12V: 11.95V idle and 11.75V stressed. Not great, but not bad either.
5V: 4.97V stable.

my 550W antec's 12v line always stays around 11.80V; idle, stressed, high or low v-core, no difference

mine 300w zalman iz always 12.20 - 11.92 i think...hmm what,?

i cannot even boot with a 300 watt due to all the maount of power leeched by my hardware (especially the pelt)

I have dual PSU
works fine, maybe an idea ?

but everything works aok with my 520 watt superflower, and there ain't no place in my case for anything
I'm just looking for a flashy psu to put into a future fun-case

Enermax 600+W should suit your needs.

Enermax is known to sport low 5v rails

my enermax 350W gives me an average of 4.94V on the 5V rail ... not too shabby, considering what it's feeding

dunno, but I'll stick with my sf-520, considering I see that every single unit can differ a bit, as with all hardware...the rails aren't that bad...
but I'd like a shiny one to put into my future windowcase
