im looking for a psu that is around 600-650w and as silent as possible, and stable and reliable at the same time.
i found out that its more safer compared to having a 1000w psu because it felt like getting my intestines got yanked out through the ass when i turned it on. literally i got scared of a 1000w due to flikering lights

More about : silent psu

Hi !

Well, in my opinion, Seasonic makes the best silent power supplies : the fanless type (up to 460w only). They are very reliable, and have good reviews.

Here's a link to the seasonic website (for the "updated" X-series, not fanless, but very silent) :

Here's a link to a review of the 650w X-series (the "older" generation) :

Hope this helps !

a 1000w psu will not pull more than a 600w at startup. it will only supply what your computer needs, so replacing a 1000w with a 600w ameks little to no difference in power cinsumption...if your lights are flickering because of your pc, get your homes wiring looked at before you burn the hosue down!

Do you have your computer running next to your bed when you sleep? Is your cooling setup passive (no fans/pumps)? Or why else would you need absolute silence?

If regular silence is enough - I'm happy with the Enermax 80+ gold rated PSU (Pro 87+ 500W, they have 600W etc). I've understood the gold-rated Seasonic would be just as good. In practice you will not be able to hear them at all even when the fans are running... case fans etc tend to be more noisy - if you have 140mm at 330RPM it's kind of obvious it can't be too loud :sol:

seasonic s12 is very quiet, oversize it a little and it'll never get hot enough to bother you.

And what PSU do you have.

Yes 1000W is serious overkill for that power wise.

Take a look at this thread and read the PSU suggestions, since your requirements are similar: I think you would be very happy with the low noise of the Enermax and Seasonic options, but your other components will be significantly noisier than these PSUs, so if you are on a budget you can consider the other options too.

Best solution

The Corsair VX 550 should be plenty for your needs.. And it'll give you adequate silence also..
