We’ll start with the internal shot this time, just to get it out of the way that we’re looking at the same Seasonic platform we’ve already seen several times before.
An FDB fan greets us here, and with a good long warranty we shouldn’t need to worry about it holding up.
Two Y caps and one X cap start the line filtering.
And we continue our line filter with a MOV, two coils, one X cap, and two more Y caps. Two GBU1006 bridge rectifiers can be found next door.
The PFC parts. One diode and two GPT18N50DG parts on a heatsink with the PFC coil directly behind said heatsink. That black box there is a relay used to short the NTC thermistor for extra efficiency. Most Gold or better designs use those, which are responsible for the clicky clicky noise you might hear when powering these up.
Soldering quality is excellent, as usual. A WT7527 can be found here for protection, with the usual CM6500 and CM6901 combo for PFC and PWM control.
12V output is provided using two PrM 1808 C4 parts that were super hard to get the numbers off of.
Four of these GPT13N50Gs handle switching duty.
Of course, this is no ordinary Focus Plus unit… there needs to be support for the software interface, and that’s done right here on the same board we find that nightmarish little bastard of a fan connector. A UCD3138064A is our digital power supply controller of the day.
A PIC16F1454 is found near the USB connector of this unit on the other side of the modular board. The connector nearby likely enables programming the chip at the factory, and is not accessible from outside the housing.
Finally, the modular board. All capacitors are either Chemi-Con or Nichicon, so I have no concerns about their quality. Let’s go get the scoring done.
