Don't know if PSU can handle some upgrades

Currently I am running an older(4 years old if it matters) Antec 400W Earthwatts PSU. I'm trying to do some system upgrades, but I don't know if the PSU can handle them.

I am currently trying to update my video card, and have been looking at a Radeon 6770 or an Nvidia 450, but I don't know if my PSU can handle them, or what the upward extent is of cards it could handle is in the first place.

Current Specs:
Gigabyte 880GM-D2H Motherboard
AMD Phenom 955 Black Edition Processor
Nvidia Xforce 9600 GT Video card
1TB Western Digital HD
500MB HD(forget brand, can be removed if there is power constraints)
SuperTalent 4GB RAM

  1. Do you know if that PSU is 80+ certified or can you provide a link to your exact PSU?
  2. Seems I was slightly wrong on my watts. The model is EA-430D, and at least in the manual it mentions 80+ from what I read.
  3. It'll handle it easily. Those are low power GPUs.

    both cards are in the same ballpark as the 9600GT in power needs. you have plenty of power and can even step up to a GTX460. stressed; the following system won't break 300w, gaming would be even less. the amd 6770 is just the old ati 5770 re-named.

    Test System Specs
    - Intel Core i7 920 (Overclocked @ 3.70GHz)
    - x3 2GB G.Skill DDR3 PC3-12800 (CAS 9-9-9-24)
    - Asus P6T Deluxe (Intel X58)
