Jun 23, May 12, Question PC buzzing sound crash. Apr 13, Dec 23, Most PSUs specify the maximum number of watts they output, usually between watts and watts. To figure out how many watts you need to power your computer, you should itemize the components with their individual power demands and sum them to arrive at a total.

You can use the estimates provided in the next section or an online calculator such as the PSU Wattage Calculator from Thermaltake that provides a detailed questionnaire, including how you plan to overclock your computer, to help you arrive at a the total wattage required. As a general rule of thumb, an AGP video card uses between 30 and 50 watts of power. A PCI Express video card uses 50 to watts, or it might use to watts if it has an additional power connector on the card.

Regular PCI cards consume between five and 10 watts. Your motherboard probably uses 50 to watts, and each stick of memory requires about 15 watts. The processor needs between 80 and watts of power.

Purchasing a power supply that provides exactly or close to the power you need today is probably not enough. I pulled out an old HDD from and it consumed only 13 watts when just spinning. Because of this, HDD vendors are stepping up their energy conservation efforts. In this regard, Western Digital -- one of the leading drive makers -- is moving to a new product line called GreenPower. This would raise the bar for power efficiency on desktop drives. I expect SCSI drives will eventually be on that same power curve as well.

Save Power: Hibernate All of this means that power consumption is rarely the correct primary factor for upgrading HDDs. Secondly, if you do upgrade your HDDs, you'll get a small lift in absolute power savings and an enormous lift in watts per GB.

The best way to save power on your disks, especially on desktops, is to use the built-in power reduction technology in your operating system that puts HDDs into hibernate mode following a given portion of inactivity.

Per vendor specs, this move will do the most to save energy by cutting it roughly in half for the time spent asleep. For more information on power consumption by specific drives, visit digit-life.
