    depends on the noise. maybe the fan (its a ball bearing type and they can go dry or wear out). maybe something else.

    if you take out the fan and try oiling it. rp7 or singer oil or somesuch. dont want it to drip on the components, but ive read that some people do this with some success. and others without success.

    Wow I didn't know it was released 2005. I'm surprised the connectors work with my mb and gpu!

    I guess I just know very little about how to choose a PSU, and what connectors I need etc. I want a low wattage to make use of the peak efficiency right?

    that's the rule of thumb. 450-550W supplies are all most people need.
    even less.
    therell be a bunch of opinions, always open to suggestions.
    rm550w corsair is a nice one. (80plus gold) overkill but a nice warranty and quiet operation.
    there are others.

    the small form factor psu's from corsair are highly regarded by some.
    SF450 for example. 7yr warranty.

    I am keen on quiet. I sit next to my PC. Even tho I supposedly have quiet case fans I can hear the wind.

    So many ATX PSU are high powered. I have ATX case/MB, does that mean I can't use SFX/TFX form factors? They'll leave holes in the back of the case?

    yeah. adapter bracket required for sf.
    i think the 550 one has a fanless mode. the tests show it is quiet. "virtually silent at low to medium loads"
    fanless psu's are usually expensive.
    2 cents :)

    bitfenix do a "whisper m 450W" but hard to find in australia.
    antec ea 450w also hard to find....mm discontinued...owell.

    slightly cheaper; 7 yr warranty.

    Most likely. Not dangerous or indicative of failure.

    Still, a new PSU is pretty cheap. No harm relegating the current one to "spare".

    Set my beard. I tried to open the case to see where it comes from but it's so high pitched I can't really be sure. But I noticed that as soon as I press shut down the sound stops , even before the computer actually shuts down. It seems to also leak audio to my speakers.

    coil whine?
    um can you pin point where the noise is?

    sounding less like it is the fan...
    make a little vid of it on your smart phone maybe....

    just have to use your ears...close to each part. be careful not to touch them of course :p

    Old Antec Neo HE 430 is likely a rebadged Seasonic anyway, you could lookup the UL No. on the side of the PSU if interested.
    +1 for getting the SeaSonic 550W Focus Gold to replace it anyway - to go with the rest of the nice new system and keep the old Neo as a spare.
    I got about 8 years out of my old NEO HE 550 before it went bang, when it died it didn't kill any other components though.

    As to the noise, does it sound something like what's in this video?

    particularly like with the pitch changes between about 0:13 and 0:19

    The same can be said for your psu

    Really getting close I'm pretty sure it's not the GPU. It does seem more like coil whine, it's kinda similar to what EclipZ posted.
    It's higher than the GPU, so that's either the CPU area or PSU.

    I have oiled the PSU fan anyway, it didn't make a difference.

    Sometimes the whole rig runs silent, sometimes it does that whine. Could it be software triggered? In any case I'm looking at a new PSU. Nice easter break eh.

    as you're fairly convinced it is psu.
    just take it out of the case. and do a test. sit the psu outside the case. connect the power to the motherboard and gpu and fire it up. should make the noise easier to isolate.

    Looking at the

    be quiet! Pure Power 11 500W CM which seems to say it's quieter but it's 2cm longer
    vs Seasonic SSR-550FM Focus 80+ Gold since I don't think there's much time I need the fanless mode of the plus for +$20.

    It is so easy to test.

    - Open side of case,
    - Turn PC on,
    - Stick a toothpick into the PSU fan (or something wooden like a skewer, chopstick - DO NOT USE METAL) and stop it, does fan noise stop?

    Fan bearings do dry out, get old and or just start to whine a bit.

    It is 'very simple' to fix to either lube the fan or just swap it out of the PSU.

    Don't waste money on new gear unless you like to.....................

    Youtube video was just a decent example of coil whine I could find (based on what I've heard personally for noisy coils) to see if that was the same noise you are hearing, not necessarily pointing at video card as the source.

    Yes it could be software dependent - in so far as coil whine should be more pronounced when the system or particular component with the vibrating coil(s) has more load.
    Running a Linpack stress test might help make the noise consistent and help track it down if the noisy coil(s) are within the PSU or on the mainboard, as would taking the parts out of the case and running with minimum components to isolate.

    Exactly. It's the lifeblood of the pc....why not shelve out a bit extra. Relatively inexpensive bit of gear when people fork out huge amounts for other bits.
