The FSP Hydro PTM 750W utilizes an LLC half bridge topology with DC-DC for the minor rails.

FSP HydroPTM 750W

Upon opening the case we find the Protechnic Electric MGA 13512XF-A25 FDB fan with the following specs. It’s rated at 12V, 0.38A, 4.56W, 115.8CFM, and has a max RPM rating of 2300.

Here’s the Hydro PTM with it’s top off. With everything spaced out fairly well, there shouldn’t be any cooling issues.

Here we can take a tour around the unit, once we have the main PCB pulled from the casing.

Our transient filtering starts off at the back of the AC receptacle with two Y caps and an X cap. The filtering continues on the main PCB with two more Y caps and another X cap, two CM chokes, and a MOV.

On the left, we have the bridge rectifier, a GBJ2506. On the right, we have our first daughterboard which houses the PFC controller, an Infineon 2PCS02.

Here we have one of the two primary capacitors removed, a Rubycon 420V330µF MXH series rated at 105°.

Located on the outer part of the heatsink on the primary side is our three Toshiba TK20A60W MOSFETs for the APFC. On the back side of the heatsink, we have a CREE C3D06060 boost diode that’s tucked in behind primary cap we took out.

At the other end of the heatsink, we have the two main switchers, a pair of STMicroelectronics STF26NM60N’s with a Silicon Labs Si8233BD driver located on the rear of the main PCB.

Located on a daughterboard between the APFC parts and the rear of the modular interface PCB we find the LLC resonant controller, a Champion CM6901.

Throughout the Hydro PTM we find several Chemi-Con and Rubycon electrolytic capacitors.

Just in front of the DC-DC PCB daughterboard, we have two small heatsinks that are used to aid in cooling the +12V MOSFETs which are located on the solder side of the main PCB.

Directly in front of the DC-DC PCB, we find several Teapo polymer capacitors. The DC-DC board itself is populated with FP and CapXon polymer capacitors.

Just behind the DC-DC PCB, we have another daughterboard that houses the protections IC, a SiTI PS223.

Our modular interface PCB is populated with a few Chemi-Con electrolytic caps, and several Toshiba polymer caps. Soldering quality doesn’t look to bad.

Looking at the soldering side of the main PCB, we see that FSP has done a pretty good job. However, we do have some infractions when it comes to long component leads.
