Assuming thats a real 500W PSU.

whats a real 500 w psu and does gtx 1 gb will run games smooth with 1600x900 resolution

 

[4745454b]

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.

so what should i buy to run games smooth at 1600x900

 

[swifty_morgan]

GTX660.

Assuming you have a real 500W PSU thats a fine idea. The 660/7850 should be enough for modern games at that resolution.

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.

Tell us +12v ratings on psu sticker.what cpu you have?

 

[ankk]

24A 26A 22A 0.8A 2.0A
AND I HAVE INTEL I52500K 2ND GENERATION

 

[4745454b]

Yeah, not sure I'd bother with a 7850 or 660. More like 7770 for you.

 

[ankk]

does the 660 will work with asus P8H61-M LX motherboard

 

[ASHISH65]

Yes your motherboard will support any single graphic card.you need to get new power supply.i suggest to get corsair cx 500w.

 

[ankk]

what if i didt buy a new.. does my power unit will run it

 

[ASHISH65]

No under full load your psu will blast and can damage mobo,hard drive.

[ankk]

ok then what should i buy and plss suggest a cheap one but good as gtx will squeze all my money

 

[ASHISH65]

You need minimum corsair cx 500w psu.

 

[ankk]

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!!

should i buy xfx power suppy unit of 600/650 W is it good???

 

[4745454b]

XFX PSUs are good. No worries there. A 660 doesn't need a 600W PSU, a 500W will be more then enough.

 

[ankk]

but i check a wattage calculator in asus website and there your specs and hardware should select andthere it shows recomended 650w

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...
