Here are a few pictures showing the layout and components inside the Zalman ZM750-HP 750W power supply. The overall build quality appears to be very good. One of the main heatsinks has a copper heat pipe attached to conduct waste heat away to an array of aluminum fins that are cooled by the exhaust air flowing over them as it leaves the backside of the PSU enclosure.

It appears that Zalman has once again selected Seasonic as their OEM for this particular model. Seasonic has an excellent reputation for building some very good PSUs, especially in the mid-power level class.

The primary section uses a single OST cap rated for 470uF, 420V and 85°C. The main bridge rectifier and APFC regulators are mounted on a common heatsink without any assistance from heat pipes.

The secondary side of ZM750-HP power supply is populated by Teapo and CapXon caps and is dominated by a lot of distribution wiring. No solid polymer caps are used in this build.
