Best FX card on a 300w PSU

[Magusigne]

So, 300w stock HP psu. Far as i can tell...upper-mid level quality.

It's not going to have the extra molex to spare.

4670 or GT 240?

Best would be a low-power 9800GT. No plugs needed.

Also, I have read about Powercolor coming out with a low-power HD5750 - this would be the absolute best and fastest card available - no extra plugs required, takes all the needed power from the PCI-e slot. No idea if the card is out already though.

I am not sure if the 300W HP PS could run 9800GT, but I do know my Dell 300W PS has run a 512 mb HD4670 for the past year with no issues. Not a heavily loaded system, C2D 7300, 1 SATA HD, 1 DVD-RW, 3 gb of ram. Kind of depends on what else is in the box, multiple cores CPU, 4 sticks of ram, multiple DVD drives and many fans may be a bit much for even a 4670 with a 300W PSU. I just installed a Corsair 400W unit in a relative's HP to make sure the new HD4670 I got for them wouldn't have any issues. That system is an E6600 Quad, with 8 gb of ram and 2 hard drives. Figured it should have a safety margin, so I threw in the PSU along with the vid card. Hope it helps their 4 boys have a merrier Christmas.

either of those cards would likely be the death of that psu unless that HP has very low power dual core and only a DVD and HD. that psu is only "rated" at 19 amps on the 12v and likely cant even make 15-16 in real world conditions. again it really depends on the exact specs of that pc but even a 4670 could tax that cheaply made oem psu if that HP has a higher end dual core or quad core cpu and multiple drives.
