Power Supply guru please help, tech question not wattage requirement???

Question

I'm confused about two connectors... I have never built with an sli board or sata2 drives. Most important, I've read that sata power connectors only supply 4 wires to the 12pin sata power connector. Which leaves out a 3.3 volt effectively disabling hot swap. I probably won't be swapping anything but does this lack of wires affect the drive in any other way?

Can I hook up 4 SATA drives with only one connector from PSU?

Lastly, can I hook up two SLI cards with only one SLI power connector?

I'm trying to find a good PSU for under 100, I WAS sold on a Kingwin but their site doesn't work to check specs and I won't buy PC parts from a company that can't keep a website up. My build below:

board - Asus P5N-E sli
cpu - CORE 2 DUO E6550 2.33GHZ
ram - PATRIOT 2GB KIT (1GB x 2) PC2-6400 800MHZ
vga - (single)SAPPHIRE Radeon X1950GT 256MB 256-bit GDDR3 PCI Express
hdd - WD Caviar SE16 250GB 7200 RPM SATA 3.0Gb

2 optical and 2 ide hdds in case already.

Okay let me try to clarify this. If the PSU comes with SATA power connectors, then they will do there job, just hook them up to the SATA drive and don't worry about it, and they will be hot swappable. When you come into some problems is when the PSU does not have SATA power connectors, and you have to use a 4-pin molex to SATA adapter, in which case, yes you will lose hot swapability. But any new PSU you buy should come with SATA power connectors, so no worries. You can hook up as many drives as the PSU as SATA connectors, if you exceed that then you will need to use 4-pin molex to SATA adapters.

There is no such thing as an SLI power connector. I believe you might be thinking of PCI Express power connectors. If you have two PCI Express cards that require the special power connector, and only 1 PCI Express power connector, you will once again have to buy an adapter. Just make sure the PSU you buy has plenty of SATA power connectors, and at least 2 PCI-E connectors, and you should have nothing to worry about. Email me if you have further concerns.
