So what exactly are you using? Post your system specs in the UserCP - http://www.overclock.net/usercp.php . Makes it easier when we know what we are dealing with

For the sake of discussion, assume you have two capable name brand PSUs (say each is 600w-700w) but neither has enough connectors, or maybe enough juice to run all the components (cpu, multi-video cards, drives, etc) that you want power. Is there any fundemental problem with trying out this mod under those circumstances? Maybe use one for 3-way sli & powering fans and the other unit for cpu & drives, for example?

If the PSU is strong enough, it should have all the needed connectors. For the very few devices that you lack connectors for, use molex splitters.

You're right about the molex splitters.

Molex splitters and Molex to PCIE would be cheaper than another PSU, unless of course you already had one laying around.

Even if somebody had a spare PSU, its still going to be better to spend the $2 for a molex splitter (assuming they've already got a good PSU), than risk a fire with dual PSU's.

I've done dual PSU's. I've also done those 5.25" bay GPU PSU's too. Both have ended in fire. It's too risky and shouldn't be done with any hardware that you don't want to lose, period.

I had used it for around 2-3 months, and didn't face a single problem.

Just because you didn't SEE the problem, doesn't mean its not there. Poor voltage regulation and ripple are silent killers of hardware, and WILL slowly kill your parts.

All generic PSUs available here have poor voltage regulation and ripple.
