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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

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.
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.

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.

I originally deviated from my corsair cx500's that I used for the S1 and bought some sentry 750w due to the "4 pcie" but those POS won't even power one s3 when hashing starts (it powers off). They would only power half the s3. I am now powering my s3's with some cx500's. My s1's have been running on the same supplies for months... Four are using cx430 which were slightly modified...

Your memory is failing you, then ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) PCI-e connectors are 6 pin or 6+2 pin. The S1 requires 2 6-pin PCI-e connectors. 1 per blade. The S3 at stock speeds requires the same - 2 6-pin PCI-e connectors. 1 per blade. If you are lucky enough to get your S3s with "good" DC/DC converters, you *might* be able to stably over clock them. If you do over clock, Bitmain states you need 4 6-pin PCI-e connectors per unit (2 connectors per blade). As for a PSU, if you're going to power only a single S3 and not over clock it, just look for one that is at least 500W and has 2 separate PCI-e cables. I recommend the EVGA 1300 G2. It has 6 PCI-e cables with a total of 8 PCI-e connectors (2 of the cables are doubles). You can easily power 3 S3s at stock clocks with it. If you under clock and under volt your S3 (not sure if the pencil mod trick works on these like it did the S1) and can get them to around 275 - 300W each, then that same PSU will drive 4 units.

Then I will need just 1 more PSU to power 1 S3 on its own..

Yes, the EVGA 1300 G2 will run 3 S3s with no problems whatsoever. At stock clocks, they each draw 340W from the wall, so 1020W total, which is well within the range of the EVGA.

No. You have either seen 4-pin Molex connectors, or 4 pin ATX 12v connector. They are not interchangeable because the shapes of the little pins are different. Pictures here http://www.buildcomputers.net/power-supply-connectors.html

Yep. Without overclocking (since this PSU has only 2 PCI-E 6+2 pin connectors). But if you obtain two molex-to-PCI-E(6 or 6+2 pins) adaptor, you'll be able to overclock your S3 too. But do not expect too much overclocking, 'cause this PCU can provide maximum 456W power at 12V line.

I have a VS650 powering an S1. For a month it powered an overclocked S1 (~400W) through 1 cable with 2 PCI-E connectors. The PCI-E wires were running rather hot, barely tolerable to touch. After a month I added additional wires with a couple of 2-molex-to-PCI-E connectors, it dropped the wire temp, and the PSU has been working fine for about five months since. So, VS650 should be fine for a single stock clock S3 (~350W). And adding a couple of 2-molex-to-PCI-E connectors would allow for overclocking and/or give you additional safety margin.

Ok, is there any other good PSU to power 1 S3? I believe there are several good PSUs, for example Zalman ZM600-GLX, SeaSonicSS-660XP2 (even better because of 4 PCI-E 6+2 connectors), Chieftec APS-650CB... You can give me a link to your preferable shops and I will help you to choose right PSU. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Corsair VS650 is not good then as it has 2 8PINs on 1 cable? Well, IMHO not the best solution, but why not? At least if you plan to power only one S3 with this PSU and if there is no other PSU available... See the mutex's message above. ) Thanks Rabinovitch, - you are welcome! i understand. What is the best and the cheapest choice for the S3 ? Which PSU should i buy ?
Please provide me with link to your lovely shop where you suggest to buy it. ) Common recomendations can be as follows: 1) One 12V bus (if possible); 2) 2 PCI-E 6(+2) pins power connectors (4 if possible - we NEED to overclock such kind of hardware...); 3) 450 W and above (I don't know exactly power consumption of overclocked S3; PSU power should not be more than 600-650 Wt for only one S3); 4) 80 plus certificate (higher is better...). Always strive to connect power cables to all 4 S3's connectors. Hey guys...Please, hook up all your 4 PCI-E connectors... ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) You never know what the PCB designer had in mind...but there is a REASON for these 4 connectors...like traces current(s), parallel (redundant) supply...etc...
