More about what helpp
  1. 2gig GTX660.
  2. Assuming thats a real 500W PSU.
  3. whats a real 500 w psu and does gtx 1 gb will run games smooth with 1600x900 resolution
  4. Some PSUs are labeled as 500W units but are based on old technology and can really only output 300W or 400W. Depending on the rest of your setup you might not have enough power.

    1GB 5450 can't run games at 1600x900. The amount of video memory doesn't mean you can play games. It really depends on all the specs of the chip.
  5. so what should i buy to run games smooth at 1600x900
  6. GTX660.
  7. Assuming you have a real 500W PSU thats a fine idea. The 660/7850 should be enough for modern games at that resolution.
  8. You cant expect to run crysis 3 at hige settings on anything els than a 7970 or gtx 670.
    Even with this cards u still cant max it out, but play at hige settings.
    Now dont go with Sli as your PSU isn't strong enough.

    I would very strongley suggest you wait and save a bit more money and get a 7970 as this has 3gb, and has increadible perforamnce compared to what u pay.
  9. Tell us +12v ratings on psu sticker.what cpu you have?
  10. in stiker it has +3.3v +5v +12v -12v +5vsb
    24A 26A 22A 0.8A 2.0A
    AND I HAVE INTEL I52500K 2ND GENERATION
  11. Yeah, not sure I'd bother with a 7850 or 660. More like 7770 for you.
  12. does the 660 will work with asus P8H61-M LX motherboard
  13. Yes your motherboard will support any single graphic card.you need to get new power supply.i suggest to get corsair cx 500w.
  14. what if i didt buy a new.. does my power unit will run it
  15. No under full load your psu will blast and can damage mobo,hard drive.
  16. ok then what should i buy and plss suggest a cheap one but good as gtx will squeze all my money
  17. You need minimum corsair cx 500w psu.
  18. ok if i put the old psu and run it with the card and it wont damage earlier does it will damage in the future

    No dude like for eg: like you have 400w local psu but it doesnot have real 400w output like it will have 220w or less or more output so your system will run on 220w psu so like your cpu will take 95w+ gpu will 125w+ hd will 20w + others 20w so total pc usage is 260w but your psu is just 220w so it lacking 40w so it will become kaboom or shutdown. There has been cases where psu has taken gpu with it.if you run gtx 660 on that then your $230 gpu can be burnt in one second. So think!!
  20. should i buy xfx power suppy unit of 600/650 W is it good???
  21. XFX PSUs are good. No worries there. A 660 doesn't need a 600W PSU, a 500W will be more then enough.
  22. but i check a wattage calculator in asus website and there your specs and hardware should select andthere it shows recomended 650w
    http://support.asus.com/powersupply.aspx-this was the site link
  23. PSU calculators tend to overstate what you really need. You might also have used the wrong settings. I'm also only guessing as you didn't list system specs. 7850/GTX660 are ~150W cards. Add in a 100W CPU and a 50W for rest of the system and you'll only be using around 300W. A 500w is more then enough. Even a good 450W will do. 650W? Maybe in CF/SLI...
  24. ok thnk you i think i will brought a 650 psu for future use
  25. what should be written in the stiker on psu guyz???i mean the recomendations on 3v,5v,12v etc etc
    what should be the reqd.amps
  26. 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.
  27. should i buy Cooler Master Extreme II 625 Watts PSU it have 2 rails of 12v of 24 amps
    help???
  28. No no do not get cm psu they are not good psus.get corsair,antec,seasonic one.aim for 28a at +12v ratings
  29. 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
  30. dude corsair and seasonic both are much higher price does cooler master will not do??

    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.
  32. 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

    and if i buy a new hdd or any thing like sound card then does 500w can handle it or not
  35. ok then i will buy the seasonic 520 w thats okay or not
  36. if ur looking for a decent performing budget gpu u might also wanna consider in gt 600 series.
  37. no man im gonna buy gtx
  38. 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!
  40. ok then i will buy a seasonic psu which has +5 24A ,+12v on 48A etc and will my mother board will cause any problem............
    my mobo is ASUS P8H61-M LX
  41. No i don't think so? It will work fine as long as you hook up everything right! Meaning right plug for right slot! Are you going to assemble this computer?
  42. Mobo has no relation with psu ratings.just chill

    Duh.

    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.
  44. so is the seasonic 600/520 W a good choice i listed above??
