Power Supply Voltage Variation

Is 10% variation in voltage output of PC power supply normal? This applies to all terminals (12V,5V, 3.3V)

Your info is very much appreciated.

It only has logo like an I. model is LC-B300ATX.

variations: 12.9V to 13V
4.5V to 5.2V
3.1V to 3.3V

10% voltage variation is just too much for system components to bear on a long-term basis.

for instance, hard disk cannot function normally if +5V rail drops below 4.8V OR could malfunction if it swings above 5.4V, etc.

then maybe i should load my gun. bring that power supply still with warranty, return it to the computer shop where i bought it. then shoot the sales person and the technical guy!!!
