   This is a high quality power supply. Everything about it is top notch. Just about every power cable you could think of is included to connect it to your motherboard, graphics cards, and drives, etc. I installed it in a new build without any problems. I did have to buy an additional extenstion cable for the motherboard power as I mounted the power supply at the bottom of an ATX case and the motherboard power connector was near the very top of the case. Delivered very quickly. I would buy this product and brand again without hesitation.

   I bought this because my mining rig needed little more power to run 4 gpus. I had a 650w made by topower and when the wattage would rise above 670, the computer would shut down. I installed this psu and the exact same rig is now drawing 530w with this psu. This thing is far more efficient than my last psu and will save me a ton of money in the long run.

   I’ve been building computers since the 80’s. One thing that has always aggravated me about desktops has been the noise. I’ve overclocked for years, and thus have had to deal with a bit more fan noise to cool my CPUs, case and PSU. This is my first Seasonic power supply. First things first, it was packaged well in a cardboard box, but on opening it the PSU and cables came in a sewn cloth case, looked like velvet. Packaging does not make a good product, so I installed the Seasonic in a i7 build with 2 ssds, 3 HHDs 2 opticals, a GTX 660 with 2 fans. I can hardly hear it running. It’s quieter than my laptop. It’s only been running for a few days so I can’t make any reviews for longevity, but for quiet operation it’s the quietest PSU I’ve ever used, and certainly the build quality is the best of anything I’ve seen in all the years I’ve been building! Good job Seasonic! it’s great to see a company take pride in their products!
