I'm very new to this whole world of computers so bear with me here.
I'm having a problem with my new graphics card being too big for my computer. Yes, it has the PCI Express slot. However, the card wouldn't fit. The guy at the store said that I would have to settle for a less powerful graphics card because of this.
Here's some links:
Yeap. This graphics card will never fit into this case. And even if it could, your power supply would obviously not be able to feed this card's power needs. With just 300W of power you can't do much. I would definitely recommend upgrading your PSU (probably go for 500W).
I'm guessing looking at the pics of the case he got from MicroCenter that it is physically impossible to put it in that case. My original suggestions stand, with one adjustment. You only have a 300W power supply. You will probably need to go to 450W to drive your GPU properly...
ah, the joy of prebuilt computers... you think you are saving a buck until you find out what corners they cut...
FYI, while I love Microcenter, their power spec PCs are trash worthy of making Compaq look like a quality PC company, never buy one again. They have a tendency to take their open box return products, or bulk miss-orders, and put them in these machines as a way to recover some of the money they would have otherwise lost. Not saying they will not back their warranty or anything, but like the issues you are having, they are simply built at a bare minimum spec, and if you want to upgrade it then you would have been better off building your own in the first place.
So now you are faced with a choice; Move everything to a new case and power supply which will void your warranty? Or get a much smaller GPU that will fit in your case and 300W budget?
If you want to go to a higher gpu performance level, then upgrading case and psu is the only way. Well it is not a hard job unless you know how to do it. If you feel you ain't having it, talk with Micro Center to make the installation for you. Don't forget though that you will probably get charged
