Will my PSU be able to live long enough?

So recently I got a new computer. The only issue is.. it has a 400w PSU and is running a graphics card and a huge computer screen.

The graphics card is an ATI Radeon HD 5670 Sapphire version.

The computer screens resolution is 1900 x 1300.

The motherboard is a AMD Athlon II X3 3.10GHz.

It is also running speakers and a wireless keyboard as well as a mouse.

Do you guys know if the PSU will last long enough? It has been running for 3 days smoothly.

  1. And I forgot to add.. It's running 1 Cd/DVD rom drive and one 80mm fan on the side and a a 120mm fan in the front.
  2. You're fine the power requirements for that card are low.
    Easily under 200w in real world conditions.

    Single GPU 5670

    System in IDLE = 164 Watts
    System with GPU in FULL Stress = 222 Watts
    Difference (GPU load) = 58 Watt

    Dual GPU 5670

    System in IDLE = 175 Watts
    System with GPU in FULL Stress = 285
    Difference (GPU load) = 110 Watt

    Thank you very much for replying :) so does this mean I will not need to upgrade my PSU anytime soon? I also heard that a big monitor takes up about 80 watts. I'm kinda concerned about this. I want to make sure that nothing goes wrong.

    The monitor will draw power from the wall not the psu.
