This thread is a total joke - you have finger pointers, speculators, trolls(negative speculators), and those who actually want to share information.  

When KNC shows the ASIC all that sh*t goes away.

i dont think the psu really matters honestly. dont waste money on anything crazy. just get a decent well priced unit and you will be fine, just wait for KNC to tell us the specs first.
A more efficient PSU should give you a longer tail--but that's also when you're earning the least, so perhaps it won't matter quite as much, much as you suggest here.

These are the best power supplies you can buy, I think. I have them running in multiple computers and they run so efficient the fan barely ever comes on to cool it. Never really maxes out and they aren't over powered for the system at all. Trust me, these are high quality power supplies.

I got a couple lying around, so I'm all good. I'm mining with my 28Mhs GPU while I wait. Just for the sake of it. LOL!

You'll find some good reviews of PSUs here on youtube, other kit too. Reviewed and in builds. IF you're sick of reading it's a more relaxing way to find out these thingsI find  http://www.youtube.com/user/TastyPCTV/videos

They wanted it to be rack mountable for data centers.  Racks are typically 19" wide.

The case is nowhere near 19" wide.  They could have made the case 19" so it actually could be rackmounted and would have had enough space to mount a (user supplied) ATX PSU inside AND put the modules in a line.

I never said they were 19".  You can put something in a rack that is less than 19" with a shelf but you can't put something in a rack that is over 19" wide which the case probably would have been if they put 4 boards next to each other.

They could have made a 3 module 300GH/s unit for 19: racks with the modules nicely side by side in a good push pull cooling setup.

They could have made an infinite number of things that they didn't.  They could have built some 4.5 Gh/s thing that would be available in "two weeks" and called it a fucking Pineapple.  But they didn't, so what's your point?

So during my GPU mining days I bought huge Thermaltake 1475W Gold power supply, and it's been sitting in the corner waiting for a miner to play with. I have a Jupiter and a Saturn on order, which means my total power needs should be around 1000 watts. The PSU has 4 sets of pci-e power connectors, so it could technically run two Jupiters and still have over 200 watts in reserve.

The questions is; should I actually run two miners from the same PSU? My intellectual side says it's fine, because it'll be more efficient at the wall having just the single PSU plugged in. My paranoid side thinks that something might get fried in the PSU and I lose two miners 'stead of one.

Here's the PSU I have:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817153154

I also need to purchase a UPS to protect my miners. I was thinking of something like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16842106116

Would this suffice for two miners? Should I go bigger? I know power here in New Mexico can be very flaky sometimes, but it's relatively cheap at 12c kwh after fees. Still need to protect my investments though.

Someone please correct me if I am wrong, but I believe just the Jupiter alone will need 4 PCI-E connectors. I believer each of the PCB takes one PCI-E connectors, so for both of your orders, you will need 6 PCI-E Connectors. Seems you might be needing to get that extra PSU.

I like this, thanks!  Battery back up is pretty cool. I wander how well that works.  
I bought this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171078
It was ~$50 cheaper when I got it.  I think we're driving up the price.

Edit:  APC makes some really good power protection products.  Problem is there are so many and I have no clue how to shop for one.  I may give them a call to see which one would be best for a Jupiter or two.  Also, no need for a battery back up now that I think of it.  If your power goes out, so does your internet.  With KNC products having internal mining software, how would this work?  Does it keep trying to connect to the internet without intervention?  I'm sure these questions can't be answered right away.  So I'm going to wait on this purchase.  Surge protectors are all we should need for now.

Battery backup! Christ, something else I hadn't thought of. Although, I don't remember ever having a power outage in the few years we've been here, so hopefully I won't ever need battery.

Ok, a clarification on the thermaltake psu. It's got EIGHT 8-pin pci-e power connectors on four cables, which is what I meant by four connectors. Each cable splits into a pair of 6+2 pci-e power connectors. It will definitely power two miners.

Which leads back to my original question: Should I run two miners on one psu? Is it safer to run a separate psu for each unit? I do have a spare 650W corsair psu, which I could use for my Saturn and save the Thermaltake for the Jupiter. This may not be as efficient at the wall, but it could prevent both miners from crashing if a single psu fails. How often does that really happen with a 1475W thermaltake gold psu, though? The geek in me says I should use the single PSU for both units. Not just for efficiency of electricity, it means having less power cords to deal with and less space taken up by external psu's.

that's not right. If your power goes out but both your modem and router are on a UPS as well, why would your internet go out? I am mining with network devices backed by a UPS as well and I do not loose internet during a power outage. At least as long as the UPS can feed the beasts. You will need a beefy server-grade one like a SmartUPS.

Hope this helps,

yes, technically you can. but as you mentioned, it is definitely safer to buy new PSUs for each miner. just because, half day of non-mining because of faulty PSU will cost much then new PSU.) I will buy something from enermax, at least with gold certification but considering platinum now.)

Get whatever you feel safest with. Don't cut corners. Solid PSU's can be re-sold, or re-used at a later date. Killing your unit by cutting corners will only mean you may loose out in the long run.

Also is you are running one PSU for both, and the PSU fails, that's both units out of action till the situation is resolved.

Make my day! Say thanks if you found me helpful Smiley BTC Address --->

I wouldn't run the two on one PSU, good call there.

LEPA G1600-MA is the one you want to buy. It's cheaper than most and it has a peakpower of 1700W.
With 1 Jupiter it will run at around 40% max. power; OC it will still be around 50%. And you can power a second Saturn or another Jupiter depending on the final power consumption and still be very efficient. If it fails - well, I would imagine the local computer store near you will be happy to sell you a new one in a matter of minutes. Wink

80+ power supplies are most efficient at 50% load, if that helps with your decision.

I hate fan noise so the plan is to have the PS fans at low dB.
I have spent too many years on a raised floor surrounded by 9million fans,
and on weekends I hang around on turbo prop aircraft.
What am I doing mining if I hate fan noise??? Who knows?
Some of us are here because we're not all there!

I went with platinum and targeting/guessing at 50% based on KnC recommendations.
I expect the PS's will far outlive the miners so it is not a waste.
I also went with twice as many Saturns instead of Hoopiters.
It is more expensive but more flexible IMneverHO.
I'll have room and power for gen2 modules if they materialize.
Plus they will run cooler. I might adjust the 4 module ductage if it is installed in 2 module units.

As mentioned above, ppl with UPS's surf through 'the beginning' of outages.
Luckily I have spare 1500VA's with new battery, prolly good for 5-10 minutes. lol

Don't forget about air filters!
I use furnace filter material for my PC's.
Huge filter so it can get a bit dirty and still have good airflow.
Clean is cooler Smiley

I'm thinking of making a duct for 20" box fans instead of the case fans.
A 20x20 furnace filter fits nicely on the input side.
My goal is huge air and lower noise with easy to replace inexpensive filters.
This will also remove a few watts from the rigs.
I point one at my PC's when I don't want to run the AC.
I also have my equipment on 2'x4' shelving with acoustic ceiling tiles under and around the equipment.
(tape or paint the edges else they are a major source of lint/dustage)
This helps lower vibration and noise.

My decorating motif is 'industrial', lol

Some people pimp their rigs with lighted fans, etc., not me!
Everything has too many useless LED's nowadays, fuck that noise.



Soon! Smiley
