Antec Signature 1000W Platinum Power Supply Review

Conclusion and Verdict

The Signature 1000W is a great PSU. This thing is ready to handle the new gen of intel that is going to be power hungry or another 2080 GPU whatever your thing may be. Either way the platinum efficiency, solid construction and quality parts make this power supply a winner in my books. The zero fan is an awesome feature. I am not sure what the temps need to be to kick on but I played a couple of hours of Anno 1880 and the fan never came on? I could feel some heat setting in but it never had me worried. Or it came on and I just didn’t notice it because this thing very very quite even when the fan is going. Virtually silent. We don’t have any flashy RGB or custom paint but the subtle class you can see, makes this PSU worthy of being shown off in any system. The signature series has three different wattage options platinum 1000, platinum 1300, and titanium 1000. This line is definitely the top of Antecs power supplies.

One thing and the most important thing to remember when swapping out power supplies, IS NEVER REUSE CABLES FROM ANOTHER POWER SUPPLY! I would even caution this idea if its the same brand. I learned this the hard way because I didn’t want to re-cable a case and come to find out some power supply connectors vary brand to brand. Here is good explanation of what I am saying. Luckily when I did this I only lost some lights because the power supply was semi modular and that probably saved my mother board and CPU. Anyways take the time and use the cable that come with your power supply at all times!

The Signature Series is very new and limited on where you can find them right now but here are the prices point I have been able to find.
  • SP1000 – US$ 229.99 (Platinum) Signature 1000W
  • SP1300 – US$ 269.99 (Platinum)
  • ST1000 – US$ 279.99 (Titanium)

  • Zero fan
  • Platinum Efficiency
  • Stable Performance
  • Fully Modular
  • 10 Year Warranty


  • None


Final Thoughts:

Antec has been providing us with great power supplies for a long time and that continues with the Signature Series. The series has the looks of class and the performance any extreme builder would appreciate.
