Every advancement in computer technology -- every new graphics card sound card or CPU means a greater need for power. The Apevia (Aspire) ATX-CW500WP4 500W Power Supply is high on efficiency and reliability with a clean design that helps reduce power consumption while solid construction ensures system stability. It has dual fans that provide quiet powerful cooling while industrial-grade protection circuitry protects against power and voltage surges. A thermal fan speed controller adjusts fan speed while balancing cooling power consumption and noise emission. Independent voltage control loop and industrial grade components allow your fan to provide stable output and protection from power and voltage surges. Two +12V rails (12V1 12V2) will support most of your components under... Less

The Apevia ATX-TL450W power supply is high on efficiency and reliability with a clean design that helps reduce power consumption while solid construction ensures system stability. The 80mm fan runs quietly and dissipates the heat to keep the power supply cool and operating at peak performance. Two +12V rails can support most of your components under any load. It has one main connector (20 + 4 pin) one 12V (4 pin) one SATA one Floppy and three peripheral connectors. This state-of-the-art power supply also features universal input and ATX12V compliance so you can use it in a variety of situations and almost everywhere with confidence.Fans: 1 x 80mm fanMain Connector: 20+4Pin+12V Rails: 2PCI-Express Connector: NoSATA Power Connector: 1Input Voltage: 100 - 240 VInput Frequency Range:...
