I'm about to buy a pc with the following components:

Intel Core 2 Duo E7500 Processor 3.0GHz 1066FSB 3Mb
Transcend 2Gb DDR2 800 PC6400
Gigabyte GA-P43-ES3G Intel P43 + ICH10 Socket 775
Sparkle GeForce 9500GT 1GB GDDR2 Passive HDMI PCI-E Model SP95T1PD2H
Compucase 6C60 Black Midi Tower True 300Watt PSU
Samsung Spinpoint F3 1TB 7,200RPM HD103SJ
Samsung DVD-RW SH-S223F x22 SATA Black OEM

Will the 300W PSU suffuce or should I raise is? Please take into consideration future upgrades of various devices.

Hello, welcome to OCF! :welcome:

I'd recommend at minimum a 400-450W PSU. Corsair makes two solid units in that range. What do you have planned for future upgrades? If you want future-proof against a rather high-end GPU, I'd get at least 500-550W, if not 650W. New GPUs are becoming quite power hungry and it's always better to have more than you need than have your system crashing because you tried to cut it close. I'm partial to Corsair PSUs and have three of them, two VX450s and one TX650 for my main system. They're very solid units that get the job done without complaining. If you want other options, have a look at the recommended PSU sticky. One last tidbit - IMHO, high-amp single-rail PSUs are the way to go.
