They know about this; but single rail units sell better.

Seasonic's last gen premier product (S12D Platform) had 2 12v rails derived from a single source, and split up using OCP.

Antec & Enermax are two of the few companies that offer a full feature set of protections on almost all of their units.

Antec does know that a single 12v rail sells better, which is why the Antec NeoECO units have a single 12v rail (besides, no OCP is stock for that platform.)

The frequency of the occurrences, like what's listed in the OP, are small. This is why most companies would rather take the easier method to sell their units, and just claim a single 12v rail.

Some companies try to confuse users though, by saying they have multiple 12v rails when they do not. Or not listening a combined 12v amperage/wattage, so your average consumer will had up four 18a rails and think their unit can do 72a on it's 12v rail.

So basically that coupled with a low pwr phase motherboard (4+1) such as mine is very bad for overclocking?

Really? Wouldn't it be fine if I left it at 1.39v/3800mhz? (aka not overvolt)

The number of phases a board has for it's power design has no indication on quality. A phase is simply a channel.

More phases is generally better as that means you have more MOSFETs distributing the load.

Though most power designs with a greater than 4+1 Phase Design, usually are just compounded 4+1 Phase designs.

Meaning some of those 16+4 Phase designs you see are just four, 4+1 Phase designs working in tangent.

As for if it's a time bomb or not, it depends on the failure, how it happens, what you were doing, etc. Multirail will give you more protection in various failure incidents; but single rail isn't as dangerous as it seems.

Yes it's true.

No one checks documentation most of the time. They also do not need to be certified to say that.

Some older Corsair units were labeled as having multiple 12v rails, but they only had a single 12v rail. This was Seasonic's fault, not Corsairs's. Seasonic told Corsair that the units had multiple 12v rails when they did not.
