double post'n here

but someone is telling me that they are running 2 x 8800 GTS g92 in SLI on my PSU (though it is the StealthX not the GamesX

"The PSU is quad rail, which is the only reason it can handle it. If it was single rail, then it would want lots more amperage because the rest of the system would be drawing power too.. (fans, lights, mobo, cpu, hdd, cd drive, etc). Since the cards are running on their own rail, the psu handles it like a champ

"

quad rail or not, it says each rail is only 18A!
do 2 rails go to 1 card??

Well, according to nVidia, no, it cannot run 2 8800s regardless of G80 or G92.

However, I see that your powersupply does permit some over-current.

Supposedly, 12V3 and 12v4 can be overdrawn to 20.5 A. (See page 5.) That is the amperage needed for an 8800 GTS G80. An 8800 GT G92 needs about 19 A if my math and research are correct. I do not at all recommend running your power supply with a higher draw than it was designed to; you will certainly be shortening its life.

EDIT: I just looked up the StealthX. The stats are identical to the GameX; it just lacks the pretty blue LED. So if they are in fact telling the truth, your power supply would be sufficient.

what a gamble lol, 220 for 2 x GTS G92 SLI shipped

I just keep comming to the point if i should bother with this, or if the money is better spent on 1 4870 sicne my price for item at cost + shipping is in a difference of 20 dollars

Well, in the regard of power usage, a 4870 would be the better option. A single 4870 needs but 6.25 A according to ATI. Further, ATI Certifies your power supply to be able to power one. While there is no mention of the 4870 in the crossfire department, it supposedly can run a pair of 3850s. The 3850, like the 3870, 4850, and 4870, also requires 6.25 A as per ATI. So THEORETICALLY, you could keep this power supply if ever you crossfire a second 4870 when you build your AM3.

see now were talkin!

I thinkt his may be my overall favorite Idea

considering I will not exactly pull that much performance from SLI at my res, might as well just get a beefier single card liek the 4870
and will DEFFINITELY think of Xfire later on because I most likely Will build an AM3 after it has time to burn into the market =)

On the other hand; it is not certified for a 4870x2; maybe that means it cannot crossfire; who knows.

Oops, I made an oversight. A 4850 uses as much power as the 38x0. A 4870 uses two 6.25 A connectors. Still, ATI calls for 4 PCI-E connectors and 600 W total. Maybe you can cut the mustard; only way to know is to test it! *Nods at Joe.*

hmmm so strange

so i guess that ius the deal? 2 rails on the PSU goes to 2 card?

blitz6804 · 08-26-08

Right. If you get the 4870, two PCI-E rails get connected to it. If you get a 38x0 or a 4850, one PCI-E rail gets connected to it. I am sure the 4870 will also come with at least one adapter that turns molex connectors into a PCI-E. If it comes with two, this enables you to use a second card even if you do not have enough PCI-E rails.

o this hting has 4 of them doesnt it?

I found a DDRI ic list on the Corsair support forum but I wasn't able to find the exact module(s) on the list. I've submitted a reply to the thread for info regarding the modules to be added.

For those of you whose RAM may be already listed the thread can be found here.
