4890 psu question

[finalcloud]

I'm a little confused as to whether a 4890 would be ok with this psu

Using this calculator:

I only get 333w peak load and that's with 10% capacitor aging (thought I'd add it to be safe)

Can anyone clear this up for me?

Is what I'm looking at getting, I'd just rather have a 4890 instead of that 5770.
