Hello, This is Arijit, i have an old system withe the following config:
i7 920 with cooler master hyper tx3
4 gb corsair 1600 mhz ram
gigabyte ga x58a ud5
1 tb seagate barracuda hdd
zebronics 600 w platinum with 80% stated effeciency
i am looking forward to buy a new gpu, my choices are nvidia gtx 650 and nvidia gtx 650 ti, only these two cards are in my budget and i need a nvidia card for cuda based works too so no option for ati, however i like the nvidia 650 ti very much but i dont know if the psu will support it, i cant upgrade the psu due to budget problems...
the gtx650 ti is a gpu with 110 w power consumption
the gtx650 is a gpu with 64 w power consumption
the psu is with following specs:
+12v 27 amp rail
+5v 30 amp rail
+3.3v 30 amp rail

so my question: will it support the 650 ti without damaging the system?
i am not going for any overclocking of any kind.... in future probably within a year i will upgarde the psu too....

There's not much to do about it, the difference between no GPU and GPU is too great to ignore no matter how low the clock speed goes. I guess I exaggerated a bit, it's not gonna blow anything up like instantly, I was just trying to say that when the power goes out, or when the power coming from the outlet is unstable. That's when it could damage the system because of the PSU, but other than that, it will only shorten the life span of the components within the system because of bad filtering process within the PSU, even that will take sometime for the outcome to show up.

For now, don't worry about getting that GTX 650 Ti. It will work, nothing will blow up, just make sure you turn off the system when not in use to both save electricity...

Nothing personal here, but that's a pretty bad quality PSU. However, it will be able to handle GTX 650 Ti, but I highly recommend a better PSU as bad PSU can also cause safety issue in addition to slowly damaging components.
What is your exact budget for this upgrade? If it's enough, I can try to find a decent PSU and a GPU.

well the budgets till 8500 rs(INR), the gtx650 ti is at around 8300 rs and gtx650 is around 7500 rs... i know the budget is very constricted.... wont it work for may be 6 months?? I will look for a better psu after that...

Well it's going to work for sure, but I can't guarantee 6 months or anything like that. Adding a discrete GPU increases the stress on the PSU, which further enhances the possibility of it causing safety issue and other what not. My point is that, it will work, the wattage and amp is enough to support the GPU. It's just that the PSU isn't good so I'm just concerned for your safety and the component's health.

If you're planning on getting a GPU with this PSU, I advise you to have as little of other components connected to the PSU as possible, such as HDD (just not like 4 HDDs or something)

ok, yes i know now that buying this psu was a bad decision, anyway it has served for 2 years without damaging the system (my luck maybe).
I was just concerned if just starting the system with a 650 ti on it now would blow the psu then and there.. is there any precaution that i can take till then? under-clocking maybe?
Sorry for these questions.. i am a complete novice with psu's.
Yes no more components with this psu even i have decided that...
