Is a 450W PSU ok?

Basically, I live in India. The power goes out alot. My apartment has full power backup but it takes about 5 minutes MAX to bring the power back. So for my PC build, I'd like a small voltage PSU which can work on 220V input from the wall (socket). I also need to buy a UPS (uninterrupting power supply) to keep the PC running. Advice on what PSU and UPS to get?? Preferred site: anywhere that delivers to India or the UK :) Don't want to spend over about 350 USD for both :) cheaper the better :) hopefully still reliable.

Advice on what UPS and PSU to get for following build
PSU and UPS need to work on 220V supply and support if power off for 5 mins. :) THANK YOU
Heres my build (used for gaming) :

Intel i5 2500k Sandy Bridge (I am aware of the ivy bridge processors but am using this CPU for an estimate)
Prolimatech PRO-MGH-C CPU cooler
Asrock z77 Extreme 4 - MOBO
G.Skill Ares Series 8GB - RAM
Western Digital Caviar Black 1TB - HDD
GTX 680 - GPU
NZXT Phantom Full Tower Case - Case
Asus - BC12B1ST - CD drive

More about 450w

    That is a good PSU, and will be sufficient for your system.

    Get a UPS from Cyberpower, APC, or Tripp-Lite.
  2. But will a 450W PSU suffice?
  3. and the one you suggested supported only 650W while the PSU above is 750?? Will it still work????
  4. if your going with a K processor and a high end motherboard for overclocking, skimping out on the psu would not be a good idea, or that kinda nullifies the use of the high end mobo and the K series i5/i7 processors.
  5. Hmmm very true. So would the UPS that was mentioned ^^ be able to support the 750W PSU for 5 mins??
  6. ????
