Andyson 300w power supply

davids · Post by **davids** » Thu Jan 17, 2008 9:24 am

Hi

The cheap Andyson AD300AS PS is spoiling what is otherwise a fairly quiet desktop PC. Its audible from power up and gets worse after a few minutes no matter what is being done.

Quick question- can I disable or replace the fan or would it be best to replace the whole PS?

System is:
M/B: MSI RX480M2
processor: Athlon 64 3000+
video: ATI X800 (with ZalmanVF700-CU)
80GB and 300 GB hard drives

Specs for the Andyson are:
AC 115/230v 5.6/2.8a 47-63HZ
max 180 watts

Thanks.

You shouldn't completely disable an actively cooled PSU's fan. It's what keeps it from overheating. Instead you can try lowering the RPM or replacing the fan with a quieter model. There are good articles here on the forums, and here's the sticky on modding PSUs: viewtopic.php?t=13289

Thanks!

Actually, a while ago, I fitted two Panaflo's FBL08A12Ls (intake and output) so could swap one of them for the one in the PS, I guess? But before I do, here's what Speedfan is telling me:

Ambient: 35
Remote 1: 41c
Remote 2: 118c
HD 0 (80GB): 41c
HD 1 (300GB): 44c
Core : 39c

Personally i would just replace it. The fan may be the only thing bothering you now, but cheep PSU's typically fail sooner, and have horrible voltage stability. Save yourself some headache down the road with an unstable system, and replace it now.

Check out the recommended PSU list. About the quietest PSU you can get is the Corsair VX450.

Fixed that for you.

There are a good number of fanless PSUs which will do just fine for that type of system load if you really want quiet. The recommended PSU list as Aris suggests is a good place to start.

Hi

Yes, quite prepared to replace the PSU completely, if need be.

The Corsair VX450 isn't too expensive, I guess (Â£40). Will it be an easy-to-fit drop in replacement?* And will it be something I could easily keep for the next PC I buy, as my current one is about 3 years old?

*My PC is micro-ATX http://global.msi.com.tw/index.php?func ... incat_no=1

Edit: I'll probably give a fanless PSU a miss for now. The airflow in my cheap PC case isn't great and I'm not really confident enough to have a dig at it.

Is your current PSU ATX form factor? If so, the Corsair will drop right in. When building a future rig, the Corsair should also work just fine.

If cost is an issue, there are other PSUs on the recommended list which are also very quiet and could bit less expensive (look at the Seasonic units).

Well just had a look at it. It says 'ATX power supply' on it so I guess its going to be the same size as the Corsair. Suppose my PC must be using an ATX Psu in a micro-ATX case and mobo.

The Andyson website is in Japanese so cannot check.

I recommend measuring your current PSU before buying a new one. ATX PSUs are 150x140x86mm (WxDxH), mATX are significantly smaller.

Just measured it- its the same size- so game on. Thanks for your help!

If the Andyson is max 180w I reckon you should think about a psu with an external brick. See the threads about the pico supply. I'm using an mCubed 200w (it says 280w peak) which you can see here: viewtopic.php?t=43893

I've had it 3 months with no problems, it was dead simple to install and is silent. I love it (well... maybe "love" is putting it a bit too highly for an inanimate object)! The good thing about an external brick is it solves your heat problem by moving the heat outside the case.

Cheers- just found it here:

http://www.quietpc.com/gb-en-gbp/produc ... x-ef28-psu

But its double the price of the Corsair and more than I'd like to spend really- although temptingly silent. My Andyson is a 300 watt PSU (not sure why is says max 180 watts). I think the Mcubed external PSU is designed more for its own mini case because it says:

1. For Mini chassis only

potsy · Post by **potsy** » Thu Jan 17, 2008 3:43 pm

Yep, it is a bit steep - but at least you get to buy in pounds sterling. Multiply by 2.6 for the price in poor old Aussie dollars! I think the shape of the circuit board might be designed to fit in the mini chassis, but it comes supplied with a plate which fits any case - that black plate you see in the pictures of mine just screwed into the stock holes in the Fusion case. Otherwise its just a PSU I think.

Sympathies over the Aussie dollar conversion!

I'll have to think about it.

Ok, I want to buy the Corsair VX450W but it has its fan facing downwards while the existing Andyson has it firing out the back of the PC. Will this be a problem, I wonder?

the Corsair:

No, it won't be a problem.

I hear you- but difficult to see how it will be able to fit in, with socket/switch exiting PC correctly, unless you fit the Corsair on its side. Yet, looking at the Andyson from the inside, it doesn't appear to be on its side. Must say, I'm confused.

your current psu is ATX-compliant. your new PSU is also ATX-compliant. if it's the same size as your old psu, why would it not fit?

davids · Post by **davids** » Fri Jan 18, 2008 5:15 am

You're right- it fits- can see it now.

QuaiBoy · Post by **QuaiBoy** » Sat Jan 26, 2008 10:44 am

That looks like one of those stupid cases that have a PS cutout exactly the size of the stamped fan and power cable on the back of the PSU. You might have to take a tool to the back of the case (tin snips, metal nibbler, blow torch, in order of case thickness) to get any standard ATX PS to fit properly. Otherwise, you're good to go.

Good luck.

And also, I'd take a shot at modding the stock PSU. Maybe after you get your new one you can fiddle with it and have some fun. So it blows up, big deal. If it works out it's a nice spare.

And the quietest PSU with a fan you can get is the Seasonic S12 430W.

Sorted it out, for both of you

Personally, I'd get a new case with a quiet PSU built in.

Maybe an Antec 3800 or something, it's just a 3000B with a 380W PSU built-in.
