Testing
The following system was used to test the cooler:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– RAM: Neo Forza Faye DDR4 64GB 4000MHz
– GPU: MSI GeForce RTX 3090 Ti Suprim X
– SSD: Crucial P5 1TB
– Mass storage: NeoForza NFP075 2TB
– CPU Cooler: Cooler Master Master Liquid 240 with NoiseBlocker eLoop B12-PS
– Display: AOC i2769VM
– Case: be quiet! Silent Base 802 White
– OS: Windows 10 64-Bit (After April Update)
The above system has a power consumption of approximately 720W when in full load and 50W 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 digital multi-meter.
To load the system to its maximum the stability test of the AIDA64 Extreme 6.85.6300 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-1000 is not a cheap power supply, however, when looking at other 1000W Titanium rated models, the 300USD price tag starts to look better. The performance offered by this power supply is outstanding, thanks to the high-quality components and build quality. Another thing to keep in mind with this unit is the warranty, no less than 12 years offered by Seasonic.
The performance in terms of the efficiency is great, as we were expecting given that this is a Titanium rated unit. The same can be said for the voltage ripple and the general stability on the 3v, 5v and 12v rails.
In terms of noise output, this power supply is quiet thanks mainly to two things. The used 135 mm Fluid Dynamic Bearing fan and the custom fan profile that is on the conservative side. This means that the fan will remain at a relatively low RPM until the power supply is pushed towards its maximum wattage.
The cables included with this power supply are good, most of them have the flat ribbon style design. This flat design is great as the cables can be stacked and thus, the cable management is made easy. The only cable that is not flat is the 24Pin motherboard cable. Instead of flat, this cable is normal and has a synthetic sleeving protecting the wires.
In terms of pricing, this power supply is not cheap, at around 300-350USD at the time of this review. However, we are talking about a 1000W Titanium rated power supply that has a warranty of no less than 12 years. These features will not come cheap no matter what power supply you choose or who made it.
In conclusion, the Seasonic Prime TX-1000 is an exceptional power supply not only thanks to its performance, but to its low noise output and long warranty period. The build quality is great both internally and the outer casing. The only drawback of this power supply is the high price, but it is justified given the performance offered.
