AGP 7800 BFG - Power Supply Question

musictoad · October 12th, 2006, 11:20 PM

Hi ,
I would like to know whether it is possible for a power supply to be a factor in over all PC performance and mainly if there would be a possiblity that there would be no full performance pushed out by the graphics card?
i.e. will the graphics performance perhaps be slugish, causing drop or skippnig of frames , at various moments ?

AMD 2500+ Barton
K7N2 Delta Series
512 Kingston 3-3-2-5
4 Drives : Maxtor 160gb , Seagate 80gb, Seagate 250gb, LG-DVDRW H...
Sound Blaster 24 bit Live 7.1
XP Pro SP2
LG Monitor 85 hz at 1024x768 2003 model crt
Power Supply 300Watt

300w most likely won't be able to power a 7800, it would cause your program to freeze up.

Hi,

Okay, well I am running fine at the moment , thing is i do get beeps from my Graphics Card speaker when i am in certain screeens during gaming, and also when i encode using virtual dub, most likely because cpu power is being chowed up big time and therefore the power is less for the card.

I can confirm the beep are from the GFX Card and not the Mobo because i have unplugged my Mobo Spkr.

Anyways, can you maybe tell me more then....now that you know i am not freezing up and stuff...

BAsically my plan is to buy a 500 watt Eurocase power supply. So that is what I should have mentioned in the first place.

Question still remains if you like to give me explination, please.

Thanks again,
ItC

If your computer isn't getting enough power there should be many inconsistencies in the way it runs, but particularly when it's working hard.

I'd highly reccomend not getting that PSU. I've never heard of that name, and it sounds generic, which isnt good w/ power supplies. Look at this thread for more info on PSUs:

Do you have a specific site you want to order from?

If ur in the US, newegg.com is proly the best site to order from. If you want, people here could give you a few suggestions at the best performers for least cost.

EDIT: Its sort of dangerous what you are doing, running a 7800, and multiple drives on a 300Watt PSU. Theres chance that PSU could die taking along a few of your other components.
