A pico PSU is a small PCB that plugs directly into the Motherboard 24pin slot, and can power a basic system. It usually also has one plug for Molex and One for Sata to also power an HDD/SSD, but a very small total Power capacity, usually 120-150W. It's not needed for people like you and me who have regular 1000/1300W PSU's for their system.
Now, 2k or 4k server PSU's were originally designed for use with ASIC's and only have 6 pin GPU out ports and no 24pin output for motherboards or molex sata power etc. They are used in conjugation with low capacity regular PSU's (450W) to run the system off of. The picoPSU that Finksy is making would connect directly to one of the 6 pin cables from the 2k/4k power supplies, and thus eliminate the need for small PSU's to run the system, and upto 2/4 systems can be entirely powered by a 2k/4k server PSU.

I saw mention of PICO in this thread, something about it is a type of PSU or something that connects to PSU and motherboard? Will someone explain this a bit more?

Thank you again Citronick for sharing, all very clear and interesting as usual !
Do you really see an improvement using antpool ?

Thanks for the infos,
where do you go as 2nd pool , when NH doesn't reach 0.7 ? still F2pool ? Antpool or bitcoin.com ?

I use nh   and set

 p to .7


since correct number is .53

.7 is   1.32 bigger  which = blocks at 16.5 coins  I could give a long complex set of reasons   but


www.bitcoin.com  pools is paying 110%

and people are renting really high on nh  to mine on that pool.

by doing this they get 2 votes for btu  .

one on  nicehash and one on bitcoin.com

there is a strong move to go btu

I personally prefer BTU over segwit.


but coinbase  which is my btc to fiat  and fiat to btu  dealer wants segwit.

segwit does not work for miners.


not sure what is going to happen here.

I may need to cash out more coin soon.

apparently people who have tons of BTC can double their money fast by lending to desperate folks who don't mind borrowing with very high interest rates.....

I didn't dare to try it out because Poloniex can suffer a Mt Gox moment anytime.

I use Poloniex as a staging area and don't keep more than 1 BTC there.

Apart from convenience and fancy charts.

BTC farm is not in NH because....

1. no Tx fee sharing; the Tx fees nowadays is huuuuge!

2. Daily payout rate really depends on buyer-seller demand -- SHA256 aint that hot compared to Dagger-Hashimoto, ZEC, Decred etc.

3. No leverage on BTC conversion - since pool payouts are in BTC anyways.

4. Antminer S9 technically works best at their own pool -- I am convinced that they do some "voodoo magic" in their bmminer firmware. Hence, I would NOT point the Avalons to Antpool due to this logic. I maybe wrong but too many conspiracy theories on this matter and I rather take the safe and logical path. Sure I support decentralization etc. but I have power bills to pay too. The BTC farm consumes a massive power bill - I pay my Canada ISP pre-paid 3 months in advance to give me highest discounts. The power bill alone can power a small village for a month! Thanks goodness for cheap hydropower.

5. I dont make the decisions alone.... my group is not the easiest group of old farts to handle.

kinda off topic for a second
has anyone lended btc at poloneix?
if you havent they are paying a dumb amount of interest rates lately

I have moved all 33 rigs back to ETH due to my group's decision to hedge against possibility BTC Segwit vs BU drama.
Glad I did this move a few days back and got ethpool xNd fully ramped up ... 48 bucks - wow - who could have known!

So group's holding will be 30% BTC, 20% ETH and 50% back to currency.

Also, we recently signed a lease of another warehouse (next door - nice!); original plan was 44 x Pandaminers but I think we better go back to basics until Pandaminer get their act together - so I bought a box of Handyplast and getting ready for rig building again.

To be honest, building the rigs is easy. The part that takes the most time is the bloody OS installation (Win10 anyone?) and getting each rig stable - risers etc.

Lessons learnt from the 1st GPU farm:

1. Getting the electricals and cabling layout done right the first time. My current farm is a mess - power trips frequent when mining power hungry coins like ETH.
2. Getting the overall cooling strategy done correct the first time. Reduce the need of additional box fans etc.
3. smOS and SRR ~ no brainer ~ this alone will give me incentive to do the rig builds because smOS will save at least 50-60% of effort to get this farm up and running.
4. Last but not least... custom roms for low power (will stick to Eliovp's RX480 low power roms) - proven and tested.
5. Looks like RX480 8GB it is. At least for the first 20 rigs. If Vega gives me that extra value - good price to performance ratio then will get the other half of the farm to Vega.

Btw, I am thinking hard about using Pico+server PSU and rack-mounting like yun9999 for the 2nd farm. However, since the environment is a secured industrial warehouse.... we will standardize on open-cage format and EVGA-G2-1300w (for easier maintenance and RMA), H81s and TB85, Celeron 1840s, 4GB RAM (mainly due to smOS) and USB3 sticks. No SSD. Keeping it as simple as possible. Internet access will be supplied by the 1st farm.

Why not everything at NH ?

I pointed 20 x A721s (around 120TH) to NH for rental.... about USD$70-$75 per day.
Sometimes they will be a big fat order and it can touch $80.
However, I moved all A7s and S9s to PPS+ pools (PPS plus Tx fee sharing) for more consistent revenue.
A7s to VIABTC's PPS+ pool and S9s back to their grandfather's pool ~ Antpool PPS+

Phil - ensure you have #xnsub after port number; no spaces (..3334#xnsub) so that nonce subscription is enabled.
Latest firmware needed on S9 and A7s to support #xnsub

going to use it soon.

rosewill quark = very good
rosewill tokamak = really good

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=501   I own the 1500 watt tokamak
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=435   I own the 1000 watt quark the 1200 watt quark the 850 watt quark the 750 watt quark

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=441  I do not own this I own the rm1000i  also really good.


the capstone rosewood gold are not good.

if you get ebucks


http://www.ebay.com/itm/Rosewill-TOKAMAK-1500W-Full-Modular-Power-Supply-80-PLUS-TITANIUM-Certified-/172455843785?

this unit is 300 - 24 = 276  it is really close to the evga 1600 t2  which is a lot more.

im not a fan of rosewill other than their server case and hot swap cages

this is a good deal here

i actually had this power supply running 6 cards in dual mining overclocked at almost 1300watts

+1 mine too

so this is where my tb85 motherboards went!!!!!!
i was wondering who bought all the stock!!!

your actual setting ? 

Thx Phil!
I will contact you by PM if combined shipping to you and forward oversea to me is more interesting than direct shipping to me.
