Also, is your motherboard PCI-E2.0 or 1.0? The info I need on your PSU is the amperage on the 12-volt rail, and what brand it is. If it's Corsair, you're fine. Related resources HEY!

Your PC may boot up fine initially. But once your system is under load, you may experience random system crashes or reboots. stoleto November 3, 2009 5:45:29 PM Thanks for the wonderful answers. I will buy another Mother Board (GIGABYTE P31-S3G - probably (for the nice price that it has ) ). So, i have another question now. If i do not change the 400W Power Supply, is the system crashes/reboot expected while everything else is in order? stoleto November 3, 2009 6:12:42 PM BTW, the power Supply is: FORTRON BLUESTORM II 400, 400W stoleto November 7, 2009 9:55:13 AM Just to let you know, it works perfectly, for now, on 400W PS.
