Compact 1U computer power supply designed for tight installations. A 40MM low-noise fan uses an intelligent, temperature-controlled speed curve to balance cooling and stable performance while minimizing audible noise. Available ratings: 250W, 300W, 400W, 500W, 600W, 700W and 850W. Important: the 250W, 300W and 400W modules do not support 110V input. The 500W, 600W, 700W and 850W modules support 110V. Attention: this packaging does not include a power plug. 1U form factor makes it easy to install and arrange in space-constrained environments.
