Zalman Wattbit II ZM500-XEII
 | Outdated Product Affordable 500W mid-range computer power supply with traditional fixed cable subsystem and non-80 Plus certified. The manufacturer is positioning itself as a product of an affordable price category, designed to power universal home and low-cost gaming systems. It can be used as a regular power supply for workstations (including those equipped with professional graphics accelerators of entry/middle level). Cooled by a controlled low-noise 120mm fan with an optimized impeller shape for better heat dissipation. The Zalman ZM500-XEII power supply is based on a simple and reliable hardware platform with traditional circuitry using the principle of group voltage stabilization. The use of a high-quality element base and fairly large aluminium heatsinks allow the device to deliver up to 90% of the...power along the +12V line, operating with a current load of up to 37.5 A. The set of cables is notable for four SATA connectors, three MOLEX, and a PCIe 8-pin connector (6+2). The manufacturer provides a complete set of necessary protective systems, including: SCP (short circuit protection), OVP (overvoltage protection at the input), OPP / OLP (current overload), OTP (overheating). |

Pros
Cons
Due to the mine boom, I decided to take a video card from the used market. And powerful video cards of previous years require 8 pins, 6+6 pins, etc. Consequently, that’s why I thought about a new power supply, so that there would definitely be no problems with power supply later. Among state employees I looked at Fsp, Zalman, Chieftek was already more expensive. Stopped at Zalman. In my case, it's quiet. There was some rustling for the first couple of days, but I couldn't determine the cause, whether it was the PSU or something else. A large number of pins. There's an 8-pin for the processor, and 2x6+2 pin for the video card, more than enough. Outputs almost the full 500 watts at 12V. According to online reviews, it has some system protections against failure (I'm not familiar with the details). A very barely audible whistle comes out. My system is very quiet and you can only hear it if you listen closely. Again, I’m not sure that this is exactly a power supply, but as for me, there’s nothing else. It’s not critical, as I already said, it’s not audible during normal use. Maybe even a marriage. |
An excellent power supply for undemanding systems. For assembly into a Mini-ITX case, it was perfect. Since the assembly is cold, this unit is not very noisy - 200 watts in games. You can hear it, but mostly at night. It's not noticeable with headphones or during daytime noise levels. Zalman, although it's not as good as it used to be Without LGBT lighting No obvious drawbacks  Igor Saunin: use Zalman ZM400-XEII less than month |
