Rosewill Capstone 750W Power Supply Review

Testing results (Regulation & Ripple)

The
electrical performance of the Rosewill Capstone 750W power supply might not
have been the best we have ever seen but it certainly was much better than what
most technology adepts would expect from a product with this kind of price tag. All of the
voltage lines are regulated within 2.2% between minimal and maximum load, while
the maximum recorded voltage ripple on the 12V line was only 42mV, a mere third
of the 120mV design limit.
