Efficiency is compliant with the 80 PLUS Bronze requirements and the max operating temperature according to Thermaltake is only 40°C. During our tests we will give it a shot and go above this limit; hopefully the unit won't break since it lacks Over Temperature Protection (or OTP). The 140mm fan can operate at very high RPMs and we usually meet such strong fans in CPU coolers and not in PSUs, so we expect it to output significant noise despite Thermaltake's claims for only 16dBA noise.
The unit's footprint is normal for its capacity and finally the provided warranty is short compared to the five years that Corsair gives along with the TX750M, which costs a few bucks more than the SP-750M.

This is a single +12V rail PSU which alone can deliver almost the unit's full power, a typical case for a PSU that utilizes DC-DC converters for the minor rails generation. The latter have a combined power of 130W so they are rather strong for today's standards and the PSU's category. Finally the 5VSB can deliver a little more power than the standard, for contemporary PSUs, 2.5A.

Cables & Connectors, Power Distribution

With the only flaw being the single EPS connector the unit is equipped with a sufficient number of connectors. The native cables are only two and include the basic ATX and EPS cables. Their lengths are satisfactory and will be enough to cover even big chassis, although in very large cases additional 100mm in the EPS cable would make things easier. All PCIe cables are modular and the distance up to the first connector is kind of short. We would like to see additional 100mm here, too. Thankfully the distance among all connectors is sufficient. Finally all connectors use 18AWG wires, which is the right gauge size according to ATX spec. As we wrote many times in the past thicker 16AWG wires cause lower voltage drops but make the cables more rigid so cable management tasks get harder.

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