PowerColorSomething very special coming up in May... dare to guess?

Wonder how this thing would do at Bitcoin mining?

LOL

Badly, coins are near dead. Look for x11 coins it seems.

Life on the enthusiast edge comes with its niggles though. Separates the men from the boys!

I realize you are grinning , but...

Reading what JonnyGuru had to say, it's because you don't always have an even load and too much fluctuations on the two connectors. This makes the PSU think there is something wrong and it shuts down.

Keep in mind that he is now employed by Corsair, so there could be some spin in what he is saying as well. He does have a sterling rep as a journalist though and I'd hope he wouldn't go onto the site that bares his name and tell porkies.

You do (edit: talking here about having to turn off OCP). We tested it here measuring the current to each connector as load increases and it seems that the 295X2 doesn't "load balance" across the two connectors. Almost as if the +12V and ground don't share the same destination on the card's PCB (I haven't taken the card apart to double check). The load gets really high on one connector and then, just as the resistance is high enough to cause a drop in voltage, you start to see more power going to the second connector.

This forces you, with the AX1500i, to have to turn off OCP to circumvent the protections. I personally wouldn't want a single rail that's capable of 125 amps in my PSU anyway. I'm a multi rail believer. I sure as hell don't want 125 amp 12v rail with no OCP protection.

Either Corsair took a shortcut on how they implement their OCP and it's coming back to bite them, or it's really poor engineering driven by marketing. Judging by what happened on [H] where the 1350W Platimax also shut down (which is a multi rail design), knowing they are operating these connectors out of the accepted pci-e specification, and AMD marketing's reputation, I'm leaning towards blaming AMD on this one.
