Topic: [PRICE REDUCED] DPS-2000BB 2000W Server PSU Interface Board - page 12. (Read 62077 times)
right ok thanks
I've had one running with a pair of Delta 80mm zip-tied to one side. A lot of folks that used these supplies in high-dense installations would stack two and use a pair of 120mm zip-tied across both of them.
We're looking into feasibility of selling a full kit with 12x 36" cables, the PSU, the board and a pair of appropriately-sized fans in a bundle, so I'll also be doing research on the options here soon.

do the psu's need the cooling fans attached like in the pic?
Yes, they need some sort of external cooling. I just got my order of PSU's in yesterday. Trying to figure out the best cooling solution, probably going to be some fans with lots of cable ties strapped to the side.Anyone have any functioning solutions that are decent and recommended?

Sidehack, thanks for the tracking / shipping update.
It's the same settings as on the D750 boards. We don't have a DPS2K doc up, but the D750 V0.5 doc on our website has all the pertinent information.
Question regarding dip switch positions on the DPS-2000 breakout board ...I think I may have bumped one of the 3 dip switches because the fan controller no longer works. The fans I have strapped to the side are barely pushing any air through the PSU, despite adjusting the knob. Are one of the switches supposed to allow for the fan controller to function properly?
Consider the expected DC power draw of each miner, and sum for the total DC output of each PSU. Divide by 0.9 to get an expected input AC power requirement to make that DC output. Divide that AC power by your available mains voltage (208, 240, whatever) to ascertain your input current requirements.
Fully loaded these PSUs will output about 2500W, which requires up to 11.6A from a 240VAC source. At rated output 2000W it's more like 9.2A 240V.
If the S3 requires about 350W of DC power, four per PSU would be about 1400W of DC power, so about 1550W (max, should actually be lower than this as at 1400W the PSU efficiency should be more like 92-93% than 90%) which at 240V would mean 6.5A; a set of four of these would then be at most 26A of 240VAC. If the S3 requires less than 350W of DC power (all the numbers I've seen are "at the wall", which is a useless number if PSU efficiency is unknown) scale your required AC current accordingly.

Yeah for 240V I'd recommend one DPS2K per 10A of circuit. If you don't overdrive them that should be enough headroom.
That's fully loaded with 6x antminers per PSU, right?In our setup we've got some APC 240v / 30a PDU's in the racks. 16A per bank or 24A total across both (2 banks per PDU).
I'm going to assume that if we make a "block" of 4x antminer per DPS-2000 we should be OK running 4 "blocks" per PDU? In theory we'd be right around the max for the circuits but a hair under. While we'd use more PSU's and boards, I think that would give us max density both in the cabinets as well as the PDU's.
Thoughts?
I prefer the being raised by an academician mother and a jack-of-all-trades carpenter father. Prepares you for all sorts of fun stuff, not the least significant of which are self-sufficiency and the ability to be useful in most any situation.
But yeah, if you didn't have that Youtube is a good fallback for on-the-fly instruction. I learned intarsia crochet from a youtube video one time.

Yeah 2000-2500W is quite a bit of current to pull off a 120V line. 240V isn't really that hard to come by if you know how to work a breaker box. I sometimes forget though, that regular people often don't have the same skill set that I grew up with.
That's what youtube is for.

Yes, we're still taking orders. We're still catching up to the preorders so we'd still be on "backorder" with approximately a one-week shipping delay, but we're still adding orders to the queue.
I don't have any PSUs. Minersource seems to have a good stock of them; I had someone within driving distance contact me about a pallet of 'em but they're holding out for approximately retail price and not really wanting to negotiate.
Thanks. Looks like you have to have a 200-240v circuit. That rules me out. I don't have any PSUs. Minersource seems to have a good stock of them; I had someone within driving distance contact me about a pallet of 'em but they're holding out for approximately retail price and not really wanting to negotiate.

A couple questions:
Are you still taking orders for boards and cables?
Do you have the PSU's or do we get those separately?

Anyone have a calculation of home many DPS-2000BB can be run on a 30A 240V circuit?
@ full power one PSU pulls about 8.6A (@ 238VAC)
2 PSU for same load is same AC load of 8.6A.
It is not how many PSU's attached to AC, it is the load on PSU's that is important.
EX: 4 2kW PSU for a 4kW 'load' would be OK as each PSU would be @ 50% of output power.
YMMV
Yeah for 240V I'd recommend one DPS2K per 10A of circuit. If you don't overdrive them that should be enough headroom.
30a x 240v = 7200watt/2000 = 3.6 round down to 3

Order received today, thanks for the quick shipping! I won't have a chance to test them out for a few days but hopefully I can get 6 S3s at default freq off of 1 PSU.
