|I am building a new gaming rig and i need some input on power supplies. In the past i have used the Seasonc X660 and X750 and those were great. I'd like to get 2 used gtx 580s from ebay, hoping for $200 each, may be dreaming a bit here. Or i could buy 2 new gtx 660s. I know the 660 will use less power. Will an AX850 or X850 be suffiecient for 2 580s in sli? I am also taking into consideration that the new 780 will be out this month, but i have no idea of the power requirements. I guess it would be the same as the titan. |
Now lets talk brands. ive heard that seasonic and corsair are really the same.
Ive also looked at the XFX 750pro, and it has the same hybrid fan controller.
Im not sure if i need an 850 or 750 watt.
Proposed specs of build:
CM HAF 912
PHENOM QUAD CORE @ 4.0GHZ
2 X 4 GB HYPERX @ 1600
3 FANS-1 120mm and 2 200mm red led
580 SLI, 660 SLI, GTX 780
POWER SUPPLY: TO BE DETERMINED
My last rig had the seasonic X660 with 2 evga 448 classifed ultras (GF 110) overclocked to 970 mhz and the cpu at 4.0 ghz. The power supply had no problems with that, and yes i was quite surprised. But that was only for running benchmarks. During normal use, everything was at stock speeds.
Ok so whats the difference between the X650 and X660?
difference between X750 and X760?
Any differences in the 850s; seasonic, corsair, xfx?
My gut tells me to get an 850 and let it go at that.
Newegg had the XFX 850 on sale for $99.00. was that a closeout of a discontinued model?
I believe a 3 of these brands are really made by seasonic, but this time i wanna save a little money. I dont automatically buy everything from newegg as i have in the past.
Last January, I bought 2 sticks of kingston hyperx ddr3 1866gx (2 x 4gb) for 49.99. that same memory today is $92.00. What the hell happened with ram?
Enough for now and thanks for any help you may give.
ignore the specs for the emachines, thats just my regular desktop.
