Based on my system specs, would it work? My PSU has a 6+2 pin and a 6 pin PCI-E power connection so...

Without even knowing what type of PSU you have, I'd say no. The 5970 draws 300W+ alone under load depending on your cards OC. Then you have probably 100W+ from your CPU under load..... Things add up.

Good test showing system loads.

*edit* Adding a nice article about the card itself.

 

[slothfish]

ABSOLUTELY not

 

[Diabolical999]

It'll power it. But gaming under load, is a different story. Wouldn't try it on anything other than a PCP&C or Corsair, though.

 

[Weedvender]

Seasonic, Antec, Corsair, PCP&C, etc. Take ur pick.

That's the one I have.

41 amps on the 12v, which is what you really need to look at. You'll be pushing it, but it should work.

AMD recommends a 750W PSU for the 5970 but the VX550 is a very good PSU. If I were you I'd try it but NOT BEFORE I HAVE ADDED UP ALL THE POWER YOUR SYSTEM DRAWS COMBINED. That means CPU, Fans, HDD's, just about everything. Reason why? Because using a VX550 on that GPU would be cutting it VERY close.

That's what I thought, yeah. I only have one HDD and DVD drive. Two 120 MM fan.

Dude, I meant really get into specs and how much every little component draws and add it up.

My recommendation is still no, though. Your PSU is 200W below what AMD recommends. Note that I said "If I were you...".

Worst case scenario what would happen?

Your PSU has 41A/492W on the 12V rail.

Don't do it.

Although I know that all the load isn't going to be on the 12V rail, you shouldn't try it, in my opinion.

The worst that can happen is your power supply dies, and takes several components to the grave with it. That shouldn't happen with this power supply, it should just shut down, but I don't think you should try it.

 

[solidsteel144]

It could really take out the PSU?! I thought like you mentioned it would just shut off as if nothing happened.

Worst case scenario = PSU at the limit thus producing serious ripple and/or shutdown thereby frying your motherboard among other things.

Best case scenario = PSU shuts down.

If you wanna risk frying your system go ahead. Dude, go for a TX/HX750 or a TX/HX850 They're not that expensive compared to that graphics card. Cheap insurance if you ask me.

 

[slothfish]

You're willing to spend $600+ on a GPU but not on a power supply that can handle it?

Not at the very least.

That good enough?

That's why I'm asking to see if maybe, just maybe my current PSU can take it.

Yes, the Corsair TX850 would be enough and then some for the HD5970. I'd probably say you could do TriFire with another HD5870 in there too on there.

You could go for the Corsair TX750 if you wanted to save some money though.

 

[H4rd5tyl3]

Was wondering the same question, but with a Xigmatek 750W PSU.

Yes, you would be fine with that power supply.
