graphic card+power supply
« on: May 30, 2009, 02:13:00 PM »
Would it be ok to power a graphic card to its own power supply?

My graphic card is a GeForce 9800 GT 1GB x16 PCI express
Power supply is 250 watt max the model is ATX-250-12Z .: D. It has to 2 selections on the back 115 and 230

Also it has two connections on the card should i connect both or just on

Sorry this is my first graphic card and thank you for all you help

Ok yes, practical no.

Two reasons: regular computer towers do not have housing for two power supplies and the separate power supply would have to be rigged to operate with a jumper - that means the graphics card would be powered 24/7 regardless if the rest of the computer is powered up or not.

Pointless, the 9800GT eats up some power but I think your over estimating it. Just buy a decent 600 - 700W PSU and you'll have plenty of power for it and the rest of your computer.

The only thing I can think of is these 5.25" bay power supply that could power your video card.  But at $60-$90, just buy a new bigger PSU.

And your 250W will not power that 9800GT.

Just get a bigger power supply. I was using a 300W Sparkle when I threw in a GeForce 9400GT...it was starting to get a hernia. I swapped out the PSU with a Corsair 650W. This PSU can definitely handle a GeForce 9800GT. On my 9400 box it clearly states that the minimum wattage needs to be at least 350W. Usually if I see those type of minimum numbers I will at least opt for 100 Watts or more than it calls out for.

OK so you want to hook up your VC to a PS you can buy online for less then $10? It's not just watts its the quality of the power itself. A cheap PS that puts out "spikey" power is just going to kill your VC a lot sooner.

Seriously; how are you planning to get both PSU's connected to the power switch?  How is the motherboard going to regulate votages from 2 PSUs?  The answer is no.

115 vs 230 on the back?  If you live in the US select 115.  If you live in Europe select 230.  It's the input voltage.

The 9800 GT only has one connector; a six pin and your PSU needs to have one to plug into it.  The other "connection" you see is for an SLI bridge.

I'd tell you to just go get a 450W or larger power supply but we don't even know what kind of machine you have.  If it's a Dell or something you can't buy just any PSU.

BTW, if you try to run that card with your current PSU you will fry some combination of the PSU, motherboard and/or video card.

Some dells can now take any atx power supply.  I have an inpsiron from 07 that supposedly will accept anyof them.  I also think PP&C offers PS upgrades taylored for dell.  Check the Dell forums.

Look for the Lian Li PC-A10 case which can house two PSUs.

 Newegg.com has a wattage calculator. Click on powersupplies/powersupplies. 500 watts is about the minimum anymore. 115 is the norm for most apps.  The days of picking any ole PSU and throwing in your computer are gone. Corsair, Thermaltake are good brands.

No the larger power the better.
