I think I should also quote this point:
She?! Just because I have an avatar of Lulu (the best champion in LoL) does not make me female in person. >_>

Ahh, sorry about that. This friend of mine had that similar avatar (the background wasn't transparent, I believe. Don't feel like checking atm) happens to be a female, so I guess I was thing of her when referring to your post... lol Especially considering how I was chatting with her minutes prior to my post.

Thanks for the opinions on this guys. I am actually trying to get numbers on failure rates on multiple and single rails designs. I don't think any exist. Their failure rates must be the same. I did check the PSU list, it is a combination of single and mutiple rail designs. Thanks .thumb.gif

That's because the number of rails has nothing to do with the quality or design of the DC output stage of the powersupply.

Yep. Multi-rails really only help in the extremely rare occasion that a short occurs but SCP doesn't kick in.

And the bigger your PSU, the more likely SCP won't kick in when something goes awry - I've seen a floppy connector (off of a molex adapter) burn up, and not kick off SCP because there was too much resistance in the wires themselves - FYI the floppy wires were glowing orange when it happened. That was with a 600W psu.
