X51 power supply question

[soilder198]

Hi, I have an x51 mini computer and want to upgrade the video card in it (gt 640 gddr5) to a much better gtx 660 non ti.
To do this, I need a better power supply. Mine is a shitty 240w that wont work. I can buy a 330w specifically designed for the x51 to be used with the gtx 660, but it's 100$ which is a complete rip off. I don't know how to upgrade the power supply and I dont even know what psu to buy, so I need some help. Thanks

No idea what PSU form factor those guys use. Maybe it says it on the PSU itself.


EDIT: My initial inquiries suggest that the PSU is proprietary. That is not good news. If true, you will need to buy a PSU from the manufacturer.

Google is a god. Found a review of the x51 which shows the custom power BRICK. You're screwed as it's custom designed for the x51.

Alright I guess I need to buy the 330w then. Not at a huge setback but it definitely limits my choice of video cards in the future. Thanks a bunch though.

The review doesn't appear to say its a custom power brick. Its still possible it uses some sort of small form PSU. It might still be some sort of standard you whereby you can get a more powerful unit. I wouldn't count on it though.
