And… nope, this unit looks just like the Titanium models. That’s unfortunate. The standby rail is just fine, but the 12V side of things isn’t smooth or continuous. So, half the point will be leaving on the last page.
Time to do some hot testing.

It’s not too often a unit comes in here and nails the same regulation in the hot tests as the cold tests, but here we are today looking at just that. Awesome! And at the mythic level, too! If only the MIJ unit had done this, huh? No disputing Seasonic is still the master, here, with relatively few other companies competing.
Efficiency was still a bit of a struggle in test three for Platinum, but it does clear once again and all looks fantastic.
Yeah, the fan got loud again. Let’s see the scope shots.
|PRIME 1200 Platinum – Oscilloscope|
Eeeeexcellent. Not that I expected any less. Though this model does have in cable capacitors helping out, it does manage some nice readings here so I reckon they can stay. I’m still going to score against those, though.
The ripple itself runs about 15mV max for the 3.3V, 16mV for the 5V, and 20mV for the 12V. Nothing to complain about there.
