Hello Friends

I see lately many people are option to use HP Server Power Supply too

Is it safe and secure?
How would you connect your 6 GPU and Motherboard to it. I understand there is some connector. But how would you connect Motherboard to it.

Anyone using it here.

Please share best model for 1200W - Platinum

Thanks for your guidance.

i read from somewhere that you use 1 normal psu for your motherboard sata etc.
and the special server psu just for the gpu power. however you need to turn on the server psu first before starting up.
this is because the server psu is on as soon as you turn it on. the normal psu will only turn on when you press the switch on the motherboard.

Hello,

Here is a link for the 2400w 94% Platinum kit from Parallel Miner.  I am using these on my 8x GTX 1080 Ti rigs now and there is plenty of room on the breakout boards to add more cards.  I use the ultimate 2400w kit ($159) + ATX adapter ($34).  Using this adapter you eliminate the need for a 2nd power supply and 160w is plently.  On my rigs, this adapter powers the motherboard ATX slot, CPU power slot and an SSD drive and doesn't draw more than 40w from the wall.  Here is a link to order -

Are they providing 18 AWG Cable?

For 1200W.. they seem to not have it.

I am looking to buy from somewhere else..

What items would i need to connect Motherboard to this connector ?

You would need to 160w or 180w ATX adapter and that powers the motherboard, CPU and SSD.

How can i know which ATX Adapter is of Quality?
What questions should i ask the supplier..

They are of good quality and they are only $35 - so you could always order one and do some testing.  The support from Parallel Miner is pretty amazing.  Check out the discussions tab - I have worked with Joseph in the past.  He is very responsive and will generally respond via an email or phone call within a few hours of your request.

Here is a video of one of the PSUs in action -

Get a "160w pico psu" and get a custom cable made that connects to a 6pin pcie cable then to whatever other cables you need. Personally i got one made for a 6pin to 8pinEPS with a 16awg pigtail which i connected to the pico psu. Runs my mobo,cpu,ssd and some fans without any problems at all.

Which HP Power Supply model should i go with

I want to buy 1200 W.. Preferably Platinum

Thanks. Will check

I am also checking Chinese Factories too, as eventually everything comes from there... So prices will be cheap.. If you are planing to buy 50 or 100 Pieces...

It all depends how much power you need to draw and also whether you want to put two rigs on one supply and risk two rigs going down if the psu craps out. Personally one psu per rig for me (then again i have only one lol)

guys its called a pico psu which accepts only 12v which is supplied by the server psu, pico powers both mobo and a hdd/sdd.
ive got 2 full rigs of 6 gpus each with this setup, its nice and clean less wires going all over the place etc, soon to be 3 rigs
I use hp 1200w and 1500w platinum rated server psu's and yes its safe and secure, these psu's are little better and there made for enviroments such as we are using them in, they will last much longer than then atx psu counterparts, downside is these mostly all run on 220v only to get the full wattage

Thanks alot buddy, for the great response.

Now can you tell me the Model number for 1200W

Is there any model of PICO Power and Breakout Board? Can you share picture please.

Did you buy Brand New or Refurb or Used / Pull Out (Excellent Condition)
What did it cost you for HP 1200 W - Platinum ?

Thanks.

Hello,

Thanks  ( sry for my english im french)

Just get The 6 pin pcie Risers and u are god to go.

I have this one https://www.amazon.fr/gp/product/B072BJ3GCG/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
So I just need to remose sata cable and use one PCI 6 pin of the bundle ?
So I need 3 cable per GPU?

dps1200

flminer mods picos to power from the 6 pin off of a breakout board, and will soon be offering pcie cables: https://bitcointalk.org/index.php?topic=2040729.msg20310280#msg20310280

I try to snipe used/refurb on ebay/amazon but have been burnt by sellers on ebay (with good feedback) so be careful and always use paypal! Just make sure it is a cs (common slot) and pay attention to efficiency (I look for platinum). I try to find 1200's for $30, 1500's $100 (parallel miner's 2400w is a better deal than the 1500).

For breakout boards, I like the v7 x-adapter: http://www.parallelminer.com/product/x7-breakout-board-adapter-compatible-with-hp-750w-1200w1500watt-hp-power-supply/

There's 2 versions of DPS1200. One is DPS 1200 FB A, another is DPS 1200 FB-1-A.

You want the 1-A because it's platinum efficiency. The normal FB A version is just gold.


I just bought a set of the hp server psu, but the pico psu only has 4 pin cpu connector. Waiting for 4pin to 8pin cpu converter to arrive and will test it.

What price did you pay for the DPS 1200 FB-1-A ?
Its 579229-001 Model Number - yes?

Also there is another ones which is

DPS - 1200SB.. is SB ones good or FB-1-A?

Part Number on my two DPS-1200FB-1 A :-

P/N: 570451-101
GPN: 570451-001
SPN: 579229-001

They are the same on both psu's i have so must be related to any platinum 1200w.

Can you confirm are these very noisy ?

Or same low noise like ATX PSU ?

The fan runs at idle on the two 1200w ones and the 750w one I have. I did alot of reading up to see if they were noisy and if they reach 55-60c temperature then the fans ramp up but mine have never got that hot as I try to keep them at 50% load max. I have a blower style fan directed across the breakout board and into the rear of the psu as a precaution but its not really needed. I would say that its definitely as quiet as an atx at idle.

Thank You

As i was planning to get around 50 x 1200W HP Server Supplies.

So i wanted to make right decision.. and cost effective... as it will save good amount of money as compared to buy Corsair/Evga brands and buying hefty

Is there any issue if the HP 1200W Platinum Power Supplies are like 90% New and 10% Used... if those Chinese Sellers selling.. with warranty?

As buying Brand new these models i assume not available...  And would be pricey... comes around to same ATX Corsair/Evga...

Not sure where you are based but if in Europe try J4bberwock. I have various breakouts for the IBM 2880 and 6 pin to 6pin PCIe cable from him over last 2 years. Good quality and good prices. He has various PSU in stock as well as the breakout boards and cable.

Has anyone used Chinese OEM Power Supplies...

They mentioned its 80+ Efficiency Platinum.

Most of the branded Power supplies are now also manufactured in China too....

I believe its just the NAME..


Let me know your views.. if anyone using those Chinese OEM Power Supplies... they are using good quality capacitors etc..

Tell me, please, how to turn on the power supply - Delta DPS-1400BB. Thank you.

Hi guys,

Could we use an 1200 hp server supply for vega 56 mining?

I want to build a rig with 12 vegas. :) Probably will use an atx evga  750 watts power supply for Mb, ssd and 2 -3 vegas for example. And 2 X 1200 hp power supply for 9-10 vegas.

My doubt is, In the breakout board i have an 6 pin output.

My vega consomes 175 watts optimized and underclocked. But if wattman crashes sometimes they go to 2xx watts.  8)

Its ok to use this supply and breakout board with 6 pin connectores and  n 6-Pin Male To 2 x 8-Pin (6+2) Male PCI Express Wire 16AWG  anyway?

The 6 pin connector could handle this wattage, what is the limit?

Thanks

You definitely need to use 2 1200. It would be better to take the 2400W HP psu.

https://bitcointalk.org/index.php?topic=2616526.0

Just buyed 2 hp power supplys  of 1200 watts  and one evga 750 for motherboard and 2 gpus etc..:)  totally power from wall is 1750 watts for 9 gpus.

One strange thing happens, when i power on the system , sometimes the gpus dont start, and i dont see the fans running, and consequently they are not recognizes in windows if i leave this way. I have to poweroff and power on quickly and voilá. I have all the fdd cables connected to the power supplys and the same power supply for riser and gpu pcie power.

What could it be this?

Thanks
