Changing the power supply of Acer Aspire X1800?

[RickyT]

I just got my Aspire X1800 and after I opened it, I was surprised that the size of the power supply is not the usual one. It's smaller compared to the PSU of my other desktops.

I'm planning to upgrade it to a higher wattage, because I'm planning to install a video card in this system.
Is there any particular brand or PSU type that I should buy?
I'm also thinking about changing the casing of the CPU to a bigger one, but that will be my last resort.

Try the Sapphire HD 5450 1Gb DDR3 video card it only has a 25 watt max draw it should work for you and still fit in the origanal case aswell as you wont have to buy a bigger supply
