External Power Suppy For Graphics Card

11/14/2011 2:47 AM

Dear all,

My PC has 8600GTS graphics card installed on intel DP35DP motherboard + Core2Quad Q6600 processor powered by 400W power supply. Now i need to replae this old graphics card with geforce GTC550ti. Problem is that this new card requires 400W supply with 24Ampers on its +12V rail(i saw in the datasheet) and my existing supply doesnot have this capability. What sholud I do know?. Can I power this new grapics card with a new external powersupply?. if yes than should i need to have common ground for cpu body and new powersuppy?. Or if simply use the same old suppy for this card, no damage will be happen to PC?....Waiting for your answer.

The PCI Express 2.0 is backwards compatible with the PCI x16 1.0 and 1.1 slot motherboards. However, PCI-e 2.0 cards on 1.1 and 1.0 motherboards will not be able to run at their max capacity.

The Silencer 610 EPS12V should work for you...

After looking at the spec sheet on your motherboard, 610 EPS12V is not compatible....I cannot find any ATX in the power required...Time for a new motherboard..

The correct solution is to replace the PC power supply with one that can do the job. I don't know about places to purchase them in your location, but here in the USA, a couple of places to buy would be:

www.tigerdirect.com

www.newegg.com

www.CDW.com

Perhaps you have some local places that sell PC power supplies? I know that you can get a new PC supply around here for less than $50 that would work for you.

The simplest and safest option is to replace your existing power supply with a larger one.

Computer power supplies are fairly cheap and trying to run two power supplies is asking for trouble and may even cause graphics card, power supply or motherboard damage.

I agree with the other posts that you should replace your power supply. Go through the reviews at newegg.com and buy the one that fits your budget and has the highest satifaction rate.

Think of using higher power supply instead.

I think upto +800W are available, some may need extra cooler but using two PSUs is not recommended anyway.

Before you plug in a higher wattage power supply ensure that your particular motherboard can handle the increased power requirements for the new graphics card. If the power handling circuits on the motherboard are not rated for the increased current flow, you may be adding the cost of a new board to your list.

You should also take into account the added cooling requirements for the more powerful graphics card. Ensure that your chassis cooling arrangement can move enough air to keep the new card cooled.

You need to replace your power supply. It is very simple and should not cost you more than $50-$100. Also check your motherboard specs and cooling issues as stated above.

Your current PSU is undersized for your system, upgrade PSU to 600 Watt at minimum
