Replace power supply

I have a damaged power supply that I need to replace for my Pentium 3 PC. It it 250 watts and 230 volts. i cannot find any replacement part for it. Will a 400 watts power supply work on it even some of the specs of the 250 watts is different.

For 250 Watts
AC~           Voltage             Current             Frequency
Input            220V~                4A                  50-60 Hz

DC          +3.3V  +5V +12V  -5V   -12V  +5VSB
Output     11A    18A  8.5A   0.5A  0.5A  1.5A

For 400 Watts
AC Input  220V 50/60Hz  8/4A
DC           +3.3V  +5V  +12V  -5V   -12V  +5VSB
Output     14A     25A     12A   0.5A  0.5A  2.5A

Wiil the 400 watts power supply work on my pc?
