5 out of 5 eggs

Pros: Upgraded from a Corsair TX650W, which served me well, but the Modular design of PSUs today is a great improvement for cable management. This is a top of the line PSU. I wasn't going to upgrade my PSU but I couldn't resist the INCREDIBLE discount of nearly 50%. I had bought a Be Quiet! case and CPU cooler so I gladly purchased this product of theirs as well. This PSU will likely last me well over the great 5+ year warranty. If you never plan to crossfire or SLI more than two cards, this PSU will give to plenty of stability to OC.

Cons: None.

5 out of 5 eggs5 star customer service

Pros: I bought this on sale after reading several very positive and detailed reviews of this product. I figured this was a little over-kill for my build but I would have it for a long time and several builds. I found it on sale at Newegg for -$50 off regular price. I would not have made the purchase at the regular price of $239. The build went together easily but not quickly due to extensive case modifications I made to a very old Lian Li case I was using. I loaded the OS and began installing updates when I found I could not get my computer to post. After going through a lot of troubleshooting I discovered I had a faulty power supply.

I sent an Email to BeQuiet! and received an immediate response. I had several specific questions which I got immediately answered with clear concise responses. There was a short supply of these units in the USA at the time but I was shipped the "last unit in the US" even before I was able to mail back the dead unit. I got the replacement and, so far, it has been flawless. For my trouble, I was also sent a 120mm PWM Silent Wings case fan. That almost covered my cost for return shipping of the dead unit. The new unit is installed and working as expected. Thank you to Christoph for excellent service.

Cons: 1st unit died after less than 24 hours of run-time but read full review.

Other Thoughts: I noticed 2 things that were odd about the first unit. First, the 24 pin MB power connector was an extremely tight fit on the MB plug. It required a lot of force and patience to both install and uninstall during troubleshooting. It did fully seat, but it certainly was not normal or even close to a normal fit. This was not due to a problem with the MB because the second power supply and another power supply used for trouble shooting both fit perfectly.
Second, After turning on the original, faulty, power supply I noticed a strong smell coming from the unit. It did not smell like something was burning or even too hot. It was not an alarming smell at all. It just smelled "new". The replacement unit did not have this odor.
This product has had very good reviews and it looks and feels like a quality product. Since this is the first review on Newegg and the customer serve could not have been better, I am giving it 5 stars. If subsequent reviews find more faulty units then maybe it is not deserving of 5 stars. This review is more about the service I received than the product. I would encourage you to read complete product reviews which are much better, more detailed and do not need to be repeated here.
