Load regulation is within 1%, so tight enough, on all major rails.

A glance at the light loads table is always useful, as the PSU will typically operate at light loads.

As far as i’m aware the 850W version is based on a different platform. Does it hold up to the 1050W/1200W versions or should i avoid it?
Slightly diff platform but still scored an “A-” rating, very good PSU, I have one in my build.
Thanks for a review crmaris. Will you be doing a review of PCCooler YS1000?
I think I have them too somewhere 🙂
