Title: PSU requirements Post by: adamg83 on December 22, 2014, 08:58:57 AM Hi all
Another question thats been asked over and over by the looks of it, but I can not find a simple yes or no answer. Will a Corsair CX500M power 1xantminer s3? It has 2 PCI-E connectors but on one cable. I have seen replies saying yes, and then just read another that says it will but on two cables, but it only comes with 1. thanks for anyones help :) BTCBTCBTCBTCBTCBTCBTCBTCBTCBTC Title: Re: PSU requirements Post by: zlatanBorec on December 22, 2014, 09:38:02 AM Hi all Another question thats been asked over and over by the looks of it, but I can not find a simple yes or no answer.

Power consumption is about 360 W from the wall for Power supply i know it have 3 +12V DC input... i think this is for users who have low power supply... so you can use 3 power supply 150w each... i do not think it is a problem if you plug just 1 500w PSU.

How about the PCI-E connectors? Does it not matter that they are off one cable? Title: Re: PSU requirements Post by: Lamassu on December 22, 2014, 01:10:56 PM Thanks ;D How about the PCI-E connectors? Does it not matter that they are off one cable? It's best to use two because it will reduce the heat in the cables less chance of a fire hazard. However if you keep the miner and psu cool you should be fine. Title: Re: PSU requirements Post by: SargeR33 on December 23, 2014, 04:12:32 AM I run two S3 miners off an 850 Antec PSU which has 2x 40a rails and 2x2 pci-e cables.
Will your PSU handle it? Absolutely. I ran one S3 miner off a 500w fsp for months without any issue. The cables get warm and by warm I mean barely noticeable. Title: Re: PSU requirements Post by: adamg83 on December 23, 2014, 08:14:25 AM Thanks for your replies.
I've woken up this morning to very cool miners, have logged in and they are all (3 of them) going about 260gh/s? i've turned them off and on to see if this helps. Does anyone know why this is? Title: Re: PSU requirements Post by: adamg83 on December 23, 2014, 08:22:50 AM They are now at full speed again. Any advise would be great. They are new batch 11 straight from Bitmain.
Hopefully this doesnt keep happening Title: Re: PSU requirements Post by: hedgy73 on December 23, 2014, 11:22:50 AM Have a look at Dogies S3 thread you might find your answer there, if not post your problem there and someone might be able to help you: https://bitcointalk.org/index.php?topic=702653 (https://bitcointalk.org/index.php?topic=702653)

To be fair it depends on the gauge of the wire and the amps flowing through it. That is what determines how many cables you will need and not just that but also the environment the miners are in. So I guess your mileage will vary Title: Re: PSU requirements Post by: philipma1957 on December 26, 2014, 01:42:32 PM Thanks ;D How about the PCI-E connectors?

So I guess your mileage will vary Also setting freq a little lower hashes lower but uses less power. I can run 3 s-3's on an evga 1300 g2 psu but not at freq 250 they hash at 500gh each and the load is 1280 watts at freq 237 they hash at 475gh each and the psu can handle the load of about 1210 watts these vary from pc to pc.

You have to connect each branch of a split PCIe cable to a separate board (NOT the same board) Title: Re: PSU requirements Post by: adamg83 on December 27, 2014, 05:58:10 AM Thanks everyone
I have them running and the cables are warm to the touch, but not hot. Title: Re: PSU requirements Post by: Argwai96 on December 27, 2014, 08:38:35 AM Thanks ;D How about the PCI-E connectors?

Title: Re: PSU requirements Post by: sloopy on December 28, 2014, 02:37:28 AM If you (anyone) were going to purchase an ATX power supply today which one would it be? I may end up with a few S3s or SP20s, just depends on a few things, but I want to start scoping PSUs. I have been drooling over at the Corsair website and researching about running 50% - some folks say 80% is better for quality and longevity. Also, I'm not cheap, but I want to be smart about things, do I have to babysit ebay or is there somewhere I can pay an extra 20 and find good used, or what are your thoughts? I like new better because of the warranty with things like ATX PSUs, there is a "known" failure rate, and I do not want to get one of those models. I understand in some situations int he crypto community everything is AS IS, but DOAs are generally covered right? What about for miners? Thank You Title: Re: PSU requirements Post by: philipma1957 on December 28, 2014, 04:00:25 AM If you (anyone) were going to purchase an ATX power supply today which one would it be?

Thank You well evga 1300 g2 provides a psu trick switch with the miner. has a ten year warranty and runs 3 s-3's at freq 231 24/7/365 I would not say it is covered but the fact they give a psu short plug helps you to think they are covered. Somewhere there is a long discussion about this on this site. I own 7 or 8 evga 1300 watt g2 psu's and they all work so far. If one failed I would ask for a replacement. I don't really care if it has fine print since the short plug is a real piece of evidence to me that they allow the psu to run without a mobo. |
