PSU for Antminer S3

[videoeppo]

I guess most of you have upgraded to S5 or S7, but this is my experience with the psu units for S3 i had bought. I got it 4 S3's from a ebay. Since i was a complete noobe to this I got got the recommended psu by the seller which was cooler master thunder 450. It was a 450 watts smps. S3 consumes about 380 watts for both its walls. but the point here is the smps has only 80% efficiency. May be i get only 360 watts out from the smps. Also the wires were to be modified. There was is only one 6 pin Pci-e. the other one was customized.

After running the units for 4 days (with one hour break), I found most of the wires burnt out.

I bought wires and pins and learnt to crimp from the net. I made my cables but it wouldn't last more than a couple of days.
I realized the issue was not in the cables but in the Smps which was not able to take the load.

I did a bit of search and found that Antec VP650PM has two 6 pin Pcie outs.( Its VP650PM and not VP650P). I bought this unit. but to my dismay the connections on this 6 pin PCI-e where different. Therefore regular modular cable which i had wound not work.
Only the cable supplied with unit worked. Since i had bought two units I used the cable from the other unit to power up a single S3.
VOila!!! no heating issues. The cable are rock solid.(touchwood!)

Then i used two leftover 450 watts smps, just connected the 6 pin pci( leaving out the modded cable) and powered one more S3.
This worked too. Cable are warm but not hot enough to burn.

I need to order for antec VP650pm cables which are available with moddiy.com
Before that, if anyone has spare cable let me know. Any better solution let me know

I am not a professional so I do not know much about this stuff. I do my research on the net and learn from the forums. This i what i learnt and wanted to share.

Use all four PCEI plugs on the S3 even thu they say you don't have to, use one single PCEI plug per plug don't share two plugs with one if you can help it.

That PSU is one of the low ends ones from what I found  searching . try to buy a PSU with one rail or I all ways have .

I would use a 650 or higher for safety reason and make sure or try to get PSU's you USE for mining @GOLD or better standard. even a 550 gold standard  will work with lots of room for spikes etc.

sorry, i can't really link any good 550 or lower, can't say i trust any thing that low my  PSU atx types are 650 or higher, my server PSU's  are about the same . as for cables be care full , some PSU's  will only work with the cables they came with and can dmg your Miner if you use the wrong cable , im speaking from doing it by mistake or it may not power up fully with the wrong cables. or  have some custom made for that PSU etc .

for any miner get at least 16 weight or better wire so they don't over heat with the matching PSU.

Im running two S3+ overclocked to 243M and they both run off a Corsair RM1000 PSU. Runs with the standard cables (8pin to 2x 6+2 pin). I know its not advised running the split end cables but ive had no problems so far.

here is quick advice warm cables  can do this  and you had 1 meltdown already

[in2tactics]

I have two very similar AntMiner S3 setups. The first setup uses a Corsair RM1000 to run 2x AntMiner S3 and the second setup uses a Corsair RM1000x to run another 2x Antminer S3. I have had no problems with over-heating cables on either Corsair PSU. When mining, the key is to always use a quality PSU. I would also highly recommend using a PSU that has a single 12V rail.

[videoeppo]

May be i should get Corsair RM1000 for the other two miners i have. But wouldn't it be wise to sell the S3 ( 4 of them) and invest in an S5. I have already burnt up cash on cheap psu's which i shouldn't have done
Or will this "CORSAIR SMPS RM 550" suitable for my need. Will the standard 6 pin Pci cable work on this? or will the kit have two pci-e cables?
I am asking this becuase not many details are available

[videoeppo]

this model
http://www.amazon.com/EVGA-SuperNOVA-Crossfire-Warranty-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?
is not available in India. even if i try to import, there will be duty and taxes which will shoot up the price.
Any thing on the same line available here?

all brand new atx psu come with everything you need expect the jumper which you know how to do with a wire if your running a s3 now on the psu you said  and even some of them come with a jumper to test with . but the nor is  brand new never open in a retail box you get everything needed to run it but the jumper and sometimes that's even in the box. even some OEM buys come with just enough to cover all the plugs you need.
 
and kind of another reason you might want to get a 650 or higher you may still need some pcie cables or only be able to plug in a s3 using one pcie or sharing two with one with a 550 none gold. most of the gold standard 650 or higher i have and are modular cabling, have all i need.

and those are in deed nice PSU i have one i use on a grindseed g black miner I got a year or so ago for  90 bucks brand new .I think i paid on ebay with fee shipping.

info here is so useful. Thanks guys. I should have checked before i made my investment. I will check on this product.

On upgrading miners..... we would need to know more about your electricity price.  But yes S3 are getting more and more dated.  But if free electricity.... profits can be made.

On PSU's don't go cheap they are a investment in mining.  A good one can last multiple generations of mining gear, and also be sold at end if you don't need it.  If your stuck with 110/120 and want the EVGA supernova it is a good psu I have a few and like them.  I also like my RM1000's to so just depends on current pricing and your needs.

One thing now to is server PSU's.  They really have gotten more popular.   If you have 220/240 especially you can get a lot for your money going with a good server PSU.

But isn't it recommended to buy APW3-12-1600-B2 for antminer products?

They do recommend that PSU for one Antminer S7.
But after all it doesn't matter what PSU you use as long as it is reliable and has appropriate specifications for powering your miner.

But isn't it recommended to buy APW3-12-1600-B2 for antminer products?

The s-7 is a high power many pcie jack machine.  The APW3-12-1600-B2

Is built special for the s-7.
It is not built special to run 3x s-3s as it uses 18awg cables and only 10 of them

So if you want to run 3x s-3s with 10 cables one machine will have 2 cables not 4
So to be safe you need to under clock it just a bit.

The psu is good for 2 s-5s

What I've used since I started mining for the S1 and S3 are Corsair CX600.  They cost less than 500 and have that extra power so your not pushing them near capacity.  For S5 I've found that with overclocking even my 900w supplies are being pushed to the limit. Get a higher wattage one if you can for those units.

I've just gone through a psu learning experience with my Avalon 6, I was using two 850w gold rated psus on it, but I did not notice that one of them used 18ga. wire and I melted a plug.  Once you get above the S3 level of gear you want to be sure to have 16ga. wire on your pci-e connectors, otherwise they will melt down.  Probably even a good idea to have 16ga. wire for the S3.  Always use a gold rate psu at the minimum, the efficiency increase is noticeable at the wall.  Try not to exceed 80% of the psu rated load.  If you want to get serious, get a server psu, try someone like holybitcoin.com.
