5670 on a 300 Watt

[RedxRepublic]

Can I run a 5670 on 300 with +12v1 of 10 amps and +12v2 of 13 amps?

Other specs:
i3-530
2 x 2gb ddr3 ram
1 x 1tb HD
1 x DVD burner
1 x pci network card

Generally yes. Which PSU do you have?

 

[RedxRepublic]

Lite-on 300w ps-630106a

I know crappy... but on a really tight budget here....

The 5670 requires a minimum of 400 watts. Do not use that card on that PSU it will cause all sorts of PC killing issues.

Not True. http://answers.yahoo.com/question/index?qid=20110607023305AA5cf8L
HD 5670 doesn't need a 400W PSU. It should work fine on a 300W itself considering if it's a good one.

You can choose a HD 6670 as well as it too doesn't a auxillary power connector.

The manufacturer recommends 400 watts. According to the information you have provided the 5670 draws 208 watts at its peak. The i3 CPU draws 82 watts at peak. As 208 and 82 Watts = 290 watts then that leaves exactly 10 watts left over to run everything else on the system. RAM, HDD's, DVD Drive. USB, ESATA the list goes on. All that powered by 10 watts on a PSU that will be running at absolute capacity just to keep the PC going. 300 watts is not enough.

Wrong again.

The power consumption for a HD 5670 at full load is just over 80 W.

The one given by the manufacturer isn't true and it's just over on what's actually required. You'd only need a decent 300W PSU to run it and it doesn't need a auxillary power connector so it's okay.
PS: You can't just calculate the power like that. Most PSUs ( if they are good quality ones ) can exceed the wattage by a little.

Well I am taking a beating on this subject tonight. It seems you can get away with 224 watts running that configuration. Second thread I have had to defer to. My mistake.

If it starts acting up though I would look to the PSU first.

 

[Wamphryi]

My machine calculates it needs 488 watts

 

[Gman450]

What machine ?
