Hello khirty2000;

You didn't mention what else that XPOWER780 PSU will be powering besides the ASUS ROG Matrix 5870.
And that's important because the XPOWER780 is actually a 600W PSU. I know that 780 is misleading but when you look at the data plate this is what you see:

Total output 600W, MAX. output 780W

While the PSU can PEAK at 780W it's continuous rating is actually 600W.

This HardOCP review of the ASUS ROG Matrix 5870 shows the power requirements in a system with an OC'd i7 920 (see page 2 of review for full system specs) range from 437W at full load to 524W with the ROG Matrix 5870 further overclocked.

My opinion is that the Hec XPOWER780 PSU is not a good choice for a serious gaming system and doesnt match the quality or total power requirements of the ASUS ROG Matrix 5870 in a high end gaming system.

a corsair 650hx would be more suitable. hec doesnt make very good power supplies.

Yes there are. In fact there should be one adapter in the accessory pack of the card.

OK, there are two 6 to 8 adapters. But they 'adapt' 2x 6 pin PCI-e power leads into 1 8pin. Since you're on just 1x6 and 1x8 you're missing the 2nd x6 power lead to fill out the 6 to 8 adapter.

It's still not too late to go out and get a new power supply.
