i have just purchased a bfg 8800gtsoc for my computer. but after 10 min of playing a game or watching a movie, the computer completely shuts off. it says i need a 12v current rating of 28A or more for the card. i bought the power supply about a year and a half ago. extreme power 600w from cool master. it has a +3.3v 28A, +5V 30A, +12V1 18A, +12V2 18A, -5V .8A, -12V .8A, 5Vsb 2.0A. I dont know what it means but is my card getting enough juice from the supply and its shutting of the computer or could it be something else? thanx
 
Ive also left the computer on without anything running for about 2 hours and it didnt shut itself off. and if it is the psu, then are there any suggestions to what psu to buy? ive been looking around on newegg but the numbers just doesnt make sense to me.
 
check out the NZXT PRC-850 Power Supply vs TruePower Quattro 850W


people suggest me to buy truepower quattro for 8800gts and even SLI. Also, they told me it is future proof. well, i guess this is the PSU for you too have fun !!
 
cool thanks.
is my psu too low for my card though? i dont under stand what the 12v 28A is and how to determine what psu has enough power and what not. i looked at the 101 thread but it doesnt explain it

yeah i don't really get that part too. i suppose the higher the number next to A is the more of the power will output. now, people are looking for something like 12v 30A or greater. like 12v 33A something like that.... but i am sorry i don't really get this whole thing..
 
The "A" Stands for amperes, or amps. This is the measurement of current flowing through an electric circuit. This is more important than watts most of the time, and the less current through the circuit, the less the power. Also, the 12v is what is know as the 12 volt rail. This is what supplies the power to the graphics card.
The rating on your PSU seems to be a little low, considering you have 2 12v rails. The combined amps may be too low, especially under the temperatures and conditions you may running it under. But that's just my opinion, I'd wait for someone a little more knowledgable to lead you in the right track.
 
That PSU provides a net +12V@30A, which should be sufficient for your system, although there's always the possibility you have a defective unit. With some sort of load, run a program like Speedfan, which will tell you the actual voltages on each rail. It's not always accurate, but it will give you some idea of whether the voltages are dropping dangerously low.
 
k thanks for the input, actually i just got a message when i booted up saying that my psu fan is down now. im guessing the psu is done lol.
 
well, i get that before but after i check the fan is still running. it is just that my motherboard is incompatible with the PSU's FAN thats all. all you got to do is just go to bios and just press save and exit.
