Special Features

SeaSonic Power Supply

Ultra Tight Voltage Regulation
Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and 0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 PLUS load conditions) results in smooth and stable operation.



SeaSonic Power Supply

Seasonic Hybrid Silent Fan Control - S²FC & S³FC *
The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent, and Cooling Mode. In addition, there is a switch provided to allow for manual selection between the Seasonic S²FC (fan control without Fanless Mode) and the S³FC (fan control including Fanless Mode).




SeaSonic Power Supply

Benefits:

  • Reduces noise without increasing temperature.
  • Extends fan life by eliminating unnecessary rotation.
  • Optimizes heat dissipation at all times.
  • Fanless Mode provides unsurpassed silent performance.

New Feature: Hysteresis is achieved by a fan control IC, which optimizes how frequently the fan switches on and off. At 25 °C ambient temperature the fan turns on when the load rises above 35% (± 5%) and it turns off when the load drops below 25% (± 5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.



SeaSonic Power Supply

Dual Copper Bars
These pure copper bars conduct high current more efficiently to reduce impedance and minimize voltage drop.

1 out of 5 eggsDefective product

Pros: 1, Very cool cables.
2, It seems like a new, unused product.
3, Seasonic-famous-brand

Cons: 1, Before I received this item, I had been worried about if the new PSU was powerful enough to boot my system up. However, I found that I thought too much after I got it. THIS ONE DOESN'T WORK AT ALL. I tried to unplug every part of my machine and test it again and again. At last, only CPU, MB and one video card were remained and it still didn't work.
2, The tool and Seasonic logo which are included in Seasonic P 1000 are not included in this premier product. In one word, it worked for 0 sec.

Other Thoughts: Before I decided to buy this one, I was confused since Newegg said it had just 1 year warranty. On the contrary , Seasonic official web declared that it had 7 year warranty. Now, I think I know the reason.

My computer is sleeping and I am not able to continue my work because no PSU.

I still trust the quality of Seasonic products regardless of this experience.

Manufacturer Response:

Hi JingXue,
I apologies for the inconvenience this issue has caused you. Have you rectified your situation via the NewEgg RMA or direct with Seasonic USA?
The warranty on this product from us, the manufacturer, is 7 years. If you have any qauestions, please contact us at newegg@seasonicus.com. Thank you.

5 out of 5 eggsSeasonic Platinumm 1200w

Pros: Quiet, Plenty of extra cabling, clear and precise labeling for the CPU, PCI-E, Sata, etc. Very snazzy case. Went from 650w Power supply to this and performance picked-up immediately. Rig: ASUS Rampage IV Black edition with Intel i7-4960, 64 of G-Skill ram, ASUS GTX 780 Ti, 4 HD and 2 SS HD.. Will be adding second ASUS GTX 780 Ti in SLI.
Neptune Water cooler for CPU in Cool master HAFF 963 case with plenty of fans.

Cons: Had to pay for it.

Other Thoughts: Went to ASUS sight to calculate power requirements prior to Purchase. This is well over their recommendations with the 2 video cards.
