I want to replace the graphics card and power supply as they are both heating up a lot and its causing issues with my graphics in game (lots of bright colours). It is a small form factor Lenovo Thinkcentre so I dont know if all graphics cards and power supplies will fit, but I am not sure.

Looking for recommendations for what exactly I should do. Cost for both preferably under $300.

Thanks.

Hello back,

Okay, you have a bit of an issue with your PSU. The bright colours (yes, spelling) you see could be a function of the PSU not providing enough power for the system.

I have tried to track down what model of Lenovo Thinkcentre SFF you have, it appears that it is the M82. But I cannot find anywhere that states that this system would come with an i5-4430 so I ask if you have upgraded any parts on this build? I have tried to determine your mobo part number but I am just not sure. If you want to proceed you will have to run this program, it is free and safe,

When you run it will extract information on your CPU (CPU/Caches), mobo (Mainboard), memory timings (Memory), installed RAM...

There is no way that a 240W PSU will be enough for an upgrade but like a lot of IBM/HP builds it is a non-standard size so ordering a replacement is going to be a challenge. First issue is that the mobo appears to have a 14-pin power connector which is non-standard.

You can get 24-pin to 14-pin adapters (am I right on the country?)

But truthfully I would be looking at a new mobo if possible. But before we proceed we need the exact info from CPU-Z.
