Not everyone needs an enormous 1000 Watt Power Supply. I mainly use my computer for Internet, some word processing, storing my digital pictures and on special occasions, play a video game or two. Finding any reviews on any low wattage power supplies is next to impossible these days. When I was given an opportunity to write about the Zalman ZM360B-APS, which is a 360 watt power supply I took the assignment and here are my thoughts.
Zalman Technologies was founded on 1999 in Korea and has a wide product selection that caters to reducing noise in computers to 20dB. Their products range from CPU heat sink with fans, power supplies, video card cooling fans, to high end cases for your computer and Home Theatre PC’s. Let’s find out how one of their less flashy little power supplies does.

Power Supply Specifications
What’s In The Box?
The box of the Zalman ZM360B-APS did not catch my eye. Being all blue made the picture of the power supply on the front of the box almost blend into the background. The text on the box, being white, did have the contrast needed to make it easy to read the information off it which helps in the buying decision.
Once I opened the box, I found the following items:
- Zalman ZM360b-APS power supply
- Dual fan connector (ZM-DC1)
- Power cord for AC power source
- Instructions manual
- Zalman cable ties
The Zalman cables ties were a nice surprise to see in the box. I am always going out to buy zap straps to tie up my cables in the computer. However, when I went to use these Velcro ties, they were too short. Hopefully someone at Zalman Technology’s would read this and change the length of their ties to at least a 9 inch length. But nontheless, they were a nice touch and because you don’t have to
First Impressions
When I pulled the power supply out of the box, I could not believe that I was holding a power supply. The paint and finish on the metal of the power supply made me think that I was holding a high end computer case and not a normal power supply. The honey comb grill at the rear of the power supply added to the attractiveness of the Zalman ZB360B-APS. The large fan in the power supply and the almost flushed chrome plated wired grill made the power supply stand out.
Cabling and Connectors
The sleeved cabling was a nice touch by Zalman, which made it easy to organize and separate all the power cables. It’s nice to know that even on a lowly 360 watt power supply, they still took the time to add this higher end feature. Even after hooking everything up and tidying up things by hand, it didn’t seem that I needed to use Zap straps or the Velcro straps at all. The sleeved cabling definitely makes things look tidy on their own, though tying away the cables anyway will allow you to increase airflow inside the chassis.
The number of different types of power connectors was nice to see in the Zalman ZM360B-APS power supply. Connectors include ones for dual PCI Express VGA power, dual +12VDC output, and SATA and standard HDD power connectors. Having these connectors make your video card and storage options a lot more flexible since you can run a higher end video card and either IDE or SATA drives right out of the box. I would not have expected to see these connectors in an entry level power supply Zalman Technologies, but here they were. The Zalman ZM360B-APS power supply seems to be a logical upgrade for any old power supply that has given up the ghost.
The easy grip connector is a great feature as well. In the cramped compartment of a computer case, pulling the power connector out of the optical drive was much easier with it than without. The instruction manual is better then most I have seen. The layout of the manual allows someone who is not familiar with computer power connectors to be able to look it up in the manual. This will definately help anyone who is not familar with the different power connectors.
System Setup
To test the how well the Zalman ZM360B-APS power supply would handle while being used on a real computer, I assembled a system that I would be used in most normal multimedia situations, but it definitely no gaming machine. The following components were used in the build:
- Intel E6300 Core2 DUO Processor
- Intel DG965WH Motherboard with on Board Video
- 2 x 512MB Corsair Value Select DDR2 667
- CoolerMaster iTower 930 Chassis (Reviewed Here)
- Samsung DVD Writer
- Maxtor 80GB EIDE hard disk drive
- Seagate 300GB SATA hard disk drive
- Seagate 320GB SATA hard disk drive
- HP CD-Writer 9200 SCSI External Drive
- LSI Logic 53C810 SCSI Card
Our operating system of choice was Windows XP Pro with all the latest service packs applied.
Performance
To test the performance of the Zalman ZM360B-APS power supply, an idle environment and loaded environment were established. The idle environment was established by allowing the computer to sit powered on for a minimum of 30 minutes after initial logon into the Windows XP desktop. To load the computer we ran Symantec 360, Futuremark Corporation 3Dmark06, and Passmark Software’s BurninTest 3.5. We also did a disc copy from two optical drives and played music through media player from the hard drive.
The voltage readings were taken by using a digital volt meter taken under idle and loaded environment. A sound meter was also used to measure the noise level coming from the rear of the computer at a distance of 6 inches away. With all these programs running, how did the Zalman ZM360B-APS stand up and how loud did the power supply get when loaded? Let’s find out!

The Zalman ZM360B-APS power supply actually performed very well. With a voltage dropping between .02V and .04V, it shows that the power supply is accurate and is within the manufacturer specifications. The Zalman power supply performed very well and shows that Zalman did not make a cheap basic power supply that just happened to look good.

The Zalman ZM360B-APS power supply is also very quiet. The readings were taken 6 inches away from the back ventilation area of the power supply. When loaded, the noise level only increased by 2.5dBA and the noise produced was not annoying by any means. The majority of the noise generated likely came from the programs accessing the hard drive and the CPU fan increasing speed to meet demands. None of the noise seemed to actually be coming from the power
The large fan in the power supply did not seem to be moving very much. A visual check of the fan showed that it did not speed up or slow down during the test. I was expecting that the fan would speed up to deal with the increases heat and demands, but instead, it barely looked like it was moving at all.
Final Thoughts
The Zalman ZM360B-APS is an attractive power supply despite its small power rating. It is a good choice for anyone looking to replace their original equipment power supply and has a great deal of flexibility for future expansion. The polished and finished look of the metal is one of the great features in this power supply and gives it a very performance oriented look.
The added value of having all the extra power connectors makes the Zalman ZM360B-APS such a great purchase. The two video card power connectors allow anyone to add an extra video card or two into their computer without upgrading to a higher wattage power supply, within reason. The most high end cards will still require a bit more juice at full load.
The stable performance under load, sleeved cabling, extra assortment of power connectors and the attention to detail on the finish of the power supply is why the Zalman ZM360B-APS power supply gets a rating of 9.0 out 10 and a full recomendation by me.

- Sleeved cables
- Detailed finish on power supply metal case
- Extra video card power connectors
- Seeing that Velcro ties come in the box
- Good instructions manual
Cons
- Packaging downplays what’s inside the box
- Velcro ties a bit too short
Overall Rating: 9.0/10.0
