Performance (40% of the final score) – there’s nothing as easy to score as a Seasonic. First, the voltage regulation. Which… only averaged out at 0.16% in the hot box, which is way inside the mythic level. No deduction there. Sadly, the full S&C point has to go away due to the power on spike behavior. But the rest of the unit was again flawless. No deductions for efficiency or ripple control… it was all good, there. 9.

Functionality (20% of the final score) – I’m going to make two small deductions here. First, half a point comes off for the CPU cable length. I want more cable for this size of a unit. Second, documentation kills another half point. I want info in my manuals, not marketing. But there we stop. I really appreciated the additional modular cable connectors and individual PCI-e cables… those will help a lot with high power draw video cards. 9.

Value (20% of the final score) – $259.90 at NewEgg gets you one of these. That’s expensive, but so are the other Titaniums it competes with. And it’s the cheapest of those. Next cheapest is Thermaltake, asking for $17 more. But that one has those RGB lights if that’s important to you. Silverstone’s model runs $40 more money but includes another hundred watts of go. And I’m not sure what happened to EVGA, but their T2 is now at the top of the heap, fifty bucks more than this one. No, the only real competition is the outgoing original PRIME unit, priced the same as this one. 10.

Build Quality (20% of the final score) – Seasonic did good here, of course. 10.

The story here is much the same as the 650W model. Performance wise, there’s no reason to get this unit over the old model. However, there are enough functionality reasons this time out to steer you toward the new model. I still want to see a lot improved around that power on spike performance, but for now, Seasonic makes this unit an easy choice if you really want to go Titanium at this power level.


  • amazing voltage regulation
  • excellent build quality
  • better than excellent ripple control
  • lots of accessories
  • 12-year warranty

The BAD:

  • nothing major
