Re: what fuckery is this!?

if you're using 2.5" drives, those only use 5V

Re: what fuckery is this!?

I have the feeling hard drives consume something on +5 V. The question is what the efficiency will be and how the ripple will look.

i know hard drives use about 150mA on 5v and the rest is 12v, so the ripple might be high on the 5v rail and for the efficiency, well, its probably more efficient than my zenith 12 valve valve radio set

If you want to carry that thing with you…

its about the size of both bricks, and how many more drives can it run

do you think i might need a 5v minimum load resistor?

Re: what fuckery is this!?

so can i use the powerman PSU instead of this fuckery? and the bricks turn into a cookery when running!

Yes, as long as the pin-out is correct, you'll have to jumper the ATX connector on or wire in a switch. Granted using a 300w ATX PSU to run a drive or two that might draw 5W ea. is a little overkill, but if you don't have any other use for it, it might not be a bad option.

Well, if it was fan-cooled, at least the airflow would be nice. It's not really crowded inside

Re: what fuckery is this!?

I think the output filtering is a bigger problem.

Look at how the output devices are mounted to the heatsink.

Re: what fuckery is this!?

A power supply should only care about noise passed to its secondary circuit.
Noise it generates itself that passes upstream...well it's not its problem. Some of these devices' parts are small enough that it won't generate that much noise to pass upstream (low impedance loads and long extension wires connected on the same circuit tend to low pass filter the noise anyway), so they omit these parts...

As the chicken hatchling goes... Cheep cheep cheep...

I still think the half bridge cell phone chargers are the more worrisome PSUs... Have enough of them, and it would cause some power factor annoyance...

look at these bricks, how have they not killed the HDD they power yet? can i replace them with this powerman PSU because its only 300w rated and it actually has input filtering?
