As has already been mentioned in the prologue, efficiency is 80 PLUS Titanium, and the unit features a fully modular cabling design. SAMA also says it to be capable of delivering its full power continuously at up to 50°C; however, we encountered shutdowns due to OTP (Over Temperature Protection) at operating temperatures above 46 °C with a full load in our tests.

Every protection-specific feature but OCP (Over Current Protection) has been included, but OCP also isn't required in single +12V rail PSUs. Cooling duties are handled by a quality Sanyo Denki fan with a lifetime of up to 40,000 hours at 60 °C. There is no semi-passive mode, but this fan is very quiet at low speeds, so the lack of a fanless option at light loads won't be a significant problem to most. However, its fan profile is pretty aggressive at operating temperatures above 30 °C. At almost 19 cm long, this PSU is also quite large, while it's priced at around $200 in China. Given its high quality modular cables, its price doesn't look too stiff.
The single +12V rail can deliver up to 780 W on its own, so it's strong enough to support a powerful gaming system with two high-end VGAs. The minor rails look weak, but you won't need more than 100 W of combined power from these rails since most PC components nowadays are fed by the +12V rail. The 5VSB rail is a little stronger than is the norm for today's PSUs.

Cables & Connectors, Power Distribution
There aren't enough EPS and PCIe connectors for a high-end 800 W unit. There should at least be two EPS connectors, and SAMA could easily provide an additional two PCIe connectors. There are, on the other hand, plenty of SATA connectors, and enough 4-pin Molex connectors. The cables are long enough, and the distance between connectors is ideal. Every connector also uses 18-gauge wires, which is as the ATX specification recommends.
|Description||Cable Count||Connector Count (Total)|
|ATX connector 20+4 pin (570mm)||1||1|
|4+4 pin EPS12V (620mm)||1||1|
|6+2 pin PCIe (500mm)||1||1 / 1|
|4 pin Molex (500mm+150mm+150mm+150mm) / FDD (+150mm)||1||4 / 1|
Since this PSU features a single +12V rail, we do not have anything to comment on when it comes to its power distribution.
