FSP Hydro PTM 650W PSU Review: Clean, Quiet Power for Mid-Range PCs

EMC Pre-Compliance Testing

To learn more about our EMI testing equipment, please check out How We Test Power Supply Units.

EMI Results - Average Detector

Some of the recorded spikes exceed this test's limits. As a result, the HPT650M fails. Fortunately, at higher frequencies, conducted EMI emissions are low.

EMI Results - Peak Detector

A couple of spikes at higher frequencies stand out in our chart. They remain under this test's maximum tolerance, though.

    Is there a reason why they put the word "Hydro" in the title?

    there used to be some really crappy power supplies in the world but now most of them are fine. you had to be really careful or you burn up everything. that doesn't happen anymore.

    there really only three companies that make PSU now and they all just badged for different brands. one might insist on using higher grade but its still a superflower.

    rosewill capstones are usually superflower and 1/2 the money

    Even so, for guys like me who only use a "normal pc" without OC, this one will do just fine right? Cause i got it from black friday for the right price, while Seasonic stuff are insanely expensive in my country

    Some of the Rosewill Capstones , don't get good reviews from buyers , I avoid them.

    POLICE_LEDUC113 - Yes, This is a better than average power supply. Not the absolute best but priced in the US with the absolute best. If you got it at good price compared to the competition then it will do well for you.
