Is here an alternative to getting a alien PSU?

I'm relitively latest to the insides of computers, but I'm learning by trial and error. Unfourtunately I hold made an error, and it turns out my new computer (a1720n) single has 250 watts avalible. I want to install unusual graphics card that requires a minimum of 450 watts, is there an adapter of some big-hearted I can get? Or do i hold to get a brand new PSU altogether?

Is here an alternative to getting a alien PSU?

Only alternative would be to buy a new PC.



The power supply part (PSU) has a +3.3V, +5V and +12V rail. The new video cards draw power mostly from the +12V guiderail. There is no way a 250W PSU w/ fragile (12 amps or less) could supply the power requirement of new and powerful cards.



Be sure to receive a 450 watt or higher PSU that have STRONG +12V rail, preferably dual rail. Perhaps something like this:

Do not freshly rely on minimum PSU recommendation. You might of late run it HOT at FULL LOAD (esp. the +12V rail) and you would have little or no room for expansion. A bigger PSU runs cooler and last longer.
how many things are you running on your computer? i have it in mind are you running the basic ? close to a cd rom , floppy, and your hard drive? okay that is adjectives then try playing your spectator sport and see if you have any problems. i am playing phantom recon advance warfighter and it said i have to have power source of at lowest possible 350 watts. but i am only putting out tolerate 250 or 300 watts. try it you might be polaying your sooner then you assume.
