Zalman Acrux 850W

You may think other fans are tough, but this one is bearing balls. Hmm, look at that. I just blew up a hundred different dad joke detectors.

A look inside the unit shows us a familiar looking Enhance platform. I do wish they would go to fewer high gauge wires over that spaghetti mess to the modular board, though.

Two X caps and two Y caps handle the first bit of the line filtering here.

Enhance usually does soldering really well, and this is no exception. I rarely see them drop the ball here.

Eight IRFH7004s handle the 12V output for the unit, sinked to the housing and through the board to heatsinks around the main transformer.

A PS223 handles protection, while a CM6901 handles PWM control duty.

Two more X caps, two more Y caps, two coils, and a TVS diode handle the rest of the line filtering.

PFC is done using the usual diodes and these 5R199P parts.

Meantime, four 5R280CEs handle switching.

Minor rail VRMs are done using an APW7073 controller, an 050NE2LS, and an 018NE2LS.

Capacitors come from all over, but are all the good stuff. Enhance loves to use Unicon polymers, and we find them all over the place today. Enesol also has a few in this unit.

Electrolytics come from all of the Japanese big three: Chemi-Con, Nichicon, and Rubycon.

Excellent soldering on the modular board, too.

And finally, the business side of the board. No connector space is left blank, despite the unit only coming with six PCIe cables.
