Re: Help with new pc
Hi. As og said above, it depends which case you have as to which graphics card/power supply you're going to need. I'm going to assume that unless you're going for a cheap graphics card that draws power from the motherboard then you're probably going to need to upgrade your PSU as 300W just isn't enough juice for a gaming machine. As for the graphics card, if you've got the MATX case you can get just about any PCI-E graphics card so long as it will fit in that small case, and the PSU is big enough (anything over 500W should be good), if you've got the SFF (small form factor) case then you'll need a low profile PCI-E graphics card. These are harder to find... so upgrade your PSU to one that's 500W or more powerful and then make sure you get a graphics card that will fit in your case, and you should be good to go... good luck!
