    Old system, new power supply

    My old ThinkCentre M92 had a power supply failure. It's a pretty old PC. Nonetheless, the NZXT power supply fits perfectly and worked right away. Overall, the power supply makes a high-quality impression, apparently has built-in safety/circuit breakers and cannot be heard during normal operation. Cable management is perfect - as I said: also suitable for old PCs - with old/ or strange ATX connections. I still need the Lenovo/ThinkCentre adapter to connect to the mainboard - but that's not because of NZXT, but because of the proprietary design of the Lenovo mainboard. A current board with a new IntelCPU will be purchased soon - the power supply is optimally prepared for it. So everything is perfect. I didn't want to make any compromises with the power supply this time and was rewarded. The slightly higher price pays off. There is not the slightest reason to complain. I can recommend the product without any ifs or buts. Ordered via Alternate.de. Delivery difficulties due to Trump mania. But everything else is okay.
