Power usage question for gfx card upgrade

I need to know whether my current PSU can handle a gfx card upgrade:

My current specs-

PSU - iBall JSW 252 400w (The vendor said it's a 400w psu but i'm not sure if that's true)
Processor - E2160 stock 1.8ghz overclocked to 2.33 ghz (1.325v)
Motherboard - Gigagbye G41-M combo
RAM - Kingston 2gb DDR3 @ 1333 mhz
SATA 2.0 160 gb hdd
3x 80mm cabinet fans
As for the dvd rom, I plug it in only when it's required, so you could say no dvd rom.
Current gfx card - Palit geforce 8400gs 512mb stock 567 mhz overclocked to 720 mhz

New gfx card - HIS HD 6670 GDDR5 1GB

Side note: The new micro atx PSU upgrade is not possible due to a really old cabinet, might buy a zebronics 450w ATX PSU if my current one doesn't supply enough juice. open for suggestions.

  1. It's not a very good PSU , I would change it to this one below.

    PCPartPicker part list / Price breakdown by merchant / Benchmarks

    Power Supply: Corsair CX 430W 80 PLUS Bronze Certified ATX12V Power Supply ($34.99 @ Microcenter)
    Total: $34.99
    (Prices include shipping, taxes, and discounts when available.)

  2. Hi. 400W for 6670 is more than enough. But if your PSU is like 8 years old it can lose some ampers and wattage.
  3. Looks like you are buying in India. Refrain from buying Zebronics or iball and such brands. Buy a product from a reputed manufacturer. Remember that a good PSU will be needed for system's stability and long-term reliability. Based on your configuration, you can search Flipkart for a 400-450W 80plus bronze PSU. Within 2-3k you should find what you need. As blackbird suggested, corsair will be a safe bet.

    Yeah the PSU is pretty old but I bought it brand new last year.

    I'm extremely sorry I forgot to mention I'm on a budget as well and can only go upto Rs. 900 for a PSU upgrade, I do understand iball and zebronics brands are pretty bad but iball has been running pretty smoothly for the past 1 year, and zebronic's 450 atx psu's price which is Rs. 500 (about $8) fits my budget.
  7. I wouldn't go cheap on the PSU , you put your components at risk.
  8. Thanks for all your replies, looks like i'll settle for the corsair vs450 PSU, didn't even realize there's a huge risk involved when dealing with unbranded PSUs. Much appreciated.
  9. Your welcome!
