liberty 500w should be able to run your pc w/o problem.

anyway... silverstone 560w (cheaper price) also should run your pc w/o problem.

well silverstone 560w is good too. many ppl using it. either brand of enermax, gigabyte, silverstone do good job..just the pricing (value) problem and.. of course electronic thing sure will have some faulty just depends on your luck, even you buy the best brand among all.

since it wrote 384w(32A), then according to the label, it should provide max 32A on +12v rail, which means it provide more than enough for your current pc, you can use it w/o worrying.

normally you can't use 16A + 16A, but you need to take the total wattage. in this case, it show 384w / 12 = 32A. but let say others psu may wrote 16A + 16A but with total wattage of 300W, which means 300 / 12 = 25A. which is maybe a bit under power for your pc.

more powerful the better ma

Odin GT got software can monitor those wattage but pro don't have.

as i explain b4, take consideration on total wattage then divided by 12, you get the total amperage. and yeah, gigabyte odin gt 550w can power up your pc.
