I Have Question For You...

GAMERIG · Dec 18, 2009, 09:05 PM

Hi,

I got 2XGTS 250 for SLI.

Now My question is: I can install on MSI mainboard SLI with eXtreme Power Plus 460W Regular, it will be fine?

I need your feedback asap, thanks in advance..

erocker · Dec 18, 2009, 09:08 PM

No. Not enough PCI-E connectors, not enough Amps on the 12v rail and not enough watts.

Yes, i ask you why i have not enough watts? I have extra PCIe adpater from evga gpu box .. I did read manual, there did not say anything power supply unit as requirement.

On Nvidia's website it states one card needs a 450W PSU. The wattage isn't really the important thing here though, that PSU doesn't provide enough amperage to run two cards. Look for a PSU that has a sufficient amount of PCI-E connectors and at least 20 amps per card on the 12v rail. So something with about 40 amps total.

johnspack · Dec 18, 2009, 09:23 PM

Get a Corsair, preferably a TX750, but a TX650 would do for you. Don't use a cheap power supply, it can ruin your equipment. Check this egg entry:http://www.newegg.com/Product/Produc...82E16817139005 I would look for this kind of amperage on the 12v line ect.

Paulieg · Dec 18, 2009, 09:24 PM

Erocker is 100% correct here. If you try running this with your power supply, you will kill it and no telling whether you'll take other components with it. DON'T mess with less than adequate power supplies, and ALWAYS stick with quality brands.

+1 on this but if you can get more (20+) on 12v rail the better

John, AWESOME! thank you for recommend me tht PSU. I believe that Fry has Corsair power supplies for PC. but how about Cooler Master Silent 700w? Next week, I will get one from frys which is location near where i live.

Yeah, how can i get more 20+ on 12v?

thanks for replied my post, quickly..

johnspack · Dec 18, 2009, 09:55 PM

The corsair tx650 has 50amps for the 12v rail. The tx750 which I have, has 60amps. Trust me, it is sufficient!

bogmali · Dec 18, 2009, 10:00 PM

TX650 is what you need.......If this makes you feel any better, I'm running 4XGTS-250's in one of my folding farms with that PSU

Look in the very bottom of this page and you'll see it

No reason not to go with the TX750W if it's only $10 more. Get it and it will serve you well for years to come.

johnspack · Dec 18, 2009, 10:29 PM

I love my tx750, it's a beast! It should run 2 gtx285s no problem. Possibly even 2 gtx295s! Edit: it supports 4 8 pin video connectors, you can plug anything in!

GAMERIG · Dec 18, 2009, 10:33 PM

Joe, Ha, thats true... thank for responses me back quick..

I already decide to go with the TX750W. I can't wait to install my sweet 2X GTS 250 SLI on my rig, when getta the TX750W before xmas.
