Hi,

I am very worried i have just broken my HD 4890. I dont know anything about rails, volts or computers. I built up my pc and connected everything correctly (i think).

Firstly, here is my PSU.. http://www.hardware.info/en-UK...t/OCZ_ModXStream_780W/

My specs are

Asus M4A78T-E AMD 790GX , AMD Phenom II X4 955, XFX ATI 4890 1024MB, Crucial Ballistix 6GB DDR3, Zalman CNPS9700cooler, 500GB SATA II, OCZ 780w

My XFX HD 4890 has a 6pin socket and a 8pin socket.... but it only came with a x2 6pin adapter? wheres the logic?
Anyway because it needed a 8pin and a 6 pin i pluged one 6 pin connector into the 6pin slot (directly from my psu) and i then plugged a seperate 8pin connector (direct form psu) into the 8pin slot. so all together i had all plugs fully filled. I turned my pc on and disaster :facepalm:

Smoke came from my card and i could smell the fried GUP... If the realised that i had pud 2 12v (20A) into one card. was that why i fried it?

I have only got the card to day and i have been saving up for a 4890 for ages (i am soo upset)

I need to know...

do i need a new PSU for my system because it is not good enough?
and is there anyway i could get a replacement if i tell the company it was dead on arrival? or is it obvious i fried it?

i am so worried and very worked up... please help me

thank you

I'm not sure I fully understand what happened here. It sounds like your PSU didn't have an 8-pin PCIe power connector.

So what exactly did you plug into the card's 8-pin port? Did you force an EPS12V 8-pin connector into the card instead? That's meant to be plugged into the motherboard.



Edit: Just an FYI, and to pre-empt any shady discussions -- RMA fraud is not to be discussed in this forum.

O noes, you let teh magic smoke out. :(


It's not ethical to RMA the card but you might be able to get away with it.



The only reason I can conceive of the card going up in smoke is if you put the wrong connector into the card - and if it was the wrong one, it wouldn't have fit. You were correct to use the pins directly from your power supply, the adapter is only there for if you don't have dedicated lines from your PSU. It didn't fry because your PSU is insufficient (you'd really only need about 450-500w), it most likely fried because power went where it wasn't suppoed to.

Did the 8-pin you plugged in fit, and go in easily? There's an 8-pin connector for your motherboard too, but it shouldn't have fit. Perhaps you had some (live) bare wires touch the card somewhere and fry it? The card was completely stock?

I just looked at the link he provided. That PSU has no 8-pin PCIe connectors. It has one 8-pin EPS12V. And the card didn't come with an 8-pin adapter.

It's not really clear how he got the EPS12V plug into the card though, if that's what happened. I haven't tried it myself, but I assume they're keyed differently.

The card is brand new...

The 8pin connector, on the PSU it said the wire is called CPU_2/PCIE2 and it has 8holes
was this supposed to go in the motherboard? (there is not slot on my motherboard for this though)

do you want me to take some pics?

If you post some pics of the connector, that would help clear up the question of what got plugged into the card :thumbsup:. (We need a picture of the end of the plug that was connected to the card, not the end that was connected to the modular port on the PSU.)

Newer motherboards use the 8-pin connector instead of the older 4-pin.

Your power supply only comes with a 2 6pin PCI-E plugs and no 8 pin PCI-E plug. What you needed a 6pin to 8pin PCI-E converter plug you can buy at newegg or ebay.

I want to know how did the 8 pin cpu connector fit into the 8pin PCI-E on your 4890? Did you force it in to make it fit or was it a perfect fit?

If smoke came out you definitely fried something. Your power supply and the 4890 potentially be fried. Worse your entire computer could be fried.

Im going with a fried GPU and Mobo, and possibly the PSU as a worst case.

:confused:

Yes, it was.
It's an EPS12V 4+4 connector to be plugged into the motherboard next to the CPU.

http://www.ocztechnologyforum....showthread.php?t=38581

This review shows it the same way...
http://www.virtual-hideout.net...tream_780w/index.shtml

It should also be mention OCZ doesn't even make that PSU anymore...
http://www.ocztechnology.com/p...tream_power_supply-eol

There shouldn't be an 8Pin connector labeled like that either.

Honestly, though. You probably just killed your video card and motherboard. Possibly PSU as well.

For the Modstream

If the connector you put in your card was black, you used the 8-pin EPS connector. It has 4 hot 12v wires on the clip side and 4 grounds opposite. It would basically reverse the voltage to the card and add one 12v in a ground spot.

If the connector was red, you had the right connector. It has two hot 12v wires opposite the clip side and the rest are grounds. On the Modstream one pci-e connector is a 6-8-pin that has two extra ground connectors.

Here are some good images to help you figure out what you did.

From reading Ryder's post in the OCZ forum, it sounds like the reason that particular modular port is labeled "CPU_2/PCIE2" is because there are two cables that can be connected to it. Either the 8-pin EPS12V or a 6-pin PCIe cable.

It should not be interpreted that the cable that connects to it can be used as both a CPU power or a PCIe power cable.

This would be a problem...

The purpose of that particular cable is that it's an all-in-one solution for the two different types of CPU power connectors on a motherboard.

With motherboards that only have a 4-pin connector, you plug in one of the plugs and leave the other unused. With motherboards that have an 8-pin connector, you plug in both.

(Sorry, I gotta run. I'm sure someone else will be along to offer suggestions as far as how to proceed.)

You probably just fried the videocard. But really, afaik the 4 pins shouldn't fit into a pci-e connector. I'm going to have to try this at work tomorrow, but from what I know, the pci-e connectors have triangle and round plugs, and where you plug them in, also are round/triangle. So, it's pretty much inpossible to do it wrong.

Im going to ring the company and say it was dead on arrival... (will they find out?)

what am i supposed to plug into the video card anyway?

also like i said the powersupply still works, the mobo lights up, the heatsink fully spins, the 4890 does look alive (fan spins and the 3 power lights are flashing), the DVD drive works, and i am now going to try to get into bios...

if the mobo is broken would it still be able to power every thing?

is it even possible that even after smoke it still could work (if i get the right connectors)?

The label on the PSU is referring the the modular plug itself, meaning you can plug either the CPU-2 or PCI-E2 into it not where the actual cable should be plugged in.

Good, Good your plugging the CPU-2 cable into the CPU-2 modular plug which is right.

Bad, the EPS12V (4x2) was supposed to be plugged into the motherboard next to the CPU. Depending on which motherboard you have it will either be a 4 Pin or 8 Pin. Which is why it's a 4x2 cable, so it supports each type of motherboards.

That would be a 6+2 pin PCI-E cable, in which all 8 pins should of been plugged into the 8 pin spot on the card. Then used the second 6 pin cable that was also included with this PSU.
Had you done that you wouldn't be having any issues right now, barring nothing was DOA.

Well for sure you video card is fried. As far as what else, you won't know until you replace the video card.

For the 8 pin, you should plug in the "6+2" pin connector on the video card and to the "PCI-e 2" connector on the PSU. And for the 6 pin connector on your card you just plug into the 6 pin connector on your PSU. Man I feel bad for ya if your card is indeed fried. :(
