TX650 enough or will i need to upgrade?

post #1 of 8
Thread Starter 
Itching to go for a rasa 750 kit and add another GPU.

My current rig is in my sig but the finished upgrade would be:

2x 6950 (unlocked)
Rasa 240 kit (750 pump)
1100t @ 4ghz
1x OCZ Vertex 2E 60gb
1x 500GB WD Caviar Green
1x DVDRW
1x Fan controller
5x120mm fans
1x 140mm

Thinking I am cutting it a little bit fine, would 750 be enough?

I'm always on a budget. Thanks for the advice chaps.

Usually I would say 650 is fine for that crossfire setup, but you have a pump in there aswell. You would have no headroom for overclocking at all.

750w would be perfect, IMO although, not saying its not doable on 650w

Pump its self isn't too bad on power. But everything added up won't leave you with a lot of headspace at 650 W

My computer with same mobo, same cards (only at 840/1325 so far due to nonflashed bios), same SSD, same PSU, pump (655), DVDRW, fan controller, 5 1500rpm fans, and 955 overclocked/volted to 4.35 @ 1.52 volts with overclocked/volted NB never pulls more than 500 watts while gaming or running 3Dmark11 (based on my kill a watt) I would say you are definately fine! thuban cant use THAT much more power than deneb! thumb.gif hope this helps! smile.gif

175 for you CPU OC'd and 400 watts for both your 6950s @ 6970 speeds = 575

Legit reviews power consumption test, ran with 2 6970s and i7 970 (six core) pulled 596 watts (for the whole system under full load)

I think you could do it. But like others have said you wouldn't have much room for overclocking. The TX650 does have a really solid single rail 12V though. If you are on a budget and are just unlocking the cards and not overclocking them, you should be good. And that PSU should be good for future use too. I don't know what CrossFire 6970's wouldn't be able to handle game wise. My CF 5850's at stock can even play BF3 @ Ultra 1920x1080. If you don't already have the PSU you should get it.
