Are you SURE you have the 20 Pin + the 4 Pin + the ATX connector? Just plug in those three and see if it boots. Don't connect anything else until you have successfully booted to the BIOS screen with just those connectors.
If you want to test the power supply, take a paper clip and connect the Green wire in the 20 pin connector to one of the adjacent black wires. If your hair stands on end then you are good. (Ok, your hair should be fine, just the fan will spin - there is only ONE green wire, and both black ones next to it are grounds).
Other than that, I have not seen any recent computer that does not use standard power connectors, so if it still doesn't work, give us more information about which PC you have..

Did that earlier - no change. I have swapped rails, changed the power
connector to the SATA connector directly from the PSU (replaced the
Molex-SATA converter). Zip. No beeps. No boot splash ... CPU fan
spins. I even swapped the 530w PSU thinking the 1st one was bad - nope!
I have used the 4-pin connector in conjunction with the 20-pin ATX
connector (in addition to the ATX CPU connector) and without it.
I don't see any HDD power lights directly. What I saw earlier was a
reflection from the light in the PSU. I should have caught the color
Weird thing is - I can swap the 250w PSU (using the Molex connector for
the HDD and voila! It boots....

I intended on installing one thing at a time & testing. So the new
video card is in the box. I am only using the integrated video.
I wonder ... are there BIOS settings that can/should be changed???
Hmmm... back to swapping the 250w in ....
Ah this is fun ....
