Seasonic PRIME TX-750 Titanium


The following system was used to test the cooler:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– RAM: Ballistix Tactical Tracer 16GB DDR4 @ 2666MHz
– GPU: MSI GeForce RTX 2070 Super Gaming X Trio
– SSD: Crucial MX 500GB
– HDD: WD 1 TB Blue
– CPU Cooler: CoolerMaster MasterLiquid 240 with NoiseBlocker eLoop B12-PS
– Display: AOC i2769VM
– Case: Phanteks Enthoo Luxe White
– OS: Windows 10 64-bit


The above system has a power consumption of approximately 502W when in full load and 68W when idle, in order to test the efficiency of the Power Supply, the power draw of the system was measured at the wall socket. Also, the voltages were measured on the +12v +5v and +3.3v using a multi-meter.

To load the system to its maximum the stability test of the AIDA64 Extreme 6.25.5400 was used with Intel Burn Test V2.
The Power Supply was tested with the system both idle and at maximum load.


Power Supply efficiency


For rail voltage tolerance levels, ATX (Power Supply Design Guide) specify that a 5% variable fluctuation is acceptable.


Voltage oscillation idle


Voltage oscillation load


The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.


Final thoughts

The Seasonic PRIME TX-750 Titanium is available for approximately 260 USD or EUR, and while it is not a small price, it is one of the cheapest Titanium rated units available.
The performance is very good and makes the PRIME TX-750 Titanium one of the best power supplies I’ve ever reviewed so far. With a load of approximately 500W, the power supply maintained a stead efficiency of 94.2%.

The improved Seasonic Titanium platform uses a wireless internal design, which not only increases the reliability but also reduces the airflow restrictions inside the casing.
In terms of sound, the 135mm fan used with the PRIME TX-750 Titanium is silent, with a maximum noise output registered of 17 db(A). In addition, the fan can be turned off completely if the power supply does not exceed a certain temperature threshold.

In conclusion, the Seasonic PRIME TX-750 Titanium is a great power supply which not only offers a very good performance but also has a 12-year warranty. The only inconvenient with this power supply is the price, however, at this level of quality and performance, it is a worthwhile investment.
