FSP Hydro PTM 750W Power Supply

I want to thank everyone for being patient with us while we get things lined out. We’ve made a lot of changes and still have some to come. Right now, it’s time to start working on that review pile that’s been growing for the last 4 or 5 months. We’ve looked at a few of the Hydro series units in the past (a couple of the G’s and an X), today we’re going to take a look at the Hydro PTM 750 from FSP.

Yes, Yes, I know! This probably isn’t what you expected to see for my first review back. I’ve had several units show up over the past 4 or 5 months not to mention the pile I already had. Well the Hydro PTM just happen to be on the tester when all this started.

The Hydro PTM series is a fully modular design that comes in three different configurations, 550W, 650W, and 750W. As we can see by the icons displayed across the front of the box. The Hydro PTM is not only ready for Intel’s latest and greatest CPU but their also VR ready! FSP must be really proud of the Hydro PTM seeing that they’ve also given it a 10-year warranty, included 100% Japan-made E-cap’s, offers OdB Zero Noise, and is rated for 80PLUS Platinum. With all that being said, we must be looking at a top contender for the 750W range.

Turning the box around we are greeted with more in-depth information. Here are the main features listed for the Hydro PTM.

  • Unique product ID with changeable side stickers for DIY enthusiasts and gamers.
  • Complies with newest ATX12 v2.4 & EPS12 v2.92 standards.
  • High Efficiency ≥ 92%.
  • Active PFC ≥ 99%.
  • 80PLUS Platinum Certification.
  • Powerful +12V single rail design.
  • Advanced full modular design with ribbon cables.
  • Full Japan-made electrolytic capacitors.
  • Support 6+2 pin PCI-Express Connectors.
  • Quiet and Long-Lasting 135mm FDB fan.
  • Complete Protections: OCP, OVP, SCP, OPP, UVP, OTP.
  • Global Safety Approved.

FSP has added in a few extras such as the special heatsink designed for the 12v switching circuit. They’ve also implemented a server grade bus bar design for connecting the daughter board to the main board to minimize any power loss pushing for even more efficiency. Pair all that with a nice DC-DC design and some tight voltage regulation, the Hydro PTM, by all means, should produce some nice testing results. We’ll just have to see if it sinks or swims.

Along the side, we have their power specs listed.

As stated earlier, we have a single +12V rail rated for 62.5A, with the two minor rails rated for 20A each.

The Hydro PTM utilizes an intelligent fan speed control circuit designed with a 135mm FDB (Fluid Dynamic Bearing) to provide low noise and reliable operation at low to medium loads. As we can see by the above graph, we should run 700+/- RPM up until 60% (roughly 450W) and then ramp up to a little over 1200+/- RPM at full load.

With the Hydro PTM being rated for 80PLUS Platinum, we expect to see efficiency numbers to be at least 90% @ 20% load, 92% @ 50% load, and 89% @ 100% load. Of course, we won’t complain if they’re better than that, will we?

FSP even gives you a basic cable and connector layout. All the information one would need to have if shopping for a unit in a retail store.

Opening up the box, we are greeted with a nicely packed PSU. Included in the smaller box are the modular ribbon cables and the power cord. Next, we have a sleeve containing the two extra stickers options should you want to change the color from blue to red or green. Lastly, we have a pamphlet and a single piece of paper folded up several times acting as a user manual.
