i have a 500w power unit and what grafic card should i buy i have a 1600x900 screen resolution. i want to play games at high and ultra like bf3,crysis3 etc
my choices are gtx 660,ati 7850,gtx 650 and the card at that price range plss help to choose and should i buy 1 gb or 2gb with this resolution helppppp 😉
 
Just make sure that the column below +12V has 24A or higher. To run a gtx 660 you need 24amps current on a single rail i.e column below +12v must be 24a. If you want to overclock then get a higher rated psu. I would recommend seasonic s12 ii 520w psu as it has 40amps current under a single 12volt rail. Google it to know more no the product. It is priced a bit more than corsair cx500w.
 
Go for seasonic. They have better ampereage try 620w. Most modern systems require power from 12v rail. My brother user it and not reported any issue. He uses seasonic 620w psu. I am willing to buy a 520w

Wrong. 24A * 12V = 288W. The GTX660 doesn't use 288W. I think the GTX660 is rated for 150W and the 660TI is around 180W. You don't need 650W PSUs to run a GTX660. A good 450W unit will run it.

Here is a review of the "extreme 2" 475W unit.

Uh, not good. If the 625 is similar you don't want it. Any other PSUs where you are that you can afford? Again it doesn't need to be a 600+ unit, look at the better 500W units.
 
see my specs are i52500k, 2 hdd(1 is 80 gb and another 1 is 500gb ),1 cd/dvd/rw drive
and going to buy a asus 660ti top edition
how much power psu should i get and if i wanna get another hdd then how much power will it consume
ur opinions??
whats best psu in +12v which give a resonable amps

what should be better??
 
660 TI is a good choice with a little overclocking its performs very close to the 670.

Though Best bang for buck is definitily the 7970 radeon.
So if you can ither wait and save some more money and get this card you'd be set for quite sometime.
 


it is NOT that simple my friend! A 12v is not used only for gfx card it is also used to power other things! Even recommended psu for gtx 660 is 450w with minimum 24A on a single rail. And not just any 450w psu would run it. If you don't believe me check its specs in original website!

Duh.

Even recommended psu for gtx 660 is 450w with minimum 24A on a single rail.

First thats stupid/dumb. The first (?) ATX spec that allowed multiple rails capped each rail at 18A. Most stay there or go up as high as 22A. While not impossible most multi rail 12V rails aren't 24A. Second, you don't need that much power from one rail. You'll have no issues if some of the power comes from more then one rail. A card has no issues taking 75W from the motherboard while taking the rest of what it needs from another rail. They do it all the time. Finally third, most "recommendations" you'll see are companies trying to "CYA" or they are worried you are going to use a POS like a Diablotek PSU. So they overstate what you really need.

If you have a 150W GPU (GTX660) and a 125W CPU (FX 8350) your power draw is ~325W. Any PSU that can output that power on its 12V rail(s) will work. You'll obviously want a bit more. Most good 500W PSUs can do 408W+ so they are fine. But there are new gold rated 450W units that will handle this load with ease.
