1600 WATTS
01 / POWERSixteen hundred watts.Certified.
The PRIME TX-1600 delivers 1600 W continuous with 80 PLUS Titanium certification, the highest level: 94 % efficiency at 50 % load. What does not turn into heat stays in your build and in your bill.

Load regulation under 0.5 %
Voltage stays almost flat when the load changes suddenly. That is the figure Seasonic publishes for this series.
Japanese capacitors
105 °C Japanese electrolytic capacitors and a 100,000-hour MTBF at 25 °C. That is why the warranty runs for twelve years.
NOCTUA
02 / SILENCEThe edition you do not hear.Literally.
This version swaps the 135 mm fan of the regular model for the 120 mm Noctua NF-A12x25, with a redesigned grill. Seasonic measures 8 to 10 dB(A) less across the whole speed range.

Noctua colours, on the individually sleeved cables too. You either love it or you hide it: that part is up to you.
ATX 3.1 AND PCIe 5.1
03 / STANDARDSThe new connector.Twice.
It meets ATX 3.1 and PCIe 5.1, the standards current graphics cards ask for. It ships two native 700 mm 12V-2x6 cables, with no adapters in between.
Two 12V-2x6 cables
Two 700 mm 12+4 pin cables come straight out of the unit. Enough for a high-end card and headroom for the next one.
Power spikes
ATX 3.1 defines how a unit must handle the brief spikes of modern cards. This one meets the standard; the manufacturer does not publish a peak figure, so we do not invent one.
Six 8-pin PCIe
Besides the 12V-2x6 there are six 750 mm PCIe 8/6 pin cables for cards and accessories of the previous format.
WHAT IT IS FOR
04 / USE CASESExtreme gaming.And real work.
A 1600 W unit is not a whim: it is what you buy when the build asks for current all at once and cannot shut down in the middle of a job.
Extreme gaming PC
High-end graphics card, unlocked processor, liquid cooling and ten fans: the unit works far from its limit, where it is more efficient and quieter.
Workstation
Rendering, compiling, multi-layer editing and drives spinning at the same time. Twelve years of warranty for a machine that never turns off.
AI workloads
Training or serving models locally keeps the card at full load for hours: sustained load, exactly what the Titanium certification measures.
How much power you need depends on your parts. The "Build your PC" tool adds up the draw of the components you pick.
CABLES
05 / CABLESOnly the ones you use.With the length written down.
Fully modular: every cable goes in only if it is needed. These are the lengths Seasonic publishes, so you know whether they reach inside your case.

It does not fit 200 mm cases
The CORSAIR AIR 5400 in this catalogue takes units up to 200 mm: this one is 210 mm and does not fit. We tell you before you buy them together.
Count the cable room
On top of the 210 mm you have to add the cable bundle that leaves the back. Leave a few more centimetres of slack.
110 V mains in Colombia
Seasonic states 1600 W between 115 and 240 V, and 1300 W on the 100 to 240 V range. That comes from the official sheet, not from an estimate of ours.

FREQUENTLY ASKED QUESTIONS
What people ask us the most.
If you still have a doubt, write to us before buying.
Isn't 1600 W too much?
It depends on the build. A power supply only delivers what the system asks for: 1600 W leaves headroom for a high-end graphics card with power spikes and for several drives and fans, and keeps the unit far from its limit, where it is more efficient and quieter.
Does it include the 12V-2x6 cable for new cards?
Yes, two native 700 mm 12V-2x6 (12+4 pin) cables. It meets ATX 3.1 and PCIe 5.1.
Why the Noctua edition?
It swaps the 135 mm fan of the regular model for Noctua NF-A12x25 120 mm fan and a redesigned grill. According to Seasonic it runs 8 to 10 dB(A) quieter across the whole speed range.
Is the fan always on?
No. The digital hybrid control keeps it off at low load (fanless mode) and starts it when needed.
Will it fit my case?
It is 210 mm long (150 x 86 mm section). Check that your case accepts an ATX unit of that length; the automatic check is below.
What warranty does it have?
Twelve years from the manufacturer, the ones Seasonic publishes for the PRIME series.
