+monitor,burner etc.
How much wattage I'm going to need for the psu and the ups?

For PSU you can get away with a 300W-450W, that CPU & GPU don't use much power at all.

A 500 watt power supply would work completely fine just make sure you get a good brand and in my opinion atleast an 80+ silver. Look up psu calculators on Google and you can do it yourself.

Assuming you have no significant graphics card upgrade plans, I'd get a 360W Seasonic "G" series or a 380W Antec Earthwatts and call it a day. For the UPS, I use and recommend the Cyberpower APFC-series, for having a waveform much closer to a true-sine than most cheap UPS units. The smallest one they offer is 510W for $119: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Does a ups need the same amount of wattage output off the psu?

The UPS needs to be able to provide the total power needed by all the devices attached to it (e.g. PC, monitor, speakers, any external devices). Exceeding that amount increases the run time. Under normal conditions of occasional use for minutes at a time, a typical UPS battery will last 4-6 years, after which they are user-replaceable. Under a gaming load, your PC will probably not pull more than 150W from its UPS.

I thought a 450w psu with a 350w ups..

Those would probably work, although most cheap 350W UPS units use stepped square waves that put more stress on attached components than a true sine wave does. It isn't common, but some PSUs will not run at all on stepped square waves (I understand because they "linger" too long at 0V, rather than crossing cleanly like a sine wave does). I have one such PSU myself (an Antec SG-650) that will run just fine on one of the Cyberpower units.

Can my whole processing system consume 300w?

If you overclock it, add in a few drives and fans, then run benchmark programs for maximum possible load on all parts, you might manage to just hit 300W. Realistically, a gaming load would be unlikely to need more than half that (plus the monitor). My "Gypsy" build (in my .sig), while running GW1, with its monitor, pulls around 120W from its UPS. Your proposed CPU may use a little more, and your graphics card uses a little less.
