You only need to read a few pages back to discover that miners (including myself) have successfully been OC'ing S3s with mere 500W PSUs with only 2 PCIe power inputs.

Yes, I've been following this thread since the beginning. ("discover" - really? Nice.)

But I'm talking about his results and the fact that his situation with his 650 matches my experience with a wimpy 850. The QUALITY of a PSU is more important than the rating above a certain level (and 500 sounds about right for a really good high-efficiency PSU).

I'm not as concerned with the 2 PCIe inputs as I am with good PSUs. But if you have a weak one with separate weak or marginal rails, then 2 inputs per blade could very well help. My thought is that it is the "sag" the poorer powersupplies experience with a strong maintained load that is the problem.

Back in the day with AM Cubes, we had the same persnicketiness with the quality of solid, stable PSUs. I had a couple of server 750s that would each run 2 OC'd Cubes no problem at a time when folks sometimes couldn't get their Cubes to run with a single 750 (or even 850).

This is not my first rodeo, but thanks for your kind input. I stand by what I wrote, and I think he would be well-served to try better (or more) PSUs - it worked for me, and his stated symptoms match what I was seeing.

Yes, "really". I was responding to your post at face value (I honestly thought that you didn't have a clue) so I attempted to let you be aware of a fact. That's all. If "discover" touched a nerve in you, that's too bad. If it makes you feel any better, I hereby retract "discover" and substitute it with "find out".

It's not "first rodeo" for the majority of us in here either. Therefore, the common knowledge that the quality of a PSU affects its performance is nothing new in here (or any decent tech forum for that matter) and is not exclusive to you.

To reiterate, contrary to your post (verbatim) that I originally responded to, it's a fact that the S3s have been successfully overclocked using 500W PSUs utilizing only two PCIe power inputs for each unit. I refuse to allow disinformation to propagate.
