Yes, it should power one but you are always best to go for a brand name psu. With a brand name you usually find better components inside as well as better coverage on the warranty.

What is it that determines if the PSU is suitable. Is it the overal wattage,

look at the 12volt rail

34 x 12 =  408 watts .  At best

  I would not use this psu.

Thanks, so using that formula. What is the minimum watt on the 12v line should be used

You can find good Charts here: https://bitcointalk.org/index.php?topic=486121

I just picked up a Corsair CX600M for my S1. On Monday I will use it for the new S3 ...

[jbmac1967]

Also seen it is advised to connect 4xPCI-E slots to the S3, but most of the PSU i have seen only have 2 PCI-E

Tired searching but there is just SO many pages

[Atomar]

S3 does NOT require 4 PCI-E. 2 are OK unless you OC' it

[jbmac1967]

Thanks atomar

So just connect a PSU into each "set" of PCI-E slots on the antminer

After looking at the 12v rail and doing the calculation

What is the minimum power needed to run an s3

[jbmac1967]

What sort of power is needed after using the 12V rail calculation

[allcoinminer]

After looking at the 12v rail and doing the calculation

What is the minimum power needed to run an s3

Ideally you only need 340Watts in +12V rail if S3 is running at stock clock.
340Watts in +12V rail means 340/12= 28.33A. This is in theory.
But when you run a load for 24hours every day and in practical considerations this 28A in 12V is not sufficient.
The PSU sizing may be done by making the rated load to 125%.
So, the antminer consumption should be considered as 340*1.25 = 425Watts.
So select a good branded power supply were their +12V single rails is giving at least 425Watts or 35A.
