New graphics card needed - 300W power supply

Then aim for a 6670:

That one has GDDR5 (that's why is a tad higher) which gives you a very good boost in performance. It will handle MW2 with no problems and also doesn't use extra power.

Cheers!

Another thing... My power supply is the following model: Bestec ATX-300-12Z.
I'm looking at the specs (http://www.power-on.com/atx12vhp300bt.html) and I'm not sure whether the EVGA GeForce GT 240 SuperClockedmeets the minimum recommended settings of "power supply with +12 Volt current rating of 18 Amps"

(http://www.evga.com/products/moreInfo.asp?pn=512-P3-124...)

Any ideas?

It does: DC Outputs (Amps Max/Min): +3.3V (28/0.5A), +5V (30/1.0A), +12V (19/1.0A), -12V (0.8/0.0A), +5VSB (2.0/0.0A).

Notice the +12V (1A-19A range).

Cheers!

Thanks but according to Sapphire's website, a 400W power supply is required

What matters the most is the +12V rail, like the GT240's site stated.

And 19A for a 6670 is plenty. Besides, that card doesn't use a lot of power, it's very efficient. You can trust me on that one.

Here's a power measure of the cards: http://www.tomshardware.com/reviews/radeon-hd-6570-rade...

EDIT: Here's Anand's review of the power used: http://www.anandtech.com/show/4278/amds-radeon-hd-6670-...

Do you think it could run on a 250w PSU? :3

i think needs PSU calculator, for all the hardware requirements can be fulfilled with a 300W. http://www.extreme.outervision.com/psucalculatorlite.js...

It actually depends on the PSU itself... If it gives at least 17A on the 12V rails, yes it could with no much hardware attached to it (lot of HDD's, DVDRW's, etc).

Cheers!

Thanks guys. I think I'll settle on the EVGA 240 GT SC... I realize it's not as good as the 6670 but I found one for $50. Thanks for your help.
