Coolmax has an almost-legendary reputation for innovative and efficient cooling designs. The CA-400 400W Power Supply has a highly-efficient design that reduces power consumption, and a single 80 mm, silent fan provides efficient cooling augmented by sleeved cables reducing clutter. Also, the high-quality fan guard and connectors feature a high-conduction coating completing the thermal control package. Industrial-grade protection circuitry ensures protection from power and voltage surges. One main connector (20 + 4 pin), one 12V (P4), one SATA, one Floppy, and four peripheral connectors are more than enough for all your components. The COOLMAX CAA-400’s universal connector fits most branded motherboards, and it fully supports all Intel and AMD offerings. Coolmax has a great reputation for cooling solutions and reliable power, and this one’s pretty chill. Pick it up for only a minor amount of cold cash today at Newegg.com!
