SF600 Platinum – Overshoot Transient Tests
VSB On VSB to Full, 12V Off to Full, 12V

And I am pleased to report the good news extends to this page, too. Power on spike testing shows what could almost be a wee spike on the standby rail, but is too iffy to make that call. The 12V rail looks flawless. So, I think we can let Corsair have full marks on these tests today.

Let’s heat up the hot box and see what happens. This unit is rated for forty degrees, so that’s what I’ll go for.

* Fanless operation.

Once more, we have easily cleared Platinum, and the tests that got all the way to Titanium cold are still there now. Fantastic!

Fanless mode lasted about as long as it did with the cold tests, but that’s ok with me. Again, with power supplies this little you need to temper expectations just a bit.

But not when it comes to voltage regulation, because we want the good numbers there. And this unit obliges by improving on the cold tests. Now, I see 0.39%, 0.20%, and 0.17%. That’s 0.25% average for the scoring page later, which is well inside the mythic level requirements for me.

This thing is ridiculous so far. But let’s find out how good the ripple suppression is before we lose our minds.

Oh, well, there you go then. 8mV at most for the 3.3V rail, 11mV for the 5V rail, and 16mV for the 12V. Excellent numbers all the way across.

Want to see the insides? I know I do, so let’s take it apart.
