Title: How many GPU for 630W PSU? Post by: ak84 on December 22, 2013, 01:26:00 AM Hi all, I"m wondering how many GPU my power supply can support. I have a 630W RaidMax http://www.newegg.com/Product/Product.aspx?Item=N82E16817152035 (http://www.newegg.com/Product/Product.aspx?Item=N82E16817152035)
which is powering a GTX 660 TI (150 Watts max according to nvidia website) I guess my PSU could probably handle another 200W rated GPU such as 5850, 5870, etc. Do you think it can also handle a 3rd, like a hd 5770? (only requires 108 watts) edit: after doing much research, it seems adding 3rd GPU might be pushing it, even if that gpu only takes 108 W Title: Re: How many GPU for 630W PSU?

don't even think about it! Title: Re: How many GPU for 630W PSU? Post by: DarkKnight on December 22, 2013, 07:31:51 PM 528w max on the 12v rail... Nevermind that running it near capacity for extended periods will burn out your PSU quickly.

Not worth the power costs, even if *you* aren't paying the power bill. Title: Re: How many GPU for 630W PSU?

Well I recently bought a 750W Corsair HX http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010 This can handle two GPU right? 6870 x2 or 5850 x2 Thanks Title: Re: How many GPU for 630W PSU?
