I had an antec basiq 430W and a corsair CX 430W psu in my computer. They both were very loud. I could hear the whining everytime.... I want a quiet PSU. Please reccomend me some. Also, I would like the psu's to be Antec or Corsair because I love those brands.

You could buy a quieter fan and install it in the PSU, if you don't mind poking around in there.

If your system is not overly power hungry, many newer seasonic and seasonic based corsair(and some XFX) units have a hybrid mode that shuts off the power supply fan at low loads.

The down side, are mostly 600+ watt units.

They also have some passive power supplies on the market.

I did a fan swap on 2 FSP power supplies(and an OCZ made by FSP) with no negative effects so far.

I always found my HX850 to be quiet(and my EA 650 to be LOUD). Then i got some low speed Noctua fans and found while quiet, it is still not silent(but runs very cool). I myself have been looking at some of the new hybrid power supplies, but it is not in the current budget.

What kind of power usage, and what is your price range?

Corsair's reputation came from selling Seasonic manufactured PSUs. I have the Seasonic X650 gold with a variable speed fan. Its so efficient that the fan almost never turns on, and when it does its near silent. Highly recommended. There are cheaper and more expensive versions too.

I have 3 Antec power supplies. 500W EA which I've had about 5 or 6 years, a 650 EA Green, about 1 year old and a 750 W HCG I've been using for 5 months. I can't even hear any of them and the rig w/ the 750 W sits 2 ft. away at ear level.

In defense, my EA 430 was dead quiet, but always had a very low load. The 650 was quiet with a lower powered system(it idled at about 40 watts and loading at about 140-160)

Get a more efficient PSU - generates less heat - needs less fan or no fan.

amiffin - jonnyGURU SAYS "The fan was loud at full load and left us wondering why PC Power & Cooling didn't switch out the de-facto Adda 120mm fan for a quieter 140mm fan, especially considering this is for the "Silencer" product line. All and all, is this power supply "superior" in any respect?" about the PC Power & Cooling.

Moose, that Stryker 500W PSU you linked. Apparently they feel pretty confident if they can offer PCI-Express Connector2 x 6-Pin, 2 x 6+2-Pin with a rating of +3.3V@20A, +5V@20A, +12V@41.5A, -12V@0.5A, +5VSB@2.5A
in a 500W unit with no fan.
I wonder what would happen if they plugged in a pair of GTX 580's?

This is one of those situations where it's not necessarily true that if the PSU has enough connectors it will run the cards.

I'm interested in the 500W-600W power supplies and the price range can be between $40-$70.

and no, my computer isn't power hungry. It only has a 4670 radeon Hd and a hdd and a dvd/cd burner.

In that case my suggestion is this:

I have it in my home theater PC that stays on all the time. Stays quiet and cool.

@nukemaster
I am using an amd athlon II x3 435 processor. D:

@deadlockedworld
Thanks! It seems to be good. Are there a lot of unneeded wires? And the wires are hard to bend? I read people having those problems on newegg.

@davcon eh I rather get the 500W Antec Earthwatts, but I don't know the noise level on there.

The Antec Earthwatts EA-500D uses an ADDA AD0812HS-A70GL, which is an 8cm sleeve bearing fan with a maximum fan speed of 3200RPM.
This is the same fan that is used in the Antec Basiq 430.
Fans on Antec units usually get 'noisy' at about 80% load, which also seems to be true for a lot of Seasonic units.

The fan used in the CX430 V2 is a Yate Loon D12SH-12, which has a maximum speed of 2200RPM.

The Seasonic S12II Bronze 520W uses an ADDA AD1212MB-A70GL, which is a 12cm ball bearing fan.
This review shows the fan speed curve for it.
http://www.xbitlabs.com/articles/cases/display/seasonic...

The Silencer MK III 400W uses an ADDA AD1212HB-A71GL, which is a 12cm ball bearing fan with a maximum speed of 2200RPM.
The low wattage (500 & 600W) Silencer MK IIs on the other hand use Globe Fan dual ball bearing fans with a maximum fan speed of 1500RPM. Unfortunately I don't think they are available anymore.

OCZ ModXStream Pro 500W, 600W, Rosewill Hive 650W use a 13.5cm sleeve bearing Globe Fan RL4Z S1352512H, 0.33A which has a maximum speed of 1500RPM.
OCZ ZS series basically uses the ball bearing version of the same fan, which is the same one used in the PCP&C SMKIIs.

So you can either choose an Antec, Corsair, Seasonic unit and make sure you don't load it up to 80% or you can buy something which shouldnt' be that load even on full load.

Rosewill Capstone 550W 80Plus Gold $80
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
If you are prepared to go over your budget then this is likely to be unbeatable.
It is based on the Super Flower Golden Green platform, which is quiet even on large wattage units (up to 750/850W).
If it is like the 550W SF Golden Green unit it is based on then it uses a Globe Fan RL4T B1402512M, 0.30A which has a maximum speed of 1200RPM. However the fan speed on maximum load on a lot of SF GGs based units have been measured at below 1000RPM.

I think it is highly unlikely that the Styker 500W was designed to power a system with two GTX 580s considering that Nvidia recommends a 900W PSU with a current rating of 62 Amps or more.

Meanwhile the Stryker 500W is a very high quality unit:

Honestly, yes there are quite a few unneeded wires. I did manage to wrap them up and tuck away in an xbox-sized home theater PC case though - so im sure you could manage as well.

The modular versions of it are awesome, however more expensive. The closest seasonic modular (SeaSonic M12II 620 Bronze 620W) is $89. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
