iMac G5 bad capacitors or bad power supply?

I have a G5 iMac (I know, it's really old ) that I need to transfer files from to my new Mac Mini. The problem is that it won't start up. It's had this problem in the past, and all I had to do was open the back up and restart it as per Apple's G5 instructions.

The first LED light stays on, but the second one flickers then shuts off. Lights 3 and 4 do not come on. This has led me to believe that it's a problem with the power supply. However, I noticed that at least two capacitors are definitely bad, and I was wondering if replacing those ( and maybe replacing any more after a thorough check ) would solve my problem.

Or is the power supply the likely culprit?

Thanks,

Will do. Thanks.

Thanks.

I got a similar reply on the PPC forum, and replied to it. I'd do this fix if were easy enough, but I'm not too savvy when it comes to mucking around with computers, and I don't want to screw anything up.
