I am currently working on my masters in computer engineering from a highly ranked engineering school (Maseeh College of Engineering & Computer Science). I have taken some graduate level power design classes, and we are thought to follow manufacture specifications. Most transistor manufactures recommend less than 70% utilization for long component life. Granted, the regulation work I have done is nowhere close to the amperage of aforementioned computer power supplies. I personally believe it/s common sense not to purchase components that will be operating at 100% utilization.

These power supplies are rated for continuous output, and warrantied so... most of the high ends come with massive power reserves and thus are underrated, for efficiency and electrical performance reasons... you're nowhere near the actual rating limit of the components used when buying a good power supply and keeping it inside specifications(that means 100% load too) wink.gif

I simply disagree. Your suggestion is a good one, but in my opinion, the Capstone is worth the extra money.

I read a while ago that its a good idea to stay below 70% of the PSU rating. Most of you guys are suggesting I 100%?

As stated above, a quality PSU can safely output 100% of its rated capacity for years. You needn't buy a larger PSU than is necessary for your system just to keep it running solidly over time. You just need to buy a good quality unit and you'll be fine. For further discussion of this, please look here: http://www.overclock.net/power-supplies/872013-50-load-myth.html

ya, the capstones have great performance, great price and are very quiet under load. only real drawback is the fixed cabling system :C

Then if were gonna spend an extra 30 bucks for no reason. http://www.newegg.com/Product/Product.aspx?Item=N82E16817182132 plus its modular and more power.
