What does the user manual (download it from dell.com if you don't have a printed version, your service tag might be useful to find it) say about the meaning of that light flashing yellow?

Now you have these lights.

In reply to: light is 3 and 4

And the service manual. What did it tell you this meant?

This is more of a discussion forum where it's like you have a flat tire and someone stops to help. You get to help too.

That aside, I own and soon will be moving out a HP d4999t and on the Watt meter I saw it barely top 200W draw so 305 should be fine if the PSU is good.

I plugged out the power supply

In reply to: Now you have these lights.

now PSU is in my hand i searched on internet about the reset button back on it and in Dell's video i came to know that if you press that button and keep pressing it the Green light should lit and keeps on until you move your hand away from the reset button in that case the PSU is fine . But if you press the button and the green light do not turn on its mean the PSU is out of order . but in my case the light starting misbehaving it turns on and of automatically the i have arranged a video of that you can watch it
Here is the link of my Video : Video of PSU 
Here is my power supply image : http://www.fkapowersupply.com/img/cms/J775R/J775R%202.jpg

I hope that information would be helpful ,

You are the PC tech here.

In reply to: I plugged out the power supply

As you have the manual and the results of the test. A PSU seems to be the right choice.

In a shop the PSU would have been swapped out and the PC re-tested. In a home environment you run into folk that demand the right part be replaced. It's not an unreasonable demand but to get there you would need a PSU tester which can run as much as a new PSU.

So there you have a PSU that seems to fail the test. What more is required? I can't give you the answer "it's the PSU" since you may hold my feet to the fire if I was wrong. You have to make that call. I think you're right.

It's not just about the Watts.

In reply to: Thanks

And here is where we step off the curb into a puddle. What a mess. OK, why did I lead with this?

The PSU Watts is just one parameter of the PSU. Some PSUs use split rails which is fine if you know to check the Amperes of each rail and know your PC in depth. But that's 1 out of 100 or lower. What to do to avoid this?

-> Answer. Shop for a Single Rail PSU model.

As to the Watts, here a 450 or 550 PSU is about the same price. As to the 305, the fact it failed points out that it was running at near or over full load. Just like your car, drive at 100 MPH and it will break down soon compared to driving all year at 65.

I understood but i am confused in something
Can you tell me what to read on the psu steaker i know now i have to buy 450 or 430 and even 400w psu but (rails)?
Where to check them and what nunber is required on my power supply many things written tell me what to read and buy psu
Im very non techinalical in that matter .

Look on side of PSU

In reply to: Thanks

If you see two ratings for 12V and it also has the Amps for each rail, that's a split or dual rail PSU. A single rail would have only one and preferably in today's world would be over 40 amps too.
