Hi all,\n\nI'm researching new 500-Watt Quiet PSU's and need a refresher on the\nspecific criterion I should be looking for so the new PSU's like both\nmy motherboards and my (ATX) chassis. It's been four years since I\nlined up parts to hand over to my technician and I apparently didn't\nkeep the notes I originally made when I/they first built these SCSI\nSystems. That -\- and the emergence of new SATA HDD's -\- prompts my\nrequest for help knowing what, specifically, my Supermicro Motherboards\nare capable of handling with some of the newer PSU's and SATA HDD's now\nhitting the market. I'm fairly certain of two statistics on my current\nPSU's -\-\n......they're 115 Volt\n......they contain 12cm fans\n\nHere's a fine example of specs I'm trying to navigate:\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nNexus NX-5000 500-Watt Quiet PSU\n______EPS12V\n______ATX 2.01 FORM FACTOR\n______SLI\n______Dual PCI-Express\n______(6) Molex 4-pin connectors\n______(3) SATA connectors\n______(2) Floppy conectors\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nThe 4-pin Molex power plugs and the (2) floppy power cables are\nfamiliar to me; but are EITHER of my Motherboards -and/or- my type of\nChassis\n1.) "EPS" (eg. EPS 12V) Voltage specific?\n2.) ATX _version number_ (eg. ATX 2.01~) specific?\n3.) "SLI" . . . ? clueless\n4.) "PCI-Express" . . . capable? (I don't even know what this is lol)\n5.) SATA capable?\n\nCurrently I have only ATA and SCSI HDD's; but I'd like these power\nsupplies to be SATA-capable for future expansion purposes. Thank you\nfor any help. See my System Specs below for more detail.\n\nAngel\n\n/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\\nSYSTEM SPECIFICATIONS\n\nI have two Full-Tower (ATX) Systems built with two different SCSI\nSupermicro Motherboards:\nP6DGU <1000 MHz X 2>\nP6DBS <850 MHz X 2>\n\nEach System is a Dual-PIII (Windows 2000 Pro) standalone System.\nEach System is housed in identical 6-Bay Full-Tower (ATX) Chassis.\nEach Chassis currently has installed two 80mm Panaflo™ Quiet Fans.\nThe Chassis Mfg. indicates "room for three 8cm 2nd fans".
