Galaxy gt 240 512 mb ddr3 on a bestec 250w. Plausible?

[Cashb005]

Just want to know if it will work. The dangers of trying it and how long will it work.

I wouldn't. Theoraticly it's possible but the chance of killing the psu is to great i think. Also when your psu goes it sometimes can take your system with it.

250 is vendor rated power, probably of a cheap power supply. It probably puts out 200 in the PC in normal use, if that. Add in all the power the PC alone takes, I would not run that card in your computer.

What im actually doing is putting the gt240 into the PCI-E slot which in turn will override the integrated card already on the system. From what I have researched the card pulls 69 watts and the PCI-E slot has a designated power of 75 watts.

 

[GreenDutchAlien]

Yeah, and your system takes 100 - 125W (?) so if hangthe9 is right with the 200W ( and he probably is ) it would come down to 190-200W system power draw, the max of the psu, again ; i wouldn't.

Your Bestec is possibly one of the most fecal PSU-shaped objects ever made: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=154

The PCIe slot does not provide the power, the power comes from your power supply. You're not adding 75 + 250 from your PSU to get the power you are outputing. What that 75 watt means is that a card can need up to 75 watts of power and be able to run just off the PCIe slot power without needing a secondary power plug. I don't know if you are thinking that you'll be safe just because that card can run without a secondary plug, but it's not a good idea.

You're free to try it though, it's your system. I'd only give it a 20% chance of being stable though, at best you would probably get random shut-downs, at worse your video card and motherboard will die after a few of those. Up to you if you want to risk it. A decent 300+ watt power supply can be had for abut $30, you may be safer with that. And a 240 may not be the best card pick. If you have a decent dual-core computer, get a Radeon 6770 or a 5770 (same card really) and a 400 watt PSU, should be around $120 for both if you look for some sales.

If you try it make sure you film it. Filming the magic smoke escaping would make a nice you-tube movie.

Modern PSU will refuse to start. Thats all.

But that PSU just is not powerful to feed your gear.

Well I went ahead and tried it. Its been 8 hours with no shutdowns. The card has maxed at 84% usage on a full load and the max temperature has been 50 degrees Celsius and idles at 34 degrees Celsius. Currently running 80% fan speed and all other components are running cool. So far so good. For all who said it can not be done. Everything is running stable and I have tried to stress it out.
