Is this PSU good enough to power a overclocked antminerS1?

Generally you want to give your PSU some free overhead. 34amp potential load is probably a bit too close for comfort for the standard clocked S1 which is rated at 360w or 30amps. So is it good enough, well probably not, but would it work, well lets say, theres a 50% chance it might run an S1 if as stated previously, you added on the ability to connect this PSU to an antminer. Antminer S1s require your PSU either has 2 x PCI-E leads or you have to cut some of the leads up and manually wire them in.
So unless theres someone else on these forums that has used that particular PSU, I'd recommend you give that one a pass. Most PSUs that have 41, 42 amps or more on a 12v rail will run an Antminer S1, and when I say most, that means, not all of them do.
For example I have a brand new Corsair VS 650 that supposed to have a 50 amp 12v rail, but will not run an Antminer unless its underclocked to 325 MHZ. I am not saying that model will not run an Ant, but this particular one I bought struggles to do so. Also have an Enermax 500w that supposed to have a 41 amp 12v rail, but cannot keep an Antminer running even underclocked for longer than 30 seconds.
But I also have several AcBel G600 550w PSUs that have 39 amp on a 12v rail and no problems at all powering the Antminer S1s even overlocked to 393 MHZ.
Yeah so its not always a guarantee even if a PSU meets the specs that it will perform. Partly the reason why many miners go for something between 550w and 750W range with at least a 42amp 12v rail or more, chances of one of those not performing as promised is quite low, but it can still happen.
