You won't be disappointed with this P/S. It has all the connections you need and more. I have a modified workstation built into a desk and the modular design makes it easy to remove my pc from my desk, leaving behind the P/S. This makes cleaning my system a breeze. Before I had a P/S that wasnt modular and I had to disconnect everything to remove my workstation from the desk. It is hard on the motherboard and all the hardware as well. With this P/S, all you have to do is disconnect everything at the P/S and within a minute have the PC out for maintenance or hardware changes. The fan is big but super quiet and it adjusts the speed automatically when needed. I havent heard it running since I fired it up though. The cables are top quality and the velcro straps on each cable make cable management a breeze. I didnt spring for the 1600W version due to the length of it and also I dont have a power outlet to support it. If you need the extra power and you have a unique case set up, I would recommend this P/S. You wont regret it.

Musical Fidelity V-DAC Upsampling Digital to Analog Audio Converter Review

I've had the Musical Fidelity V-DAC for just over a week now and put it through it's paces with a variety of rock, pop, jazz and classical music. The V-DAC definitely sounds quite a bit better than my Oppo DVD-980H's analog outputs or the Oppo connected via coaxial digital to my Onkyo TX-SR705. The difference is immediate: much deeper bass, wider and deeper "sound stage", instruments are clearly differentiated whereas before they sounded mixed up, much better tonal differences with voices, stringed instruments, even electronic music. I didn't find the Onkyo or Oppo thin sounding at all (quite the opposite), but the V-DAC sounds significantly richer and more "solid". For the money, I really couldn't be happier - it's a great little device. I also compared the V-DAC to the DAC built into my Marantz SR5300 A/V receiver and again, the V-DAC comes out on top.
** WARNING ** Don't try the following yourself unless you're comfortable experimenting with and modifying electronic components! **
One "tweak" I couldn't resist was to replace the wall mart power supply it comes with with a larger regulated power supply. The one I got came from Amazon at a very low price and I recommend it too: Pyramid PS3 3-Amp 13.8-Volt Power Supply. Changing the power supply does improve sound quality further - most noticeable as deeper and tighter bass, more "solid" images, and stronger dynamics. All of these attributes were already strong points even with the stock power supply. The V-DAC does run cooler too using the bigger power supply, so hopefully that will extend its life.
Even without the above "tweak", the V-DAC sounds just great, and should provide a noticeable improvement for folks who do not already own a high-end DAC or A/V receiver. I hope you have as much fun with the V-DAC.
