Hello,

I am building a new HTPC. Since the case I'm using is small (original xbox case), I've decided to use a PicoPSU.
(i have another thread dedicated to the build )

picoPSU 150 XT
http://www.mini-box.com/picoPSU-150-XT?sc=8&category=98...

My question is, thought the PSU itself is rated for 150 Watts, the only AC-DC adapters i can find are 102W maximum.

Has anyone used a PicoPSU and knows if this could be a problem? I'm concerned that the AC-DC wont be able to draw enough current to power my system.

PSU will be powering:

ZOTAC GF9300-D-E LGA 775 NVIDIA GeForce 9300 HDMI Mini ITX Intel Motherboard


Intel Pentium E6300 Wolfdale 2.8GHz 2MB L2 Cache LGA 775 65W Dual-Core Processor


WD caviar 250GB AAKS SATA
LiteON DVD RW SATA


I've hooked up the motherboard with another PSU (no HDD or optical) and measured about 70W with a killawatt meter (accuracy questionable).

Anyone with experience with these picoPSUs, advice welcome.

The 150W picoPSU says up to 96% efficient. You shouldn't have any problems with a 102W AC-DC adapter.
70W is @wall. You have to take AC-DC adapter's efficiency into account as well which will be a bit lower.

Yeah i realized that after i had first posted. 70W at the wall probably translates to ~50W drawn by the system since the PSU i was using is old and not very efficient.

It must work fine since its what people use. The company sells them together. We'll find out i guess i ordered the kit already. Thanks for the input though.

I have a Pico-PSU 120 in my ITX NAS, running with the 102W adapter (the strongest one Minibox pairs with this) - haven't had any problems.
