anyone got a really quiet psu to recommend . must be at least 400w . itd be really good if it was quiet , black with blue led. but i aint that picky , a really quiet one will do . and pops i see what you meant about muffling noises , it is only really the psu thats noisy .
for every aspect of your problem. You already have one running on silencing your computer, and this is just an extension of it. Please stick to one thread in future to avoid confusing people - I'll lock your other thread now.
i thought that a thread was meant to accurately describe your problem , and as such i marked the other as resolved (as many dont) and then started the new one hoping that people who didnt post to the (sound proofed case) may have some input on a quiet psu .
