Cabling Arrangement

Zalman provides a great selection of cables to go along with the ZM1250. Dual ATX 4+4 and EPS12V connectors are available for those who need it, though it would be nice to see one of these available as a modular connector so that excess cabling could be removed if it isn't needed.

Two different types of PCI-E cables are provided. Two of them have dual PCI-E connectors while the other four feature only single connectors. Peripherals are handled via 12 SATA connectors over three cables and nine Molex connectors over two cables. There is a single FDD adapter included should it be needed.

Rail distribution is simple for a dual rail power supply. The first 12V rail provides power for the CPU, motherboard, and all peripheral connections. The second 12V rail handles power for all PCI-E connections. It doesn't get much simpler than this and is spelled out on the I/O specification label for the user.

A Look Inside

Passive cooling is handled via multiple heat sinks around the unit. There isn't any fancy heat pipe cooling like we saw with the ZM1000-HP Plus, but rather solid pieces of aluminum to draw the heat away.

A pair of Nippon Chemi-Con capacitors reside on the primary side of the Zalman ZM1250 Platinum power supply.

Ong Hua provides the active cooling fan for the ZM1250. The HA1425M12B-Z fan is a 140mm ball bearing fan.
