Default Corsair HX620 psu, enough to run GTX670?


Plan on buying this card

Gigabyte GTX 670 [Link]

the link does not tell you what the minimum watts and amps are for this card, but looking at other 670s, they say 500watts and 30amps on +12 rail. although my psu is 620w im not sure about the amps?

Corsair HX620 specs [Here] (Info at bottom of page)

Also are all these cards backward compatable? , as my mb only has PCI Express 1.0 (Gigabyte GA-P35-DS3R)

Pc is not OC

That PSU will be ample. I've run a much more power-hungry GTX480 on my 560W unit without any trouble at all.

With that said, itís an older unit and looks about 80 plus, so maybe try a newer gold/platinum version if you're shopping for a new PSU? You'll get about 10-15% more efficiency and this will be quite noticeable in terms of less heat output.

But for an older unit, itís very good.

And PCIe is backward and forward compatible, though some older motherboards may need a BIOS update to see newer cards.

PCIe 1.0 may not be compatible with PCIe 3.0 hardware... IIRC the full backwards compatibility only goes back to PCIe 1.1

I have a P35-DS3R v1.0 rev, and I've used HD4850, and GTX460 1GB cards in it, no problem. I have yet to try a PCI-E 3.0 card in it, but I have no reason to believe that it wouldn't work.

Thanks for the replys

found this post on anandtech [Link]

Post says will work on pci-e 1.0 but as my cpu is a E6750 (2 core @2.66),
which will be a bottleneck for cpu dependent games.

Was planing to upgrade the whole system next year, thought I could get the gf card in the meantime. Ill give it more thought.
