Default Newbie POWER SUPPLY questions related to my MOBO w/FULL-TOWER (ATX) Chassis . . .

Hi all,

I'm researching new 500-Watt Quiet PSU's and need a refresher on the
specific criterion I should be looking for so the new PSU's like both
my motherboards and my (ATX) chassis. It's been four years since I
lined up parts to hand over to my technician and I apparently didn't
keep the notes I originally made when I/they first built these SCSI
Systems. That -- and the emergence of new SATA HDD's -- prompts my
request for help knowing what, specifically, my Supermicro Motherboards
are capable of handling with some of the newer PSU's and SATA HDD's now
hitting the market. I'm fairly certain of two statistics on my current
PSU's --
..=2E...they're 115 Volt
..=2E...they contain 12cm fans

Here's a fine example of specs I'm trying to navigate:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Nexus NX-5000 500-Watt Quiet PSU
______EPS12V
______ATX 2.01 FORM FACTOR
______SLI
______Dual PCI-Express
______(6) Molex 4-pin connectors
______(3) SATA connectors
______(2) Floppy conectors
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -

The 4-pin Molex power plugs and the (2) floppy power cables are
familiar to me; but are EITHER of my Motherboards -and/or- my type of
Chassis
1=2E) "EPS" (eg. EPS 12V) Voltage specific?
2=2E) ATX _version number_ (eg. ATX 2.01~) specific?
3=2E) "SLI" . . . ? clueless
4=2E) "PCI-Express" . . . capable? (I don't even know what this is lol)
5=2E) SATA capable?

Currently I have only ATA and SCSI HDD's; but I'd like these power
supplies to be SATA-capable for future expansion purposes. Thank you
for any help. See my System Specs below for more detail.

SYSTEM SPECIFICATIONS

I have two Full-Tower (ATX) Systems built with two different SCSI
Supermicro Motherboards:
P6DGU 1000 MHz X 2
P6DBS 850 MHz X 2

Each System is a Dual-PIII (Windows 2000 Pro) standalone System.
Each System is housed in identical 6-Bay Full-Tower (ATX) Chassis.
Each Chassis currently has installed two 80mm Panaflo=99 Quiet Fans.
The Chassis Mfg. indicates "room for three 8cm 2nd fans".
