You sure it's 500W and not 550W? That DPP P10 model uses a more advanced, expensive design built with more robust components that achieves greater electrical output stability. Also I think it's a bit quieter.

They're both generally a bit overpriced for what they are. E9 CM's quality is not bad, but it's much lower than average for a power supply of its cost. The price comes from the Be Quiet name and paying the premium for the fan / fan control and modular cables.

edit: a lot of the power supplies you seem to be looking at include the Be Quiets and the Cooler Master VS (V semimodular) don't have passive fan mode. But if it's running the fan at a level that produces a similar noise level as say two Gentle Typhoons running 800 rpm, does it really matter? That's about roughly the idle level of stuff like Cooler Master V550S.

I don't know about the quality of the insides of the cheaper PSUs, but if BeQuiet are using one of their own fans in them instead of letting the OEM that's manufacturing the PSU choose the fan, they should be great for noise. The BeQuiet fans are the sort of fans that are weak and tuned to not make a "woosh" noise from air moving. They have a bearing that's not making strange noises.

I think I heard the cheapest BeQuiet PSUs do not have their own fans in them. You might be able to check what's going on by looking up reviews.

Yep, it's 500w. Bear in mind, i'm looking at swedish prices so that was a rough conversion off the top of my head.
EDIT:
Ah sorry, i'm a little loopy. it's 550w as you said.


And regarding your edit, i do know that, but it's hard finding information about units that run passive fan mode. If you have any suggestions where i should go about looking (without checking every single review of every single unit) or if you have any recommendations, i'm all ears smile.gif

Although yea, that's something i'm looking for. The quieter the better. It doesn't have to have a passive fan mode, but it's welcomed.

Alright, that's good to know!
