Will my Power Supply handle this?

[g4kioN1]

right now i'm running a
750 WATT OEM ATX PSU
i want to upgrade to a GTX 260 but in order to get the full potential out of it i have to buy a new processor. in the future i plan to upgrade to a 790 board with ddr3 but if i get a gtx 260 i want to have them sli eventually.

Can i run this with 750?

AMD Phenom II X4 965 Black Edition
COOLER MASTER v8
G.SKILL Ripjaws Series 4GB (2 x 2GB)
EVGA 896-P3-1257-AR GeForce GTX 260 Core 216 Superclocked
EVGA 896-P3-1257-AR GeForce GTX 260 Core 216 Superclocked (sli)
ASUS M4A78T-E AM3 AMD 790GX

with my 2 dvd drives, 320 gb HDD, With the Alienware Predator Chasis (lights)
Razer Mouse/keyboard (lights)

if i cannot run this with 750 can i run GTS 250 in sli? if i can which ones, 512 or 1gb

if i can't run those i'll probably just buy another 9600 gt superclock and sli those.

thanks guys please help me out

When i buy a second card for sli. do all of the specs have to match up, 512mb and 1 gb, or do i have to have 512 and 512?

could you give the 12v output on that 750 watt or the full specifications that are on the label on the power supply,the thing is not all power supplies are made equal some are crap some are excellent it just depends on who the manufacturer is

there are few amd am3 boards that can sli

its recommended that sli/crossfire specs are the same but its not critical it just means that the better card will default to the lower cards specs

The motherboard does not support sli as it is an amd/ati chipset. The nvidia chipset for amd chipsets are just not good. Also post you power supply model and specs so that we can see if it is capable, which right now I am doubting as it is a no name PSU. also post the resolution you will be using. GTX 260' cost about $200 which is not worth the money. 5770's that perform similarly are priced at around $160 and have more features notably DX11. This one is under $140 and overclocks very well.

The cards should have the same specs otherwise you will not be able to use one of the cards to its full potential. You could use a 1gb and 512mb together, but only 512mb of the 1gb will be used.

sounds like a generic PSU - dump it and get something decent

GTX260's are old stock and DX10 parts, me personally i would avoid them.

its alienware
1600x900

So i've decided to run 2x Radeon HD 5770 1GB 128-bit GDDR5 in crossfire instead of nvidia

 

[obsidian86]

im gonna put it down that that 750 looks to be a delta design so you should be fine with 5770's but i'd actually get a 5850 then later add another one

 

[g4kioN1]

Well that's what i was doing, I'm adding all of these things later but that will be my rig in the future. Right now I'm running a 9550, 780 mobo, ddr2 ram, 9600 gt. i was trying to figure what i should upgrade with so that i can future proof my system. The 5850 is way out of my price range lol.

 

[obsidian86]

so how are you getting $300 for 2 5770's

 

[g4kioN1]

I'm getting 1 5770, and then I'll be getting a phenom II since my MOBO is AM2+. Eventually I'll be upgrading to a 64 bit system and getting a new motherboard with ddr3 ram. When i need better graphic performance I'll just add another 5770. I'm running a 9550 that will bottleneck my graphic card it would be a waste to upgrade to a 5850 without getting a new processor.
