Im sure i read an article a while back of you telling people that single rail and multi rail powersupplys are the same, neither are better. now your telling us that single rail powersupplys are crap....

If you have a single rail psu then

It means that it's lacking a protection set (or that set is poorly implemented)and

multi-rail is mildly better, especially with high wattage units.

[H] recently tested the single rail Corsair AX1200, but they had an accidental short circuit, and since the PSU's OCP is set for over 100A, the short overloaded and destroyed most of their testing equipment.



You have really gone and done it now phaedrus.

You can read the review here.
With only 4 rails at 20A a piece, with a high-end SLI setup, you can certainly find a way to make things "work", but, it's going to be messy, and you're going to have to sacrifice cable management inside your case, because, there will not be many "options" that work with what connectors need to go where. Plus, with compoenent degredation over time, I would not be confident in overclocking such a rig utilizing this psu once the psu gets older than 3 years.

Yeah, assuming you have something on the order of like SIX rails or something. That's not going to be cheap to find that psu.

Just because the vast majority don't know what "OCP", the fact of the matter is, if you asked them, which do you think is safer, single rail or multi-rail, unless they're complete buffoons (so, I am talking about enthusiasts here), they all know that multi-rail has always been more safe than single rail.

Sure, you're educating them about OCP, but, your article was written with bias, which is having the (unintended?) affect of causing many people reading this thread to not see any practical advantage of a single rail psu. Such as the poster right below you:



The fact of the matter is, single rail is preferred by gamers over multi-rail, for a variety of reasons,
1) to get a decent performance out of each, single-rail is CHEAPER
2) except for psus with massive amounts of amperage on a rail, who really cares about decreasing your chance of failure from 0.0001% to 0.00001%? Most gamers upgrade often enough so that they don't even run into failures caused by time-degredation.
3) For most psus which provide mid-range performance, multi-rail simply doesn't provide enough amperage on at least one of the rails. Unless you go very high-end for multi-rail, you're likely going to be choked somewhere.
Hannedog, you're wrong about OCP, plain and simple. I don't know where you got the ideas you have, because I've never seen anyone with quite the belief set you do in regards to this. I honestly don't know where to start breaking down your misconceptions because I don't know where their root lies. Perhaps you debated someone over this years back and he either didn't understand multi rail OCP or argued it poorly. I don't know. Fact of the matter is, you're spouting the type of FUD that grew in the wake of PC Power & Cooling's "myth" page.


The fact of the matter is that PC Power & Cooling's FUD about how single rail is so much better/more reliable/safer/more stable took extremely deep roots into the collective knowledge base of the tech world, and everyone believed single rail was better and safer. That's been the "common sense" viewpoint for going on five years now, with perhaps 2-5% of the community disagreeing.

Articles like this are the dynamite to blow out those roots. Maybe there will be some collateral damage, but the myth will be gone. And who knows, maybe in five years the idea of "single rail bad" will be so deeply ingrained that someone else has to make an article countering mine. Who knows? The difference is that PC P&C made their articles to sell a product, I'm making my articles to educate people.



Anyway, single rail power supplies have no inherent advantages over a multi-rail PSU, unless the multi-rail PSU was designed by someone who didn't know what the hell they were doing.

Great article!
It's a good thing I didn't buy another crappy ultra PSU. My last ultra 650w blew up and I vowed to never buy another ultra PSU. Even tho my kingwin PSU is single rail, it's still a really good PSU. Jonny guru recommended so I'm good.

Good read and with nasty pics. Another thing I believe we can add here is that a LOT of motherboards aimed at overclockers are severely lacking in the VRM department.
