|"When I changed that setting in the BIOS I also changed another one.|
I had turned off the IDE controller because I haven't been using it and
it added a second or two to system startup. After turning it back on,
in three restarts so far, the video has not come on until the screen
notice that the IDE controller is in place."
"Monitor: Dell 2408WFP"
Apparently it's a 24 inch (diagonal) wide screen LCD monitor
You CAN experience a delay seeing the video of a CRT monitor while booting, but when you have an LCD (or Plasma) monitor, you should see video nearly right away while booting, (in both cases) as soon as the led on the monitor turns the color it is when it's receiving a video signal.
It not appearing nearly right away, in itself, MAY indicate your power supply DOES have a problem..
As I have said previously, you can eliminate or confirm the Antec PS as the cause of your problems by simply doing this...
"If you can borrow another power supply from a working system that has at least 450 watts capacity, try that for a few days. "
It may take a lot less time than that.
Your power supply probably has superior heat sinks. In that case, it's possible in theory that the PS fan does not spin when the interior of the PS is cool enough, however, I have NEVER encountered that or heard of that for ANY standard sized computer power supply, and I have found NO evidence that your model is supposed to do that !
I don't think you have mentioned how old the power supply is, as in, whether it was new or had been previously used when you built your present system. An older version of a model is more likely to always spin the fan, in theory.
Antec itself only has info about the current version of the model.
"500W Continuous Power"
Continuous rather than intermittent - good .
"...meeting the Bronze level of efficiency from 80 PLUS®,"
It's at least 80% efficient - good.
"On top of that, this EarthWatts power supply boasts universal input to automatically work on any power grid on the planet, and an 80mm fan to keep cool."
The fan is shown in the pictures at the back of the PS.
"....I can see the power supply fan without removing the side of the case, but it is difficult..."
It shouldn't be - if there is good enough lighting, it would be obvious when it's not spinning at the back of the case.
two +12v output sections
"3 year warranty"
Good, and good.
Although, some say a single +12v output section is sometimes a better situation.
Antec's higher line of PSs have a longer warranty.
How does a PWM fan affect fan speed and quiet?
Pulse Width Modulation (PWM) technology finely controls the speed of a power supply’s fan.
By using this method instead of traditional voltage-controlled fans, this type of PSU fan can run up to 50% quieter than standard fans. A PWM fan can run as slow as 10-15% of the fan’s rated top speed, whereas a voltage-regulated fan can only go as low as 40%. "
NO mention of it ever NOT spinning, or 0 (zero) rpm.
If you replaced the fan and connected it internally, it probably must be a PWM compatible fan. A case fan wouldn't requre that if you connected it to a mboard fan header. If the mboard doesn't have a spare fan header, you don't need 3 other case fans.
scroll down - shows they use double ball bearing fans.
You're not likely to have a problem with those bearings / the fan(s).
"The fan rotates easily when I push on a blade. No sign of friction."
So - your problem may be in the control circuit(s) for the fan.
"It wiggles back and forth when it stops turning, which suggest to me
that there is no sticking."
I recently replaced a fan in a Cooler Master PS that did exactly that, all the time - it never spun. It was on a friend's computer that I had worked on before - previously, it spun all the time, though it was probably temp controlled and spun slower when the PS was cooler.
I replaced the fan with an Antec case fan, dual ball bearings, a speed control in it's wiring, connected to a fan header on the mboard - that cooled the PS fine.
The same PS failed to fully boot the same computer (with the same Sapphire HD 4850 card, by the way) a short time later, probably because the PS had gotten way too hot when the fan wasn't working and had damaged itself.
The same system worked fine, and still works fine, with a new replacement PS.
I checked out the specs for the Cooler Master PS model on the Cooler Master web site - the single original fan has two cheap sleeve bearings. The warranty period was not stated but when I searched on the web I found it was only one year.
The original fan still moved easily enough, but it doesn't take much friction in the bearing for the fan to NOT initially start spinning when it's supposed to, so I assumed the bearings were in the process of failing.
It could very well be the bearings hadn't gotten to that point yet, and the actual problem was the control circuit(s) for the fan was malfunctioning !
Nothing concerning whether the fan ever stops spinning in that.
Older info .....
antec earthwatts fan not spinning? does anyone have this psu?
"my earthwatts 380 psu's only fan is not spinning
does anyone have an earthwatts, and does the fan spin when idle? "
My note - the 380 watt version is in the same series.
"anyway, I received a replacement earthwatts 380 psu from Antec, and the fan spins even when cold.
i still question the reliability of this unit though."
Review of what may be an older version of the model.
(sometimes model versions are not changed at all over time)

"The EarthWatts is 80 Plus certified; meaning that it has 80% or better efficiency at 20%,
50% and 100% of the power supply's total capability."
Searched the page for: spin, then not spin
He does NOT mention the fan NOT spinning - he only mentions that it DID NOT SPIN UP, as in, it did not spin faster, until it had a greater load on it.
"Interestingly enough, although my temperatures in the hot box were well beyond what they ever were in the cold box, the fan did not spin up and was not audible until test 4 again!"
"And once again, the fan did not spin up to full speed until test 5."
"As I said in my second post, the computer has six fans. The PS fan
and the 120 mm exhaust fan in the rear were preinstalled. One fan
is on the video card, the CPU fan is 92 mm, and two 92 mm fans
blow into the front of the case."
It's NOT a good idea to have more case fans running than you need to be running.
If you have too many of them running, you're just introducing more dust and lint to the case interior and you will need to clean that off of your fans and heat sinks and mboard more often.
Only have one or as many running as it takes to cool the interior of your case to a minimum.
You have a decent CPU fan and heat sink going by what you've said.
You probably don't need any more than one or two case fans to be running. You certainly don't need two fans blowing in at the front of the case.
"The CPU fan and the front fans are controlled via the motherboard."
Some mboard's bioses can vary the speed of the cpu fan, but I've never seen one that can vary the speed of fan connected to a fan header for Case or Power fan.
"I thought the max recommended temp for the CPU was 40 deg C."
"Motherboard: ASUS P5Q-E"
Five listings for Q9550
Intel part numbers in blue on the left - clicking on those shows the specs.
The first four -
Minimum/Maximum operating temperature (°C) 5 - 71.4
Minimum/Maximum power dissipation (W) 12 (TDP in extended HALT state) / 132.48
Thermal Design Power (W) 95
The last one...
Minimum/Maximum operating temperature (°C) 5 - 76.3
Minimum/Maximum power dissipation (W) 12 (TDP in extended HALT state) / 132.48
Thermal Design Power (W) 65
Your max operating temp - the temp beyond which the cpu will "misbehave" - is probably either 71.4 or 76.3 C.
