I have recently built a sandy bridge pc with an EVGA GTX 460 FTW GPU, since I have some money left over from the build I am looking to maybe buy a second GTX 460 to put in SLI but I am unsure if my PSU has the necessary cabling/watts to power them both.
I have a Cooler Master Silent Pro M700 which has two PCI 6 pin connectors which are both currently powering my one GTX 460.
The GTX 460 I have came with two connectors which seem to convert two Molex connectors into one 6 pin connector, unfortunately I only have two free sata slots left on the PSU so if I am correct I would end up with a total of 3, 6 pin connectors.
Anyone have any ideas on how/if it would be possible to power two GTX 460's in SLI with my PSU?
Does the GTX 460 need both 6 pin connectors to run?
Since your PSU comes with:
- (1) ATX 20+4 pin mobo connector
- (1) AUX 12V 4+4 pin connector
- (2) 6+2 pin PCI-E connector
- (3) 3x SATA connector
- (1) 2 x 4 pin molex and 1 x floppy
- (1) 3x 4 pin molex
You say you are using everything except for 2 x SATA cables? Because you can get cable adapters for molex to pci-e, but I'm not sure if you have any free since you say you don't. Your video cards will each need the 2 x pci-e connectors.
I have a NZXT Phantom with 3x120mm fans and 1 200m fan and I am looking to add another 200mm as extra intake.
Do you mean that on the Molex connector were it has multiple ends along one cable I can use two of them to make one pci-e 6 pin?
If so dose that also work for the pci-e 6 pin connector as that also has multiple ends along the cable?
The Cooler Master Silent Pro M700 (RS-700-AMBA-D3) with its +12 Volt continuous current rating of 50 Amps is more than capable of powering a system with two GeForce GTX 460 graphics cards in 2-way SLI mode.
You'll need to use both the modular cable with 3 Molex connectors and the modular cable with the 2 Molex and 1 Floppy connectors to get the four 4-pin Molex connectors that you will need for the two 4-pin Molex to 6-pin PCI-E Power Adapters that were included in the graphics card package.
Connect one 4-pin Molex to 6-pin PCI-E Power Adapter to each modular cable. There should be one 4-pin Molex connector available for the fan controller in the NZXT Phantom.
