my psu will support gtx 750

[xachinj4497]

Currently i am using ge force 210 1 gb ddr3 which needs 300 watts of psu
But i have only 200 watts
It is running well since 1 year
But i am going purchase gtx 750 1 gb gddr5 whuch also requies 300 watts psu
So i want to asj it will run good on my psu

No... You need 300.

The 750 non ti is about 20-30 watts more under load from the specs Nvidia lists.

200 watts is a bit of a light weight, but it depends on how much power is on the 12 volt rail and what else is in the system.

I personally have been running a 300 watt(22 amps @ 12 volts) in a system with a GTX 650ti(used to have a 5770) for a while without any issues.

I have pentium g2010 which is 55 w

Under some loads both video cards and cpus can pass the TDP numbers, but that is another story. Lucky enough most users never push a cpu to its max anyway.

How many amps does this power supply have on the 12 volt rail?

Intex
Model -Classic 450
Ac input- 220v 4a/50hz
Dc input- +5v_29a
,+12v_18a,+3.3v_30a,-12v_0.5a,+5vsb_2a
(3.3v nd 5v = 85w max)
Total output shall not continuously exceed 200w
It is all written on my psu label
How much it is?
And it'll be able to run gtx 750
With my pentium g2010 dual core 2.8 ghz
Thnks

Because that is a older and rather cheap power supply it does not have a continuous rating like many newer units(thus the 450 in the name seems to indicate that it can do 450 across the rails for a VERY short time). Newer units are rating in continuous power.

This kind of makes most of the other ratings less useful. So it can deliver 216 watts @ 12 volts for a very short period of time, but you also have to take in the other rails as well.

Now assuming if your system is power friendly enough(the cpu and video card are quite power friendly) you should be able to pull it off. My only fear in this case is that the cheaper/old power supply may just give in at a random time taking out parts with it. I would recommend getting something a bit better just to have the extra piece of mind when using the system.

My current media center has to work VERY hard to break 180 watts @ the wall, but everything was picked for lower power and even I have some extra overhead in the power supply just to be safe.

Sorry for late reply
As you are saying ill be able to pull it off
I hav only fear about damage
That full utilization (may be over) will damage my system
It can?

Since it is a no-name power supply, it is hard to give you a yes or no.

It could last for years or could catch fire next week.
