With the exception of its load-regulation performance, the Hydro PTM 750 W PSU ticks all the right boxes for me. It is resilient to high temperatures and highly efficient, its 5VSB circuit is one of the most efficient I have encountered so far, ripple suppression is excellent, its hold-up time is long, and the power ok signal is accurate; also, all protections are present and function as they should. The PSU's fan isn't even that noisy at full speed and is controlled by a very relaxed fan profile. I am sure some would prefer the option of a semi-passive mode, but I personally prefer the fan to constantly operate since such an approach puts less stress on components sensitive to high temperatures, like electrolytic caps.
The upgraded version of the Hydro G platform the HPT750M uses is not only a good performer, but also looks to be very reliable or FSP wouldn't be supporting it with a ten year warranty. In addition, this PSU comes with a truckload of connectors, including a couple of EPS, six PCIe, and fourteen SATA connectors! Finally, the cherry on top with this product is its unique look.
The only downsides I was able to spot are its EMI noise levels at low frequencies and loose load regulation, especially on the minor rails. The product's price is also a bit high, putting it in a very tough category. Given the very good PSU offerings in today's market costing less than 100 bucks, FSP should seriously examine the possibility of offering the HPT750M at a lower price closer to 110 bucks or even less if it wants to attract more buyers with the HPT750M.
Another upgrade FSP could implement in the next revision of this line would be the addition of an optional semi-passive operation. Given this PSU's fan has a rather high minimum RPM, a semi-passive option might be preferable to some users. Another option would of course be to use a fan with a lower minimum RPM.
