Topic: DPS2000BB Breakouts. New updates! - page 2. (Read 6958 times)

Aye, thanks for the additional info Sidehack.

By the way; by accident, I tested the DPS1600BB with my DPS2000BB, 2kW breakout.  That is also a viable solution here since pinouts worked there.

I don't recommend DPS1200 for L3+. Leastways I won't sell them to you if I know that's what you're using them on. The first five L3+ that came into my hosting, within a week three of them had set the PSU boards on fire. Looked like there was a flaw with the miner that caused potentially several hundred watts of additional power into one board, because every time the damage was centered around one pair of cables. The 1200 has about 500 watts of headroom over the L3+ stock power draw so it didn't trip overcurrent before the jacks started breaking down from the localized severe overcurrent draw. I could assume it's a flaw in the PCB, except that it happened to 3 of the exact same miner within seven days and not to any other of the same batch of boards, several of which I have powering S9/T9 off 1500W PSUs and they aren't even warm.
The owner of the miners said he saw similar trouble off pairs of Dell 750W, where one PSU would sometimes trip out (less headroom per supply). The L3+ are now driven off pairs of Seasonic 850W and I occasionally have to reset them.

My recommendation for the L3+, use no more than 1000W PSU and keep an eye on it.

My board works with the DPS800, which runs 800W on 120V and 1000W on 200+V, so that might be a viable option. I haven't tested it though.

But for safety I'm also not taking in more L3+ into hosting because I don't want my shop to burn down.

We are pretty busy but I could try developing those in time.  While you wait, why don't you guys go for the DPS2000BB breakouts?  I have a pretty large stock of those.

Also, cables are in Phil

I could use 2 or 3 myself.

Im looking for 2 initially for a pair of L3+ rigs I have coming.

How many do you need?  I played around with this design,  but ultimately abandoned because the power was too low for our stuff.

Nice.  Let me know!

Looking for DPS-1200FB Breakout boards...

yes all the cables run cool, i used my old knc miner 120mm fants on the breakout borads, will post pictures later tonight

Nice.  Thank you tlon19.  I expect all of the PCI-e connectors run farily cool at load on an I3+?

I don't suppose you have pictures of your rig you would mind sharing?

Also, edit above on cable pricing.  I initially posted the singles value.

bought some last week, works great!!! im able to power 3 l3+ with one 4k unit, overall very pleased.

I do not, but I will be refreshing stock on cables as soon as they comes in.

The 4k board works amazingly well for its construction!

I generally carry the 6P to 6P ($3.50 x1 and $2.95 x100+) and the 6P+2P to 6P ($4.00 x1 and $3.20 x100+) but there is an unusually high demand and backorder at the moment.  I have heard that Sidehack can fill that void when we are unable.

-Optim

my 2k from you are nice.

i prefer them to the 4k.

I will be looking to expand with my solar array partner. buy solar.

I will be need some 2k breakouts with wires

question do you have any 8 pin cables?

A few people have used the board for the 2500W solution and I have personally run a few tests there.  I have checked the pinout and it looks the same, but ultimately it will be your responsibility to verify everything is OK on your end!  This board is also rated for 2kW, but I am sure it will operate out of specification if you choose to risk that!  Monitor your temperatures during peak loads and verify the board temperature does not exceed 120C at ambient.

Each PCI-e pin individually can source 240W and we have tested under those conditions.

My team originally used the j4bb boards prior to using these cards and they burned out on us.  This is what we use in our rigs and they are open to the community.

We control voltages on the PSU directly.  For the DPS2000BB, we modulate the internal voltage on the supply pot to keep the board assembly process simple!

We also accept BTC if needed.

PM me.

I'm posting to show interest. Your 4K boards are compatible with both the DPS2000BB and the DPS2500BB? So if i understand correctly, since i'm having issue sourcing DPS2000BB, i could get DPS2500BB since they have the same pinout?

Also, do you plan adding voltage control, unless i missed it and you already have a solution for that?

And i would be interested in a sample, i'm totally willing to pay. I'm interested in these PSU's for GPU rigs to run them with PICOs. If you can sell full kits like Finksy i'd be interested as well.
Regardless once i have a full kit for the DPS2000 or 2500, i'd be inclined to post a basic review, if thats any interest to you.
I just need to research and pickup a FLIR, my farm is big enough that i need that to prevent burntout of connectors. Could be useful to rate experience as well. Maybe i can find a legit seller of one on the forum i could pay with Crypto.

Regardless of the little mention bits, i will have 800amps @ 240V to fill by 2018 so i will need quite a bit of server PSUs/BBs if i decide to go with these/Jabb's instead of my current ATX build.

reconnect,

Cooling is done separately from the supply.  Air flow must be supplied through the side of the supply with the rest of the miner.

The noise is based on your chassis cooling solution and how much power needs to be vented off

Hi Optimizer! How loud do these 2k and 4k power supplies get? Hair dryer or Vacuum cleaner loud? Thanks..

Oh, nice.  If you can specify the exact connector, that would be no problem.  I never mind adjusting outputs based on need!

Just remember, custom solutions take at least 2 weeks to source the PCB part of the assembly!

-Optim

maybe a 2000 breakout  and 4 six pin and 4 eight pin

let me check  what I need. for sure i will order on monday

Bump for updated stock.  Turn around is 1-2 days on orders below 50!  We have had zero issues on these boards!

We always welcome feedback for board updates!
