Quiet PC USA is a supplier of high quality computer hardware with an emphasis on low noise operation that has been sponsoring reviews at Bigbruin.com since we first got going 5 years ago. From cases to coolers, and accessories of all kinds, they always have something new and interesting to check out. This time around they have sent over a power supply that incorporates a few interesting features, and of course near silent operation, that make it worthy of being stocked at a place called Quiet PC.
The power supply in question is the Nesteq EECS 700 Watt ultra quiet power supply (model ECS-7001), and it is shown in the promotional image below.
Prior to this review, I have to admit that I was unfamiliar with Nesteq. Visiting their website reveals that they are a fairly young German company that describes itself as having a "focus on high-end industrial design and hi-performance power supply manufacturing". Their current product line up is rather small, with a handful of power supplies and a few hard drive related accessories. The 700W unit provided for review is from their EECS (Enhanced Easy Connecting System) series which offers extremely low noise operation in addition to desirable features like a modular design, 80 Plus efficiency, and four 6+2 pin PCI Express connectors.
Before taking a look at the Nesteq EECS 700 Watt ultra quiet power supply and its unique approach to modular cabling, let's take a look at some of the published data on it, as taken from the product page on the Quiet PC USA website.

All of the basics are provided above, and one thing that caught my eye was that each of the four 12V rails is rated for just 16A. This should be enough for most users, but some high end components may draw up to 20A (or more), which could result in over-current shutdowns. There are four 6+2 pin PCI Express graphics card connections, but users should not consider that as an indication of SLI or Crossfire certification. While you can physically connect multiple graphics cards, whether they will work well is another question that I hope to resolve in this review.
