Windows 7: Running a 9600gt on 250w power supply.

Running a 9600gt on 250w power supply.

Hello and good morning to you all. I have been running my computer on a antec 5oow psu for a while now but since about two weeks ago it had been shutting down randomly. After many days trying to determine what was at fault I discovered that my psu had taken a turn for the worse and was just cutting it dead several times a day. So what I have done is reverted back to the original psu which came with the computer when I bought it, which is only three months old. So what's the problem I hear you ask. Well the problem is this, right now (touch wood) I do not have one, but I am running a 9600gt on 250 watts and the manufacturer states it must be at least 450w. I have been running it for three days now and have noticed no drawbacks at all. My idle temp is 49c and my full temp is 70-2. I do plan on getting a new one but do you think I will suffer any adverse effects. In all honesty I did not think it would even power it up but like I say it has actually quite flawless in it's approach to gaming. Any feed back would be welcome. Thanks.

I think the whole massive power supply thing is just another way for psu builders to sell you a high spec PSU you don't need.

If you go to an online power needs calculator, you'll probably be surprised about how little your system is actually using. Of course a little leeway is always a good idea. I run my 9600gt on a 400w supply with absolutely no issues.

I was thinking the same myself Jac that it's all a ploy to get you to invest more. By the way seeing as you have same card what temps does run at. I have only just bought this card so I am still familiarising myself with it. Are my temps about right. Thanks.

Those temps look fine to me. I don't normally have a temp sensor running so only have temperatures from when I have experimented with raising frequencies with nvidia control panel.

My idle temps are around 59 degrees - rising to circa 70 when clocked and running a game.

Thanks mate. My temps were higher with 9500gs but didn't know what to expect from this and although I had googled there are different temps because of the different brands.

Edit. Iv'e just been to an on-line power calc and it reckons I need a max of 240w with all the set up I have.

That's exactly what I was going to do any way. I was more concerned with the immediate future as I wont be able to get one for a couple of day's until it is delivered. Thanks antway

My 8800GTX just died and I picked up a 9600GT and according to the WEI scores it is very close to the 8800 GTX. The GTX got 5.9 6.0 5.9 in the graphics section and the 9600GT got 5.9 5.9 5.9. Damn, the $460 price difference seems alot for a .1 gain in gaming graphics.
Which is to say the 9600GT 512 seems to be a very nice reasonably priced video card.

I used eXtreme Outer Vision - eXtreme tools for computer enthusiasts and with my components, as listed to the left, I need 649W on a 90% load (this is including my OC to 3.21 GHz). I currently have a 780W PSU, so I am pretty good.

the overall ''wattage'' is nowhere near as important as the Amps... if there's not enough Amps it can seriously strain the card....

i think they ''recommend'' 28A on the 12v for the 9600, but you'll easily run it on 18A, anything below that may cause problems, or a lack of performance...

just remember a GFX card is better equipped to deal with too much power than too little...due to the fact it can regulate its power intake, but if its not getting enough there's nothing the card can do but go hungry......

i bet there's not even a dedicated 6pin on the 250w..??, i'd buy another one if i were you.

b/c a working system can fool you into a false sense of security, depending what peripherals you have, that PSU may be slowly melting... & there is a REAL possibility that (if/when) it pops the surge could take out a good few components with it.....

just my penny's worth.....
