Hello,there i have a 9800GTX+ i wanted to know is my 500w powersupply sufficient enough for the graphics card. Because when i start up and go into windows it tells me my graphics card performance has been decreased due to the fact insufficient power. I know this sounds stupid but i been reading forums and they all tell me that a 450w powersupply is sufficient. pls help me i lost
Make and Model are VERY important. My buddy has an Antec Earthwatt 500w running a PhenomII x2 and an 8800GTX (2 6pin) and it runs just fine. However, an OEM or lowend PSU would never in a million years cut it.
"when i start up and go into windows it tells me my graphics card performance has been decreased due to the fact insufficient power" I have never seen this message.....has anyone else?? Can you please confirm the EXACT phrase that windows displays about your graphics performance. This does not sound right at all. Have you installed the graphics card driver?
Do you have a model number? If it has one 6pin that is a much better indication that it is intended to run an expansion video card.
I thought the 9800GTX+ requires 2 6 pins? If you have one you could use a 4 pin molex to 6 pin adapter. I believe the minumum requirements are 450w w/ 24A combined on the 12V rails. What is your 12V rating?
I suggest getting a 2x 4pin molex to x1 6pin adapter. They come free with some XFX and ZOTAC cards.. not sure if they're given out with other makes. I've had graphics cards in the past (namely 8600GTS) that couldn't use the PSU 6pin, but had to use one of these adapters. I'm pretty sure that would solve your problem.
Thanks guys for all your help i got the addapter but power supply failed after like 30 mins of playing. I guess it was cheap *** any way thanks again
Lets hope that it didn't kill the rest of the system. I am always wondering why people get to be so cheap after making other upgrades or building machines. Antec is a good brand and got two units from them.
