The "Overclocking failed" message is triggered when the computer fails to POST for any reason. Doesn't have to be OC related.

Looks like pretty much the same guts as the PS480X2 I reviewed here: http://www.overclockers.com/logisys-ps480x2-review

It violated ripple specs at the first hint of load. Couldn't make it blow up...

Those caps are indeed crucial, I've tested with and without 'em.
On my scope they're worth >100mV of transient reduction on most PSUs. >200mV on some.
If they're lacking them, the transients have...

CPUs vary, widely. Some 8350s can't even get past 5GHz without extreme cooling.
I doubt you'd get any further even with Gods Own PSU.

Testing SCP is fun. I use a chunk of steel across a couple contacts fed by the CPU power cable.

If it's a non reference then overclock away!
Still won't max out 1080p though.

Overclocking a reference 570 is asking for fireworks. You'll need a new GPU to max out at 1080p. Wait for the game to come or before you buy anything.

Wouldn't surprise me.
Here's the TX750M: http://www.techpowerup.com/reviews/Corsair/TX750M/4.html

I'd like to put one on my test rig/scope and see what it looks like compared to the smart-m-750.

Looks more or less the same as the Smart-M 750. The corsair TX750M uses the same platform but swaps the synchronous 12v board for schottkys.
They swapped out the sealed inductors on 5v/3.3v for wire...

I don't see a classic rectifier.
Maybe two APFC circuits acting like synchronous rectification of the incoming AC?
The commentary is clearly a non-PSU person (inductors being called capacitors),...

Really doesn't matter if you aren't doing any extreme overclocking.
If you're running a voltmodded, OCP/OVP-free GTX480/580 on liquid nitrogen cooling, then it matters.

What I've found is that it's often a combination of GPU and PSU that is noisy, likely due on the GPU end to the frequency of the VRM bits as well as input power storage.

Asus says that it's...

It's worth noting that shiny surfaces don't radiate heat very well. You can see it with an infrared temp gun too. Two surfaces, one shiny and one matte that measure the same temperature with a...

Teapo primary and NCC secondary would be rare. They are that color, I've been running on the assumption that they're one of the off-brands that use the same color.

I have the impression that NZXT was responsible for enough of the HALE90V2 design that they have a lock on it. Could be wrong on that though as it is just an impression.
