i need to know how to find out what wattage my computer uses so i can put my com specs in sig
Any help anyone??????? :-?
If I read this correctly you are asking how to find the PSU watt rating of the unit in your tower so you can post it.
It should be on a sticker tag on the PSU.
What a PSU pulls in AC power and what the computer pulls in DC, and, what the PSU can deliver are 3 different things. The sticker will show you what the PSU can deliver (theoretically) and what the system needs in power is figured out by adding up the power draw specs for the devices in the system. There is no documentation for a system which will tell you exactly what all the parts in your system need or use.
If you are a trained electronics tech and know how to interrupt the main DC lines to the system (or use field probes), placing a proper scaled amp meter on each one and observing the changes as the system is used, you can figure out exactly what it is pulling from the PSU, otherwise it is an estimate based on components and you typically add at least 25% to those numbers to be sure the unit runs cool and has plenty of overhead power reserve.
As for the amount of AC current a PSU draws, that will vary based on the load the system is under (heavy use or game play) and the type of source (ie; 120VAC, 220VAC, etc), and requires the same process of intrrupting an AC line (or use a field clamp probe) to see what the unit draws in house current under different load situations.
