Performance (40% of the final score) – Our standby tests provided great results with no deductions. During the transient tests, we did have a couple of +12V hiccups in the S&C section costing the Hydro PTM a half-point deduction. In the voltage regulation department, we had some pretty decent results with all close to the 1% +/-, which leaves me pulling another half-point. We had no issues hitting the 80PLUS Platinum figures, so no deductions there. Ripple suppression on the Hydro PTM was very good as well with single digits on the minors and only 22 mV on the major. That leave’s us with an overall performance score of 9.

Functionality (20% of the final score) – With this unit being in the higher end bracket, I expected to see it come with a few goodies whether it be extra Velcro strips, Zip ties, or something. They do give you an option of deciding if you want to keep the blue stickers or replace them with the red or green ones. That’s a nice adder, but not enough to compensate for the lack of extras so we’re pulling a half-point. I am also not fond of the single piece of paper folded up being considered a user manual, which means another half-point deduction. The Hydro PTM is fully modular so no deductions there. I do like the flat cables on occasion, but I’m not a fan of them on the 20+4 ATX cable. I think FSP did well with the connector count for the most part. However, I still like having at least one cable dedicated to 5.25″ connectors just for accessories which means another half-point deduction. Although I’m not dinging FSP for it, the misleading “0dB Zero Noise” label on the box does need to be removed. This leaves us with a functionality total of 8.5.

Value (20% of the final score) – With this review coming in a bit late (all my fault), I feel I’ve still got to give it its score based on the current pricing just to keep things fair. Right now theĀ  FSP Hydro PTM 750W is listed for $134.99 US @ NewEgg. We also see the Seasonic FOCUS Plus 750W Platinum @ $119.57, while units like the Corsair HX750i & the Seasonic PRIME Ultra 750W Plat coming around $145.00. We also see a few topping the $160 ish mark like the Rosewill TACHYON 750. This moves the FSP towards the lower end of the scale, which puts us at an 8.5 here.

Build Quality (20% of the final score) – When it comes to build quality, FSP has always done pretty good with today being no exception. The only thing I’m going to ding them on today is the long component leads I found on the solder side of the main PCB. So that puts us at 9.5.

Overall, the Hydro PTM 750W gave us everything that FSP said it would. We have a fully modular, platinum certified, single +12V rail, quality components, which makes this a competitive power supply. It’s hanging in there with the best of them. With some tweaks here and there it could easily improve its position in the market.
