Originally it was 350W and it ran out of power after installing a new video (ASUS GF 7600GT silent) and a new HDD. System shut down when I tried to install additional fan, which whould suck air out of the case.
Now there is a Nexus 500W PSU, which is nough for everithing plus the new fan.
Yesterday I did some stress on the computer, so here is temperatures graph.
CPU: Athlon 64 X2 4200+
Memory: 1GB DDR2 533
Video: ASUS GeForce 7600GT silent
Room temperature: 28C
