LOL I know right? If the PSU's such a failure then how come it's working well with molex..

same goes for the GPU.. it's working well with molex converters but not PCI connectors xD

Has there ever been a case like this before? LMAO

xD IDK.. sounds a little unethical.. I go to FRYs.. buy it.. use it for testing.. return it to them as an open box and a full refund?

Then again I heard there are times they ask for a 10-15 % restock fee.. I guess I'd rather put that money into a new PSU? IDK

It's so hard to be in a tight budget xD

I am not sure about rails since IDK what exactly they are but that's what I am considering thinking.. sorta..

that the native PCI connectors might have some sort of problem.. since the native 4 pin molexs is just working well..

Then again.. ofc, I am not sure (noob here xD)

hmmm

Hmm.. then what might you think be the problem in my case?

It's so mysterious LOL

It could just be the PCI-E connectors themselves, bad solder job on one or more of those wires, bad connection between the metal connector pin and the wire (or wires), loose pin in the connector housing not making good contact, or any number of other things. No way to know for sure without properly testing it.

Hmm + rep for more stuff to fix the puzzle

What I would also love to know is what does the RED LIGHTS mean on my GPU and why did its FAN RAMP UP to very high (100%) when I use those the PCI connectors..

( and the PC won't start ofc )
(again, using the molex to pci converters solves these)

Might that be the clue to almost tell what the real problem is?

Look in the users guide that came with the vid card to see what the light is for.

Also, go to this guide and verify that all of the wires are in the correct spots in the PCI-E connectors. It's possible that one or more of them is in the wrong spot causing problems.

Something like this can also help you test whether it is just the cable or not, which actually makes sense if it is, as Smurf put it.

I don't have or know of any background or reviews on that thing, but it sounds useful.

+ rep to the latest responses from everyone.

LOL The Ultra 20/24 device sounds cool too bad I don't have an account there xD

@Papasmurf: Uhm. Really sorry but what should I be looking for in those pics?

(if it means anything) the 4870 worked well for more than 2 years by using the PSU's native PCI connectors.. only when I "diagnosed" another PC with it.. then came these problems xD

Should I be looking for dents or what nots?

Also, I'll try looking for the manual tomorrow.. or maybe an online manual..

(hooo wonder what the red lights mean xD)

UPDATE:

Hmm:

Quote:

There are four cressets help users understanding the situation of VGA card,
the farthest from the motherboard is cresset 1; the nearest from the
motherboard is cresset 4, please refer to the attached picture.

http://www.gigabyte.com.tw/FileList/...ga_cresset.jpg

Each cresset represents the following meanings:
Cresset 1--- When the cresset light up, it represents the first 6 PIN additional power
on the VGA card did not install properly.
Cresset 2--- If the GPU is abnormal, the cresset will light up.
Cresset 3--- When the surface temperature of GPU on the VGA card is over
105 celsius, the cresset will light up to warn the user and then shutdown
the computer automatically.
Cresset 4--- When the cresset light up, it represents the second 6 PIN additional power
on the VGA card did not install properly.

i get 1 3+4 atm and me thinks i need a beefy psu replacement.
http://forums.guru3d.com/showthread.php?t=284360

might try and use the PCI connectors again when my 5870 arrives.. OH crap.. that thing has a back panel

Hmm I might as well try the pci caonnectors for my 4870 as well sometime after my card arrives.. 24 hours from now accdg to UPS hmm

Look at the PCI-E connectors to see which colored wires go where. Make sure they are correct. Also make sure that they are all pushed fully into the connector.

WEIRD! Any way to make sense out of what happened? Please?

I would really appreciate it xD
so, you had the 4870 in the old computer and it shut down? and now it wont work in your sig rig? sounds like something happened to the videocard, i still dont blame the PSU.

if you send the PSU in for RMA and they dont find any issues with it, they will just send it back to you and you wasted money on shipping and some RMA services will charge you for their time spend on a unit that had no problems. this is why you thoroughly check for issues before you send in your hardware.

try inspecting the cables or the video card for any burn marks or something. i think something happened to your 4870 that was the fault of the no-name 300w psu in the other computer you were testing.


PS: what do you need a 750w PSU for? lol a good 650w is plenty for your rig.

Yeah! I was really thinking that too xD

But isn't that just plain WEIRD xD

Why would that 300 watt PSU (w/c I also used PCI converters with) "damage" the video card in a way that the video card would "hate" PCI connectors!

It's weird that it went one sided and now only "wants" converters! LMAO

It really doesn't make much sense xD

Wow! Thanks for sharing the "hidden" costs! I'd rather put that money to a new PSU!

Well, I was thinking I'd get an 850 watter.. since I might get another 5870 2gb later down the line

(If I find it for 150 bucks or below! Bought the 5870 2gb E6 for 185 brand new from Newegg [thanks to OCN online deal posts]<3)

ehem..

regarding the GPU/PSU thingy.. doesn't make sense much right? xD
