A cheap Ikea (or similar ) cabinet useful to be filled by antminer s1? ( it could be much better if it is no opened in all its sides for a silent solution )
Thanks

No problem, pedro.
Yes, this is a very important aspect. You want to avoid group regulated PSUs at all cost. You need independent DC/DC regulation for machines which draw mostly/only 12v power.
I think at this point only sub $50 junk PSUs will feature undesirable group regulation.
I wouldn't buy them at full price, but I'm running two S1s on a HEC 850-TS, which is the same PSU as this Cougar one.

Unlike most cheaper supplies, it uses DC/DC for the minor rails so it's perfectly happy to sit there with no load other than 12V. I think I paid $124 after a $90 MIR for three of them.

Hi guys,
could you tell me a cheap and good psu for antminer S1 (with oc) ?
Thanks

Good and cheap don't usually go together, but if on a budget this is what I would trust:

Any of those would be fine. Seasonic is always the way to go for quality PSUs, you simply can not purchase a bad unit if it has Seasonic's name on it.

380w / 180GH = 2.1111w x 205GH = 432.7w x 2 = 865w
thats my take on running two OC ants from a 860w PSU anyway
thats my take on running two OC ants from a 860w PSU anyway
Remember that 865w at the wall does not mean the power supply is outputting 865w of DC power. There is an AC to DC conversion loss.
865w x 0.88 (general efficiency on a Platinum PSU running full load) = 761.2w of actual load on the power supply.

What would be the hash rate of an antminer if you OC ?
2 ants @ 400MHz OC
only with "#" oc mode ? Have you changed other settings of freq file ?
Yes, only removed/added # to select frequency. Nothing else.

Hm, very strange. Which model PSU? Corsair AX860 or AX860i? Only thing I could see is that maybe the PCI-e connectors had loose connections (even if well clipped) which increased the resistance and heat per pin.
Each connection had its own pci connection. With a load of about 175w per cable.
In all fairness the psu in question was heavily used. I had three 860w fail in the same week, all were RMA and replaced.

It was an 860w platinum not the 860I
2 failed and melted while running 2 x antminer (720 -750 load). the other did the same but with only 3 x KNC boards pulling less than 600w
as i said the PSU were heavily used, but still the one with the 600w load was worrying and i had noticed the cable connections were running pretty hot before it happened.
Either way all PSU were replaced by Corsair.
Can't go wrong with Corsair when it comes to customer support! Glad they took good care of you.
I don't understand why this happened to you though.
When you say heavily used, do you mean the PCI-e connectors were in bad shape? each PSU had also been used to run a 82GH(700w?) gen 1 avalon and about 650w load form KnC jupiters and then Ants, the 700w loads were probably pushing it.... that includes the Ants

Can some of you please monitor your watt usage more closely?
My ant oc'd to 400mhz will pull 420-450watts, but I've seen it spike to 550+watts. It's sitting in the 490's right now.
If everyone else's does this, the PSU's some people are using might be too small for these spikes.

I was actually watching my power meter yesterday and noticed several large spike after i turned the remaining antminer back on.
Sold today and only running KnC boards now, at 160GH for 175W it makes in more ideal for me when paying 0.25 euro cent per KW that running 350 - 380w to get 180GH.
Due to limitations on power at home it is much easier and manageable for me to run over 2TH with the KnC power spec than with Ants

Nice looking setup, here is a question that has been bothering me for a while, Why pay £239 for a 1350W Psu when you can buy a budget 600w PSU for under £20 Delivered ?
I run all my ants blades with there own PSU. I take it I must be mad or something, fair enough it takes a bit of room but will it not be cheaper as the PSU will only be pulling what it needs ?
I have 5 ants in total so that's 10 600w PSU's.
Going to get a multi meter to measure what it is pulling all my miners are running between 205 and 210 Gh/s
Cheers
You don't want to skimp on the PSUs! Cheap PSUs will have very poor voltage regulation and ripple suppression, and will not be able to put out the power they say they can without either blowing and taking everything connected out, or if you're lucky just powering down.
Please spend 30 minutes reading the following for your own safety (potential fir hazards) and for your equipments health.

so you have 10 600w PSU's
so that lot will be pulling 6000w Max
i have 1 1500w running 4 Ant miners
hmmm i would who is going to win in the long run lol

That is not how switching power supplies function. Devices will only draw what they need. Using a 600w power supply with a 100w device does not mean you're pulling 600w at the wall. You'd be pulling around 125w at the wall with this example.
Well, I have been running my first antminer since november/dec and not 1 power outage and still going strong. The brand is Antec with 30A on the rail so my math dose me right that is pretty good if they are only pulling 125w each. I will know exact figure tonight when the multi gets installed.
Fair enough firehazard it's in a cooled environment max temp 8c cable from the extension is warm and has thermal cutout built in so the cables don't melt. I am going to run a second extension from power source 2 as currently everything comes from the 1 plug industrial wire and plug in use. With also laptop server connected and 1x network switch.
Thanks for the links will give them a read over
Edit: Each of my PSU have Dual PCIE 6pin and 1x 8Pin I have connected a few also with the 8 pin to help spread the load.

Eh what? I have a single Corsair CX 600 Watt ( ~58/ea ) per AntMiner and overclocked (Edit: @400) they pull ~420 Watts via KillAWatt. Why would you need 2x 600w per AntMiner?
They probably only have 1 pci-e cable with 2 connectors
If that's the case, he should cut the end off of the 8 pin CPU connector (4x 12v and 4x ground) and wire them directly to the second blade. Not sure if the CX600 is single or multi rail, but multi rail PSUs will generally have PCI-e on one rail and CPU 8 pin on another rail which would be ideal.
