6670 on a 300 watt with upper-medium specs

[abg123rocks]

I currently have an HP with an i5 3.1 Ghz, 6GB DDR3 Ram, a 300 watt PSU and 6450 graphics. If I were to swap the 6450 with 6670. P.S. a 5670 and a 6670 have take the same power.

Can you mention the model of that HP desktop that you have?
The HD 6670 or a HD 5670 doesn't require an external pci-e connector, so it should run well on 300-350W PSUs considering that they are of good quality.

you definitely need to change your psu, as 6670 requires 5 times more power on full load compared to 6450.
component max power consumption
6670 125w
6450 25w
i5 140-150w

so as you can see i5+6670=275 watt of true power consumption at their max load, note that hard disk drive, cd drive , ram, extra cooling fans are not included in power.
so conclusion is that upgrade your power supply around 400watt of true power

Yah okay I was just asking cuz I'm poor

Don't worry.
Just buy a good PSU. One from reputable brands like Antec, Corsair, HEC, XFX etc.
Here's really a good, solid $40 PSU from Antec. It's more than enough to power a HD 6850.

What about this Seventeam 550 Watt for 50 AUD, which I read works well at high temperatures and works at 80% efficiency.
Or this Thermaltake 500 Watt for 49 AUD, which I hear has a small boom boom rate.
Are any of the above realistic choices? If so which?

 

[Gman450]

It should be okay.

 

[abg123rocks]

Are you serious? Than what would you consider cheap and horrible?

 

[Gman450]

Cheap and horrible ones would be the PSUs from iball, zeberonics etc. They don't last long at all and won't be able to handle mid-range or even some low end ones as well. It's those kind of PSUs that you need to stay away from....

Thanks just one more thing, I was afraid to ask this before but, what about A-Power?

 

[Gman450]

I'd stay away from A-power. Look for the brands I had mentioned in my second post.
