Is my PSU enough for a DirectX 11 card?

Talrinys said:
New boards have PCI-E 2 which doubles the bandwidth per lanes, designed for newer cards, i'm not sure how CPU-Z would show it, but i'm absolutely convinced that the current bandwidth with a PCI-E1 16x link will not be enough for the new cards. That doesn't mean you might not see an improvement, just that in some/many cases you won't see max output of the card.

Thanks for that.

My mobo is a budget model so it probably won't have this feature - it's a Foxconn G31MX Series.

If I won't benefit fully from the new DirectX 11 cards (when they are released) then I may as well upgrade my graphics card to either a GTX 285 or GTX 295 (if my 600W PSU can handle it even though Nvidia states that a 680W PSU is required as has been pointed out a few posts ago)

"I was going to upgrade to a GTX 285 but was advised to wait for the next generation of graphics cards (my PSU isn't up to powering a GTX 295 as it requires a minimum 680W PSU according to Nvidia)"


And that's complete and utter twaddle from Nvidia too.

Yes they always seems to grossly overstate the "minimum" required PSU for all cards. I suppose they just want to be on the ultra conservative side of safe. I recently installed a 4670 in my brother's Dell, the 4670 box said it needed a "minimum 400 watt PSU" but it works perfectly with a 305 watt PSU.

OP: use a power supply calculator, like this one: http://extreme.outervision.com/psucalculatorlite.jsp
to see how much headroom you've got for your graphics card. 600W should be fine depending on its efficiency.

Well according to the official specs, my 600W OCZ PSU has 4x12v rails each of 18A making a total of 72A - is this good :confused:

I think that a PCI-E card uses the 12v rails?
 
Doesn't work like that unfotunately - it won't be the rail values added it'll be a bit less. Maybe 60-64A or so.

I think my 1.1kw tagan is 72A on the 12v rail despite having 6x 20A rails.
