Alesis Fusion PSU . . .

Unread post by parametric » Thu May 25, 2017 12:54 am

Following Jesse's revlation about no more PSU's here: http://promusicproducts.com/forum/phpBB ... 161#p36158

I sought out InMusic here in the UK today . . . [InMusic Brands (Europe) Tel. 01252-896-040]

The phone was answered directly by a Human (Y) (I forgot to note his name) :roll:

I explained that the part - (Alesis Part no. 9-79-0361) and (Akai Part no. SPSHA33R4-058N) are for the SAME PSU which is

common to the Alesis Fusion (6HD and 8HD) AND the Akai MPC5000 . . .

(A number of other parts ARE common too)

He confirmed the commonality AND the fact that they had stock - so I ordered a "spare" for both my Fusions . . .

With carriage and VAT they will be £80.03 Each - which is amazing - considering I've seen prices Stateside

of $145 - $175 for ONE, probably plus shipping.

So I HAVE to report - excellent response and Service, here in the UK . . . . (Y)

NONE of that "Press one for a ten minute wait - press two to hear a list of ALL the products you're NOT

interested in" CRAP . .

The PSU has been a problem area for the Fusion - especially the 6HD - together with reports of hot running,

often leading to failure . . .

The SSD upgrade does alleviate this significantly by lower power consumption and less heat produced . . .

So best advice is to put one by JUST IN CASE . . . .

I mentioned the apparent shortage at InMusic USA - and he claimed that spares are common across their

three Primary MAIN Offices - So I don't know WHAT is going on . . . 8O

Thanks for that info Chris. It's a shame that there were these issues around the psu in the Fusion. I never had any problems with mine and I "think" I had three of them, all the 6HD. It does get hot along that right hand side though so perhaps if I had kept them longer this may have become a problem. The 8HD of course has a lot more air around it due to the larger case.

Precisely Saul,

everything is more closely packed in the 6HD. The later PSUs were a (partial) redesign - sporting slightly longer "cooling fins" (on

one side at any rate) - though I always got the impression that it ran close to it's limit - and therefore ran hot . . .

This is why I feel that the SSD upgrade was GOOD for the PSU - as current demands are lower than a HDD - therefore it runs

cooler . . .

That has to help too, with a gentler thermal cycle between "Uses" (Y)

Are those parts the newer PSU ?

Same problem with the EX5 PSU. Yamaha no longer sell replacements or repair them and neither do their approved UK repair company.

On the plus side the Yamaha A3000 sampler uses the same PSU (and SCSI) card, and you can pick them up for peanuts, which is what I did to resurrect my EX5 with failed PSU. The fall back would have been to purchase a 3rd party tri-volt PSU and get the drills and hacksaw out!

Hi, I just wanted to say that I’ve successfully ordered a new PSU from InMusic.

My 6HD has the old design, very very hot.
I get scared easily so have bought the replacement, even though my fusion works fine.

If it’s still too hot, I’ll try the PC fan and pop bottle fix.

My old fusion never got that hot so I’m hoping this new power supply will help.

That's a smart move <xanderbeanz> . . . .

As soon as heard that InMusic had them in stock, I ordered 2 - as I have an 8HD and a 6HD.

Both are currently fine with their original PSUs, but I didn't want either to become a paperweight for

lack of a replacement . . . .

Both have maxed out Ram AND the 120Gb SSD conversion, which I would recommend particularly as

the SSDs run cooler than the original HDs . . .

Both the new PSUs have the redesigned (slightly larger) cooling fins.

Here's some pics I took when they arrived . . .

Thanks P.

I just wanted to mention a couple of things.

So my 6HD, which I’ve had about 2 weeks, is already maxed out with SSD...however, it gets very hot on the right hand side. I don’t know if you find this too?

So I ordered this power supply...I don’t remember my old Fusion from years back getting that hot. Do you think I could gig with it like this?

Anyhow, it arrived, I opened her up, and it looks like this new power supply is the same exact design as the old one.

So, my question is, when I take it to the tech, should I:

Option 1: Keep the new power supply as a spare and just get him to install a fan + a piece of lemonade bottle as a cooling system? There’s a cool guide for that hack on this site.

Option 2: Get him to change the power supply AND install the fan.

Any advice would be appreciated.

PS, when I opened it up, a little black and red wire running from underneath the keyboard, up to the top of the case, to some pins below the knob/wheels board, came out, and the pins kinda got bent, I guess I didn’t open it slowly enough.

Anyhow...I looked inside and thought “this is too much of a job for me, I’ll go to the tech” and then bent the pins back, and put the wires back where I THINK it went.

The system booted fine, all knobs work, So, does anybody know what this little thin black and red wire with plastic connector does, and maybe you might have a picture to show me exactly what orientation this wire plugs in?

Anyhow, thanks. I really want to have a fully upgraded, colder running fusion, this has been causing me a little anxiety and restlessness to tell you the truth.

Anyhow, thanks.

To my knowledge, the 6HD has always tended to run hotter than the 8HD - largely due to the fact that

the 8HD has more space to lose the heat.

Probably the PSU should have been better designed. Such heat can't be good for the Caps . . . . .

If the Heat Sinks on your new PSU look the same as the one in the 6HD, then you already have

the later redesigned one installed. (The original design had noticeably smaller "Fins")

Get your Tech. to confirm that the voltages are "correct" and it should be fine to leave "as is" . . . .[/quote]

I think you mean THIS cable?

P1010050.JPG

This cable catches most people who open their Fusions. It clearly must be unplugged to properly open

the Fusion up.

I don't remember what it actually does, or if the socket is "keyed" in any way to ensure correct insertion.

As you have reassembled yours - and all seems to work correctly, I would suggest it IS the right way round (Y)

Next time you have it apart, I would take a felt-tip and label the socket with "R" and "B" so you never

have to guess again . . .

Marcello's extra fan looks to be a great idea. Others have suggested Drilling holes in that end Panel to

help the airflow of the original fan. It rather depends on your views on "keeping it ORIGINAL".

For you own peace of mind, I would suggest that it really needs to be running cooler, before you consider

gigging it.

Thanks.

For reference, that is the little red and black cable. There are holes ob one side of the plastic plug, where little copper bits are showing through the holes, I connected it with these copper holes showing upwards.

Thanks for the tips, I will make my tech, Steve, a guide with the checks you’ve suggested and also give him the lemonade tunnel fan mod pdf.

I have ordered a suitable fan and a variety of molex+3pin extenders for any eventuality so hopefully it should be a quick job.

I think gigging the Fusion as is (or at least going to band practice) would be ok once or twice, as our sets are usually only 30-40 minutes or so, and it hasn’t got that hot by then, but yes, it’s my priority to get it looked at.

It’s so odd, my old fusion never got hot, maybe it already had had a fan installed?

For reference, that is the little red and black cable. There are holes ob one side of the plastic plug, where little copper bits are showing through the holes, I connected it with these copper holes showing upwards.

Thanks for the tips, I will make my tech, Steve, a guide with the checks you’ve suggested and also give him the lemonade tunnel fan mod pdf.

I have ordered a suitable fan and a variety of molex+3pin extenders for any eventuality so hopefully it should be a quick job.

I think gigging the Fusion as is (or at least going to band practice) would be ok once or twice, as our sets are usually only 30-40 minutes or so, and it hasn’t got that hot by then, but yes, it’s my priority to get it looked at.

It’s so odd, my old fusion never got hot, maybe it already had had a fan installed?

That's a smart move <xanderbeanz> . . . .

As soon as heard that InMusic had them in stock, I ordered 2 - as I have an 8HD and a 6HD.

Both are currently fine with their original PSUs, but I didn't want either to become a paperweight for

lack of a replacement . . . .

Both have maxed out Ram AND the 120Gb SSD conversion, which I would recommend particularly as

the SSDs run cooler than the original HDs . . .

Both the new PSUs have the redesigned (slightly larger) cooling fins.

Here's some pics I took when they arrived . . .

Hi P,

My tech came back off holiday, so I bought all the parts and am getting him to do the fan and pop bottle mod, and also check the voltages given off by the PSU.

It’s with him currently so I’ll report back when he’s done.
