I think we need the following internal UPS product:
- Can be fit to 5.25 drive bay (like optical drive).
- You connect PSU to this UPS with standard 24 PIN PC Main connector + other connectors for additional power (P4, Peripheral connectiors, etc.).
- You connect motherboard and peripherals to this UPS with standard 24 PIN PC Main connector + other connectors (P4, Peripheral, SATA etc.)
This way this UPS does not need to very inefficiently generate AC power like in classic UPS but straight DC power for motherboard - just like a laptop battery pack. I think this inefficient battery - DC
- UPS - AC
- power supply - DC
- motherboard conversions is a cause that a heavy UPS can only support a PC for a couple of minutes but light laptop battery can be used for hours.
Anybody heard of a product like this or is in the position to create one?
I'd mostly be interested in something that could hold me over for the 30-60 seconds it takes to save and do a clean shutdown. A bank of supercapacitors could probably hold that much. – AJMansfield – 2015-04-02T23:49:13.300

@blueray This is not the thing. This is just an ordinary 110V/220V AC UPC, but in 5.25" case. I was rather talking about a much more efficient 3.3V/5V/12V DC UPC sitting between the power supply and the motherboard. – Tometzky – 2019-06-18T14:12:51.057
1This sounds like insanity. – Chopper3 – 2012-02-28T11:53:15.510
1@nhinkle - why this is put on hold / closed? This is not a product recommendation question and it won't be obsolete in foreseeable future. This is a more like question "Why everybody does it in this, not optimal, way?" – Tometzky – 2013-07-17T09:25:17.700
