Ok, still looking for answer if Corsair VS650 would be good to power 1 S3? I am not good with that stuff, so I will not be modifying server PSUs.

According to the table http://www.corsair.com/~/media/Corsair/download-files/manuals/DC_Cable_consolidation_Rev_28.pdf the VS650 has only one PCIe cable, and therefore is not suitable to run an S3. You need two PCIe cables, four if you plan to overclock (plus higher wattage).

EDIT:- above assumes you don't want to use 4-pin molex to PCIe converters.

Hmm I dont know then any other PSU good for powering 1 miner, can someone help me?

here are photos of 1 cable into 2 pcie plugs this will over heat--------------- notice I leave one plug empty. I use the second plug for a gridseed blade

I can point out quite a few good psu's for you. just let me know the country you live in.

(if you are in the usa I have 4 or 5 good ones I could send one to you)

For 1 S3 you should be fine. Even over clocking it it shouldn't pull more than 450 watts, which is about only 75% efficiency. Most PSU's can handle 75-80% efficiency without issue, and Corsair has good products in general.

Ok good, what about the cables? Is it ok if 2x 6pin connectors are on the same cable?

Probably not related to the topic 100%, but I'm using Corsair RM850 for 2 overclocked S1's without any problems, stable, and pretty efficient

I'm thinking of getting the Cooler Master V1200 Platinum PSU (http://www.coolermaster.com/powersupply/v-series/v1200/) to power 3 S3s would that run fine? Everything is going to be on stock, no tweaks whatsoever. I just need something that can power them reliably.

Also, a pretty noob question... The datacenter I am looking at provides 6 x power sockets of 13Amp over 220V each in the cabinet. Does this mean that in total I can put equipment that consumes approximately 12000~ watts of power usage without tripping anything? Or should that be ~2000W?

Cheers

maybe maybe not.

if you drop to freq 212.5 most likely yes.

I have some evga 1300 watt golds. they run 3 s-1's at freq 393 overclock pulled 1215 watts for 1 month in a row. I would think they will do the trick.

I'm running two S3's of a FSP Aurum PRO Series 1000W Modular PSU, which gets a generally good review by Jonny Guru (http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=292 is the hot performance stats)

I've also got another two S3's, each running off a FSP Raider 650W, with an adapter cable to use the EATX 8-pin CPU power lead as well as the PCIe 6-pin power lead.

Use a good rated PSU, for example corsair, for two units, i am using HX1000W corsair psu, no problems at all.

By far the cheapest option is the old good Dell server PSU N750P series. Modifications to run as stand alone 12V power supply are extremely well documented on the net, it's available everywhere for less than 20 Euros or 15 GBP. Very high and stable output, designed to work 24/7, slim and less bulky than ATX, very low losses (around 7-9W), runs cold and quiet. All you need is two 6 pin cables of modular type, cut one end of each cable, one short insulated wire to bridge pins A1 and B6 on PSU to trigger auto power on, one jumper across A1 and B1, one jumper across B2 and C2 (to stop the fan from spinning full blast in emergency mode). And it just so happens that the +12 and ground output blades perfectly match with 6.3mm female crimp connectors, so adapting 6pin cables couldn't be any easier. I then use short piece of heat shrink tubing around each blade connector to provide snug insulation. 20 minutes of work tops, less than 30 quid in parts.

Ok ok good, so Corsair VS650 should be good, as I have read it has 2x PCIe 6pin connectors, right?

not sure they must be on 2 cables. not 2 plugs on 1 cable

2 per PCI-E for non-overclocked just like the S1.

We use the Dell Z750 server PSU to power 2 OC'd S1's and they run just fine. You'd be good with those and they're pretty cheap. Look into the "breakout boards" for them, you can get a PSU, board and cables for under $100usd which will power 2 S3's

I am planning to run 1 with 1 PSU, so no problem

Do I need 2x 4pin or 6pin connectors to power it without overclocking?

Ok you guys are right. So what about corsair vs650? I have read under specs that it has 2x PCIE 6pin connectors, but those probably wont fit the S3?

Keep in mind that you can only order the S3 in batches of 2 from bitmain, so if you want to run two S3's, you need a PS with 4 PCI-E connectors and higher wattage.

Ok I understand. I found some really cheap PSUs ( Tecnoware ) 500W PSU for 25€....what you guys say about that? If they are ok to use, I would use 1 on each miner.

As I wrote, a really cheap 550W PSU in my case was just a waste of time and electricity and single unit ended needing two of them. If you don't want soldering/modding server power supplies you need to invest in proper single rail PSU that either has constant wattage (24/7) figure in specs or is rated at twice the power you need (750W for single S3)

Fully agreed. At the end of the day, you want to have peace of mind that your mining operation is running stably. That way your time can be spent on better things, ie setting up more miners Wink
