Strangely enough, FSP didn't equip the HPT750M with a semi-passive operation as is normally the case with very efficient PSUs nowadays. However, we don't mind the lack of a semi-passive mode and even prefer the fan to spin at light- and mid-level loads since it cuts down on internal heat build-up. The cooling duties of this PSU are handled by a 135 mm fan, and all protection features are present, including OTP (Over Temperature Protection). The maximum operating temperature for its continuous full power delivery is restricted to 40 °C even though the ATX specification recommends no less than 50°C. We will conduct our most stressful tests at >45 °C ambient in order to check on how well this platform copes with high operating temperatures; we always prefer to take a PSU through its worst-case scenario before providing you with an opinion on it.

This is the first time FSP provides a ten year warranty, which is probably due to other brands having done so for quite some time now (Corsair, EVGA, and Seasonic). This warranty race is in our opinion meaningless, and this is now clearly becoming more evident with the mining craze where PSUs are called upon to operate at very high loads around the clock and under often sub-par ambient temperatures. No PSU can withstand such abuse for ten years, which should have brands be more realistic when it comes to their provided warranty periods if they don't want this whole matter to eventually backfire on them.
The +12V rail can deliver the PSU's full power alone. This is a typical scenario in units that use DC-DC converters for the generation of the minor rails. The 5VSB has the typical capacity of 12.5 W. It would be nice if it were a bit stronger, although we are pretty sure its OCP triggering point is set much higher.

Cables and Connectors, Power Distribution
The HPT750M offers a couple of EPS and six PCIe connectors, along with 14 SATA and five 4-pin Molex connectors. This is a great number of connectors for a 750 W unit, which is clearly indicative of it belonging to the high-end category. FSP even threw a Berg connector into the bundle for those of you who still have some use for it.
|Description||Cable Count||Connector Count (Total)||Gauge|
|ATX connector 20+4 pin (600 mm)||1||1||18-22AWG|
|4+4 pin EPS12V (700 mm)||2||2||18AWG|
|6+2 pin PCIe (500 mm+150 mm)||3||6||18AWG|
|SATA (500 mm+155 mm+155 mm+155 mm)||2||8||18AWG|
|SATA (500 mm+155 mm) / Four-pin Molex (+155 mm+100 mm)||2||4 / 4||18AWG|
|SATA (500 mm+155 mm) / Four-pin Molex (+155 mm) / FDD (+155 mm)||1||2 / 1 / 1||18-22AWG|
Cable lengths are satisfactory, and the same goes for the distance between connectors, which is over 15 cm on all SATA and peripheral cables. It is in our opinion a major design flaw to keep the distance between peripheral connectors short since most components (e.g. fans) with such connectivity are usually installed pretty far apart from one another.
Since this PSU features a single +12V rail, we do not have anything to comment on when it comes to its power distribution.
