A cx600 would be useless to over clock a s3! I need 2 cx750 to have two overclocked s3s

Why do you say that? Have you actually run an S3 with a CX600?

Even if an OC'd S3 draws 450w at the wall, it only represents a 73% load on the CX600.

That's not really how power supplies work. Overall wattage is not the representation of how much power it can give on the 12v rail.
The cx600 has a 46A on the 12V rail, this is 552watts. That's 81.5%load without the added power draw from the wall minus efficiency of the power supply.
Seems it only comes with 2x PCI-E adaptors, so you would need molex to PCI-E or sata to PCI-E if you wanted to connect all 4.

OK...let's make this simple. A CX500 will absolutely, positively power an S3 at stock clock ...I've been running three batch 5s for two days now - avg 438Gh/s on the CX500's (I used 5 CX500s to run five S1s previousl - they draw nearly the same AMPs as an S3) The CX 500's are selling at Newegg.com for $29.99 after $20.00 rebate right now.

One PSU per miner means if one PSU dies, only one miner dies (not that any of my Corsair, EVGA or any other name brand PSUs have died since I started seriously mining about 5 months ago).

I don't get why y'all are buying these huge, expensive PSUs to support multiple miners...what's the point? And the next person that tells me they are buying gold or platinum PSUs because they are "more efficient", better be able to justify the additional expense vs. actual electric cost savings over 80 or so days...show me the math that proves the "more efficient" PSUs actually ROI better for our very specific scenario.

you want math here

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1407467214&sr=8-1&keywords=evga+1300

cost 188 rebate 20 = 168 for 3 s-3's or 56 for 1 s-3.

I paid 155 for mine which was 51.66 an s-1.

10 year warranty. you get 3 years. you pay 29.99 for your first one then 49.99 and 49.99.

your total cost 130 my total cost 168.

so after I am done with my s-1's I use it for my s-3's

feb to july s-1's
I still have 9 plus years warranty. These will be used for years to mine. how long is your warranty?

I use 1 power cord. you use 3 power cords. I get a quality psu trick switch which means if I burn up my house I can sue them.

you use a paper clip good luck with that in a court of law.

hey you want cx500's cool enjoy them.

you pull how much power to run at a 237 over clock ?

I pull 365 watts and can run 3 s-3's if I want

Thank you..that was an Amazingly stupid response without any math related to our very specific scenario...which is exactly what I expected.

Miners need to have a Return on Investment ("ROI") [apologies to any of you that have actual experience in finance - I realize this is a woefully bastardized definition of "ROI"] in about 80 - 90 days.

Take your "buy" price for the hardware (including miner, PSU, cabling, switches, etc), subtract your expected "sell" price for some or all of the above, add the value of BTC you expect to produce (based on your estimate of change in difficulty and your estimate of the change in the exchange rate between BTC and your local currency over your the period you expect to mine) , subtract your energy cost, subtract whatever you think your time is worth; and you have a rough "ROI" estimate.

Saying your PSU has a 10 year warranty is meaningless, unless your plan is to continue to use this PSU for 10+ years for the very specific purpose of mining. I pay $29.99 for each CX500 because I have at least a minimal degree of intelligence and realize that these PSUs go on sale with the same $29.99 net cost every 3 or 4 weeks. So I buy one whenever they go on sale; get my rebate card; and use it. Not exactly rocket science. I can get 5.6 CX500s for every EVGA 1300 you have.

Oh, and as to your "court of law" / "paperclip" comment...you really are a moron...before spouting nonsense about what would or would not become a successful claim, do even a little bit of research...please???
