I believe my video card is overheating because of my crappy 400w psu now i just happen to have another psu laying around its a 430w im wondering if i install it will it be better then the one i already am using? A computer guy at a place had said when i asked him if i would be better off using a 430w or a 400 the 400w has 24 pin connector and the 430 only has a 20 pin now the guy states i cant run the 430 because the 400w 24pin gives more power to the board. Now what he doesnt know is my comp came with a 365w psu originally was only a 20 pin and had a celeron d running the 4 pin connector that was next to the cpu wasnt even plugged in. When i added a p4 ht 631 i had plugged in the 4 pin next to the processor because i had seen it plugged in on a 478 genuine p4 so i figured reg p4's needed this extra power plugg. Anyways i added the 400w to replace stock after i picked up a new video card now i had 24 pins connected and a 4 pin on the board next to the chip plugged in. The only thing is the cpu power rating for my newer p4 chip is slighty lower then the celeron d uses less volts too. I dont see why the 430w psu wont work fine. I mean i havent done anything but add a video card . the first one i added was when i had a stock 365w psu that was only a 20pin and the 4 pin next to the chip wasnt plugged in and everything ran smooth. The plugs on the 430w seem to have more nuts put out a couple extra amps. I have recently noticed the connector going from my gfx card to the psu connector looked brown sorta burnt the yellow wire did and that cant be good|||Most motherboards support both 20 and 24 pin power supplies.
I would increase to in the 500 watt range and with 24 pins, there some power supply have 4 pin socket which sides on the end of 20 pin socket. You still have 4 pin 12 volt which plugs in socket near the CPU. Make sure the power supply have correct socket for your video card.
The yellow wire is 12 volts and some reason your video is drawing heavy amounts of amps. Check your video card for blown caps or resistors.|||Your video card would not overheat due to a weak PSU.
But if the PSU is supplying the wrong voltage, or voltage spikes you can see issues like the browning connectors and such.
You should go and purchase a quality PSU that is rated more around 500Watts. The jump from 400 to 430 will not help much unless the 430 Watt PSU is of higher quality.|||If the card is overheating it's due to inadequate cooling. The 430W couldn't hurt but you do need a pin ATX connector for a S775 motherboard.
You didn't mention what card you're using
