What you save with picoPSU is the space. You won't save any money when going with one though. Then again, reason why to go with picoPSU in the first place is to save space, or is it not?

To get a bit cheaper, you can go with: PICOPSU-150-XT,

and 150w AC-DC Power Adapter, 12v 12.5A ,

Note: it's output is 150W, 10W less than the one above.

But if the space isn't that important and saving money is the main reason then, Corsair SF450 SFX PSU,

or Seasonic S12II-430 ATX PSU,

Thank you so much for the help. Although, I was hoping for something that would be easier to get in canada or at least a little cheaper. Thats almost 100 USD together and Id still have to pay shipping. If there are no other solutions, I could go with these, but id prefer something a little cheaper if possible.

Thanks

Thanks for your help, i think im going to go with the pico 150w. I just hope that the power efficiency is high enough so that it doesnt drop below 135w

You're welcome.

As far as power efficiency goes, it doesn't affect what PSU outputs. Instead, it affects what PSU draws from the wall.

Few examples:
Let's say 80+ Bronze certified 650W PSU has a load of 500W on it. PSU still delivers 500W worth of power to the PC components but since it's efficiency is 85%, PSU itself draws from the mains 575W. The extra 75W PSU draws from the mains is dissipated as excess heat.

But if we were to take 80+ Titanium certified 650W PSU with the same load of 500W on it, PSU still delivers 500W to PC. But since 80+ Titanium PSU has efficiency of 94%, it will draw 520W from the mains. Leaving only 20W worth of power dissipated as excess heat. Compared to the 80+ Bronze unit, 80+ Titanium unit is much more efficient.

Depending on what efficiency level that picoPSU power brick has, at full load (150W), it can draw from the wall between 159W (80+ Titanium efficiency) and 195W (70% efficiency).
