Topic: 13 GPU Rig Power Supplies (Read 1088 times)

Thanks. Yeah I actually talked to EVGA an hour ago & while they don't sell 240 plugs I've got the 5-15 to C13 plugs for a few $ before I was really surprised that EVGA was not only open, but was in the US & very helpful. I ordered 4x 1000 G2s

One last thing though. Last week I ordered 8 of these: http://www.ebay.com/itm/18AWG-PCI-E-Graphics-Card-Modular-Power-Cable8pin-to-Dual-8pin-for-Antec-Series-/282559588497 for my 1st rig. The idea was to not use additional 6/8 pin splitters, basically to split the 4 VGA cables just like the 2 that already came split with the PSU..

I was about to order another 16 of these cables(haven't got the others yet) & saw they said "Compatible for antec module power (NP series, TP series, ECO series), Other Brands and Models PSU not Support !". Do you think that matters? Normally I wouldn't worry except that a few weeks ago I got a few 8 pin extension cables from Fry's that didn't fit, like the pins(square & rounded) didn't match up, so I took them back..

I'd hate to order 16 of these & then they not work. I don't get why some fit & other's don't. I'd simply compare the picture with one of my VGA cables but I'd have to stop mining to unplug one

If I have to I could make my own cables like this: https://www.moddiy.com/products/EVGA-PSU-SuperNOVA-VGA-Modular-Connector-(8%252dPin).html but this is literally the last piece of the puzzle so I'd like to just get this over with( 2 days & $15k later.. I'm tired)

If a PSU can do 100-240 then the amps are directly related to the v. So at 100V the psu will do 13.5A, at 200V it will do 1/2 of 13.5 so 6.75A and at 240V it will do 6A. As far as I know all psu sold in the US will come with only 1 AC plug - that is the standard 110V US plug otherwise known as a NEMA 5-15 with a C13 connector on the psu side. As for plugging them into 240V it depends on what your receptable is at the 240V location. You would then need to get a cable that plugs into that type of outlet with a C13 connector to go into the psu. There are several options for plugs/recepticles over 110V so its just a personal preference more than anything else. I personally like the NEMA 6-15 type - very similar to a 5-15 but its 240V/15A looks like a normal US plug but the two vertical pins are horizontal - so if by chance someone happens to see your 6-15 plug and want to plug a 5-15 into it then it wont fit and they wont fry whatever device they wanted to plug into it. Also generally speaking all psu's are more efficient at a higher voltage.

I really like the idea of a PSU that can run 110 or 240. Only thing is while most EVGA PSUs show 100-240v input, not all show the 240v amperage. The 1000wG1 does: https://www.evga.com/products/product.aspx?pn=120-G1-1000-VR stating "100 - 240 VAC, 13.5-6A" which would be perfect as I could get it going on 110 here in my house, work out any issues, then take it to it's final location(out of state) & connect it to 240v.

Again, most if not all EVGA PSUs show 100-240v but don't all list 240 amp draw. Any reason for this? & let's say I do end up buying a few 1000wG1s. Does it come with both AC plugs? Or do I need to choose one etc?

Any help is greatly appreciated & to be honest if someone with a decent amount of experience PM'd me & helped me get a few details ironed out I'd have no problem sending some eth or btc your way

Any idea how many amps this PSU uses? It's not listed & the image isn't large enough to see on the label.

Pretty good suggestion, thanks! Only thing is I don't have 220v here where I'll be building/testing them & just like before with my Antminer(had a 220v PSU for that) it turned out to be cheaper to just pay more for a 110v PSU(or a few) than to get a permit, pay an electrician & in my case, completely rebuild the breaker box to get enough 220 lines.

220v PSUs are a lot cheaper & more efficient(I hear). I'll look into it but upfront 2 of the 220 PSUs & 24pin adapters save me about $250. The electrician fees to get 220v are gonna be at least $600-800 or more. BUT if somehow the 220v being more efficient in the long run saves me $ I'll do it, just right now I'm not 100% on the real differences.

That being said on the 110v PSU front while technically 2x 1000watts would work, I'm concerned that the 1st PSU running 7x 1070s + the MOBO & SSD would be right there at 980watts & that's after I under volt the GPUs, so wouldn't I have to start a few cards up, under volt them then get a few more going so I don't try to pull say 1100watts from a 1000watt PSU? I did accidentally once pull like 1525watts from my 1300G2 once & it was fine(can't imagine it was good for it).

If not for that I'd order some 1000G2s right now, but I'm thinking maybe a 1300 to run the mobo, ssd & bottom 7 cards/risers & a 1000 to run the 6 top cards/risers.

Just get one of these:

Then simply enjoy the increased reliability and efficiency of your rig.

I'm using all Gigabyte 170 G1s & was able to get 18 yesterday(sorry gamers) needd 8 more I would much rather use 2x 1000watts & save some $

Better is 2x 1000W Corsair PSU, i think is better than server psu

It is better to use two 1000W PSU. It will sue about 85% of the rated power and with higher efficiency.

+1 Server PSU are way better designed for this... something like this : http://www.parallelminer.com/product/gpu-mining-power-supply-kit-hp-1200-watt-80-gold/#reviews

2 1000w power supplies can be good, just be careful because at 1700 you are going to be pushing it really hard.

You can also try having triple psu rig, msybe 850w*3, its not as space efficient as 2 but it could work

Whats GPUs are you running?

You could go for a 2000w server PSU. Server PSUs are better than your consumer evga or corsair PSU because they really are designed to run heavy loads 24/7. Also more importantly, server PSUs are cheaper (in terms of SRP) and are always either 80+ Platinum or Titanium certified. Only downside is you have a harder time selling it once the mining fever dies out.

If you're recording 1700W at the wall, a 1000W+750W or 2x 850W configuration would not be sufficient. For 24/7 operation especially, you want to avoid pushing your power supplies close to the rating.

Additionally, balancing the load between two PSUs when you only have 50W or 0 for leeway wouldn't give you many configuration options. Chances are, you'd have to put one slightly over the rating, while the other one was left slightly below.

I would consider 2x 1200W PSUs (obviously from a reputable brand & OEM).

I would suggest two Corsair RMx1000 or EVGA GQ 1000w. Though personally It's better to have higher wattage for efficiency. I run EVGA 1300w and Corsair 1000w or 850w depending on the rig.  I'm personally looking into specific mining PSUs, you can find them on ebay that are 2000w and power the whole rig.

I'm building 2 new 13x GPU rigs. I already have 1 rig like this that I'm using 2x EVGA 1300 G2s but actual wattage is a little under 1700watts. Obviously a 1000 watt & a 750 would work, or 2x 850s but not be as efficient.
So I'm wondering what would be the best combination of 110v PSUs if not 2x 1300 (sold out & higher price now)

Thanks for any suggestions:)
