Cables / Internals

Three strands of SATA power cables are included, each with three connectors for a total of nine. Two additional PCIe strands each provide 6-pin and 6+2 –pin connectors for a total of three 6-pin and three 6+2 -pin connectors.

There are also three 4-pin Molex strands. Two strands have three Molex connectors each. The third strand features two Molex and one floppy style connector. Note that the Molex connectors feature quick-release connectors.

All of the connector terminals on the power supply are gold-plated to maximize contact resistance.

Heatpipes inside a power supply are pretty uncommon but it looks like Zalman has done a good job with the implementation here. Safety features on the PSU include Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection.

We see that Zalman is using Japanese-made capacitors along with Active PFC (Power Factor Correction). Additionally we see four +12V outputs and the large 140mm dual ball bearing cooling fan. The fan is solid black and lacks any LEDs so it won't clash with any particular color scheme (or lack of) that you may be working with.

I checked the OEM for this power supply using the UL certification number but Zalman had their name registered with the unit instead of the actual manufacturer. I did some more searching and came across two possible manufacturers: FSP Group or Enhanced Electronics. I was not able to confirm either one as being the true manufacturer, so I will just leave it at that.

Let's move ahead and take a look at the test system and put a load on this power supply.
