  1. lol oh well? What would happen if i am overdoing it?
  2. Random system reboots when your rig is peaking its performance (when it uses most power and is effectively squeezing all the juice out of the PSU).

    I have never heard of anything catastrophic happening due to low voltage. The device just stops performing a task it was performing, and your platform, detecting this as a serious error (paranoid as it is), reboots your machine to save your hardware.

    I am, however, using a 325W PSU for a computer that really requires 337W... it does reboot occationally. Since you deviate more than I do (you lack 19W), and particularly if your PSU is a cheap one that is usually shipped with pre-built computers, then I definitely recommend that you buy a better PSU.
  3. u'll be fine. if ur not rebooting then dont worry about it. Dont fix something that doesnt need fixing
  4. Exactly what I thought pengwin although i have a 450w coolermaster i just cant be bothered changing it
  5. The one i am using is called besttec or bestec it came with my compaq. Is coolermaster better?

    Should i expect less noise and less heat?
