500W Power supply with an XFX 6790?

[ghostlow]

Afternoon chaps, I am planning on buying this graphics card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150564

For my ALREADY BUILT system with this power supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171031

I know the GFX card requires 2 6 pin connectors, seeing as my power supply only includes one 6 pin connector, i was planning on solving that "issue" with a cable like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16812201004

So, my question is, will these connections provide the power that the 6790 requires? my main concern is the wattage on the power supply, seeing as XFX recommends 500W or greater. I am pretty confident my power supply is reliable because i have had no problems in 4 weeks since i bought it, which within that time frame is when most PSU problems surface.

If it matters, this is the list of links of the products in my computer:

Not the best PSU in the world, but with a MOLEX to PCI-E (6-pin) adapter, you should be fine. I wouldn't recommend OCing this system given this PSU, however.

Good luck!

It looks like the 6790 draws a max of ~ 10 amps. so even thought the CM 500W PSU is an average PSU, it *should* be OK and the cable adapter should work fine also.
