I am in need of a new Power Supply and thought I would ask, is there one particular one or brand everyone agrees on or is happiest with? My friend has the ProTek 40 amp model and is happy with it.........

I should add I will be using it with a ProTek 620 Duo charger.

Any suggestions would be greatly appreciated.

Depends on what your charging and how many amps.

I am charging RevTech Double Deuce 100c shorties at 4amps

Any 20A unit should be fine. There are also a number of people selling converted server power supplies for around 50-60 bux. These are about 47A units.

Definitely converted server power supplies!!

agreed, 100A for only less than $30

Max amps 47 amp 80.00 great power supply

Yup my max amps 47amp 575watt supply is on the ups truck almost here for my hitec x2 400 charger great price, if you're looking for some other good power supplies check out progressive rc

go to ebay.. with $15 you can get a 900 watt server PS.. a switch and extra rx lead and some 12ga noodle wire and 4 mm female bullets you have a 70 amp ps that will last a lifetime..I have done 50 as of now and a few guys push these to the max..all is good..Just make sure b4 u buy you can find the info to jump the correct pins to get it to run..
thats a total of $25 max for 70 amps at 13.8v..

The Max Amps ps is just a server supply, just ocerprices like the rest of their stuff.

This is a TRUE FACT

I bought two of these
Been running over a year with some serious use
Heli, jets and cars over fifty lipo's in my collection
Also my charge station is two ICharger 208B's at 24V

Fast shipping great communication

80$ isn't a issue for me after I've already put down over 1200$ for my new setup and it has enough amps and wattage to supply for what I'm charging, IMO I'd buy a new supply rather than a used pc supply, I do agree max amps is overpriced but the supply I don't have a problem w/

The one thing I like about Power Supplies marketed towards "RC" is they are finished nice. A raw aluminum box with wires hanging off of it just seems sketchy to me.

They don't have to stay raw aluminum...
