PSU Qs

[harry18]

so i got some questions about PSUs that i didnt fully understand in the sticky....

so ive seen a psu with duel rail: 12v 1 @ 14A, and 12v 2 @ 15A, am i right in thinking that this works out to be 29A, which if i understand correctly is sutible for mid range systems?

if the wattage is too high will the pc not work right, or will it just adjust its self to the right requiremnt?

Yea, your rite when u say it works out to 29A, and if the PSU is like a 600watt but your computer only uses 250W, the PSU will only put out 250w(only put out what your computer will use)

You'll be fine

Too Much Power? Too Little? How Many Watts Do I Need??
If you have say a Pentium 166 system and are hooking it up to a [good] 500W powersupply ... while that may be overkill, it's not going to damage the computer or anything. This is because the power supply's rating (that is, the 500W) just means that it can deliver at most a sustained load of 500W (or so) however it will only deliver what is required (i.e., so if the sum total the parts you have only require 200W and you have a 500W powersupply, the PSU will deliver 200W).

On the flip side, not having enough power is a bad thing as you will start to suffer restarts, instability and generally "stuff not working right". For systems featuring videocards requiring power adapters, having a weak power supply may mean the system will not boot up.
