That being said there is a recent change of a lot going with server PSU's. With these you can get a quality PSU (in a lot of cases) cheaper then a ATX power option. If you have a 220/240 I would seriously look into this option.

I believe the domestic supply in my location is 220/50hz so I will look in to these server psu's you mention.

It will only draw what's required. Most high quality ATX supplies will run quieter when not fully loaded.

When you say they only draw what's required, does that mean an electricity bill for an S5 would be the same across both a 750W and a 1500W PSU? Ie. does a larger PSU increase electricity costs?

Personally I think "overkill" is moderately appropriate when choosing a PSU for the long term. My understanding is that most current high quality supplies have a fairly wide efficiency band. There is absolutely no reason to load a PSU to 90% in order to make it efficient rather than say 60%. It will only draw what's required. Most high quality ATX supplies will run quieter when not fully loaded. There are tangible benefits:

- A higher quality supply will usually have better, possibly 16AWG cables to connect to the miner. Lower cost PSU may have lower quality (i.e. 18-20 AWG wire) cables.

- Generally they are more durable, and withstand unexpected demands better (temperature, etc).

- Should have better resale value later.

I expect that used Server supplies are very available, and can work well, though they tend to be noisy.

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.

I personally would say get a quality PSU and save yourself some trouble. It does not have to be some huge massive psu, but one from a good brand. I personally like to get a PSU that would power 2X of the item. In your case S5's, that way if I want I can order a second one and easily put it in.

A quality PSU can last longer then one generation of miner's even. So it can be considered a longterm investment.
