Will a 4670 run on 300W with 19A on the 12V?

choose ddr3 model , it is better .

Okay, you answered the 2nd questions but not the first.  

Have an answer for the first?

Can anyone answer the first question for me?

Bestec isn't a known brand to me, but the 4670 is actually pretty efficient running off just the PCI slot. The official recommended PSU is 400w, which is usually an inflated figure to compensate for low quality PSUs. Whether or not your PSU is too low of quality is really the deciding factor.

Here is a chart showing the consumption of a 4670 equipped system (with a C2Quad 9450) at 67 watts idle, 139 watts under load playing Crysis.

Personally, if it was my rig, I would be prepared to replace the PSU, but would try it anyway. I would have to do this knowing the risk of a PSU failing and taking system components with it.

I found this discussion on the exact same scenario as you, bestec 300w PSU + 4670:

Get the DDR3 512mb model. The GPU wouldn't be able to make use of much more, and the DDR2 version cripples the performance compared to DDR3. The small price difference is worth it for DDR3, but not for the 1gb model, imo.

Thanks for your reply. Guess I'll be getting the 512MB version.

Thanks everyone.

Or would anyone recommend a decent card that can safely run on 300W?

Or recommend a good PSU thats under about 30 bucks?

I got a ddr4 but I dont think it is any better then the ddr3. Anyways, i have mine running on a 340 watt, and I have no problem, but it is an antec

yes
