Okay...so I bought a power supply big enough to handle my graphics card. But when I got it home - and tried to install it; I found out that it is a 20 pin; and my motherboard is an ATX 24 pin. My old power supply was a 24 pin as well. I am still able to fit the 20 pin power connector into the 24 pin slot; but then a message comes up when I start my computer stating 'It is recommended that you disconnect your 20 pin connector - and replace it with a 24 pin connector. It doesn't say it's mandatory - but recommended. Well - that got my shaking in my boots - and I didn't want to hit the 'any-key' to see if something would get fried or not. I went up to Best Buy and Comp Usa, looking for a 20 to 24 pin converter, but to no avail. I talked to a gentlemen at the geek squad - and he told me that my motherboard could blow - but it might work. I really don't want to drop an extra 20-30 dollars on a newer 24 pin power supply, but I might if I have to. Do you guys think that if I just press the any key - and let it go on - that I would have a good chance of my computer being okay, and not frying my motherboard, hard drives, etc. All help is greatly appreciated, thank you.
