Pros
Cons
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 |
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. |
