Hi guys,
I am here to answer some questions... some of you might know me from AnandTech, where I was writing PSU reviews for the past couple of years. I am going to answer a few of your questions and hope you will read until the end!
So, where to start... first of all, it's easy to brag as someone before me said already. You need to understand the whole thing to get the picture. In most cases nobody really understands the issue with OCP. I mean we showed some video on our
YouTube Channel about PSUs without OCP. There wasn't anything made up. You can see a motherboard frying up. We have more videos about this, different cases but all the same result about something burning up.
I am reading in more and more forums in Europe that people have melted wire isolations, connectors and other parts. This has only one reason: If you create short circuit in your system with a PSU that doesn't have OCP the current can flow unhindered through your system. Why some guys above say that it's made up? Guys... open your eyes. Without OCP the current flows and since the wires can only withstand a certain current they start getting hot and melt off their idolation, or the connector melts and so on... Just imagine you have a short circuit on the motherboard... you can see that in the video. Your components will be simply fried up. That has nothing to do with false panic or hyper-marketing, that has something to do with safety and us telling you about it.
You would feel good if you buy a car without airbags? Building a house without circuit breakers? It's exactly the same thing with OCP. You might never see an airbag, never break a fuse. That doesn't mean they are not there and IF you need them one day you are thankful that they actually have been there!! With 99 people it might be ok, they might bever have a problem so they won't need OCP on their 12V rails, but the one guy... the one guy who actually short circuits his system and fries up all of his components will be very unhappy about it, right? You wouldn't want to skip on an airbag either. So only because you never had a problem doesn't mean it's all perfectly safe.
And to make sure you understand, there is not any high-end single rail power supply (in the upper wattage range) that comes with OCP on the 12V rail. COmpanies writing this safety feature on their website write this because they have it on the 3.3V and 5V rail and want to trick the users, nothing else!
This myth-series is there to educate you, to teach people in a hopefully easy to understand way how the things work. There is simply no need for single rail power supplies (As always I mean single 12V rail with high amperage) today and in addition they are simply dangerous.
Think about it, I am here for Q&A
