"One Dual-Width x16 Graphics Slot" - What does that mean?

[AUS_Doug]

Here is the Graphics Card in question:
http://www.pccasegear.com/index.php?main_page=product_info&products_id=21456

The requirement that worry's me
"PCI Express-compliant motherboard with one dual-width x 16 graphics slot"

I DO know that my board has a PCI-E slot, but I'm not sure what they mean by "dual-width x 16 graphics slot"

If it helps, my PC is an e-machines EL1850.
And don't worry, I know the PSU in that is crap and tiny and useless, and that this card wouldn't fit in the case anyway.
But I've taken care of both those problems. (Already got the new case, just deciding on the PSU now)

Thanks in advance,
AUS_Doug

It means the card will fit into a single PCIe x16 slot, but the card is as wide as two cards and will take 2 slots at the back of the case.

You have a different issue with your computer thou.
It has a weak power supply, it is only 220w. You may need a bigger one.

Yep, I know.
Mentioned that in the OP.
Thanks for the heads-up though.

One more thing:
I might just be a victim of my own nervousness here, but it says "x16" graphics slot.
I'm not sure if mine is "x16"
Or are all PCI-E slots "x16"?
