Will this PSU fill my needs ??

Hello and good afternoon Lads!

Will this PSU be good enough for my system?

Corsair 1000 HX 80+.

System setup:
i7 920 - OC @ 3,6ghz
Gigabyte UD5 X 58
Thermalright 120 CPU cooler
The lights from my Lian Li Chassis (Normal amount of Light)
ATI 4870x2
Raptor 150gb new generation

My question is: Will this PSU be able to handle my setup? And will it be good enough in future, if I buy another ATI 4870x2, when they are far low in price.
Then i would have 2x 4870x2.

Im very curious about this. I need to choose between 1000 watt and 1200 watt, and if a 1000 watt can handle it, then ofc. i go for 1000 watt, because its cheaper.

If any other PSU is better/cheaper and can do the same amount of wattage at the same price, feel free to link it.

Thnx alot guys and have a good afternoon

  1. Corsair 750TX should have enough power for your system with 2x 4870X2 in Crossfire mode. ATI CrossFireX™ Certified
    Right now the Corsair 850TX is only $10 more.
  2. what if i put 2x gtx 295 ? gtx 295 and radeon 4870x2 both require a 640 psu. how can u say that a 750 watt can handle two? when 1 need so much

    I didn't say it could. ATI/AMD Certified it could. ATI CrossFireX™ Certified

    Core i7 965 Extreme Edition (Overclocked @ 3.70GHz) / ASUS P6T Deluxe / GTX 295
    850W should be good for 2x GTX 295;


    from TechSpot review
  4. I mean HD 4870x2 use more wattage than a GTX295 in LOAD.

    And watt requirements for a GTX295 is 640 watt, that's what the case and Nvidia says.

    When a HD4870x2 use more watt than a GTX 295, how can u then say that a 750 watt can run 2x of these?

    The first card take the first 640 watt, then there is like 110 watt left for the other one :/?

    I hope you know what i mean :p Im bad at explain things ;p
  5. The paint u just linked shows that a Radeon 4870x2 use 460watt in load.

    then 2x 4870x2 would require at least 920 watt themselves.

    And what about the rest of the system?

    640 watt is the SIZE of PSU they recommend. Not the actual power draw. And that is for the WHOLE PC system not just the video card.

    Shows what the WHOLE PC uses - NOT the video card.
  8. No, but now we see ur paint of power requirements.

    It shows that HD 4870x2 / GTX 295 uses like 450 watt .

    Is the 450 watt for the whole system or the card alone?

    If it is the card alone, then a dual solution will require at least 900 watt for the cards alone right, and then there is the system we have to add too.

    How can u say that a 850watt prolly can run it then? I would say that i 1000 watt will have a hard time, because of the video cards takes 900 watt alone, and then there is a cpu + mobo + hdd that wants power aswell :D

    am I right :p?
  9. 2x GTX 295 with a Core i7 940 processor OC @ 3,709MHz = 675watts

  13. What PSU should I go for?

    In my own opinion BFG should make the best?
