Specifications

Efficiency meets only the basic 80 Plus certification. according to Thermaltake at least since at the time of review this unit still wasn't officially certified by 80 Plus organization. Regarding its protections: only UVP (Under Voltage Protection) and OTP (Over Temperature Protection) are missing. Since the max operating temperature of this PSU is restricted to 40°C (while ATX spec recommends 50°C) we would like very much to see OTP present, to protect the unit from burning up in case the internal temperature goes too high. The small cooling fan is equipped with sleeved bearings and its maximum speed reaches 1700RPM, to cope with the unit's thermal dissipation. The dimensions are pretty compact with only 140mm depth and the weight is low too. Finally the warranty is at three years, a satisfactory period for the category that this PSU belongs too and the price is a bit higher than what we expected. Let's see if the performance of the SP-730P will justify this price.


The SP-730P has a single +12V rail which can deliver up to 56A, so it's strong enough to feed two mid-level VGAs along with a strong CPU. The minor rails are quite powerful at 150W combined while the 5VSB rail is sufficiently strong with 3A max.

Cables & Connectors, Power Distribution

Unfortunately only the 24 pin ATX cable is sleeved so most users will be highly disappointed by the view of the naked wires and on top of that cable management will be much harder. To speak frankly from a PSU that costs 100 bucks we expected all its cables sleeved and not only one of them. The number of available connectors is sufficient for the category of the PSU, however a second EPS connector along with two two additional 4 pin Molex connectors would highly increase its usability. The length of the 24 pin ATX and the EPS cables is adequate for this PSU, which most likely will be installed in mid-tower cases and not in full towers. As for the PCIe cables these are short and 100mm additional length up to the first connector would be a better option. Thankfully the distance among all connectors is the right one, at 150mm. Finally all connectors use 18AWG wires, which is the recommended by ATX spec gauge size.

Since this PSU features a single +12V rail we do not have anything to comment about its power distribution.
