I have  HP PRO 3000 SFF desktop PC and I need to get a cheap graphics card just to play MineCraft.

Unfortunately I've looked on trademe but the specs of these cards require a minimum of 300 watts power supply. Unfortunately I only have 250 watts Power in the PC and it's a custom physical size so It can't be replaced.

Here is a list of known working cards:

 

•  

  ATI Radeon HD 4350 (512MB) FH PCIe x16 Card

   

•  

  ATI Radeon HD 4550 (256MB) DH PCIe x16 Graphics Card

   

•  

  NVIDIA GeForce GT230 1.5GB PCIe x16 Card

   

•  

  NVIDIA GeForce G210 512MB LP PCIe x16

   

What are my other options in the form of graphics card.

Thanks
