Is the 350 watt power supply unit ok for EVGA Geforce 6800 graphics card ?
The big issue with a power supply unit rating is the total peak load that it has to deal with, which you calculate by adding all the rated loads of all the parts of your pc that are connected to it, and add yourself an extra 20% for luck. The motherboard, the HDD, the fans, the drives, USB devices, modem, and many more. If you have enough wattage left to accomodate your graphics card then it should be fine.
If in doubt, for the cost it is always better to upgrade your power supply to a larger rated one, rather than overloading a smaller supply or causing low voltage problems with all your peripherals.
Here is the link for your graphics card manual if you need it;
Check page 5 reference the supplemental power adaptor, and check your power supply has an connector for it.
If you want to identify the power consumption ratings for each part of your pc, most will be written on the component somewhere, some in the manual, and some you have to guess by checking similar items ratings online.
If you want help with this please post again and we can certainly try.
Looking at the card, my guess is that a system that can justify such a nice card is likely to be pushing a 350w supply already, I'm guessing what your system could be like and I would put a 600w or more supply in it as soon as i had the cash to do so. post back all the details of your machine and i can figure it out if u like.
This link takes you to some other interesting info about your graphics card.
Mostly a power supply that cannot deal with the demand will inform you by shutting down or committing suicide, although occasionally other components can be damaged by poor power supply, the chance is minimal with many newer items, and it should be worth trying.
The fan performance of a power supply often governs how well it can deal with long periods of high load - give it a proper clean, and remember to check always that it is running. if you want, you can install another fan on the outside (blowing the same way), but unless you power it from a different source then you don't really help much.
Instead of getting a larger power supply, you can just get another (perhaps from an old pc) and only use it to power the graphics card - best left outside the case for overheating reasons.
Hope this all helps :)
