 H81+G3420+2*4GB+500GB_2.5"+DVD su 250W 80plus SFX PSU  
FPU+GPU_(IntelHD_10Exec) load su tuo "apytiksliu" aparatu, kur rodo kiek 
is rozetes ima rode 71W-73W imant kokius 82% PSU efektyvuma - is PSU ede 73*0,82=~60W
AIDA64 rode 100% 3200MHz FPU load + GPU Load - 53,14W / 28,38W / 15,72W

G3420 -> i5-4460 prides tuos 30W-40W
R260X prides tarkim 118W (zaidimuose ko gero tilps i ~100W)

So... 60W+40W+120W=220W reiketu, kad tame PSU jei butu.. ir is esmes ant +12V (220W/12V=~18A).

Padoresnio 400W paprastai uztenka, jei labai jau ten koks nors belekoks, tai gal pridek bent jau toki:

Su tokiais nebandyciau:
