Power supply problems. Need a new/used card 6870R3860AB

Firstly, you need to have a power supply that meets the power (Watts) and current (Amps) of your card. Check your video card's documentation to verify this, and look for a sticker on your power supply to give you more information about your power supply's Wattage and Amperage ratings.
Next, if your video card needs additional power (it will have a molex 4 pin (like a floppy drive uses), or a 4 or 6 pin PCI Express Power plug. In case your power supply does not provide you with this type of power connector, many video cards include a 4 pin Molex to PCIE adapter. Again, make sure you meet the power requirements for your card, or it will likely die prematurely due to under-current conditions.
If you are using an adapter, plug a hard drive or CD-ROM drive power connector in on one side and to the video card on the other.
IF your power supply provides the correct power connector, use that one side goes to the power supply, and the other to the video card.
(It's less hinky that way, and I think it gets it off the same circuit with the other devices.
Good Luck!

You do need to install the drivers before using your new card, but that would only effect the display if you didn't. If the computer is actually shutting down, then I think your power supply might be the problem. Check your card's manual to see what the minimum power input is. Then compare that to what your current power supply's output is. These new cards draw a lot of power and if your power supply can't handle it, the computer will shut down. If it does turn out you need a more powerful power supply, you can find them online. It's a fairly easy change to make. Hope this helps!

There are two types of video cards, Ones which power themselves for the Slot and other high end ones need to be powered from the supply. Most video cards are provided with a cable like this one. You will need this cable in order to properly connect your video card to the power supply.

Hope this solves your problem.

1 or 2 extra hdds and ram does not require much extra power and your coolmaster should do the job. But if you intend to use a newer graphic card you should check the requirenments for wattage at your new card manufacturer product specification webpage. I am pretty sure that almost all newer graphic cards require at least 500 watt to run without problem. My advise is to buy at least a 550 watt psu although i don't know what is your hardware. Try to post your hardware specs and calculate for each component (cpu wattage+graphics wattage +etc) your power supply need to be over 50 wattage. Hope that helped!

Hello,
If you are really sure that your monitor is working, then you would probably have to change your graphics card with a working one to see the results. That should solve your problem. If this does not solve your problem, then we are not dealing with a display problem here. In this case, you may have to check your memory.

All the best.

Just check the Power Supply has the minimum wattage supply required for the Graphics card (The power supply should have more than the minimum after all your whole cpu unit is runnin on that).Try n change to see if that works.
Try connecting a different or switching the chords/power port from the power supply to the graphics card...u can try wiggling the cables also.
If you have an onboard graphics card,try disabling that from the BIOS.It would be Video/AGP/PCI something like that.
Also check if the slot that is used for the Graphics card is not burnt or damaged. If the problem still persists you have to contact the customer care of the Graphics card or the motherboard.Just to be sure where the problem is you can try using another graphics card on your pc or you can check your graphics card on some other pc,by this you'll come to know where the problem is. Hope it helped.

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.
Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

A four pin splitter you should be able to obtain for any computer supply store. Hopefuly your power supply with have enought wattage to supply this new video card.

you wont damage anything but get at least a 450-500w power supply. Nothing should be damaged

hope this helps

Unless you are working with 3D models your gains in upgrading your VGA card is minimal as photoshop is knowns to be more dependent on the size of memory, speed of memory installed on your machines as well as the speed of the hard disk. The processing power of the CPU also can be an important factor than the graphic card.

However if you are set on going for a new graphic card, I would advise you that you get a new card such as the 8600GT or the ATI 3850 (Similar in price but faster than the 8600GT and 7600GT and uses the same or less amount of watts!, and also does not need a the 6pin connector for additional power).

Going back to your power issue, you have not stated your power supply's wattage or amperage, or if the power supply is generic or branded all which influence the decision to get a new power supply. However if you have a power supply that provides a true 300W you should be fine to run any of the cards stated above.

With regard to the bus issue, if you have a PCI-Express bus you should be fine in getting any of the new cards, but if you have AGP you will be more limited, though i know there are 7600GT (old stock) which are for the AGP slot, and only AMD (ATI) released there R2600 range for the AGP slot.

Hope the information is useful :)
