ADATA HM-1200 1200W Power Supply - Cabling Arrangement & A Look Inside

Cabling Arrangement




With a total of 15 different cables, ADATA serves up quite a bit of connectors in a wide variety to make sure that you can power anything and everything. Dual EPS12V connectors allow the power supply to function in high end systems with dual processors and server boards. There are a total of six modular PCI-E cables to provide power to triple GPU systems. If that isn't quite enough for you, ADATA includes a pair of dual Molex to PCI-E adapters that will let you power up a fourth GPU. In case your system is filled to the max with optical and storage drives, the HM-1200 has eight Molex, eight SATA, and one FDD connector.




We did notice a discrepancy between the connector availability listed on the box and what was actually included. While the box lists two modular cables with 4+1 Molex+FDD and a single SATA cable with four connectors, the box we received had only one 4+1 Molex+FDD cable and two SATA cables with four connectors.




The HM-1200 features dual 600W 12V rails. 12V1 is dedicated to the six PCIE connections available, while 12V2 is dedicated to everything else. As stated before, this is denoted by the red/black labeling surrounding the modular plugs on the front of the power supply. While this isn't stated anywhere on the power supply, box, or ADATA's website, it is denoted in the user manual.



A Look Inside




Once we crack the HM-1200 open, we can see that ADATA has made sure to utilize as much area as possible for heatsinks in order to help dissipate the large amount of heat generated when the power supply is under full load.




Both the primary and secondary of the HM-1200 feature Japanese capacitors. On the primary side we can see Hitachi HP3 caps.




The secondary side is filled with Nippon Chemi-Con capacitors.
