Pros
- Includes a native 12V-2x6 connector for next-generation GPUs like the RTX 5090 and RX 9000 series.
- Achieves 91% to over 95% efficiency at 50% load, exceeding 80 PLUS Gold certification.
- Features 100% Japanese 105°C-rated electrolytic capacitors for component longevity.
- Maintains precise voltage regulation, with the 12V rail holding at 0.4% deviation.
- Operates passively at low loads due to its hybrid fan control with a 135mm FDB fan.
- Comes with a 10-year warranty, indicating manufacturer confidence in durability.
Cons
- Some users reported a loud, high-pitched sound from the PSU even at idle, across multiple units.
- One user received a unit with loose components rattling inside the casing.
- The white version of the PSU still has a black fan and grille, which might not suit all-white builds.
- The included cable set has one 600W 12+4 pin PCIe connector and three 6+2 pin PCI Express connectors, which some consider conservative for a 1000W unit.
Dimension Scores
The unit is 80 PLUS Gold and Cybenetics Gold certified, with measured efficiency reaching over 95% at 50% load, exceeding its rating.
It features hybrid fan control for passive operation at low loads, but some users reported a loud, high-pitched sound even at idle.
It uses 100% Japanese 105°C-rated capacitors and a new OptiSink design for improved thermal performance, though one user reported loose internal components.
The PSU is fully modular and comes with flexible, all-black, individually sleeved cables, along with cable ties and straps.
Best For
- Gaming PCs with NVIDIA RTX 5090 or AMD RX 9000 series GPUs.
- Compact PC builds needing a 140mm deep ATX power supply.
- Users prioritizing long-term component reliability with a 10-year warranty.
- Quiet PC builds that benefit from passive cooling at low power draw.
Not Recommended For
- Budget PC builds, due to its mid-range price band and 1000W output.
- Users sensitive to high-pitched electronic noises, given reported coil whine issues.
- Strictly all-white aesthetic builds, as the fan and grille are black.
Watch Out For
- A user reported receiving two units that produced a 'loud high pitched dial up sound' at idle, and a third unit with rattling internal components.
- The 'white' model includes a black fan and grille, which can clash with an otherwise all-white PC aesthetic.
- While 1000W is sufficient for a 5090, some users on Reddit suggest a 1200W PSU for more headroom with future components.

What Buyers Say
The most surprising feedback is the recurring complaint about a high-pitched noise, even at idle, with one user experiencing it across multiple units and another finding loose components. Despite these specific issues, the PSU is praised for its high efficiency, often exceeding its 80 PLUS Gold rating, and its compact design. The inclusion of a native 12V-2x6 connector and a 10-year warranty are frequently highlighted as significant advantages for modern, high-power systems.
“Man, I really wanted to love this white PSU, it looks so clean, but the high-pitched whine was driving me nuts, even when I was just browsing. Had to send two back, and the third one rattled! What happened, Seasonic?!”
Common Praise
- The power supply is ATX 3.1 and PCIe 5.1 compliant, with a native 12V-2x6 connector for new GPUs.
- Efficiency is high, with measurements showing 91% to over 95% at 50% load.
- The compact 140mm depth makes it easy to fit into various cases.
- The fully modular, flexible, and individually sleeved cables simplify PC building and cable routing.
- The 10-year warranty provides confidence in its long-term reliability.
- The hybrid fan mode allows for silent operation during low power consumption.
Common Complaints
- Multiple reports of a loud, high-pitched sound or coil whine coming from the PSU, even when the system is idle.
- One user received a unit with loose components rattling inside.
- The 'white' version still features a black fan and grille, which can be a mismatch for all-white PC builds.
- Some users feel the number of included PCIe connectors is conservative for a 1000W unit.
Ownership Tips
- The hybrid fan mode actually works, keeping the fan off during light tasks, making the PC quieter.
- The flexible, individually sleeved cables are a dream for cable management, much easier to route than flat cables.
- The 12V-2x6 cable feels robust and securely connects to the GPU, no wiggling.
- The compact 140mm length is a real space-saver in smaller cases, leaving more room for other components.
- The white finish on the main body holds up well, but the black fan and grille are a minor visual inconsistency if you're going for a pure white build.
