CONCLUSION

   The PRIME TX series of power supply units by Seasonic may not be fully compatible with the new ATX v3.0 standard (at least not yet, next generation will be) but rail stability is nothing short of impressive. Noise levels are equally good, yes, my test rig was unable to surpass even 1100W of power draw so I do expect the profile of the fan to add a couple more dBA at 1300W but again, that’s a very good result (always compared to similar wattage models). And then we have build quality which is pretty much excellent across the board thus justifying the 12-year limited warranty Seasonic offers. The two 12VHPWR connectors also render the PRIME TX-1300 one of your best choices out there if you plan on getting one of the new GeForce RTX cards (as does the 80 PLUS Titanium efficiency certification). Size should be your sole concern with this unit, granted it’s highly unlikely that anyone would be pairing this unit with a small PC case (especially if one of the new GeForce RTX cards is also on the menu) but anything’s possible.

   Seasonic currently has their PRIME TX-1300 for USD567 inside the USA (Amazon.com) and for 469.25Euros inside the EU (Amazon.de) so it certainly doesn’t come cheap. Still from what i see other PSU models with two or more 12VHPWR modular cables cost roughly as much but they are not made by Seasonic and they are not covered by a 12-year limited warranty. Yes, the fact that the PRIME TX line is not ATX v3.0 certified may let down some potential buyers but getting this rail stability (not to mention build quality) is not something you can expect, even from most units that currently follow that standard. Performance, build quality, output, noise levels, 12VHPWER connectors, the PRIME TX-1300 by Seasonic has it all and that’s why it gets the Platinum Award.
