Need quieter PSU for my system

Post by Perrezot » Mon Mar 04, 2013 8:13 am

Hello SPCR members!
I'm a first time poster, long-time reader of this terrific website :)

I've learned a lot and I assembled a new PC recently, its all nice and quiet except for 1 thing : PSU

PC:
Intel i7-3770K
32 GB DDR3 RAM
1 SSD 128Gb
1 HDD WD Green Caviar
Asus GFX 660ti dc2u

Case = CM Silencio 550
3 Noiseblocker fans

Atm I have a Cooler Master Silent Pro M2 650W in this system, I think it's overkill, and it's making noise when I stress my CPU.
So maybe I could try a fanless PSU for this system? Is my case good enough for a fanless PSU? (not really good airflow)

Cheers! :)

Welcome to SPCR. Your system's stressed load power is in the 280W range and pulls maybe 240W in heavy gaming. So, yeah, you could pop a fanless 400W 80+ gold rated PSU in there if you wanted.

Is the PSU noise fan-related or electronic buzzing or...?

It's some kind of wooshing sound, so I think its due to turbulence...
