Okay I figured out that I am going to buy a 4850 but I was wondering whether or not i need a new PSU. My rig is in my sig (ooo that rhymes) :D 

More about : 4850 600w psu

That psu will be just fine. Enjoy your new 4850 ;)

For sure.
I'm using a 4850 and e7200 with a 450 watt Corsair PSU.

Don't just look for high wattage on a PSU.

You got plenty of power with that PSU.

at 110 watts per card(Full load, most times less), you can run 4(3 would be safer) of those and a decent cpu(dual core 45nm to save power) with 2 hard drives and a dvd drive. Would be a stretch but with a good psu it would run. so 2 is not the max.

No, you are all wrong because
4+8+5+0 > 6 so he needs greater than 1700w PSU.

lol

The 600 is fine.

I hate to point out the obvious, but he can't run more than one (at least not in CrossFire) because he has a nVidia chipset. Of course from a simply power point of view, he should be able to run two.

Also you can't simply go off the wattage of a PSU to determine whether or not a particular graphics card will run, it's the current rating of the 12V supply.

True, most modern power supplies can send almost all there power into there 12 volt rails. This will cut the 5 and 3.3, but since the draw on those lines is so low its is not an issue.

My point was there is more then enough power for one 4850

I still use the infamous SmartPower 450 with a 8800GTX

If you can read, which I hope you can. The box says min 450W psu for single 4850. You have a 600W psu. You should probly get a 1.3 KW psu just to be sure.

EDIT. Thermaltake offers a 1500W PSU. 1.5KW. I would highly suggest you get that. Better to be sure than not at all. A 4850 draws lots of power.

How many amps do I need on the 12v rail?
My psu currently has 18

@oneshot: Im guessing you work for thermaltake and you get a commission :D 

*EDIT*: I forgot to mention I have 4 12v rails at 18amps each ( i made it seem like I only had one :D )

If you only have 18 amps on the 12v+ rail, that sounds weak to me.

LOL, you would think so, but, 450 recommended could be a lie..a big lie..so by gettin a 1.5 KW PSU I can be sure I don't like lies. I have a 650W CM Real Power with my 4850. I like to mess around. I've been thinking of getting two 1.5 kw's, Tape/glue one psu to the side of the case then I can turn everything off in my APT so I KNOW, my 4850 will undoubtedly work. I like to be sure. :ange:

YOU CAN HAVE 15 CARDS.


600 is fine, yes.

With 4800 heating problem, do not put more than ONE card or your rig will be a melted choclate

So much BS in this thread. The xml hack will get the temps down to the 50s on two 4850s. The 4850 is both power-efficient and potentially cool-running - if the fan is set to run at 50% or more duty cycle.

As for power supply wattage, when my Antec Quattro 850 failed (Manufacturing defect) I ran two overclocked HD 4850s, six drives, water cooling, and an overclocked Q6600 on an Asus Maximus with a 550 watt Silverstone Zeus supply for a week with no problems. The replacement Quattro is now back in the system and runs cool with the fan not audible during gaming on this rig.

oneshot are you mentally retarded. unless you're running 10 harddrives, three GTX280's and a phase change cooling system you dont even need a one thousand watt psu... WTF

If you read that and couldn't pick out the loads of sarcasm, I think you might be the one to have your mental capabilities checked out.
