The Seasonic Prime TX-1000 shares its design with the entire Prime series, the main differences being the color of the fan shroud and the labels. The TX-1000 has a black and chrome casing with the usual elongated honeycomb pattern applied on the back and front sides of the casing. The power supply has a length of 170mm, a height of 86mm and a width of 150mm.
The Prime TX-1000 has the same fan grill as the rest of the Seasonic Prime series; however, this unit has a chromed fan grill to match the Titanium certification. The Prime logo is applied on a separate surface that is chromed. The grille has a wide honeycomb pattern that acts as the main intake for the 135mm fan installed behind.
The power supply has the same shape on the sides as other Prime units. These cutouts will act as exhaust ports for the airflow generated by the 135mm fan. In addition to the cutouts, the sides of the power supply have the Prime logo applied on the same chromed surface as the front mesh.
The back side of the Prime TX-1000 has the usual honeycomb pattern grille acting as the main exhaust port. On this size, there are only two buttons, the On / OFF switch and the hybrid fan control button.
The modular connectors for the TX-1000 are located on the front part of the casing. The power supply has no less than 16 modular connectors. Two for the motherboard 24Pin cable, Six for the peripheral components and 8 for the CPU and PCIe connections.
As is the case with most if not all Seasonic power supplies, each modular connector is properly labeled. The text being painted on the metal surface of the casing and not on a cheap paper label. In addition, each connector is part of a highlighted group, and this keeps things organized.
The top part of the power supply has the standard specification label. This includes the wattage and rails and the model of the power supply.
The cables of the Prime TX-1000 are flat and have no sleeving on them, the exception being the 24-pin motherboard cable which is thick and has sleeving protecting it. Flat, ribbon style cables are better in the sense that you can stack them and have an easier time routing them around the system.
The fan used with the Prime TX-1000 is made by Hong Hua and has the model number: HA13525M12F-Z. The fan uses a Fluid Dynamic Bearing system and has a maximum rated speed of 1,800 RPM.
As is the case with all fans that are used with Seasonic units that feature their Hybrid fan control. This fan can work in a semi-passive mode based on the wattage load of the power supply.
The internal build quality is great, and what we’ve come to expect from Seasonic and the Prime series. The mosfets are directly cooled by large aluminum heatsinks while the rest of the components are actively cooled by the before mentioned fan.
As always, the filtering starts at the back of the power connector with two X caps and four Y caps on the PCB. A good thing to see is that the smaller PCB at the back of the unit is connected to the main PCB using connectors and not soldering. This lowers the chances of losing power and increases the reliability of the unit.
The APFC section has not one but two Rubycon capacitors, with a maximum operating temperature of 105°C and the specifications: 400V, 470uF. It’s worth noting that this power supply has been sold with different APFC capacitors before, so your unit might use different models of capacitors.
The APFC MOSFETS are made by Infineon and have the model number: IPP60C7099. To properly cool them, one of the main heatsinks of the unit is directly attached to them.
On the Prime platform, the supervisor chip is made by Weltrend, and has the model number: WT7527V. This chip is responsible for the protections of the power supply. It is installed on the secondary vertical PCB on the side of the unit.
The 5VSB Buck converter used on this power supply is made by Leadtrend and with the model number: LD7750R.
The Prime TX-1000 uses capacitors made by Nippon Chemi Con and Nichicon.
