Zero RPM psu on low load, low wattage, lowish price

I'm looking for a low wattage PSU that doesn't engage its fan on when the system isn't at load. The problem is that google only really gives me PSUs with ridiculously large wattages for my intended use case.

No, you want a PSU with a good fan and low RPM (500rpm or lower).

The ones that come to mind are Cougar LX (too expensive), be quiet Pure Power 10 (400W and up), Straight Power 10 and 11.

 

And surprisingly Xilence Performance A+ and X, though the other ones are better...

 

Semi Fanless doesn't give you anything if the manufactorer didn't cheaped out on the fan...

Sadly there are no good quality PSU under 400W on the market right now.

And if there were, they wouldn't be any cheaper than the 400W counterparts...

Can we have specs? Can't recommend a PSU wattage without knowing the pc's power draw.

Most of the PSUs that I'm aware of that don't turn on the fan until a certain load are the Corsair AX series, and (IIRC), the RM/RMx series.

 

But it's true, most PSUs that have this feature usually output higher wattage.

A 65W CPU (Either ryzen 2200g or 2400g), 2 sticks of crappy DDR4 ram and an old crucial 400 ssd I have in my drawer.

 

I'm more or less aware of the needed wattage, I just don't really want to buy a 500W+ psu for this potato just to have it be silent on me.

PSU's fans don't come on based on load - they come on based on how hot the PSU is. So as long as the PSU is cool it won't need to spin the fan loudly.

 

The Corsair CXM has a pretty quiet fan. If you're using a dGPU-less system then it's a good pick for you.

The lowest wattage one I can find is 450W. That seems a wee bit overkill, considering.

 

Honestly, ideally I'd like one that's pretty much passively cooled.

Does it matter if it's modular or not?

Passive PSU's (EG: Silverstone Nightjar (or some similar spelling)) tend to be very expensive. So it's probably just better to spend 40-50 on a 450w CXM rather than 130-180 on 400-500w Passive PSU. (The cheapest one I could find is a 115 USD Seasonic unit.)

I don't care about modularity in this specific case. Noise and price are my only real considerations. If I can't find anything better, the CX450M will have to do.

The Pure Power 10 400W should be fairly quiet. It doesn't have a passive mode, but it uses an actually decent fan. Look at Cybenetics' testing for numbers
