Is this unit looking smooth and continuous to me? Yes it is. Super Flower is one of the rare companies who keep on top of things here, and these shots show why that matters. We like smooth and uniform ramps up to full operating voltage on the outputs, and that’s what we got here today.
I have a feeling this unit’s going to score well, but we do need to make sure yet by heating things up. Let’s crank up the hot box now.

Sadly, this time out the regulation wasn’t quite as good. That does tend to happen at times when the heat starts blasting. But even so, the numbers didn’t move much. The 5V rail stayed at that same 0.60% number, while the 3.3V rail went to 0.82% and the 12V ended up at 0.33%. That still works out to a comfortably excellent and still near mythic average of 0.58%. Pretty darned impressive for a unit in this market segment.
And you can tell heat wasn’t a major factor, either, because the efficiency numbers have stayed pretty well the same. This unit still clears 80 Plus Silver.
The fan worked roughly the same amount of time, as well.
|750 B3 750W – Oscilloscope|
Oh, now this is getting ridiculous… ripple control this good, helped along by those extra in cable capacitors, is definitely not expected at this market segment. I’ve got 6mV on the 3.3V rail, 8mV on the 5V rail, and 7mV on the 12V rail.
Huh… maybe I should start throwing in a mythic level bracket on these. If I can figure out how to rebalance the rest of the scale, that is. Currently, excellent is 25mV or less, very good is 50mV, average is 75mV, below average is 100mV, and mediocre is the 120mV ATX spec. If I did a mythic level, it would probably be 10mV or less, average. Anything much less approaches the limits of what can be measured without confusing it for normal background line interference.
Enough about that. Let’s take it apart.
