A PicoPSU question (from a newbie miner so be gentle) -  I've seen advice given to power your risers off the same PSU as your mainboard to avoid troubles, but with a Pico there is neither the connectivity or capacity--thoughts?

- m0b


in the example below   where is all power coming from?

 the big ass psu

 the pico  acts as  as an inbetween  but it draws juice from the big ass psu



big ass psu ------- pico psu  -------- 24 pin to mobo
big ass psu ------- pico psu  ---------   8 pin to mobo/cpu
big ass psu ------- riser 1
big ass psu ------- riser  2
big ass psu -------- riser 3
big ass psu -------- riser 4
big ass psu --------- riser 5
big ass psu ---------- riser 6

Ahh, ding ding. I missed that part. I assumed it was fed with an external 12V PSU like a laptop charger.  Thanks!

Completely out of Motherboards everywhere.  The FRENZY IS BAD!!!!!!!!!

I have 14 x unopened H81s .... I can sell it to you if you want...... NOTTTTTT!

LOL.... just joking yun9999... sorry for busting your chops in these stressful times  Grin

I am also in progress setting up my 2nd farm so I am also short on mobos.

I get most of my stuff now from the resourceful yslyung - you should ping him.

I have not been following graphics cards prices too much recently, but found 2 on craigslist, would this be a good deal?

Gigabyte GeForce GTX 1080 Founders Edition - $425

and

MSI Radeon R9 380 4g - $220

and

Radeon R9 380 4GB DDR5 OC Edition - $125

Would any of you pick these up?

Thanks

You can do better than that...I've seen Newegg on Ebay selling brand new non-reference 1080's for $419, and 1070's for $319


just checked newegg


this is pretty good price

the 1080 is good if it works.

it will do 510 zec at 170 watts  counting  your entire system at the wall on a k-watt meter.

that card runs around 500-550 new.

I now have a 3 card nvidia rig for zec   about 580 watts  for 1830 h :

 two 1080 ti's and one 1080

Pleased with it.

https://bitcointalksearch.org/topic/m.18500068

I suggest that anyone with  3 six card amd rigs   should have 1 three card nvida rig.   Use 1080 ti and 1080 for density as  three cards giving 1800 plus zec is very nice

The 1080 for a mean ZEC rig would be my best bet.

The R9 380s are good in their hey days.... but the older R9s are power hoggers, so I would stay away from them... might as well consider a brand new RX480/470 for about 220-200 price range.

@ phillipma1957 - Until there is better Mining software for NVIDIA, AMD is still KING for the coins we care about for now which is ETH and ZEC.  More importantly if you're dual mining.  Also NVIDIA is very flakey in 6 and 7 GPU setups due to driver and mining software compatibilities.  This is why I'm still 100% AMD. 

ZEC is good with NVIDIA; can't say for the rest of coins though ~ ETH is poor for example.

Eg. EWBF and Excavator miners drives high ZEC hash (even higher than ZEC on Fury X at very low watts).

Many good cgminer forks for other familiar and unfamiliar algos like DCR, LBRY, Lyra2, X11Gost etc.

Pros: ZEC killer (and only ZEC though, I wonder what clicks in ZEC and NVIDIA architecture), impressive wattage - better than AMD

Cons: Bloody expensive...

Started building my first ZEC rig on twin 1080ti, hopefully this will be an equivalent of a 7-8 rig AMD ZEC rig, at half the watts. Patiently waiting for Phil's weekend review.

2 cards now  one  1080 ti one 1080


watts for entire rig = 373
h for zec                = 1168


pretty much  kills anything from amd in the world of zec

my advice is build 3 six card amds
for every 1 two card 1080ti

two card results
https://bitcointalksearch.org/topic/m.18496734

why not get two 1070s with low power limit they will do around 930 zec for around 300 watts the 1080ti should be doing like 1k for it to be worth it

Part of my model for mining is sale of gear  that is near ROI. 

So the 1080 ti zotac  will be sold  to a friend that has a gamer wife.  I will sell it to him in about 120 days.

if it does 670h it will earn around 5 bucks a day  - 1 for power = 4 x 120 = 480 I spent 704  so  I would be 224.  If I sell it to him for 375 it is a good deal for him  and I profit 150  .

I do this with many of my cards.  He has a 970 in his  wifes pc system  she will love the upgrade to the 1080 ti.

I have a nvidea mining Rig, it consists of 1070, 1060, 980, 2 x 970. Only the 1070 is new, rest all i picked second hand. This rig runs on windows / nicehash and mines bw Zec, Lyra and Pascal. Its very stable, much cooler and I am sure I can sell the cards very easily when ever I want to. So if not for ETH, its Nvidea for me too !

Also nvidea supports much more algos(nicehash) than AMD, so I think its going to be much more future proof then AMD.

You are a smart guy. I 'm really interesting with your mini mining garage. I will try to get a mini room like yours .
Good luck , guy.

@Yun9999 I was shocked it happened as well. I've trusted EVGA products for years, and knowing that the 1200W plat is literally the best possible, having it die on me on very first power on was pretty shocking. Could it be that I had it plugged into a surge protector with a monitor and box fan as well? I really don't think so since I did hear the pop in the PSU and the smell, plus the fan/monitor stayed on and constant, just trying to figure out how it would have passed EVGA's inspections on their devices and still pop instantly on me. And thanks for the heads up on the 1 fan variants, I'm running just an open air build on a homemade wooden setup, so I'm guessing it'll be fine. Ambient temps are always around 70, maybe 80 highest in the summer.

You can consider some RCDs, basically the EU version of GFCIs. They are less sensitive since they are designed to protect whole buildings or large portions of one rather than individual circuits.

@Navydude - If you have a larger structure, it will most likely be more secure and protected against moisture or potential for leaks, etc.  For small shed, it's impossible to build something that strong where it can survive strong storms, etc.  So GFI is a must in those situation vs potentially doing away without GFI.  Using GFI is not good for mining or PDU as the more devices you have on the strip, the higher chance something will trip or cause it to not able to reset.  Not using GFI when doing 240V is asking for a death sentence as moisture and wet area could be very dangerous if you have a power leakage somewhere.  240V will kill you unlike the 120V shock that you may be able to survive if you have room to get away.  Going 120V is another option but that would waste double the amperage.

Regarding fan CFM - IT really depends on your shed size.  REmember higher CFM = more noise usually.  However you can get multiple smaller fans and combine they can move similar CFM and not be too noisy.  This is why I'm using my ORIONs.

@miner147 - Single Fan GPUs are fine for 470 as they don't run as hotas 480s anyways.  For 480s it will get warmer or louder via faster RPM as the single fan have to work harder but for 470, they run super cool.  Regarding the PSU capacitor blowing up.  Usually it doesn't hurt other GPUs or MB but sometime it does.  I have 2 go out on me.  The good thing with EVGA or AMAZON is the return / RMA is super fast.  Very surprise to hear on the Platinum 1200 which uses Japanese Capacitors.

@ dddrgonzooo - Correct, just more ways to be tripped happy.  I run only 2 or 3 rigs per PDU in the shed now, talk about huge waste!
