What makes you think you require a 400 Watt TFX form factor power supply?

Did you purchase a new graphics card? If you did, what is its make and model?

There is no such thing as a "gforce 5450". Did you mean the AMD Radeon HD 5450?

That video card does not use much power. You should be able to use that video card on a 220w PSU depending on what components you PC has.

A Radeon HD 5450 realistically won't draw more than 15 Watts (more likely only 13 Watts) under 100% GPU load.

If your 220 Watt PSU's +12 Volt rail's current rating of 14 Amps is unable to handle a graphics card with this low of a power consumption then you really do need to trash it.

I ran an Asus 5450 and upgraded to an HD7750 with no problems at all in an acer x3400 220w psu... still using it ;)
