Hi

I recently bought a new 250 gts to replace my old 9500 gt

when i ran the card,it worked fine.

well,for less graphics hungry games,

when i loaded up prototype,at 1280x1024

2x aa everything on high,my pc just shuts down,and the LED power lights keep blinking and blinking

then my LED fans went5 on and off on and off.

i tried everal methods,i tried to update my drivers.

however it still crashes at prototype.

 

From what i heared around,seems like my psu doesnt have enough jucie.

 

well there was no explosions, or anything.just the shutdown of my pc and the blinking led and fans.

My main question here is,did the blacking out of my pc cause any,or even the slightest damage to my videocard and my hardwares??

i am a little paranoid there,and it is makihng me worry

 

Thank you . :unsure:

You aren't going to need a massive power supply with your system but what you do need is a quality one. The GTX250, no more than 100~125W I would say, so a good quality 400W would do it, a little higher say 500W would be better but good quality.

 

What power supply are you using?

 

Cheers

thanks for the response guys.

my pdc is not very high end overall but somehow the psu doesnt do the job

my system:

core 2 duo e6600 @ stock

2 gb ddr 2 each @ 667 mhz

foxconn ...(forgot the model) mobo

nvidia 250 gts

250 gb sata hdd

samsung writemaster dvd drive.

My psu says 480W but it is those brandless ones so i assume it should be lower than 480w

i think thats about all the major components i have.

If it's a poor quality generic power supply then that could very well be your problem. They tend to quote their power ratings at 25 deg C which is very unrealistic. Your new system will be pushing the power supply, raising it's temperature and its ability to supply full power. I have known some low quality generic power supplies that only give half their rated output power when pushed and this could be your problem.

 

Treat yourself to a good quality 500W power supply, it may or may not be the root of your problem, but you should replace it anyway.

 

Cheers

as long as it is very good quality

 

i ran gtx 275 with HEC 500w and it ran perfectly , it depends on the quality

 

you can get 1000 w generic psu , but it will give lower than 1000

 

my gtx 275 says 550 w psu at minimum , i ran it with 500

 

and by the way , your card does not take that much energy , it will be a gamble if you got the 400 , but with 500 you are in the safe zone

look for brands like OCZ, Pc Power & Cooling, Corsair, Antec

 

With 500w you will be fine. im running the same card, with a quad core phenom II and i got power to spare
