good question, most vc's will be ok with the CEO and a co-founders paying themselves $150k salary. They do not want you to starve and salaries are a component of every companies operating costs. $300k is a bit excessive. VC's love frugality.
So while you won't be rich, you will be able to upgrade from a 7-11 diet to Whole Foods.
Saying $300k is a bit excessive is like saying gas prices are only a bit excessive -- huge understatement. I don't know how plausible a $150k salary is after a Series A, but I can't imagine any good founder paying himself close to that amount.
