    Will 650W be enough for my 460 SLI?

    After getting a lot of good answers from the other thread and doing some more research myself, I've decided to upgrade from my GTX280.

    I just ordered two of these cards: http://www.newegg.com/Product/Produc...82E16814125333 and now I'm worried that my PSU might not be able to handle it.

    I'm building a new system from scratch, and I will be putting everything together minus the 460s tonight. In their place I will be using a single GTX280 until the new cards arrive.

    So, I've got some questions:
    1) Does have two cards increase the Tessellation capabilities of the setup?
    2) Can the 460 handle DX11 well?
    3) Is Tessellation and DX11 important? It's part of the reason I upgraded from my GTX280.
    4) Will my 650 Watt antec PSU be enough?
    5) I plan on overclocking my CPU, but I've never done any OCing before. Do I need some special software? What is this CPU-Z and GPU-Z I keep hearing about?

    The rest of my rig:
    MOBO -Gigabyte GA-X58a-UD3R
    Processor - i7 930 Bloomfield
    Memory - Corsair TR3X6G1333C9 XMS3 6 GB 3 x 2 GB PC3-10666 1333MHz 240-Pin DDR3 Core i7 Memory Kit
    HDD - Samsung F3 Spinpoint 1 TB 7200 rpm, 2x old IDE drives with about 120-140 GB capacity each
    Optic drive - Sony Optiarc Black 24x DVD+R
    Case - Antec 300 (has 3x 120mm fans, 1x 140mm fan)
    Peripherals - Logitech MX518 mouse, Logitech G15 Keyboard, Logitech headset
    Monitor (has own power source) - ASUS VH236H 23 Inch Widescreen LCD

    1. Yes. but not 2x its dependent on scaling.
    2. Yes, the 460 is a DX11 card.
    3. Yes, if you play DX11 games which include tesselation (BFBC2 is one I can think of)
    4. It should be fine.
    5. You need to read the link in my sig (i7 overclocking guide). You can google CPUz/GPUz, but they are just programs that show some needed statistics such as clock and bus speeds, voltages, memory speed and stock speeds, etc.

    I still would have went with the 470, especially considering the price drops lately ($250 for one of those now). I know 460 1gb in SLI beats them but... I dont like SLI/Crossfire b/c if I pay 2x, I want 2x performance all the time, not 1% of the time. Scaling on average is around 70% or so.

    I'm sure the 480 is sweet, but the best price I've seen so far is about $500. That's about a 42% increase in price over my SLI combo...

    Out of curiosity...what about compared to a 480? Is 460 SLI > 480?

    It's certainly less expensive...

    i hope you didnt pay 440 for the 2 cards. THese 2 were on sale for 320 total, after the rebate (see cyber deals)

    i7 will to to ~3.6 without even touching the voltages.

    The GTX460 SLI setup generally outperforms the GTX480:

    http://www.tomshardware.com/reviews/...80,2694-9.html

    But power usage is slightly increased over one GTX480 (only slightly, more performance per watt with the SLI setup)

    I was the one who put up that cyberdeal

    Badbonji:How much do the 460s use? 160 watts each?

    Yes, 160W each. Vs 480 that is 250.

    Power consumption for the 1GB models in SLI
    http://www.hexus.net/content/item.php?item=25498&page=9

    Overall it isn't much more than the GTX480, the increase in performance is more than the power increase %-wise.

    Thanks Earthdog, Badbonji!

    Earthdog, the link in your thread is the updated version of the original guide right? The author is not you right?

    Building New System - 1st in a long, long time.

    New to the site and would like to ask whether you folks think I have enough power supply in this new system I'm putting together, my first since about 1995:

    Asus P6T Deluxe V2 MoBo
    Antec 1200 case
    Antec 1000w psu
    i7 950 CPU
    12 GB RAM
    120 GB SSD (1)
    1T HD (2)
    MSi N460GTX Hawk 1 GB GDDR5 Graphics Cards - SLI'd (2)

    Reason I'm asking is the MSi box recommends 450W for just 1 video card. I sure appreciate any feedback I can get.

    Sorry; should have also mentioned that each of the 460 GTX's seems to require 4 molex connectors, which has me wondering about cabling issues.

    Well you get converters and most PSU's have 4 molex connectors.

    Thanks for replying. Each of the converter cables does three, that gives me a possibility of six, but the two video cards together are needing a total of eight molex terminations. Any ideas on whether the 1000w will be enough?

    Get a PCI power splitter. Turns one 6-pin power connector into two.

    All along you should have been thinking buying a new PS and getting 460 SLI and using dedicated 280 for physX(or sell the 280 to someone with a dual 280 system so they can go TRISLI and buy a third 460 with the money). Three card setup = You won't be sorry.

    I'm running 3 GTX 280's on my Corsair 1000HX. It's a good power supply in my opinion but I'm sure there are better ones. If I can run this you can run 2 460's and a 280.
