Rosewill Tachyon 1000W 80 PLUS Platinum Power Supply Review

Cabling Arrangement




The cable selection is quite nice for a 1000W unit. Unfortunately, the ATX 4+4 and EPS12V connectors are native to the Tachyon. Rosewill gives us six PCI-E connectors over five cables. Peripherals are powered by the ten SATA, six Molex, and one FDD connectors spread over four cables. All the cables are of ample length, but some might find the PCI-E cables shorter than they would like.




All the 12V power from the Tachyon 1000W power supply is provided via a single 12V rail so there isn't much to talk about here.



A Look Inside




Taking the unit apart, we find the classic Super Flower cooling solution. A pair of heat sinks run the length of the unit providing extra heat dissipation where required while still allowing fresh air to penetrate down to the PCB.




A pair of Nippon Chemi-Con capacitors reside on the primary side of the Rosewill Tachyon 1000W power supply.




More Nippon Chemi-Con capacitors are found on the secondary side as well.




Rosewill uses its own 140mm fan to provide the active cooling for the unit. A quick search of the model number will yield that it is manufactured by Globe Fan. What many will find interesting about this particular fan is that it utilizes a sleeve bearing instead of the typical ball bearing that most fans utilize. This will provide slightly quieter operation, but at the cost of longevity.




Something you don't normally find inside the power supply is a spot for an extra fan. Many modders will enjoy this I'm sure.
