Review: Good mid priced power supply - This power supply is working great in my new PC. I had trouble initially getting my hard drives to work. It turns out some hard drives have the Power Disable (PWDIS) feature. This feature allows the host system to perform a hard reset on the drive by manipulating the third pin (P3) of the SATA connector. This power supply doesn't seem to have that PWDIS feature, but you can get around it by using a Molex to SATA power adapter OR adding some kapton tape over the third pin on the drive. I used the tape on my drives and now everything is working great!
Review: Good Quality and Decent Cabling for Modern Systems - Smooth and quiet. Black cabling is nice and allows it to blend into the system better. Would prefer it came with additional SATA support out of the box (without needing adapters) for those of us running optical drives. High quality capacitors are a huge plus.
