HP 585008-001 Power Supply.
Replacement upgrade 500 Watt power supply for HP Pavilion Desktop PC.
The replacement power supply delivers more power than the original. It's a feature that will benefit, not harm your system performance.
Also benefits you and enables you to support more add-on peripherals like Hard Drives, Video Cards, Digital Cameras, CD RW, DVD-RW etc.
Question: DOES THIS HIGHER WATTAGE UPGRADE MEAN A HIGHER ELECTRIC BILL? Would it hurt my PC which may or may not need that much power ?
Answer: This power supply delivers power On-Demand. That means it only delivers the power that's needed by the system, nothing more. If your PC now needs 400-Watt power because you added more components to your PC, it will use only 400-Watt. If your PC currently uses and needs only a 300-Watt power supply, it will use only 300-watt and operate leisurely.
