so is this psu in the link good?
You've made a couple posts now to ask the same question. You mention in the other post that you will be using a g620, and you have no plans to upgrade the machine later.
You've received 2 types of responses: 1) That the PSU is plenty adequate for that system, and if you don't plan to upgrade, it will be fine. 2) That if you ever upgrade to a more powerful system, you may want a more powerful PSU.
I don't know what else you're hoping to hear. You have to decide for yourself based on that information.
