Problems With LEPA1600 Gold, keep shutting down.

[radeson]

Hello,

I am having issues with a unit I bought on EBAY a few months ago. (I know, bad idea right?) The unit is a LEPA 1600w G-series rated to 1700 watts. When I am in the middle of some high demanding game sessions (usually long before the issue happens, but not always) it likes to just kill on me. It shuts completely down, and all that is left on is my MOBO LED lights. I have to unplug it and plug it back in for it to turn back on. I push the 'ON' button and reset and nothing...
It was supposedly brand new, never used, open box on ebay. The guy had no bad reviews out of 500 or so. So I pulled the trigger. Everything looked new, but it could easily have been used. I want to get a new psu, but I want to make sure it is a PSU problem first. Any advice??? If I do go for one do you think an EVGA 1300 supernova G2 will be enough?? (BTW I like overkill)

I am running: AMD FX 9590 BLACK EDITION, ASUS CROSSHAIR V FORMULA Z MOTHERBOARD, 4X SAMSUNG 850 PRO 256GB(3 IN RAID AND 1 IN RAPID MODE FOR OS),SEAGATE 1TB 7200 RPM, DVD_RW DRIVE, 32GB GSKILL TRIDENT X 2400MHZ, 3X RADEON R9 290, LEPA 1600w FULLY MODULAR PSU(RATED TO 1700w) KOOLANCE CUSTOM WATER COOLING LOOP I think thats it.

OH, btw i just got a "KILL_A_WATT" meter, and I turned on Tomb Raider(newest) with everything all the way up. It didnt go over like 1025 watts. I believe my processor is 220 watts fyi. I also read that the radeons can take up to 350 watts a piece under full load, so isn't this way under what it should be??? I also made sure all the plugs were firmly in place multiple times. I even took them all out and re-ran all the cables once.

Please Help

Yeah, especially considering you have lots of expensive hardware that deserve a brand new unit that's under warranty.

The unit is a LEPA 1600w G-series rated to 1700 watts.

In what way is a 1600W PSU rated to 1700W? 1600W is 1600W, isn't that common sense?

If I do go for one do you think an EVGA 1300 supernova G2 will be enough?? (BTW I like overkill)

With your hardware, 1300W is pushing it. You're looking at around 1100W theoretical maximum load in a game that's both CPU and GPU heavy, and that's not counting voltage spikes. Tomb Raider is mostly stressing the GPUs and may not be the most optimal game for pulling max watts from the second and third card, so it's not necessarily indicating max load. I would want to have an EVGA G2 or P2 1600W.

By the way I'm really surprised to see an AMD CPU in there. Even an FX-9590 is just plain inadequate for triple crossfire, you need an overclocked Intel CPU to get the most out of those cards.

 

[radeson]

To be honest, I regret getting AMD everyday. I have had SOOOO many problems with this rig ever since I built it 3-4 months ago. I haven't built a computer in like 6 years and i wasn't keeping up with all the tech news. So when I seen an AMD processor @ 4.7ghz for 230 bucks I just figured 8 cores at 4.7 has gotta be fast.

So i jumped the gun and wasted all this money on a rig I'm not truly happy with. Sucks to be me right now. lol. Anyways I am about to get my taxes back and i really want to get
a new Intel processor (def. the 5960x) and the ASUS x-99E WS mobo

http://www.newegg.com/Product/Produc...-263-_-Product

I can pry afford to processor and mobo with a few sticks of RAM to start. And use the parts I have now to transfer over to it. (Just until I can upgrade to Nvidia) I am sick of all these problems I am having. Not just with the PSU, thats not even related to all the other crap I have to deal with with this setup.. I could rip my hair out.

BTW lehtv on the LEPA 1600G box it says "1700 watts peak power"... that's what I meant.

Why the 5960x? Do you realize how bad performance per cost it is? Even a stock 4790K that's 1/3 the price will perform 30%-50% better than your FX-9590. In addition, 4790K is actually going to be just as fast as 5960x in almost every game because you need a very well multithreaded title for the 5690x to shine. 4790K actually clocks around 300 MHz higher when overclocked.

You can also reuse your RAM sticks. All you need is a new CPU and mobo if you want more speed.

Oh, peak power, ok. That makes sense. Typically high end units these days rate their label wattage based on continuous wattage, but with only 100W to spare until peak wattage, I would say the continuous long term max wattage of the LEPA is somewhere around 1400W rather than 1600W.

I def cant put ddr3 ram in ddr4 slots though right???? Dumb question probably.

Lehtv means you can use your current ram with the 4790k and a Z97 mobo. Unless you are doing encoding or similar tasks that can use that many cores you'll have better value to go with the 4790k for gaming. Wait for ddr4 to come down in price as it slowly gets adopted.

 

[radeson]

well, im intrigued. I am curious as to what kind of mobo i should get. I want 4 way SLI/CFX. Best i can get right now for that CPU preferably. I haven't seen anything thats jumping out at me. I would prefer ASUS, maybe the MAXIMUS VI???

+1
Id save the money and buy twice the ram(assuming yours works with it), im not sure about the Leepa 1600 W. It maybe way over ratted, and just not able to give you what you need. I have a G3 1300W EVGA great PSU!!!
But lets find out what exactly is happening with your set up, tell us what your doing when it happens are you over clocked if so what cooling are you using, ETC ETC ETC?
And what exactly happens when it dies out on you, have you checked the error code? Have you tried running with less memory sticks, less video cards, bare minimum?

Oh and how long have you had the PSU, is it covered by the seller still?

 

[radeson]

So far it only happens when im gaming with 2 or three cards, I am running at stock speeds and nothing oc'd bc it really doesnt need it. when it happens it just dies. Nothing on the mobo but the leds on the "start" button and that it, no error codes. Just instantly off. My temps are all at 60c or under at all times.I have a water cooling loop through my GPU's and CPU from koolance.

You know, this is gonna sound like i am a noob, but i assure you when i installed everything i tried to space things out so i wouldnt overload any particular 12v rail. well, i was reading on LEPA's website that it uses multiple 12v rails, and if you put too much on one it could overload the overvoltage protection. So i got to thinking and when i installed this unit I couldn't fit the 8-pin cpu power cable to the top of the motherboard when i put it together. So I used the 8pin connector that splits off of the 4-pin Motherboard cable (they are both motherboard cables that are really long for cable management. I think that my cpu is drawing too much power from that rail or somthing. It was just a hunch. so i pulled out an 8-pin molex extender and extended the proper cable for the job. Well, I've been cranking it up all night and it still hasnt shut down on me yet...

Could it be something as simple as this??

A multi-rail PSU can definitely shut down when powering a 220W TDP processor from the wrong rail. From the looks of it, each rail can only handle 20A which equals 20A * 12V = 240 watts. I hope it doesn't shut down on you any longer . Upgrading to Intel would make it even safer to run without fear of shutdown since you'd be using about 100W less from that rail.

I'm not particularly familiar with 4-way compatible Z97 boards, all I know is they exist. Browsing what's available, Gigabyte Z97X-Gaming GT and Z97X-Gaming G1 seem to be pretty nice. They're both much cheaper than Asus Z97-WS and Z97 XPower, with the GT being available for $189 with rebate. Both are compatible with PCIe 3.0 x8/x8/x8/x8. The GT and G1 have almost entirely identical specs, the G1 just has dual NICs and a Creative sound chip. I'd probably go with the cheaper GT, the only bad reviews on newegg are from users who received DOA or otherwise malfunctioning boards.

I was thinking of going with the Asus maximum vi extreme. Any reason why I shouldn't? Price really isn't a factor.. I want as many bells and whistles as I can get. Plus I like the external OC controller.

VI Extreme is a Z87 board, didn't even think of looking at Z87 boards. The newegg page does say it's compatible with 4790K (not all Z87 boards are), so you've got that covered. The only question remains is whether it's worth $100+ more than the Gigabyte GT board. What you get:

- mPCIe WLAN card
- Intel NIC instead of Qualcomm Killer, so no need for heavy driver software
- onboard thermal measurement connectors (probably not going to need)
- OC panel

On the other hand, Gigabyte has a bit better audio hardware, although the audio chip itself is the same ALC1150.

For me, the Asus board doesn't offer enough to be worth all that extra. If you don't care much about the cost and like the extra features and/or want Asus due to familiarity, go ahead

Yes, it can be that simple.
I've used Lepa G1600s in many installs that were capable of tri or quad video cards.

The MB/CPU connectors should be used only for that, as those rails are designed for that load.
You should have no problems with that as the MB/CPU connectors consist of 2 x 20a rails.

The 4 red connectors are for your video cards, each card should be on a separate rail.
Each of those can supply 30amps.
Since you have 3 vid cards, I would use either rail 4 or 6 for your SATA/Molex loads and use rails 3, 5, and whichever of 4 or 6 not used for SATA/Molex, for your vid cards

The G1600 can/does produce 1600w continuous easily as verified by the tests on jonnyguru's site and several other sites.
The 1700w limitation for peak is dictated by need to limit the draw from the wall outlet in the US.
Breakers are only designed to pass 80% loads continuously, so 16A continuous on a 20A circuit.
The G1600 could probably peak at slightly over 2000w on a 30a circuit that's not practical for either the US or EU, hence the 1700w peak design limit.

The 16A max draw of the PS is also the reason for the different power cord as required by IEEE. Dell also does this on it's 1000w units, as should all OEMs, as std. cords are not rated for that high an amperage by IEEE.
You'll find that some OEMs don't adhere to IEEE standards though and continue to use the wrong cords on their PS.

BTW - you can trip a 15A outlet's breaker if you try to max this PS for more than a short length of time. (as with any PS that can draw more that 12A on a continuous basis in the US)

Yeah lol I know. I had to literally upgrade my panel to a 20 amp breaker because when I was gaming I would constantly pop the breaker.

 

[Micrornd]

Please tell me you are kidding?
NEVER just put in a bigger breaker, you are creating a fire hazard.
The wiring needs to be upgraded to 12ga. (14ga. is the norm for 15A circuits)
PLEASE for your own safety address this issue properly and put the coorect size breaker back in your panel and add a 20A circuit correctly.

 

[radeson]

Lol. I used to do some light electrical work and I made sure it's running 12g before I did that. But thanks for the heads up.

this is exactly your problem.

you should consider the evga 1600 g2 or p2
