Efficiency is Gold. As we are used to see in Enhance units, all protection features are present—including Over Temperature Protection (aka OTP). It is one of the most essential protection features, yet many manufacturers choose to not incorporate into their implementations. Unfortunately, Enhance insists on keeping the low 40°C maximum operating temperature threshold for the delivery of maximum continues power, while the ATX spec recommends 50°C. We are, nevertheless, going to conduct our tests at 40-45°C and expect the worst case to cause the shutdown of the PSU after OTP triggers.
The fan that cools down the unit only has a 120 mm diameter because a larger unit wouldn't fit. It doesn't use ball bearings, but is, at least, made by a reliable manufacturer: ADDA Corporation. Moving on to the strongest point of this unit: Its ultra-small form factor due to a length of only 14 cm makes the PSU's installation process into a case, any case, a piece of cake. You, most important of all, won't have to worry about compatibility issues with an ATX-compatible chassis since the standard length for ATX PSUs is also 14 cm. Finally, the warranty of this PSU is set at three years and the price is quite stiff, which will make things tough for the ST65F-G because there are many worthy competitors in its price range.

|Total Max. Power||650W (700W Peak)|
There is a single +12V rail that can output up to 54 A of current, which means that two middle/high-end VGAs and all accompanying components can be supported by this PSU. The minor rails are pretty strong too, although their individual maximum current outputs aren't so high (they are, usually, 25 A each with such combined maximum power output). Finally, the 5VSB rail has enough power to feed a contemporary middle-end system. Another 0.5 A would be ideal, though.
Cables & Connectors, Power Distribution
|ATX connector (550mm)||20+4 pin|
|4+4 pin EPS12V (550mm)||1|
|6+2 pin PCIe (550mm) / 6+2 pin PCIe (+150mm)||2 / 2|
|4 pin Molex (500mm+150mm+150mm) / FDD (+150mm)||6 / 2|
The number of available connectors is good; however, a second EPS connector would be very welcome. Also, two cables hold two 6+2 pin PCIe- and two 6 pin PCIe connectors. The PSU could, in our opinion, easily handle four 8 pin PCIe connectors in total.
The length of ATX-, EPS-, and PCIe connectors should, ideally, be 50-100 mm longer, but such a small PSU is unlikely to be installed into a full tower chassis, and long cables are harder to manage in a smaller case. Thankfully, the distance among all connectors that hold more than one connector is adequate. The 24 pin ATX-, 6+2 pin PCIe-, and EPS connector use 16AWG wires for lower voltage drops, while all the other connectors utilize the standard 18AWG gauges.
Since this PSU features a single +12V rail, we do not have anything to comment on about its power distribution.
