I have opened up my tower and looked at the power supply case and all the numbers on it. I am very lost.
I want to install a second graphics card into my machine so that I can connect a second monitor to it (the onboard graphics card only has 1 VGA/DVI port), but when I try to install it, my power supply can't handle it (computer won't boot up).
What do I need to consider when getting a new power supply, and where can I find out this information? I have downloaded a piece of software called CPU-Z and that provides me with a lot of information about my computer.
1To get the best answer, add in the make/model of the motherboard and graphics card or the make/model of the PC to your original post. Manufacturer's often include power requirement calculators on their websites so knowing make/model is very helpful. – Tog – 2011-11-03T07:45:41.967
As a side note, don't skimp on PSUs. Always stick to well-known brands (Antec, Corsair, and Seasonic, to name a few). It's not only the name you're paying for, but the quality and the support. – happy_soil – 2011-11-03T12:09:19.260
Motherboard: ASUSTeK Computer INC. Model: M3A78-CM Current Graphics: ATI Radeon 3100 Graphics Card I want to install alongside: ATI Radeon X1300
Thanks for suggesting me those calculators guys, but I've checked those out earlier and they have like 50 options for which I don't even know what to put. I'm not even sure what's the number I'm trying to get out of them. By what aspect do I rate power supplies anyway? And thanks, all your help is appreciated :)! – ExitFailure – 2011-11-04T02:35:10.143
