So I finally got around to building my water cooling pc. All was going well. Finally got to a point to leak test it. I got a dual loop using a koolance res for ddc pumps. Started on my gfx loop all seemed fine pump was humming around pumping that lovely red mayhems fluid. Next I put the CPU loop in, nothing happening :( mmm so I turn off power unplug the gfx loop pump. Put in the CPU one turn power on all of a sudden pop from the psu and some smoke :( naturally I unplugged everything as quick as I could.

So now I don't know what to do scared to plug the psu in again. I don't understand what could have gone wrong. I really hope someone here has an idea any help would be great.

Psu is a ocz 1250w ZX
 
Have you got a PSU tester? Or do you know how to short the PSU to jump start it?
If you do try that and see if it turns on. I doubt the pump has actually caused it to blow, it wont even be pulling anywhere near enough power to blow it unless it had a flaw in it from the start.

Maybe a capacitor has gone inside. Check through the grills to see if you can see any damage.

Is the PSU still in warranty?
 
No I don't have a psu tester sadly. By jump start do you mean like using this ?

I bought the psu from the mm here about 1-2months ago it was running my last rig fine and as mentioned it was running my gfx loop pump fine. It was only when I plugged in the CPU pump on its own that it went pop and smoke came out.

I've had a look through the grill I can't see any obvious damage

Yeah that ATX bridging pin, was that how you were starting the PSU to run the pumps?

If you can get it on again try something small like a fan to see if it works off the PSU.
I don't have any experiences with a PSU popping something and working fine so I wouldn't recommend putting the pump on incase it damages that.

If you have another PSU to use try running the pumps to see if they're fine.

Could it be that there's a little leak that dripped into the PSU? I would try getting the PSU rma'ed if possible and if there is no warranty I would open it (after discharging it) to get a closer inspection on what has caused the smoke. If it's a capacitor I would get a replacement one and solder it on and see if it works.

However if it works with the fan plugged in as above then it'd be hard to know if soldering a blown component inside fixes it fully. If it still works then fixing a blown component will have no testable change.

Personally depending on how much your rig is, I would buy a decent PSU. If you needed a 1250w PSU I'd imagine that it isn't running something cheap and I wouldn't risk it.
 
Yea I was using that bridging pin to run the pumps for the leak test. I will see if I can get it working again tomorrow and do as you suggested try get the psu to run a fan.

I do have a smaller 500watt psu which I know works so might give that a whirl. If I cannot get this ZX to work.

The psu was sitting outside the case well away from any fluids. I kept out for the exact reason you mentioned. I did not want any fluid to drop into the psu in case I did get a leak.

The psu was from new (even though bought from the mm) the reviews I read said that the ocz zx psu's were pretty damm good which was why I got it.

I'm just wondering if there's maybe a problem with the pump though now :(

Bah annoyed and upset now. I'm going to sleep it off and tackle it in the morning.
 
What pump was it? I don't think it'd have damaged it but if it has it's better it damaged that than your system. However if OCZ ZX are decent quality it'll have some form of current protection.

If the PSU was from new, try contacting the seller to see if you can get some proof of purchase and try to see if you can it replaced/repaired under warranty with OCZ (unless it's out of warranty only then would I try opening it myself to see if it can be fixed).
 
I don't think the PSU could be damaged by it unless you got water inside it.

1250 is plenty to run pretty much any rig.

Just ask to RMA from whoever you bought it from?
 
Fingers crossed. You can always buy a replacement PCB (with some soldering to be done) and fix them up, if the pump is dead.

What you haven't mentioned is when the PSU went pop, did you still hear or see the pump running as you went to unplug everything?

If it was then it'll probably still be working.
 
Well psu is deffo dead :( turned power to it using the bridge and the inside glowed up like a Xmas tree and a bit more smoke came out :( sad times.

Going to contact seller and see if can get it rmaed going to grab my old psu though to check if the pump is actually ok though

Edit: last night when it went pop the pump wasn't doing anything it sounded like it was starting up but then it died down and psu poped.

Well at least you know it's the PSU, maybe when it popped it just drained of power instead of frying the pump.

Hopefully you can get an RMA, only problem might be sending the PSU as I think OCZ rma base is in the netherlands.
 
Could it be that there wasn't enough load on the PSU when you tested it? If the pump was faulty for example...might cause it to blow? just a suggestion, I'm baffled.
 
Well there is deffo something majorly wrong with that pump... I just put in an old psu I had tried it on the gfx card pump worked fine. Tried it on the cpu pump and now my psu won't start at all :( so that god damm pump has now broke 2 of my psus ! What the hell ! How could it have caused that.

Mind due this time my old psu just didn't turn on at all and no pop or smoke either. But now even with it unplugged it won't turn on :confused:

Edit: after leaving the old psu off for a few mins it's working again but I dare not put in on that pump again lol

Well I have been the exception it would seem :( and I honestly don't like it.

I took the problematic pump out of the res. I can't see anything obviously wrong with it. Can I power up the pump without water to it just to see if it works ? Or will just cause further problems ?
 
As mentioned though works fine with one pump it's just the second pump that's not doing anything. I'm really at a loss with this really don't know what's gone wrong :(

Now I've taken the second pump out of the res I'm going to quickly turn it on and see what happens. If thats screwed looks like I'm going to be needing a new pump and psu :( or hopefully the psu rmaed

Ninja edit: ok so now I am confused as hell. I plugged in the 2nd pump to my old psu while it was out of the res. so it was just sitting on the table while I waited for something evil to happen. Guess what worked completely fine !! Seriously what the hell !!! Could it be that it wasn't seated properly in the res ? This my first time using a res/pump combo thingy. But I mean it looked like it was in there properly I followed the koolance guide to the tee.

Update ! I got it all working now :D I guess the pump wasn't seated in the res properly. No leaks either :D just going to bleed it out now and have it running for a while.

I guess that the ocz ZX was just faulty :( time to get in contact with the mm guy see if ram is possible. If not sod it I will just buy another psu. So glad to see the pumps running now though. Just a shame about the psu. I really don't know why it blew though that much is still a mystery, it ran my last pc fine for about 3weeks or so and no problems I plug it into these pumps and boom it blows really odd
 
Glad to see it working fine. I knew a DDC couldn't blow a PSU.

As for running it without water, it always says never to do that. If you want to test it to see if it spins just have some water in a loop on itself at least then test it.

Good luck with the rma if you get it :)
