Great article!

Now we need somone to blow up a crappy multi rail psu, so we can have balance.


I am afraid that this thread will create a giant exodus from single rail PSUs, when in reality, they can be fine

They can be. I'm just driving home the point that, hey, on high-wattage units single rail isn't really a benefit.

And if a power supply has multi rail OCP that's properly configured then it should be pretty hard to blow it up.

Stay away from Ultra. I had a 600W PS die within the warranty period and they refused to replace it. They insisted I get it done through the place I bought it, which was not a possibility since I had moved. Ultra low quality (pun intended) AND bad service = Fail.

Nice read lol im glad my psu is muti rail not sure how much protection it has tho. From what i know about my psu its a single rail but using ocp to split the rails as needed so i would think im safe from stuff like this.

Not trying to argue the point, but how was it the fact that it was a single rail PSU result in it doing this? Could it have not just been the protection failed? Or do all PSU's with a single rail have this protection removed? I mean I have strong confidence that my single railed 650watt PSU is not going to have an issue. But you have to ask, was the PSU being a single rail souly to blame for this failure, or maybe a combined effort of different things that made this happen.


My other question is, why in the world did he need a 1600watt PSU. What was he running to need that much power? Wouldn't having a PSU that is too high of wattage also cause the PSU to be able to put out way more current then is needed to fry everything. I mean his PSU could have spiked into the 2000watt range before dying, while my PSU if put under that situation probably wouldn't manage to put out more then 1000watts before killing itself. So would having too much wattage also be helping the PSU kill itself worse?
