Are those Pico PSUs worth it? (feddit.de)

I have an HP g3 mini and a Dell Optiplex flying around, both similarly specced. The HP has an i5 6500t and 16gb DDR4 RAM, the Dell has 8gb DDR3l, so nothing too different.

However, the Dell draws around 15W while idle, the HP one 5W.

The only difference I could think of (and that is in my power to change) is the PSU. The Dell has one of those SFF PSU for up to 180W while the HP has an external 65W power brick with a barrel jack.

So my question is: Does anyone have experience with one of those Pico PSUs? I guess they should be more efficient? I'm not planning to put anything power hungry into the optiplex.

They both have (almost) the same CPU, just once in the T variant.

The T variant is the low-power, lower clocked (3.2ghz vs 2.5ghz) almost half the TDP (65w vs 35w) variant; kinda the whole point is it's going to use less power.

Yes, but ⅓ of the power? That's seems like a lot.

The T variant is for thermally constrained systems. May not use less power, for example if a non-T completes a task faster and goes to idle
