My system is underpowered and I need a better PSU. This PSU was recommended to me: http://www.newegg.co...N82E16817371002
I used eXtreme Power Supply Calculator Pro v2.5 and found out an about estimate of what I need. Here are the results: Recommended Wattage: 648 Watts

Recommended Amperage: +3.3V: 9.3 A +5V: 21.9 A +12V: 42.9 A


Recommended UPS rating: 1100 VA

Now the recommended PSU has all of the "Recommended Amperage"s but has about 98 less watts and I can't find anything that says "UPS rating". Should I worry about the Wattage and UPS or am I fine with that recommended PSU. I don't want to spend a lot of money just enough to get everything working smoothly and no sudden failures.

Can anybody help me?

PS: I have not factored in any overclocking so will that affect my numbers that much?

This is better at almost the same price(after rebate).

Or a OCZ at a slightly higher price.

The UPS rating is what is needed if you use a "uninterruptible power supply"( battery backup) unit to protect your computer from power outages or surges.

I guess I will go with that Antec that you recommended. It seems like it has better and more reviews too.
