I hate my ocz psu

[Eddie3dfx]

I have a 700 wait ocz that sounds like a vortex.

I have 2 options.

1. Replace fan with a 44cfm yate loon and risk overheating.. or

2. Modify it with a waterblock :)

So then I stumbled onto this page..

What say you?

Now here is what the inside of the OCZ looks like

Watercool that bitch...:up:

I wouldn't trust having water inside a PSU. What I think is the best method is to have plates glued to transistors and linked with heatpipes to the outside where another plate will be in contact with a waterblock. Like that, if it ever leak, it will be outside the powersupply.

From the picture of the ocz, I don't think it would be too difficult to accomplish that actually.

There is certainly enough room on the top to have a long block... I think I have one in mind..

I should pop open the ocz and put temp sensors onto the individual metal pieces..
This way I would get any idea of how hot the aluminum gets..
Your idea is good.. Use copper plates to hook up to the transistors..
Then on the top, solder on a flat copper plate so they are all touching.. On top of that a flat hardrive block.. (ones that u see go under the hardrive)
This way the entrance and exit are near the front.

I had the same problem with an Ultra X3 1000W. I like the thin black modular cables. All the reviews said it was "so quiet". What bullshit.

I guess everyone has a different definition of quiet. It uses a screwed up size fan, like a 130mm which you cannot find. I tried a 140mm, but no go on fitting right.

I opened it up and put a 12V to 7V resistor. Fan would not even start. I then changed to a 12V to 9V resistor. It started, but was still too loud for me.

I finally went back to goold ol' Seasonic M700. All single rail and handles my SLI no problem. Really quiet.

If anyone wants an Ultra X3 1000, let me know.

only problem is that those heatsinks are live, so this will conduct power to your loop

please don't stick your finger in res to check level while running PSU......instant Afro with burned finger...... results

hmm.. thats not good at all actually.
This may make me rethink my decision to do this.
Maybe I'll just get a 44cfm yate loon and call it a day.

Wow, I love my X3. Mine is whisper quiet, I can't hear it at all. Oddly enough, you're not the only person I've heard with this problem. The first thing I did when I got mine was trip the Green and black wire to fire it up.... I couldn't hear it at all. QC issue I guess, it wouldn't be Ultra's first problem in that department for sure.

[RedRaider]

Eddie....Just step up to the plate and get what I've got on the way...

Silverstone ZM1200M Zeus...... 95A Single-Rail...:omg:

Interesting. I did fire it up outside the case and it was quiet. But once I got it into the case and finished, it got louder. It must be due to the higher load or hot air from all the radiators pushing hot air into the case. I think the PSU fan is thermal controlled and cranked up the RPMs.

That 80mm fan will make crazy noise like the P & PC PSUs.

Is this PSU better than the Ultra X2 1600watt? If I remember correctly, the X2 1600w only pulls 65A?

[RedRaider]

It's a single 80mm SanAce... ZloJack had one, he claimed it's not that bad...

I will have (21) SanAce H1011 fans in my build, along with (8) Yate Loon Mediums. I'm not concerned with a single 80mm fan making noise...:ROTF:

You sure those heatsinks are live ? In principle, it's for dissipating heat from the back of those transistors but current isn't passing thru them.

I have made a water cooled psu, and I will say it is NOT for the novice. Apart from the dangers, it is technically quite a challenge.

You have a steep learning curve between here and where you are capable of building a water cooled psu.


Can you braze or silver solder copper? Capable with hand tools? a Mill and lathe will probably come in handy too. Do you know how a SMPS works?

I don't mean to scare you, I just want you to understand this is a hugely complicated project not for a novice

I would consider a 650watt Seasonic psu instead, the Rolls Royce of power supplies. It IS quiet. I have the 550w s12-550 and at full load its very quiet

Here's pics of mine.

[Xilikon]

That's precisely the idea but I used heatpipes instead. Yours is a good since a well brazed copper pipe should never leak as well. It's granted that with the proper equipment and a good design, it's possible to create a perfect waterblock for this.

[link1896]

You sure those heatsinks are live ? In principle, it's for dissipating heat from the back of those transistors but current isn't passing thru them.

some mosfets have the tab (and or back, depends on package) of the mosfet connected to the drain, and then some SMPS designs have the mosfet electrically connected to the heatsink (no mica washer), hence live heatsinks. Very very dangerous, but it eliminates the thermal resistance of a washer/silicon pad

[Xilikon]

Thanks for clarifying this, you can see that I'm not 100% well versed into electronics design. I'm just asking this since I saw a fair amount of watercooled PSU which tell me it's ok and I now see it depends on the design.

[KaptCrunch]

depends on if any transistors base connection used on sink

or can try DigitalVoltMeter on sink to ground to see if any current flowing

My gosh man, that's beautiful...

Would you kindly post your mod up in watercooling...:innocent:

Agreed. I have the M12-700 and think it is very quiet at full load.

P.S. Awesome job on that watercooled PSU. Wow!

[Baleful]

link, that is a beautiful mod, props man.

[Eddie3dfx]

I am quite impressed.. thats amazing.

can u put this in a build log /D.I.Y style BUT with a warning of the difficulty level Being VERY High !

[Sniper]

WTG Link awesome psu mod! I was like hey my 780W OCZ wasn't loud what's he talkin about! lol. Nice work for sure! Yes make it a DIY for higher level modders deff!

[evilsponge]

I dunno a little nevious about water cooling a PS I had a ocz 700w gamestream a little loud I swaped in a corsair 750w unit with 140mm fan can't hear it at all

Hmm.. I wonder if I could get away with a 140mm yate loon fan in the case.

[Gir]

Yea, I hated my OCZ GameXstreem too... fan was loud as hell and the whole unit died on me after 3 months. Purchased a Corsair 750TX and haven't had a problem since. :2up:
