As title says..I was just thinking about to add another GTX275 in near future
but when I looked at my HX620 lol, something tells me I need a better PSU
Since buying another HX750/850 will cost me another 200~300USD
So I'm thinking of using 4 molex pin and convert into 2 PCI-E power pin
Since HX620 has 2 PCI-E power pin and combine with the another 2 PCI-E power pin and that makes 4 PCI-E which is required for 2 GTX 275, and I gonna spread it like this, one GTX275 will get one direct from the PSU and one from 2 molex pin.
So...my specs are
i7 920@3.7GHz@1.275v
3x1GB Kingston DDR3-1600
Asus P6T
1 WD 640GB HDD
1 DVD-RW
And I did some research from wiki, it says single GTX275 TDP is 219W and 2 of them makes 438W, but my PSU is rated at 620W
Adding my i7 takes up 130W and that makes 568W..
Just thinking is it enough for 2 GTX275 ?
Thanks in advance
