The system I am installing the Toughpower QFan 650 into consists of the following:

Cooler Master Cosmos S Full Tower Case
Biostar TForce 570 SLI Motherboard
AMD A64 X2 6400+ @ 3.4Ghz 1.5v
Thermaltake MaxOrb CPU Cooler
XFX 8800GT @ 750/1050 1.1v
3 x 74Gb WD Raptor Drives
16x DVDRW, Floppy Drives
SoundBlaster Live! Card
6 Fans, 4 USB Devices

Strangely the user manual makes no mention of the rubber sleeve that is included with the QFan 650 and neither does the product page on Thermaltake's website. I assume this device is intended to reduce any vibration caused by the power supply and thus prevent it from causing chassis noise. It is easily stretched to fit over the end where it mounts to the case. It is interesting to note that the sleeve appears to be cut to fit an older style power supply with an 80mm exhaust fan in the rear panel. But because the power supply mounting configuration hasn't changed over the years, the screw holes line up exactly where they need to be.

Unfortunately the case I am installing the QFan 650 is not made with the idea of an extra mm or two of clearance around the mounting end. It is positioned at the bottom of the case rather than the more traditional top location, although we are seeing more and more case manufacturers beginning to adopt this layout. One of the mounting holes is slotted top to bottom and this is the only one that lines up. The rest are slotted side to side and with the sleeve in place, the power supply is positioned a bit too high to get a screw started. I could have enlarged the holes in the case with a drill but elected to try removing the sleeve first, at which point the remaining holes were now where they should be.

Another potential problem with locating the power supply at the bottom of the case is that most motherboard connections are traditionally located towards the top. The main ATX and secondary +12v power cables might be a little on the short side then. Luckily the case manufacturer has included extension cables to use for just such a purpose, yielding enough length then in order to route the cables around other components such as the CPU cooler and video card. All the remaining cables had plenty of length and I did not have any problems reaching the other devices in the system. I used the 8-pin to 6-pin PCIe adapter as I only need one of these connections for my video card and I figured I might as well use the one that is hard wired from the power supply.

Let's wrap up this review with testing and final conclusion.
