Topic: Single EVGA 1000GQ PSU (1000 GQ) for use on a 15A/120V Bitmain S9? - page 2. (Read 2842 times)

 Which is why I specified the LOW hash S9 batches for an X1250 or 1300 G2. They're WAY too marginal for the high-hash batches.



 IMO trying to run an S9 in a DORM is a bad idea - going to be pushing the circuits way too hard and way too loud.

Hi guys,

Thanks for the replies - been very helpful!

I should add that I'm in a dorm right now and would rather underclock to be safe. Cost isn't really a factor for PSU's, as long as they will do. I've contemplated the EVGA-1600s but fear they might break the circuits in my dorm.

Here's my setup:

2x separate 15A/120V circuits (front/main)
2x 15A/120V on a SINGLE circuit

I've messed with some S7's and have been able to run them continuously underclocked at 550Mhz/475/450/400 respectively yielding 4.7Th/s, 3.3, 3.0, 2.7. I plan on building a duct to expel any hot air out the window as this is overwhelming at the moment.

So a few people recommended the EVGA-1300's, which is fine. However, how do I get the 10x PCIe's needed to plug in all 10? There are only 6 VGA's (realized later this was the same problem with the EVGA-1000).

Right now I'm powering S7's with ANTEC TPQ-1200's (1200W) with 7 PCIe cables; each hash board is receiving only 2 PCIe's. I imagine that wouldn't do for the S9's, or would it?


Connected to Monster HTS-5100 MK-II's and Panamax MX5102's for surge protection.


Edit: I'm willing to get EVGA-1600's IF people can confirm (1) It won't fry, short circuit, or burn the whole building down (or pose any other risk), and (2) That my 120V/15A limitations would be enough. Again, I don't want overkill... but also don't want to screw S9's over.

You would still need a buffer for surges. Like HagssFIN, most people with a 1500W power supply for a S9.

The EVGA 1300 G2 or Seasonic X1250 would be enough to run one of the LOWER HASH (11.x TH) S9s, I wouldn't even think about anything less as you will likely fry the PS or miner, and the setup flat out won't WORK at best.

 Don't even try those on one of the 12TH+ S9 units.

 It's a matter of the MINER needs that much power, not that you can try to run it on less.

 If it wasn't for the CRAZY high pricing, I'd recommend you look at the R4 instead which probably WOULD work on a good 1000 watt PS.



 Other option is to use more than one PS per miner, but that gets complicated on the "feed them power" side.

And even though OP said he did not want something pricey on PSU's.  They tend to hold value decent if a good quality.  So you can use for multiple generations of miner's or sell them off eventually.   It is nice to have some good quality PSU's that have already ROI'ed even though upfront cost is higher. 

I have had some PSU's that have been with me for year's.  They are something I never recommend to go cheap on.  Also on Asic gear server PSU's have kinda taken over.     My ATX's have went into ETH gear at this point.

You can't choose a PSU that is able to provide less wattage than it is needed to run Antminer S9.
For example the S9 12.93Th/s version takes 1275W (12 VDC).

Choose for example 1500W EVGA or Bitmain APW5.

Hi,

So I'm still relatively new to this; I signed up just to ask this question that I can't seem to find a thread for.

Would the EVGA 1000GQ PSU (http://www.evga.com/Products/Product.aspx?pn=210-GQ-1000-V1) have enough PCIe's (10 needed) to power an S9? I know I'd be underpowering but I'm planning to underclock anyways.

So VGA x 6 (6-pin PCIe + 2) = 2 rails
SATA 1, 2, 3, = 3rd rail

Left over with PERIF-1 and 2x CPU-1's - Not sure if these would be enough power (or any) for the main board - or if it'd even work.

I'm intentionally trying to stay under 1000W due to power constraints (although if the EVGA-1300 might work I'd possibly be open to that?) - I know the EVGA 1600 works, but they're a bit pricier and I don't want that much power in the first place.

Trying to stay with one (1) single PSU per S9. I'll have about 3x S9's to power. I only want one PSU per S9, so I don't want to combine 3x of these into 2x S9's...

Open to other suggestions, but trying to keep it low key (1050W or less; modular preferred; eco mode preferred).

Thanks in advance!!
