Which power supply to choose for 7 coolers for cooling equipment?
Hello, help solve my question. I need coolers to cool equipment. I connected 7 coolers to the power supply (12v 800ma, 50Hz), and they barely spin, apparently there is not enough power. What power supply do I need for them to spin at full power? I would be grateful if you wrote to me how many volts should be in the block and how much MA. For example: 12v 1500 ma.
Characteristics of 1 cooler:
- Maximum operating voltage 13.2 V.
- The maximum current is 80 mA.

Hello! And supply 12 Volts to these coolers, the rated current is: 7 * 80 = 560mA. That is, at least you need a 12v 560mA power supply. In theory, your power supply should work fine. Have you connected the cooler in parallel, and not in series? They should spin normally. However, if the power supply is doubtful, it will be so. For verification, you can power them from the 12V bus of the computer power supply. Yellow wire - plus 12V, black - minus. When you connect 1 cooler to an existing PSU - does it rotate normally?
