is now useless and anything based on their A3 still ain't there for the public. As for the SP50... Roll Eyes

I would not characterize the Prisma as reliable or a commercial success, nor would I the S7 as having an efficient heatsink design, but whatever. Time will tell!

All mining hardware companies pretend to make very reliable hardware to boost their image, then cut down on every cost possible to save money and still rake in a good profit. If only greed didn't do that to people, we might have good miners. There likely won't be new asic chip companies in the future as we're in too deep and there's just too much competition in the ASIC market nowadays with Avalon, Bitfury and the occasional Gridseed miner flooding the market.

Yeah, it's too bad greed is way more profitable (especially in a race) and hurts the survivability of a more ethical enterprise. Well, and a more ethical enterprise would probably be more conservative with initial capital so wouldn't grow to a substantial market share as quickly as the guys who take the big risks that do pay out (as opposed to the guys who take the big risks that fail, as the majority of mining ASIC manufacturers have done to the ruin of many).

 #2 to the Neptune actually. Which is STILL a bad place to be.

I said the S7 uses a comparatively better design than the Prisma which blew a lot of its air through the central core rather than the fins, as well as using bulk heatsinks rather than individual chips.

Bitmain and Sidehack have both created solid miners and have always delivered.

To date I have created and delivered exactly one solid miner. I am also not an ASIC maufacturer; they were Bitmain chips.
