Mini-Box picoPSU-80 80 watt Output 12 volt Input DC-DC Power Supply

Used with Intel D2500CCE mini-ITX in an M 350 Universal ITX case with a 5A 12V power brick and it works great with a 2.5" SATA SSD. As mentioned it is only a 20 pin ATX connector not 24 but the extra 4 pins are redundant 3.3V, 5V, 12V1 and ground. This supply won't put out enough current to need the extra pins and it worked fine on the D2500CCE which has a 24 pin connector. The 150W and 160W picoPSU's have 24 pin connectors and these and everything larger than 80W have 12V Aux connectors if you need them. The unit fits in the M350 case with plenty of space to spare for drives mounted above it. Very little heat is generated and it only draws about 2A off the 12V supply with the system above. Total power draw at the plug is about 15W when not idling according to my Kill-A-Watt meter. Works great in this low power application and seems to have plenty of power to spare.

Awesome little PSU. I adapted mine for use inside my Dreamcast as it provides all the necessary voltage rails and is much more efficient and produces less heat than the stock PSU. I removed the edge connector on mine and modified it as such to power the Dreamcast, and it works great, with no noise in the video output at all.

Dump your old PSUs, get this! Would be awesome if there was a case with a hole for the 12VDC connector to go with it, for those of us who use this to replace ancient unreliable flooded with resin original PSUs. (I.e. don't stick it in an existing case)

I gave myself a bit of project for the new year, in revamping my old Dreamcast with a new PSU, fan and GD-Emu drive. This PSU was just the ticket and I felt much more confident buying this than one of the cheaper knock-off picoPSU clones. I used this in combination with a PicoPSU adapter that I picked up on eBay and it made installing this into the Dreamcast a doddle. You will need a good 12V PSU to accompany this, but it's so much smaller and runs cooler than the big Dreamcast PSU board that it replaced. Highly recommended!

It's really hard to calculate your wattage need - my calculations were in the mid/high 60ies so I went for the 80W. For about 2 years this has run a small ITX hypervisor with a small SSD and as much memory as I could put in the very small box. It's worked great but a few times I've found it powered off for no reason what so ever. Last week it gave up powering on. PSU etc. tests just fine outside the motherboard - and everything does turn on for a second or so, so the unit is just too small. I've enjoyed the quiet running for years - if that's important, go for it. But be careful using this for high performance, gaming would be part of that. Add more than just 10-15W buffer to your PSU if you do.
