Thank you! Both sides work. I have not been hacked like everyone else. Wink

GPUs are my favorite place to be with the resale value and what not.

Let me know how the dragons go. I have considered using a few ASIC miners for experiments.

Phil,

I appreciate the trust. If I remember correctly, you are using the gen 0 board which is the worst case scenario. Since then we have updated part of the layout and the dielectric compound to increase margins!

I have heard from a few source that some of the L3+'s can pull huge amounts of current from 1 or 2 pins within a small amount of time. I would error on the side of caution when using some less than ideal ASIC miners since fault protection cannot detect single pin current draw (that would be incredibly inneficient unless we were maintaining spacecraft or something as equally as critical).

Have you played with those at all?

-Optim

I have not ordered an L3. I was considering getting one and some one told me they occasionally pull hard current killing psus.

The hp 1200 which is a very good psu was fried by some L3s

So I have not purchased any L3s

For me I have drifted towards gpus due to the long warranties.

I may be getting 5 dragon mints this month.

I am busy working on a PID control deployment, but I have a competent sales team (though sometimes dramatic) that could help you out.

Wanted to see if these are still available. Probably would need a bunch. Cheesy

Nice! That mine looks clean!

You should add the image to the post so we don't have to move to an external link.

How was set up time? I've been putting together a FAQ on our website to help hit all of the more obvious question related to powering GPU/ASIC mines.

Yes. We still make these.

Images posted by newbies like me show up as a link instead of an actual image, as a way to stymie trolls, etc. If/when I've accumulated enough activity on the forum to no longer be classified a newbie, all my img-tagged images are supposed to transform from links into normal pics.

Setup of your equipment is a breeze, no problems. For those seeking guidance, I'd recommend attachment of both boards to the power supply first, then zip ties, then PCI-E cables with a support hand behind the board, then main power cable (not yet energized!) as a safe sequence. I can also imagine some people preferring to do PCI-E cables on the output board first, before even attaching it to the power supply. Some kind of plastic enclosure, as you mentioned you were working on in another thread, could be a nice enhancement if it ever works out. I'd certainly pick up some, as part of the Optimizer-approved package. Cool

We have a prototype of the enclosure, but the manufacturers are as slow as molasses. If you know of a good shop for form/molded plastic, do tell. I will update this thread with pictures of the prototype enclosure in about a day.

Thank you for the feedback.

Ya gotta start somewhere.... Here's a pic of my tiny (so far) farm, using three of Optimizer's breakout boards on three 2980W IBM BladeCenter H power supplies. I have discovered that the zip ties securing the input and output boards are not to be omitted. Been running for months solid.

Those are Optimizer's 6-pin PCI-E power cables too, at a *fantastic* price.

Super customer service as well, and quick to answer any questions.

Seems amazing.... Would we need to make all these to use or how does it actually work out....

I provide complete assemblies (and kits if needed).

It's pretty simple. Mount a 2880W power supply to whatever rack holds your video cards and plug all of the cards in via PCI-e cabling.

This is what is looks like on a 6 card GPU miner I am using with teh DPS2000BB variant.

This is a full view of the miner using a rack off of Amazon. The cables are supplied by myself or Sidehack on the forums.

I tied in and bolted the power supply to acrylic underneath the cards so that both may be cooled by my fans.

Here, standoffs are used to mount the breakout card so that it holds itself in place.

This is what the 2880W looks like with the breakout card attached.

My 2880W rigs are far away from me (another state) so I cannot show those right now, but I can show how those mount in these miners at a later date.

Thank you Phil!

By the way, here is a bump for updated stock. We have updated a few processes to catch any errors.

Lead times on orders below 50 are less than a week! PSU stock is limited.

Looks nice.

The prototype you sent in December of 2016 has worked for 110 days.

Zero issues pulling two thousand watts plus driving 2 Avalon 721s

Very nice item
