I got this PSU as a gift, and I wish all gifts were like this. It's quiet, good airflow, and obvious why it's a gold.

Fan-off when idle. So far so good. Powers my mITX build with a GTX 1070.

PSU | 11-10-2015 | newegg.com : $69.99 after rebate used credit card rewards to purchase; quiet with the fan never running

Great PSU for a single-GPU build. It's fully modular, which is essential for a small case, and semi-passive, which keeps the noise down during idle/regular usage.

Love the all black sleeved cables, made my build look great.

Originally targeted at its 135mm fan but later I found it even better: this unit works almost always in semi-passive mode and the fan is barely spinning! Even the quietest fan can’t beat no fan. Comes with $20 rebate card as well.

Good power supply with black sleeved cables.

ZERO noice at low load

Not hearable noise at medium load

Sweet spot in terms of wattage for this build, it has a silent 0RPM mode as well and it rarely ever starts spinning the fan. Modularity and 80+ Gold is very nice, as well as the sleeved, black cables. When new this thing has a unpleasant stench of chemicals to it, but after a month of usage it's pretty much gone.
