Upgrade Radeon hd 5450.

[ribongen777]

A few day ago, i decide to upgrade my desktop, Radeon HD 5450, and i am installed ubuntu 12.04 LTS with 3D, it is a great running, but i am a bit worry, but i like to your opinions, and i am not here for gaming on that, and i find it, it is must have a watt 400 power supply, but my desktop is running 240 watt power supply, is it fine with that? or should i got a new 400 watt power supply? i like your answer of opinions. thanks.

You need to have a power supply that meets or exceeds ATI's requirement.

Trying to "sneak by" with less could be catastrophic.

The power supply you have right now isn't even close to being up to the task. Never skimp on your PSU.
