I would like to upgrade the graphics card in my PC (this one ), but first need to upgrade its measly 225w PSU. As you can tell from the specs page, the PSU must be small (Micro ATX I think). It should also be fairly inexpensive, and anything between 300 and 400w is fine. Help is much appreciated!

Your power supply unit is a proprietary design. The notch below the AC receptacle is where part of the motherboard sits.

Is there anything that would fit in the same space? (without the notch) The space is roughly 110x 110x 85mm (ldh)

I assumed that the OP had the Desktop Form Factor version of the ThinkCentre M55 based on the link the OP provided. Please excuse me if my assumption is wrong.

There is also a tower version and an ultra slim form factor model.

Maybe the OP should post the exact model number or form factor of the system they have.

I Googled on ThinkCentre M55 power supplies and found images of the internals of the desktop unit and its power supply.

I haven't been able to find a power supply with those dimensions.

Another thing that needs to be taken into consideration is that the proprietary PSU is actually being used to cool the desktop case by exhausting the warm air from inside the case. That is why there are many intake vent holes on the side of the PSU with the DC output cables and an exhaust fan on the exterior face of the PSU.

About the only thing you can upgrade on this unit is the memory or the hard drive, truly proprietary. Start saving for a new build!

How about an external psu, like this:

It'll work but you'll have to do some case modding to mount the adapter plate.

If that's the route you choose then you might as well remove the original PSU and replace it with a 80 cm case fan to cool the case.

Where do you intend on finding one?

On another note, what if I bought a normal size psu, mounted it outside the case and used an add2psu or similar?

You could do that, though you'll have some noobs crying about the dangers of having a psu outside of the case.

Bite the bullet my man, Time to build a new PC.. By the time you spend time and money rigging something up you could have just bought a few new parts and moved into a new case.

Looks like you can save your DVD drive and Hard drive from your old build. (both are Sata)
