Lepa G 1600 Shutting down by itself (Dying)

[KaRLiToS]

Hi guys,

I have a dying PSU in my hand and I wanted to share my experience. In 2012 I built my Quad Damage rig version 1.0 and decided to choose the Lepa G 1600 for my Quad HD 7970 with 3930k. I bought a unit from the reviewer Oklahoma Wolf ( a reviewer from Jonny Guru ) on OCN market place back in the day.

The unit had some BAD whinning during load and Lepatek decided to honor the Warranty even though it wasn't under warranty anymore because it had been tested and reviewed.

Incredible service by the way, prompt and friendly. Ecomaster and Lepatek are great companies.

BUT the last few weeks were a pain with my rig. PC Shutting down during gaming after long periods (2 hours) and then this week I started to play Metal Gear Solid Phantom Pain and I couldn't do more than 30 minutes inside a game. Just to inform you that the rig has now a 4930k and 4 x R9 290x. (Quad Damage version 2.90x)

So the troubleshooting started, I decided to go to Windows 10 (from 8.1) same issue. Reverted to 8.1, tried older drivers (GPU) , newer ones. Put my entire rig back to stock. Even on stock CPU and GPUs the rig was immediately shutting down during 3dMark.

Things I tested

• Test each cards one by one on the PSU = Success
• Test 4 cards (each combinations) = FAIL
• Test 3 cards (each combinations) = FAIL
• Test 2 cards (each combinations) = FAIL
• Test 4 cards downclock to 600/800Mhz (instead of 1000/1250) = Success (as soon as I cranck to 800/1000Mhz PC shutting down)
• Run 4 cards from another PSU (EVGA SuperNova G2 1000) = success
• Test each cards at 1200/1425mhz from other PSU to confirm that it's not a bad GPU issue. = Success

I tried everything. When I troubleshoot I eliminate every possibilities. I monitored the Watts pulled from the wall and it looks like each rails are fine but the total watts of the PSU cannot go above 800/900 watts anymore. It's like if my 1600watts PSU is now a 850watts PSU.

I wrote an e-mail to LepaTek yesterday and no news yet. The sad thing is that I sleeved all the cables and it took me 35 hours and I will have to do it with another PSU. No way I'm buying another multi-rail PSU for a system like mine. Single Rail FTW (133amp).

Testing the rig.

My rig is on a dedicated 20 Amp breaker and it shares the breaker with the monitors and speakers, that is all.

I pulled the trigger and bouth a EVGA SuperNOVA T2 1600w (Oh yeah Titanium) .

Oklahoma Wolf did a review on it on Jonny Guru.

Yeah I had a bolt fall out of my old HCP1200 which was a very well reviewed unit as well. Antec wanted to give me a new HCP1000 as a replacement but I had a good moan over at johnnyguru forums and they gave me an HCP1300

Sucks when well reviewed things fail when they really shouldn't but it happens sometimes, nothing is perfect. Hopefully Lepa get back to you with something.

I'm not mad, I'm happy to be getting an EVGA SuperNOVA 1600 T2. I just hope it delivers.

For me, it's better to have a single rail unit. :thumbsup:

I used Lutro's guide here for the pinout. http://www.overclock.net/t/1420796/repository-of-power-supply-pin-outs/0_30 There is an EVGA spoiler.

I also used Molex Diagram and Sata Diagram with my multimeter (ohm tester) to confirm the good position. (I'm a high voltage technician so position matters a lot)

So took me around 3 hours to remove and replace the new PSU, and this including the connector housing inter-change. I have sore fingers from removing the connectors but all is done now. Redid a total of 5 peripherals connectors so they could fit the EVGA ( I ordered some paracord to sleeve the new extensions later this year).

So verdict: SUCCESS Tested 3dmark and no shutdown, I'm very happy everything worked on the first shot.

I know it's much messier than before but I will make a PSU cover and sleeve with paracord, I might also eliminate the bottom radiator.

Thank you all for your help.

You don't see it much but it was a pain to manage the wires. The EVGA is 20mm longer than the Lepa so it was really tight down there. That's why I might remove the bottom radiator.

Sorry for the ugly phone pics.

Quick and dirty PSU cover. Not my taste, will re-work it tomorrow.

 

[KaRLiToS]

Since the last PSU cover was far from my taste, I decided to create a more discrete one where it only hides the PSU label. (Sorry for crappy cell pics again)

Might be the final version of this cover.

With some lights (don't know why I chose blue)

With panel close. (Sorry for reflection)

jesus what a beast of a rig.

have you considered taking your PSu in for repairs? not necessarily by EVGA, but by any electrician.

shame to waste that thing. maybe it's a single busted capacitor.

 

[KaRLiToS]

The EVGA is the new one and is working flawlessly.

The Lepa is my old defective one and was sent for RMA. I'm waiting for it to get back. So I might sell it or keep it, will see what I'll do.

Thanks for the compliment DigDog

Holy crap what a beautiful machine.

 

[KaRLiToS]

Received the new PSU, it looks new just like the cables are in a sealed bag, should I sell it as new ?

I wouldn't, but it's up to you obviously. You can always say it appears to be a new PSU you got as an RMA replacement.
