Try not to get no-name PSU's, as they can fry basically anything.
If you're determined to go with ATX over a server supply, I'd go with the Cougar over the Corsair. The CX series is only bronze rated and as you pointed out, the Cougar is Gold which will save you in the long term on power usage as well as put out a little bit less heat at a given output. I had that exact PSU a while back running an 850ish watt load 24/7 and it was a tank up until I sold it. The extra maximum wattage will also give you more headroom for another miner or for overclocking later, which might be pushing the 750 a bit.
I'm already pushing it a bit getting the S5, in relation to noise levels, so I really can't deal with adding more noise with a server supply.I have also bought a couple of Corsair SP120's so hopefully they will make the noise somewhat bearable...
I'm also leaning towards the Cougar so it's good to hear your feedback about it! Thanks
Ah! Well good news for you there then, the server supplies that I have will be actually quieter than the S5 at that load level(when you get close to max load they'll probably be about as loud as the S5, however). And cheaper than the Cougar. And have higher peak power and will also be Platinum rated instead of Gold. Downside is, it's a miner supply only, just PCIe output and nothing else.
But if you do still want the Cougar I'm sure it will serve you well. Can't really speak to volume level though, I never paid attention as it was in the rack the whole time, not in the house.

Thanks very much for your input guys, appreciate it!
I have narrowed my search down to the following 2 PSU's -
Corsair CX750 (~$116)
Cougar GX1050 (used) (~$136) link - http://www.newegg.com/Product/Product.aspx?Item=N82E16817553008
Bear in mind these items are expensive where I'm located, hence above prices are a bit higher than you'd expect...
The Corsair is recommended by a lot on this forum, but the Cougar has some good reviews and is also Gold-rated

Hi, take a look at Dogies PSU guide with specs: https://bitcointalksearch.org/topic/guide-dogies-comprehensive-power-supply-analysis-486121
I mentioned the Corsair modular PSU's which I have used to power S1's & S3's and they worked fine. I haven't had an S5 though.
I think you'd probably need the RM1000 from Corsair to power an S5 adequately and safely because they require 4 x pci-e connectors ( 2 for each board ).
Alternatively look at the other brands or server PSU's that people have mentioned.

As far as PSU's you cant go wrong with RM1000's, EVGA Supernova 1300, even have one Rosewill Lightning 1300W. None of these have ever given me a problem. I have quite a few of the RM1000's at this point.
Keep in mind I use these as I had them here. If your buying PSU's the current trend is to go for server grade ones over standard ATX. If you have 220/240 this new wave will be especially beneficial to you.
See sig for quality 1100w platinum PSUs that will run on 120V. When they're not loaded near max they're actually fairly quiet. The S5 itself will definitely be louder.

Actually, most server supplies are just fine for GPU rigs also, provided you have an external-on signal line which can kick on the supply along with your ATX. My breakout boards and I believe pmorici's do this. Heck, I got into server supplies by refitting them for automatic extra rails in GPU rigs.
Also, if he's looking for quiet fans for the S5 a server supply could easily be too loud. Something to consider.

and this PSU only rated for 30C intake temp for full power output - http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=416
CX750M only have 2 pci-e power cables and they are 18AWG and it is only bronze efficiency definitely not suitable for mining
and right now I'm looking to get something similar to the Corsiar CX750.
Don't buy M (modular) version for mining
hi , got some seasonics 1000w platinum ( several units ) and other models too..
just Pm me in case of interest
Cheers !

Sorry it took a while to respond to this guys.
Couldn't have asked for better responses!
My S5 is being shipped as we speak, and right now I'm looking to get something similar to the Corsiar CX750.
Now on to my next decision, quiet fans :-)
2x Noctua NF-P12 or 2x Scythe Ulta Kaze
or
use both w/ push/pull....

So really it comes down to what type of electricity you have 110/120 or 220/240. And also if you plan on expanding it appears from conversation.
If you plan on stopping at 1 S5 a lot of these are overkill. But if you think chance of adding more getting a bigger PSU makes sense. And no matter what get a decent brand or server psu. It will make your life much easier.

I say evga 1300 g2 or server psu's.
I think you are not in the USA so pricing and other rules vary.
The evga 1300 g2 can run 2 s-5's and has a 10 year warranty in the usa.
mine have run s-1's s-3's and s-5's
server psu's are cheaper and run loud, but s-5's are nut job crazy loud . think shop vac loud.
that's my 2 cents.
oh but the server and the evga will do 240 volt

I can recommend Corsair PSU's for running mining hardware if you're looking for ATX type. Most recently I've used CX500, CX600, CX750 (go for the M or modular because it saves on bundles of wires everywhere), RM1000's and AX1200's most of which I picked up on ebay for a good price, used for a few months then re sold them on ebay for the same money.
Branded PSU's are one of the few items associated with mining that doesn't depreciate in value that much as they will always have a good second hand resale value.
Also as already advised go for one that too big rather than too small, its better to have one with power in reserve than one running at its limits for 24/7 because it wont last very long.
Another thing worth considering is their efficiency rating. You can obviously get bronze, silver, gold and platinum rated PSU's with bronze being the cheapest to buy but least efficient and the platinums the opposite. Bronze are absolutely fine though for running mining hardware.

The rating on the PSU is what it can safely supply, not what it's always pushing. An S5 will draw around 600W, meaning that any PSU over 600W rated should, in theory, work (though running a PSU, especially a cheap one, at or near rated load for extended periods is almost guaranteed to burn it out). The particulars of how much it actually costs to run (power bills) are based on PSU efficiency, which is usually a fairly flat curve peaking in the middle of rated load and drooping maybe 3-5% at the upper and lower ends. So to get the best possible, you'd probably want to find a Platinum-rated (peak efficiency about 93-94%) PSU rated for 1200W, so your 600W S5 will sit right in the highest efficiency. Where I live, the difference between about 85% and 90% efficient for an S5 adds something like $30 a year to the power bill.
I also recommend taking a look at server PSUs. If noise isn't a problem (which I hope it isn't since the S5 is probably louder already than most server supplies) there are some really good efficient supplies to be found in the 750-1200W range from sellers here on the forum and they love running on 220V power.
