Corsair CS450M Power Supply Review

Testing results (Regulation & Ripple)

The electrical performance of the CS450M is very good, especially considering that this is a power supply designed for system builders and mainstream users. Voltage regulation is at about 2% for all of the voltage lines between 20% and 100% load. Ripple suppression is very good, with the maximum ripple being 46 mV on the 12 V line while the power supply was operating at maximum capacity, which is a figure that even top-performance designs sometimes fail to achieve.

    Got this PSU for $29 (using bitcoins to buy it), at tiger-direct. Makes a great single-card setup with any CPU and most GPU’s with a single SSD for the hard-drive. Keeps the PSU at the 50%-75% range, where it is most efficient, when gaming.

    Anyone else find it strange that the power supplies are priced in tiny $10 increments? The 750W seems fine but the rest seem overpriced by comparison.
