>o 520w uzteks?

http://www.techpowerup.com/reviews/AMD/HD_7850_HD_7870/24.html
Orientuokis, kad tavo videlka es kazkur ~100W-220W (tos kur eda daugiau W kaina didele)
CPU - SB estu 95W, Ivy - ~77W zada..  visa tai is +12V.. poreikis ~180W-300W ant CPU/GPU..
HDD, MB, DVD, FANs ir t.t. na grubiai koki 50W pridek ir pakaks.. 
Jei imsi HD6850'uke + IB i5 - ~200W + ~50W -- kokie 250W.. tai ar pakaks 520W?

Both PSUs are very quiet at loads up to 200 watts, especially the 520W model. 
Alas, the fans accelerate quickly at higher loads, making both PSUs noisy at 300 watts.
