EVGA 750N1

Hello, fan. Goodbye, fan point. I’d have little confidence in this fan lasting even if the unit did have the five year warranty I require to keep the fan point.

Yep, that’s a HEC built unit. It does look more robust than the Cooler Master, but then it would… since this unit has to work at North American line voltage, it needs a beefier primary side.

Line filtering starts with two Y caps, one X, and a coil.

Soldering looks good but not great, so I can see me pulling half the soldering point later.

Line filter continues with two more Y caps, one more X cap, one coil, and a TVS diode. A little basic, but it’s not bad. A WT7527 handles protection.

Yes, those are Elite branded capacitors next to those two Teapos. Third tier caps mingling with second tier. But at least Teapo gets to do the critical stuff.

Two 15A bridge rectifiers can be found here. Given the numbers we saw on the second page, I’d say thirty degrees is as realistic a max temp rating as twenty-five. Not sure why EVGA and HEC would rate the unit this low, though I stand by my assertion that forty degrees is a no fly zone for this unit.

A CM6800 handles PWM and PFC control in this unit.

Being group regulated, we get the old familiar two coil arrangement on the output. Big coil for 12V and 5V, little one for 3.3V.

The main filter cap is also from Teapo, and only rated at 85 degrees. I’ll be scoring that. Sometimes it’s ok to have parts so rated on the primary side, but I don’t like to see less than the 105 degree parts everywhere. So, I’ll keep scoring it as long as I’m here to score things.

By the way, sir, that haircut? Easy 9/10. The beard gets 1/10 though. Not a beard guy.

On the primary heatsink, we find four FDP18N50s alongside the PFC diode. Two for PFC, two for switching.

Finally, here’s the secondary heatsink. Four PFR40L60CTs for the 12V rail, and two STPS30L45CTs for each of the 3.3V and 5V rails.

Scoring time!
