Power LED keeps blinking

Hi guys, I use a 350W power supply in my desktop pc. I have 1 case fan, 1 cpu fan, 1 power supply fan, 2 fans for HD, 1 PCI slot fan, 1 CD-RW, 1 DVD-RW and 2 hard-drives. Today I added an NVidia 6600 GT graphics board which has its own fan and requires one of the connecters from the power supply. On the graphics board's manual it says that it requires a minimum of a 350W P/S. Now whenever I turn on my pc, the power LED in the front is always blinking once every second. Could these mean that my P/S is having a hard time supplying power? Or is it due to some other error. Please help.

Thanks in advance
 
i think that your running that computer by the skin of your teeth if your running 2 optical drives, 2 hard drives, a 6600 gt and other parts including the fans you stated, all with a 350 watt, congrats for actually getting that sucker to run :D ....i would deff look into at least a 480 + watt PSU, make sure its a good one too :P
 
I'm having the same problem

i have a 300W power supply...
i have 2 HD's, 1 floppy, 1DVD rom, 1 CDRW and a vid card.. i was using a geforce3 ti-200 vid card that didn't require any power input from my power supply. i just bought a radeon 9800 all in wonder that does require power input, and since then, my pc led light flashes every second. even while i'm playing a video game, it'l glitch every second. is this a power issue?

(correction, i have a 300W power supply, not a 350W). anywayz i just took out one of my 2HDs to see if that would stop the blinking. it didn't. isn't it the same to add power to a new video card and remove a HD that required power? i never had this problem with my old card. could it possibly be something else other than the power supply?

Possibly. If you buy a new PSU and still have the blinking LED you can always return the new PSU.

Quite possibly. What is the rating of it? (i.e., the values in the table that are on the PSU or the make/model of it?)
