I'd like some advise.

When all you big miners were little and say had a 750W PSU what second PSU unit would you suggest to buy for a complete future 6 RX 480 cards ETH mining?

So far I see ~850W Gold or Platinum with 4 PCI-e 8 pins as candidates. Thx

Uncle visited and said so sorry to hear you bought sh$t breaker boards Nhan, here's some money, go get the correct one as you dont want to be Deafened by the HP PSU.  Your wife n kids wouldnt want to live with you and the high pitch noise will drive your Dog insane.  







@Citronick - Yes I love my Simple Rig Resetter (SRR).  Sexy little invention and I will be doing a big order to support him.  He works hard and is always responsive whenever I have a question or issue.  Working like a champ, really love it but super Dilemma about losing my POWER button.  Wonder if I can use a splitter to be able to keep it and have a manual power on and off feature too.   Will email Tytanick.

Also just like you, I was going to sell my RX480 ref to refresh them with non reference, so glad I didn't.  The non reference 480 can be a pain in the butt.  My non ref 470 is super steady at 27MH+ and on low watts.  To get the 4GB 480 MSI to do that is a chore and different batches give different results due to different memories / ASICs.

@YSYLUNG - Not sure what you mean.  Maybe a picture would help but the PSU power chord face my SErver case rear which is the intake.  Unfortunately that is also the EXHAUST for the PSU so if I put another fan to help cool the intake side of the PSU, I'm pulling hot air from the GPU and pushing it thru my rear which is my intake.  It will be counterproductive.  Sucks.  I see your breaker board for the HP is different.  That one looks like it's easier to tape in a fan vs the lay flat, I can squeeze a thin fan in between but will look ghetto.  I can make an extender bar to mount the fan but I need to put this rig into the OVEN and see if the FIRE ALARM noise from the HP PSU will go off once ambient is above 90F.  My hopes are not high but if it works, would be great as it's very compact and allows different design configs or even cheap dual 1200W.

@ coinbeast - I would recommend starting small and get your feet wet before you start over investing.  When coin prices are high, everyone is GUNG HO but it can just as quickly drop in the opposite direction.  So make sure your cost is below average if you want to scale big.  Invest only what you're ok with losing.

@ deadsix - If you can return the MB, do so.  This MB is a pain in the a$$ and BIOSTAR support sucks.  I've only tried 4 MB out of my 15 and issues I've seen is enough for me to smash them.   For Mining the Biostar TB85 is good.  Cheap, no fuss and everything is fully detected by Windows / SimpleOS, no network driver or anything needed.  There's money left over to buy sexy LEDs to wrap around it.  =)

If you try reducing the core/memory frequency or intensity, does that increase the stability?

The Biostar Board is giving me stability issues after the BIOS update. I was running it with 4 cards earlier, now post the BIOS update I switched all lanes to Gen 1, changed Max Tolud to 3.5 and havent added cards yet.
But with the same 4 cards, my system freezes once a day. I had to switch to the secondary bios to get back to stability. Any Ideas?

I have spent the last day or two studying your new and old threads and you have finally convinced me to start using my BTC mining profits to expand into ethereum mining. I have been wanting to do this for a year or so but now I am 100% going a head with it.

Thanks heaps man, I appreciate it.

any interest in making a version that has 8 pin instead of 6 pin pci express?, I would totally be interested. would make things much easier on those of us that like to make custom cable and have a hard time sourcing thin enough jacketed wire. wonder why someone hasn't thought to make one with 8 pin pci express molex but set up as an eps 12v

i'm not really an amazon or ebay fan/guy. stay tuned, i hope i can get them manufactured with some add on & mods soon. now you can find them

ok, i really need to go get some rest. too much work/orders/projects. c ya'll later.

@yslyung talking about the breakout board for the HP 1200w psu, even though you have a different style. everyone else including myself can only find the style of breakout board that is horizontal instead of vertical like the breakout board you have on your hp 1200w psu's

if i have another, what would u do ? ROFL ! btw, i'm in the process of producing a newer revision, vertical with some mods & prolly some add on to it.







vertical or laying flat ?

tbh there is only one style for the hp 1200w psu, take a look on ebay and amazon, cant find any other style but the one that lays flat, I know because ive been trying to find something different from what I can find and so far NO luck rofl

will dig later, going to get some rest. nope not 1 style/pattern, the ones that i'm using are vertical when plugged in. look at the pics i posted in your thread. i just put the fan right infront, yeah it's thin but it does provide flow into the psu n cools the breakout board too.

try the cutting or drilling idea i gave you, i bet you it'll work & u can fit the bb's in n voila !

brb later, haven't slept much. *hint hint* i'm working on a "killer" 1 of a kind rig, i hope i'll be the 1st who "invented" rack/rig idea. parts are on order. back to drawing board.

I pre-ordered the old black Sapphire 480s Reference and got it delivered after 2 weeks after Polaris sale announcement.

I wanted to sell them mid-last year and get Sapphire 470s but I ran into electrical problems in the warehouse - I messed up my cabling on the 3 phase power due to hosting more ASICs for my other team members.

So didnt sell them (with Nanos).... oh boy I am so glad I didnt, it turned out that those Fury Nanos was absolute killer for ZEC. And there wasnt anything terribly wrong on the old 480 Refs.

To be fair those 480 Refs with blower fans never did give any problems except for the turbo sound at full speed but wth its a warehouse, the crickets wont be complaining about the noise.

I am 90% maxed at the warehouse and reached the power bill amount that I can afford. All the 480s and Nanos are zapped with low energy and -100mV roms by Heliox.

Btw, the SRR is a god-sent; I have never seen the farm with near 100% uptime like that during Windows days. The last 48 hours, ZEC mining was all time high and SRR kept up the rigs so well.

@ysylung - Let me see a closer picture of your breaker board and the HP 1200W.  It looks the same to me as there's really only 1 style / pattern of breaker board for this PSU even with different revision and models as it have to lay flat.   The Fan I'm using only consume 9W and is pretty powerful.  The empty space between the breaker board cabling and the intake is quite thin, I'm not sure if any fans would do the job in between but would be nice if there is.  I would like to see your fan placement for it.  The heat is not from the GPU, I can have this thing on the side and it would do the same.  I will have to MOD my rigs to support ths.

For the server case, the intake comes from the rear and push all cool air across thru the front. I need a solution for it, otherwise will stick to EVGA but I was like damn, I can fit 2 of these in easily and get as much power for any GPU I want.

@ Marvell1 - I would prefer to return these to NewEgg then to give your or others headache with them.  Two of them will require CMOS clearing plus BIOS flashing to support the cheaper CPUs.  Not hard but why the heck do I have to do all these extra steps.  1 board have 1 bad slot and 1 slot that if you plug anything in, Windows won't boot.  1 board the LED for the boot up status is dead.  I would have been willing to deal with the hassle if it worked with Simple but it was giving me too much issues with more than 1 GPU with simple.  I'm just keeping 5 to play because I absolutely love the LEDs.  Just when I ask to not quote the long pictures, you did it. HAHAHA   

Agree with you on RX470 being so different even with the same cards.  The Sapphire 470 Nitro I bought when it first came out is completely different then the current version.  No more LED, the plastic is cheaper and they have so many RAM variations. However you just have to keep a few different ROM vs trying to keep 4-6 different ROM per card type (Mem shift, Power Save, OC, etc). I just bought these different Play cards and the fact that they are all different means more time to flash, figure out what works and is a headache if I run Mix cards in a server case where I can't see what I have.  I don't use GUI to flash as that's too time consume and you have to unplug PCIe which will ruin it over time.  Doing 3 at a time via GUI for a 7 GPU rig is way too time consuming especially when you have many rigs and at times would like to switch between ZEC and ETH roms.  Standardization allows me to FLASH quicker, RMA quicker, know of all the bugs that goes with it as I will have more experience with it.  When you're running over 400 GPUs, I don't think you want to deal with too many vendors.  You stick to the good vendors that provides good RMA services and support as every week or two something will surely fail at this scale.  I also agree with you on the original Ref 480.  Those were dream cards, the new ones are CRAP.  I'm ready to smash my MSI Ref 480.  Only 6 out of 10 are good but they can barely do 26-28 not like the old ones.

Damn guys, you're giving me too many ideas, stop posting such awesome stuff >_< (nah continue but i hate you  )

1 of the reason is the breakout board design for the HP 1200's that you are using atm. it's blocking the intake, well not entirely but i guess every bit helps. double side tape a fan in front of the intake would be a good idea (i'm getting some of the afb 1212's in). i think the 38mm is a bit overkill, try those delta afb 1212's. uses less power n quieter, imo it should be sufficient. on the wooden rig, i think the gpus are sitting a little too low. some models of gpus does spits air out to the bottom but with the fans there it should help. a little more breather space like the pic below. yeah most likely it's not as bad as an open case compared to a server case.



tested before by placing a fan in front of the intake, lots of ample space & it cools down the board too, not too bad 2 in 1. might implement that on future revisions.

i haven't actually power the 1500's up yet. basically it's the same size (width) of the 1200's but it's a tad longer with dual fans on top of each other. wait let me snap a pic a measuring tape next to it, but i think it should fit into a 4U case.



do take measurements of the bboard that you are currently using & some space for cabling but most likely it should fit in nicely.

your server case, what is the direction of the flow, if i'm not mistaken it's front to back so there could be some hot air passing thru the intake. just test it out & see how it goes with various positions.

ah ha, i have a cooling solution for you on the bb's mate. based on your pic above, can you place the bb at the same spot of the HP ? if you can then move it a little to the right so you can fit a fan between the side of bb & the wall of the case, draw some lines, either start cutting or drilling some holes, i;d personally go with drilling some holes. voila, air intake or exhaust solved for time being.

speaking of pico, i've been getting some PM's, please be patient as i ran out of stock & will be only placing orders this coming monday & it does takes a while for them to reach me excluding mods. here's a pic of them. top is standard 18 awg wiring with a modded pcie header. length of the cable is roughly 30cm. bottom is modded with a 16awg cable with pcie header, length is approx. 52cm.



let's see if the OP warehousing offer still stands. i can get more accurate shipping rates to USA now. let's see how it goes as there's few more steps to go before i can get my hands on them. prolly finsky will be ahead of me in modding them & have them delivered. OP, can you snap a pic back of the pico that you are playing with ? do take note, they do get a little warm, make sure there are some airflow over them.

*** i'm NOT doing any ads or whatsoever, it's just a community request & i'm trying to help to supply them & i do not make a fortune out of them ***

I have a bunch of these, now not used, because of rigs moving from Windoze to Linux.

There are cheap ones too, not the Compulab ones (which is Made in Israel) but very hard to get or no stock.

Suggest that if you get the cheaper ones, try out one or two before buying in bulk.

@ All - Favor to ask to keep the thread easier to follow and less repetitive.  Let's use @ person for the response when possible rather than quote the entire post for the ones with pictures to keep it less bulky / more scrolling.  It will be more important as this thread gets past 40-50 pages where I need to do more streamlining.  


**************Design Lab brewing *************************

First I want to thank all the people who are supporting me on this project

1) Wife and daughter - Wife did all the Network cabling and prep all the GPUs.  My daughter is spray painting the RIG frames
2) Hawkfish007 for supplying H81 MBs as my Racing MB are so problematic.  Most importantly his AWESOME PCI RISERs!!!  
3) Finksy for sending me more 4KW server PSU, Fans, cabling and PICOs for the prototypes.
4) Cryptowatcher for volunteering his time to make me custom cablings
5) MarkAZ for heating and cooling recommendations / ideas.  This guy is a Genius.


 I'm not sure about you guys but I get tire of the same old boring designs that haven't really improved for GPU mining over the past 5 yrs.  This is why I want to continue pushing the envelope and see what other cool new designs we can come up with.  

Lots of stuff!  Designing with Wood is fun and easy.  Hopefully 1 day I can find cheaper metal material and make custom cases.  

Lots of HP PSU, Finksys Hurricane Fans and tons of Hawkfish007 risers!







I had a AHA Moment when I saw the HP PSU's compact design and said it would be perfect for the SERVER CASE!!  But upon testing it, this HP 1200W PSU gets Stupidly high Pitched LOUUUUD  due to it's tiny high RPM fan even when barely pushed over 50%.  The only way to keep it quiet is to feed it cool air or have another FAN to blow at it.  I don't know how I'm going to be able to do this with the server case design so back to the LAB to tinker on this.






Finksy's Custom PICO designed by a Miner for Miners!  
It came out way better than expected so I can't wait to get my hands on them.  





Heavy investment
This is a very big investment for me just to learn how different GPU type, size, air flow work best in what config etc.  In a large farm, it is more practical to standardize on only a few types of GPUs.  This standardization help keep operating cost low (same ROM, quickly understand issues, etc) and also make it very easy to RMA similar GPU type or always have a GPU receipt that is within 30 days for quick returns of fail ones.  So needless to say after all the design work is done, I will be selling these to friends for very cheap prices as I prefer this type of standardization.  

This is also over 4 rigs worth that are just idle for different configs and the only time they will be mining is during the heat and power tests.  Expensive project as that's an opportunity lost of almost $1K a month at current income level.  However, I think it will be worth it as we may learn more things from this rather than keep doing the SAME OLD SAME OLD.  Please keep in mind, I got mostly RX470s but will also use different GPUs to test as we have a future proof solution not just an EASY Solution (470).  


This is only half of the gears shown.  The other half is in the garage or in transit.





Here you can see I purchased most of the different RX470 that matters.  I didn't bother with the Sapphire Ref 470 as it will operate similar to the 480 in the picture.  The XFX single fan is actually very tiny, this picture, somehow is not showing proper proportion but it's very tiny compare to the MSI red.





The only way I can SHUT UP the HP 1200W is to give it a beefy Hawkfish007 or FINKSY fan.  I can't recommend these HP1200W for home use or even the garage unless you can use some other fans to keep it cool.  The high pitch noise will travel thru my Garage door vs the white noise from the bigger fans that wont.   Not as loud at Antminer S7 / S9 but almost just as annoying!  You MUST feed it cool air to keep it quiet.  I will try to make a custom Fan mount for it but I wonder what will happen during summer high temps.  Even if your office is 70F AC, it will get hot and get stupid pitch loud.  For open air, should be easy to solve this issue with box fans or a custom fan next to it. However I really wanted this to work for the Server case as the form factor is perfect!


@YSYLUNG - Does the HP 1500W have bigger fans and is maybe quieter?  I need a server PSU solution for the server case and the IBM 2KW wont' fit sideways nor is there a good fan solution in that space to keep either the HP1200W or the IBM 2KW PSU cool.



Thank you everyone for following and for your valuable feedback and support.

Hmm has anyone tried el-cheapo HDMI to VGA adapters that are like under $3?

I use an emulator like this https://www.amazon.com/CompuLab-fit-Headless-Display-Emulator/dp/B00FLZXGJ6/ref=sr_1_1?s=pc&ie=UTF8&qid=1489268350&sr=1-1&keywords=emulator .
