I want buy graphic card...

hello
i want to buy a graphic card hd 6770 or GTS 450 and this Power Supply:



Is the power supply can hold the card together with the rest of the system?
What video card consumes less power during exercise?

thank you



the system:
Q6600 2.40GHZ
2GB RAM 800MHZ
MSI P43 NEO

The HD 6670 uses about 125w under load, which shouldn't tax your power supply too much, assuming that you don't have like 10 hard drives installed.

i have never heard of EZcool. Reading about it on the net... mmm
I would rather get a new psu than risk frying all of my computer and my new gfx card with that cheap junk.
BTW, 6790 have the same price, get that better.

I have and I've also melted at least three of them over the years.

With the advertised combined 36A on the 12V rails, that PSU should be able to run a 6750 or a 6770. I can't speak to the reliability or quality of the PSU and it appears that the labeling is false or at least misleading.

I'm not sure if the rating EZCool is advertising is for Max power or continuous power. Some unscrupulous mfrs advertise Max power to inflate the ratings of their products...and the prices. There is definitely something off with their ratings.
For example:
1. They state 12A for 12V1 and 24A for 12V2 for 36a combined. 36A is 432W therefore the combined output capacity for the 12V rails should be 432W.
2. The 5V is rated at 21A...105W.
3. 3.3V is rated at 15A...49.5W.
4. You should be able to add these wattage ratings to get an approximate max power that the PSU can provide.

If you add all of those outputs you get 586.5W, yet the PSU label clearly states the max power is 434W.

I personally would not trust this PSU with my PC equipment. Are there other PSU options that are available to you?

Both of those are quality PSU companies and either PSU would handle the 6770 that you want to use in your system.
