Hi Guys.

Just need some help.
Anyone know the difference between the following cards ... I haven't looked hard enough, but I can't find the difference where I have looked:

Asus EN9800GT HB/HTDI/512MB
Asus EN9800GT /HTDP/512MD3

And can you successfully SLI these two without issues?

How much better would these be in SLI as opposed to two 8800GT's?

Regards

Itai
 
From what i've read the I has HDMI out while the P has HDCP (don't think it has HDMI built into the card, have to use an adapter)

You won't see much of a performance increase going from two 8800s to the 9800 seeing as the 9800 is just a rebranded 8800 with slightly higher clocks iirc
 
Ok cool ... will just stick to the 8800's then :p ... thanks :)
SLI'ing two 8800GT Tops and using 1 8800GT Top in the 3rd PCI-E for dedicated physics (This setup will work right?) :)
 
Now I need help with some PSU confusion ... I currently have an Aerocool 620w ZeroDBA, but have come to the realisation it isn't going to power my setup.

As mentioned above ... I am going to be running 2 x 8800GT Tops in SLI with a 3rd 8800GT as a dedicated Physics card. I am going to be running this in a Striker 2 Formula with a Q6600 Overclocked. Also will have either 4gb or 8gb of RAM and a 500GB hard drive.

I know the Aerocool is not powerful enough in terms of Amperage ... but will a Gigabyte Odin GT 550w be enough?

Regards

Itai
 
It won't work, look at getting something in the likes of a Corsair HX620, a single 8800GT requires 24A on the 12v rail and a minimum 400w psu

the odin gt will handle 2 of the cards in SLI without any problems, not sure if it will handle 3 of them (doubt it will)
 
This whole Rail and amp thing confuses me a bit. I know the Odin has 4 x 12v rail at 18A each ... if the 8800GT only has one PCI-E in and needs 24A ... howcome it works on 1 18A rail (i.e. one PCI-E out from the PSU) ... it doesn't make sense to me.
 
It's taking 18A from that 12V rail and it's also taking power from the mobo

You can't just add the AMPs on the rails up too, my psu is also quad rail and has 18A on each rail, but mine can deliver a CONSTANT 50A across the rails

The odin GT might work, but you will be running it at it's max, it's a good idea to get a strong psu and have some power left in reserves than to get a weaker one and run it at it's max capacity, the more you load a PSU too the less efficient it becomes

Hope this helps
 
Thanks ... yeah, I know about the not adding up thing ... but how do you determine Constant 50A accross the rails? I know on the side of the Odin it shows 18A per rail, but says Max 41A

I think I need to buy a bigger PSU before I can achieve my goal :(
