The XPredator 750GM is a semimodular PSU featuring a DC-to-DC topology for optimal voltage regulation and high-efficiency performance. 80 PLUS testing shows that this PSU is indeed efficient, as it meets the 80 PLUS Gold certification with an efficiency of 91.24% at 50% load and 90.71% at 20% load. Aerocool provides the XPredator 750GM with a single 62A +12V rail to ensure that hungry graphics cards get the power they need. This PSU includes four 6+2-pin PCIe connectors to support powerful SLI and CrossFire GPU configurations.
In addition to the 62A +12V rail, the XPredator 750GM has a +3.3V rail rated for up to 20A and a +5V rail rated for 20A. The power distribution is fairly typical for a 750 watt power supply. This PSU also keeps a watchful eye on those rails when powering your PC’s hardware. There are protections for overvoltage, undervoltage, overpower, short-circuit, and surge and inrush conditions. And by monitoring both the incoming and outgoing power, Aerocool helps to improve reliability and extend the lifetime of the PSU.
As befits a (X)predator, this PSU is built for stealth. Aerocool installs a loadcontrolled PWM fan to keep noise to a minimum under most circumstances. For instance, Aerocool indicates that the fan will operate at less than 1,000rpm when the PSU’s output is under 70% load. And under full load, the fan will increase to more than 1,500rpm to cool the XPredator 750GM’s internals. We also like that the XPredator 750GM is only 6.25-inches long (including cable bend), so it can fit into many small form factor cases.
There are no surprises with connectivity, as the XPredator 750GM includes the types and number of connections we’d expect from a 750 watt power supply. Only the 20+4-pin main power and 4+4-pin connectors are hardwired to the unit. Both of these cables are 23.6-inches long, which provides enough slack, in most cases, to let you route the cables behind the motherboard tray for the cleanest possible look. For your system internals, there are eight SATA connectors, four Molex connectors, and one FDD connector. All of these connectors, as well as the PCIe connectors, are available via modular, flat black ribbon cables.
We installed the XPredator 750GM into a system with Intel’s Core i7-6700K, GIGABYTE’s Z170X-GA-SOC FORCE, and two MSI GeForce GTX 980Ti Gaming 6G cards in SLI. We simultaneously ran Prime95’s Small FFT test and Unigine Heaven’s 4.0 benchmark at the highest settings to put a heavy load on the PSU. The XPredator 750GM produced a maximum wattage of 671 watts at the impressive power factor of .990. During the testing, power factor was consistently between the excellent power factor ranges of .980 and .995. We also tested the XPredator 750GM with one MSI GeForce GTX 980Ti Gaming 6G. Maximum wattage dropped to 444 watts at a power factor of .978. Under the lighter load, power factors were typically between .970 and .982.
The Aerocool PSUs we reviewed in the past were primarily entry-level models. The XPredator 750GM includes the type of internal switching hardware and protection features that enthusiasts look for in the 700 watt range. The unit’s small size and modular cabling features also make this PSU a good choice for builders who require a power supply that takes up minimal space inside a case. Aerocool tells us that the XPredator 750GM, as well as the XPredator 1000GM, will be available around the end of April or early May.
