Well it depends on what happens.
There's some truth to this, and this is one point where "MSI Got it right" (and yes, I die a little inside when I say that.)
Some of the high end MSI motherboards feature a PCIe 6pin Connector that adds power to the PCIe slots to aid the ATX 24pin connector, which is supposed to supply 75w to every physical PCIe x16 slot through 3, 12v wire.
(If you know even basic electrical principle, this is a bad idea when you have 3 or more PCIe x16 slots.)
Some motherboards add a molex connector to the equasion which is supposed to help; though that's only 1 additional 12v source.
Though, the issue that occurs can be stopped by a PSU that has many "virtual" rails (As defined by OCP Circuits.)
As the OCP would trip, preventing any damage.
This may make it a bit hard to load balance depending on the application, but it can be done.
The Strider 1500w does have OCP. So it would be a safe option.
EVGA has had this problem, and offers a sorta..DIY solution
to it. Which if you added this, and used the molex connector present on a motherboard; then you'd only be adding in 1 more 12v source, unless you used 2 different molex cables.
Though; this is not to say Single Rail units are un-safe, it's just that multiple rail units are more safe.
The Antec TPQ-1200 & HCP-1200 also have OCP and should be fine. Though, the OCP trip points are at 50A on each unit. Which is a little high for my tastes, testing has shown that above 40A and it's generally useless and 36A is "safe-limits." Though, no official or proper testing has been done on this.
The Silverstone STrider 1500w has it set at 25A which is perfectly safe.
The Sparkle Gold Class 1250w features these "virtual" 12v rails, though no defined OCP Set point.
The Enermax MAXREVO 1350w
does as well, with OCP Set points at 30A.
The Enermax S-Galaxy EVO 1250w
does as well, with OCP set at 30A.
Like I said; it's not really a huge issue (as most of the time, it melts the motherboard power connector but doesn't damage components beyond that.)
With patience and some solder skill you could potentially fix that issue.
There's also the Kingwin Mach 1 1220w
which has it set at 35A and another solid option.
