Hi,

I have a Dell Inspiron 580 with a i5 750, 6Gb Ram and 2 optical drives. Would the 300watt PSU cope with an ATI HD5670??

Thanks,

You should have a min of 400W PSU

how many amps are on the 12v rail? the 5670 gets all of its power from the pci-e slot so it should work.

Yes.

Dell PSUs are actually pretty good. They are a little conservative when it comes to the PSU rating. I'm not saying your 300w PSU is actually a 400W PSU; more like maybe 330w.

Overall, your system does not draw too much power. However, if you were considering the HD 5750, then I would recommend a PSU upgrade or simply say, "No".

HD5670 is a very efficient card and yes you can use 300W PSU to run that card...

I've got an inspiron 546 with the same PSU, and my new sapphire hd5670 is working just fine. Even when I overclock it with AMD Overdrive.

Dell PSUs are way underated.
I use and fix Dells extensively
Currently I have a Sapphire HD 4650 in a Dell Optilplex 745.
The PSU is 280w.
I pin modded and OCd my CPU from 1.8 to 2.4 ghz
and also OC my GPU.
Everything runs smooth.
In my old Dell Precision 450 I had multiple optical and HDs plus GPU and Soundcard
and according to PSU calculator
http://extreme.outervision.com/index.jsp
is said I needed minimal 475w.
I ran that system for years with original PSU and it is still working!
Dell PSUs if I got it right are Fortrons which is a good brand name.
I would stick with cards that dont need external power if you do not have the plug on the PSU.
You should be fine.
Enjoy
