Hi all
I'm hitting a wall here trying to re-use old components to make a "light gaming" rig for a friend of mine.
I'm using aforementioned motherboard with a quad core 2.4 GHZ CPU and 8 gigs of Dominator memory. Everything works fine with and older geforce card using a six-pin power connector, but I wanted to upgrade it with an old HD7950 I had sitting in a drawer.
The case was fitted with an old Thermaltake toughpower 750Watt PSU, but unfortunately I don't have the PCI-E connectors for it. I tried using some adapters for molex, but couldn't get picture.
I fitted another PSU I snatched from someone who never got to use it, but was going to throw it away, a Corsair CX600 to test with. Despite it having two 6+2 pin PCI-E connectors I still can't get picture. Finally tossed it in my own workstation with an 850W PSU and that worked fine.
So the card works, I just can't get anything to display when I throw it in the older rig.
During the power-on process the fans spin briefly, but nothing further happens. It's not like I can connect a monitor to the motherboard directly. The LED's light up just fine and stay lit.
Is it possible the PCI-E slot simply doesn't provide enough power for this GPU? It seems so unlikely because this damn motherboard has no less than three PCI-E slots!
I was really hoping to make his kids happy with a rebuilt rig but it seems like it's just not happening.
Anyone got any ideas?
