Dirty Cheap doubler PSU

Hello everyone! Would like to ask for advise, what's the best AND cheapest PSU exists nowadays? I need something for pure 5V usage, primarly checking fans and filling up my loop (as you know, you power-on pump only in order to fill the loop, etc.)

Or any - even cheapest and LQ china PSU will easily handle maxed D5 pump without sparking?

P.S. BTW, are there general choosing-discussion thread exist at all? Dunno if it is right to create new topic for every question....

What is the voltage and current rating of the fans and pump ? I think an average 12V fan is around 300mA

Any average 12V wall adapter, from say, a modem, or cableTVbox, is usually rated at least 0.5A, I have a box of these for some reason, most households have them from the cable/internet company, and other random electronics.

Do u have any of those ?

As for 5V versions of those, also super common and FREE (everyone has them), just check the current ratings are high enough.
