Answer» i have and old 1.2 ghz i have 2 different psu's it can run both atx one is 160w and the other is 350 but the 350's -12v rail runs at 11.6v which one should i use?160 w is for lightbulbs.

Answer»

i have and old 1.2 ghz
i have 2 different psu's it can run
both atx
one is 160w
and the other is 350 but the 350's -12v rail runs at 11.6v

which one should i use?160 w is for lightbulbs.

Use the other for now. Have you tried it?i have tryed them both(160 came in it)
i was just wondering if the -11.6v rail is to wory about?i also found a site that trys to predict power consumptions
http://www.jscustompcs.com/power_supply/

it sez i need about 217w

but the computer came with a 160
meaning that psu is running at allmost full burn
wont it burn out soon

which is beeter an unser powered power SUPLY or a good psu that has a bad rail (some one told me that rail is for serial is it true?)Big is best.kingneo......

WARNING : Computer Ebonics

USER IGNORED!a rail is the type of power
so a psu has a
+12v rail
-12v rail
3.3v rail
5v rail

acording to the bios the running voltages are
160w
vcore = 1.4
+3.3 = 3.2
5v = 5
+12 = 12.5-12.6
-12 = 12.3-12.4

350w
vcore = 1.4
+3.3 = 3.2
5v = 5
+12 = 12.5-12.6
-12 = 11.7-11.6

If system performance is not a priority, you can try the 350 watt.

To get an exact measurement of the voltages, use a Multimeter.so the 160 will burn out sooner
and the 350 will make the computer run slower?

You need more power the more components are added that use that power - a second hard drive, a high end graphics card, 2 CD drives, etc. It may not fuinction with the 160, especially if it is failing, the 350 provides more power if you need it (and ASSUMING it is a good component.)
