6950 1gb and 2gb 650w?

[Masterdeadly]

Hey guys

my system currently has an amd 955 clocked from 3.2 to 3.61, a single 6950 1gb, 8gb xms3 1600mhz corsair ram and a seagate barricuda 500g

If I was to add another 6950 2gb will 650w be enough?

Its a 2 year old power supply so I cant find it on overclockers website but I believe it's a high standard one

any comments?

I'm sorry fowler, I made the same post on accident I couldn't see it so i made another

Tx 650w Corsair PSU

But both the cards take 506 Watts what about my 955 black edition 3.61ghz?, ram and hdd card surely they take some Watts

And you're running quite a heavy overclock with your i7 Thanks for advise man

 

[Masterdeadly]

What program should I use for checking GPU's temps and whats normal and whats not?

 

[Masterdeadly]

And if you're pulling 500W from the mains the PSU would only be outputting 425W assuming it was 85% efficient.

So you're saying it'll be enough?

 

[Masterdeadly]

Any other inputs ? if you think it's enough power?

The molex adapters won't reach to the second card I don't think Gonna have to do 2 proper PCI-E into one card and the 2 molex adapters into another.

New ??

Well I'm still waiting a response from overclocker's as i'm willing to pay the difference to upgrade my HIS 1GB 6950 to a 2GB OcUk as I doubt they have stock of the HIS 1GB 6950.

Fowler I can't connect my cards like this the Molex adapters simply won't reach,.

 

[Masterdeadly]

Any suggestions how I should connect my 6950's? Will have 2 "proper" pci-e cables for one card and two molex adapters for the other card will that work fine?

Anyone with two 6950's that can help me?
