Folks, soon I will possess an S5. I am now looking to buy a PSU.

At some point in the future, it may be anywhere from 2-10 months, I will probably get another miner such as S7 etc.

Couple of questions -
1) Should I get a PSU that will support future miners? Ie. get something like a 1300-1500W PSU?
2) If yes, surely this will be overkill for a single S5 and will end up costing me more in electricity bills?
3) Should I instead get something like a 750W PSU and then later in the year buy another PSU if/when I need one?

Appreciate any thoughts.

Check out http://www.gigampz.com They make a PSU specifically for BTC mining based off and Intel Platinum efficiency sever PSU they have the on sale right now for $113 It is a phenomenal deal you won't find a higher quality more efficient PSU for that price.

Ok, say I ended up getting a CSM750, not the CX750.
It's an improved semi-modular, Gold-rated version of the CX750 - http://www.corsair.com/en/cs-series-modular-cs750m-750-watt-80-plus-gold-certified-psu

I thought it would have 4 separate PCIe cables but there are in fact only 2 cables, with 2 PCIe plugs on both.... Angry

Should I 100% get a refund and buy something else, or will the above be ok?
I'm at the stage now where I just want to get it powered and running.

I can tell you for sure this one has SIX separate PCIe two built in with plugs attacked if you don't mind that and 4 separate PCIe you can plugs four more PCI plugs into. it comes with all the plugs you need.

http://www.amazon.com/gp/product/B0090I9W66?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00

but it cost a ton now i see i have two i got a deal on back 7 month ago for 90 each brand new.

.

wow 399 $ for a new one and 105 $ for used .There are nice I can say that, but 399 $ for a new one .I guess i was just lucky.

No you will want to go trade it in for one with 4 pcie cables. You seem to be sticking with Corsair brand. If you are really wanting that brand I suggest the RM1000. You will have zero issues using it.

When your looking at pci-e cables they most likely will list each plug. So if you sort by ones with 4, you are going to get a lot of PSU's with 4 plugs but being powered by 2 cables.

I returned the PSU and got the GX1050 instead, for the same price. The Cougar has 4 separate cables and the S5 is whizzing away as I type this Grin

It's running at 49 degress on stock, but I'm going to change it and add 2 Corsair SP120's I also bought...Will be interesting to see how much quieter it is, but also how much hotter it will be without stock.

Now I just need to figure out what all those numbers mean on the S5 dashboard!

Edit - I noticed for the past 5 or so minutes it's actually been mining at around 1300 GH/S. Thought it was odd considering it's running stock..

I've had this one as well, and you're correct. It's two cables with two PCIe connections per cable.

Ok, I presume given that it'll be powering a miner 24/7 it would be advised to have dedicated cables for each PCIe connection...

And my seach continues Cheesy

It would likely work, but there are better PSUs out there for what you're doing. Such as the ones in my signature lol Tongue

I would consider one of yours if it wasn't for the fact that you're on the complete opposite side of the world to me Tongue

Ah, yeah that does make a difference.

I'd go with the Cougar if those two are your only options, then.

1. it wont be i would but i also have tons of PSU .
2. it will only use what the miner uses not what its rating at or does
3. if you do get a 750 make sure it is at least a gold standard with 4 stand alone PCIE plugs try not to share a plug you will need four PCIE PLUGS PLUGGED IN to it to run it right .

A few i use, I got deals when i bought them i was there at the right time and place .

I know they cost more then a server PSU but I don't care much for the wiring part and broke out boards, wires can tend to come lose etc . i have one server PSU I use form time to time but I'm more the plug and play type guy.

Tip: check out any ware house deals you see on Amazon they claim there is no warr but i have had a few things replaced by the brand under warr buying that way not because it went up, i tested it to see or wanted to make sure it doesn't etc .

Thinking back, for a while I actually had 3 x CX750's running 6 x Antminer S1's ( 2 x S1's per CX750 ). The S1's were pulling 360w / 30 amps each so 2 x S1's = 720w / 60 amps. Which is more than the S5 which pulls 600w / 50 amps. The 2 pci-e cables split into 4 pci-e connectors, 1 cable with 2 connectors powered each S1. The CX750s peak power is 825 w / 62 amps.

Sorry, my memory isn't what it used to be.....

Also remember that the Corsair CX750 only has 2 x pci-e plugs and the S5 needs 4.

In all honesty you're better off going for a branded psu with minimum 4 pci-e connections or a server supply with the same.

If you're thinking about getting another S5 in the future then the EVGA Supernova 1300 or 1600 look just about perfect for the job as philipma1957 mentioned a few posts back as they both have 8 pci-e connectors.

I've seen other people mention this here that the CX750 only has 2 pci-e plugs, this is wrong. As per Corsair's site it has 4 plugs - http://www.corsair.com/en/cx-series-cx750m-modular-atx-power-supply-750-watt-80-plus-bronze-certified-modular-psu

I also don't like using Dogie's guide. Reason being he gives his rating but doesn't state why for example EVGA Supernova 1300W gets 93.0 rating, while the exact same model in 1100W version gets 78.0 or something similar Huh

.....No explanation and it doesn't make sense. Also, he states the CX750 has 2 connectors, which is probably why people don't realise it has 4.

One last comment, what constitutes a no-name PSU? Corsair/Thermaltake/Cougar/CoolerMaster/EVGA/Gigabyte , is it safe to say these aren't no-names?

I can't tell for sure but the CX750M almost looks like it has 2 pci-e cables with 2 pci-e plugs on each which would be listed as 4. But since if it is really just using 2 cables it's not the same as having 4 different pci-e cables.

I would try to find someone on here who has that model to see if it's really 2 cords or 4 cords.

I've had this one as well, and you're correct. It's two cables with two PCIe connections per cable.

Yes that's correct sorry its been a while since I owned one, they do indeed have 2 cables with 2 plugs on each.

Don't even attempt molex to pci-e. On wattage like this it's not if there is a problem but when. Converting to pci-e cables normally are also not very good gauge cable, add that to mix as well.

Avoid this just like no name low quality PSU's.

Try not to get no-name PSU's, as they can fry basically anything.

I totally agree, but does Cougar really classify as a no-name? That's the question...
Also it is Gold certified so that helps.
