Hi. I'm relatively new to SFF building and PC building in general. I bought a 250w pico psu and it has been working well powering my i5 7400 and 2x8gb of ddr4 2133 ram. I was using a 12v 10a portable charger with a lot of adapters to plug into the pico psu (kinda a bad solution). I just bought a 1050 ti low profile and now I need a 12v AC to DC adapter for my pico psu like a laptop charger. All the ac to dc converters I have seen suggested on the forums either had broken links or they where the wrong plug like the xbox 360 adapter:

This is the the power cord on my pico psu (left) and a 230w 19.5v charger that doesn't fit and has the wrong voltage from my laptop(right):

Is there any 12v power adapters that can fit my pico psu around 200-250 watts? Thanks in advance.

what about replacing your 250W DC-DC, with a 500W DC-DC ??

i've gone brickless so i don't need mine anymore.

Can you get 500w dc to dc converters? The highest I’ve found was the hdplex 400w that’s always out of stock. I don’t have enough room to fit a mini itx ac to dc-atx psu in the build. I don’t really need more than 250w anyways as I won’t be overclocking.

it is 500W, because i've tested it.

fits in a 5L computer case, with no problem.

The issue is that 10A is the rated limit on 5.5/2.5mm barrel connectors, about the highest wattage 12V brick I've seen lately with that connector is 180W which is over the limit but available. The 12v bricks over 120W have been going to 4-pin mini-din connectors for current handling over 10A. The connector you typically see with the 19V bricks is the 7.4mm which can handle much more current so you can get bricks up to 330W. So you'll need to change your DC-DC to 19V input style which can run higher power check out the HDPLEX website.

Thanks so much! This is exactly what I was looking for. I was wondering how people used the dell 230w charger with pico PSUs but now I know I need to get a 19v dc to dc.
