PSU Selction

Which psu will be best for an i3 rig with an ati HD 6670 graphics card:
Xigmatek VC-403 vs ANTEC VP450P vs COOLER MASTER EXTREME POWER 460W vs Xigmatek NRP-PC402

And will a psu with Power Factor Correction(PFC) work with a square wave UPS?

    First, I'm not sure I like any of those PSU choices, but if limited to the ones you've listed, the last one (NRP-PC402) is probably the one I would choose. If available, I'd strongly suggest getting a 380W Antec Earthwatts, 400W Antec HCG, or 400W Corsair Builder instead. Seasonic has some ~$40 80+ bronze 300W-350W units that would also be good choices, although they don't have a PCIE power connector, so you'd need to use an adapter if you ever upgrade your GPU.
    Second, maybe. Many will, but some see the incoming waveform as unacceptable and will shut down. My Antec SG-650 is like that, and my wife's Earthwatts may be too. Cyberpower has a couple of units (with "APFC" in their model numbers) that aren't exactly true sine wave, but will work with an Active PFC PSU.
  2. Id Reccomend A 600Watt (Or Better) PSU, Make Sure It Is High Quality With ACTIVE-PFC And 80+ Cert.

    Brands (From Best To Decent); PC Power & Cooling, Corsair, Antec, Thermaltake (I Have This 750Watt) Etc.

    Im Sure No Matter The UPS You Shouldnt Have Any Issues, In My Opinion Active-PFC Is A MUST

    Be-Sure The PSU You Choose Has Enough Connectors For Your Components (ESPECIALLY The Graphics Card/Cards) Thus The Reason I Reccomend PC Power&Coolng
