| oodles2do said: I agree with waiting for 3rd party cards, this PC is the first that I've custom configured and I don't really know much about motherboards. What do I need for dual PCI-E power? Is that simply from the power supply? The board that I've had to go for (to stick to the configurator on the website) has 1 PCI-E slot for GPU's. |
GPU's are allowed to draw up-to 75 watts of power from the PCI-E slot on the motherboard.
The rest comes from the PCI-E 6/8-pin power cables from the power supply unit, 6 pin PCI-E power cables will provide an extra 75w of power, whilst the 8-pin (Which are actually 6+2 these days) power cables can do up-to 150 watts.
Polaris thus draws upwards of 75 watts of energy from the PCI-E slot on the motherboard and another 75 watts from a 6 pin PCI-E cable... It's a power wall that could potentially limit overclocking.
There are some PSU's that also benefit from a GPU having two 6-pin PCI-E cable support rather than a single 8-pin due to load balancing of multiple 12v rails.
Your motherboard should be all good either way.
