I want to drop a note here commenting on these boards, the PSUs, the noise, along with my experiences with Finsky and Jabber.
The boards:
I received some of the first Finsky had I believe, Finsky can comment if he wishes on my versions relative to the vintage. I followed the instructions Jabber posted as a reference, but it is very simple and straight forward to hook up.
You do not need to be experienced with server power units, an electrical engineer, or even really electrically knowledgeable to put this together. You slide it on the end and use the small plastic 'pegs' to secure it. Once it is in place it is very solid. Common sense is truly all that is needed, but following simple instructions is advised if this is your first time.
I always tell everyone to be safe! Never take shortcuts, and never do things with the main power turned on, turn it off, but this is more about quality. It is there, and from talking with another home miner who purchased several more of these the next shipment was even better quality. So from a standpoint of getting what you pay for, this product stands up, and I should have already purchased more. I will be buying more and only hope they are still available
The PSU and noise:
It seems I am a minority regarding the noise because I enjoy the noise from all of my miners and PSUs, now the small fans on this 2880 are louder than my SP20s combined. No question about it, and no one has tried to hide it. I was told up front these babies are loud, and they are. I haven't ran any DB tests, but again, I have one unit powering 3 SP20s and the whole setup stays cool even when my ambients were rising. Today I am moving two of the 2880s to my bedroom which is where I like to keep the things I tinker with the most so I may keep a close eye on them. These have been running in my kitchen where I temporarily borrowed the 240 from the oven and stove (two separate lines on a 50 AMP breaker). I currently have two S4s, two SP20s, and a good bit of S3's I sleep with and know full well the 2880s will be the loudest. Without modifications they will be the loudest in your farm.
They are also the best power supplies I have worked with by far. The first one has run non-stop for about 6 weeks. I have driven it to 3150 watts clocking my SP20s as high as they could go. I think the 2880 would have gone higher, but I dropped the SP20s back from a pure power usage standpoint. If you want a total package power supply, use this setup. Top rated gear imo and I have a variety of server and standard ATX PSUs under my belt. Not only from mining but years in the Industrial PC and CNC controller industry.
This PSU with this breakout board is a beast in every aspect. The only thing I haven't bugged these guys with yet is running them in a redundant setup as I truly want a 55% load redundant setup with usage monitoring. I haven't bugged them because I haven't gotten to that point.
If you are disappointed for any reason it will not be the board in my experience.
The guys:
Fisnky and I chatted quite a bit during the purchase and after. He will do anything he can to make sure you are not only pleased, but he keeps you abreast of anything which may come up. He shot me a note to have me check specific items, he questioned my input power, and plainly wanted to make sure everything went smooth no matter what. Finsky obviously understands what customer service is, which is missing from many in our community. He did not want a problem to arise for any reason, be it my fault for incoming power, placement, noise, etc, or anything from the supply end. He is up front, and offered escrow of my choosing, and other ways for my security. In the end I simply sent him the coin because I felt there would not be an issue. IT wasn't over the top, fake, kind of salesmanship ala used car guy, it was genuine he wanted to put that product in my hands and help me make it function without delay.
Jabber is a busy guy, and I know he is involved in designing many projects. I did my legwork and read back, talked to a few folks, and I never found anyone who was not pleased with their deals. If you simply want to purchase the board talk to Finsky, there isn't a reason to bug Jabber if you are in North America. As you can see from their posts regarding the alternate fan placement they will continue to build on current projects. While some of us may want more from the current design, more of us wanted the board to run the 2880 in our hands as fast as possible. I have no doubt Jabber will entertain future revisions with different functionality but keep in mind he also has minimum quantities, and putting the initial designs, production runs, etc is not cheap. Neither of these guys should be losing money to make one-off designs, if you want something there is nothing wrong with asking, but be somewhat knowledgeable and understanding regarding your request and the response. I have respect for both of these gentlemen and as I mentioned, I have plans in place to purchase more products in the near future.
I apologize for the wall of text but I wanted to convey my positive experiences.
If you have a need to power a few miners, a couple of S4s, a few SP20s, or a lot of S3s or S5s, this is the unit and board for you. I have a friend who received cables as well (these were not ready when I placed my order) and he has the same comments and experiences I have relayed here. I call it the Total Package 2880 because it has become my go to power supply. Do not get me wrong, I have several other server power supplys of the 2000bb variety running happily, but when it comes to density, power usage, and counting pennies this unit makes the most sense today and for what I see next gen. SPtech have already told everyone their next gen miners will be big boys and made for industrial miners. No word on if they will include power units, and we know BITMAIN cannot provide a proper power supply.
I know what I have with my 2880s and these boards and I am very pleased. Going into the unknown next gen I have no doubts my 2880s will be able to handle whatever is thrown my way and that cannot be said for the average ATX powering the current gen. If you are going to purchase a power supply, you do not get what you pay for with retail ATX units, the pricing structure is ridiculous imo. I consider paying for one of these packages is currently the best way to go for a multi-miner setup today, and probably a single miner soon. Do your homework on pricing. People say the ATX variety are easier to sell later, but IF I decided to sell a miner with a power supply I would not include my 2880 and breakout board. It would be something smaller for that particular miner, and if it is a larger quantity sale then the customer should be advised that the 2880 is the way to go for that type of setup. Otherwise I am not doing that person justice in my opinion. You would have a hard time getting these out of my hands anyway. It would be much cheaper for you to order from Finsky haha because I love these units.
Thanks Finsky and Jabber, I appreciate your product, and the service. It is refreshing in a world of daily scams and theft to meet some of the few people who are legitimate business minded people with core customer service skills that only come from sincerity and roots in true customer service..
