GTX 660 ''Please power down and connect the pcie power cables for this card''

Etzix · Aug 15, 2014

Hey all! After reading around here for months and other forums and still not finding any solution i decided to ask. My Gigabyte gtx 660 is acting weird. my computer boots up fine and i can surf the web and do other things. But when i start any program that puts load on the graphic card (such as games) the graphic cards fans start going fast and then it just blue screens. after the blue screen it says ''Please power down and connect the pci-e power cables for this graphics card''. Help?

My specs:
Card: Nvidia Geforce gtx 660 by Gigabyte
Motherboard: ASRock 970 Extreme4
PSU: Cooler Master GX Lite 600w
Ram: 8GB
Processor: AMD FX(tm)-8320 Eight-Core Processor
Win 7 64bit

Thanks in advance!

Do you have the connection from your PSU to the GPU connected?

MeteorsRaining · Aug 15, 2014

Your PSU is the bottleneck, its very low grade Tier 4 PSU. Here is the Tier list:

You should never go below tier 3 with mid range PC and tier 2 with high end PC. You should not have gone below Tier 2. Change your PSU ASAP!

EVGA/ Antec/ Super Flower (or Kingwin in USA)/ SeaSonic are the best ones IMO.
Get a good 600W or higher Tier 2 Class A PSU or a Tier 1 if you can afford it.

Yes its a 6pin and its connected. The 6pin splits up into two cables that are both connected to the psu.

That doesn't sound right. Typically the split end goes to the GPU and in your case, you'd leave one of the 6+2pins connectors just hanging there. I didn't think it was possible to connect the cable backwards but it sounds like you have.

No sorry i just worded myself wrong , its connected like you are saying.

That sucks , but rather the psu than the graphics card. Thank you

Sorry for double post but would the ''EVGA Supernova G2 750W, 80+ Gold'' Be a good choice?

Well i got my new psu and it still happens. So thats 100$ down the drain. Any other suggestions? -.-

MeteorsRaining · Aug 27, 2014

Check if all connections are firm, especially power ones. That's really absurd that it still happens. It may have to do about loose MoBo connections.

Etzix · Aug 27, 2014

MeteorsRaining :

Ive reconnected wires alot of times. I cant find any loose ones. Or missing.

MeteorsRaining · Aug 27, 2014

I fear this's the only option:

Sucks. Hopefully i can selleri my last psu back to the one i bought it from for a few bucks. Sorry if my mood is not the best. 100$ you know. But thanks alot for your help. Could you recommend a graphic card in the 300-400 $ range?

MeteorsRaining · Aug 27, 2014

I'm really sorry to hear that too.
I hope you find a good buyer!
EVGA SC ACX GTX 770 will be a good buy

And, R9 290 Tri X is $420 and a lot better card than 770 (10-20 FPS), if you can buy one!

Etzix · Aug 27, 2014

MeteorsRaining :

Sapphire Radeon TRI-X R9 290 4GB "OC" ?

MeteorsRaining · Aug 27, 2014

Yes that one, I know its out of your budget, but that's like the winner b/w GTX 780 and R9 290, let alone competing with 770

Etzix · Aug 29, 2014

MeteorsRaining :

Sorry for asking, but is there anyway it could be the CPU or Motherboard? I always hear a strange crackling sound when i start the computer , and start games. But i cant tell where from its coming. Just dont want to spend 420$ and then it still doesnt work. Thanks in advance.

MeteorsRaining · Aug 29, 2014

I'd actually advice getting it physically checked from an expert, we can advice on each and every possible issue but can't actually take the place of a professional who can have his hands on your build.

MeteorsRaining :

They just told us to clean the card but that doesnt explain or help us. Theres a 45 day money back guarantee, Do you think i should just buy the card and see if it works? I bought a new CPU and Motherboard when i moved everything from one computer to the other and ever since then it hasnt worked. At first it barely worked at all and my computer closed instantly when i started a game. Now its better but still doesnt work on 80% of the games. When i check values nothing goes to 100% usage.

I know you cant tell if or what. But do you think its the graphic card? Or could it be the motherboard/cpu?

MeteorsRaining · Aug 29, 2014

Etzix :

It'd be a gamble to buy GPU and return it if it doesn't work. If you're absolutely sure you can get your money back, then why not try this gamble! If it works=you own a better GPU w/o issues, if it doesn't you know it unrelated to GPU and you return the GPU for your money and we investigate further.

Another thing i might add is i tried another worse card in my computer a long time ago, and it works. Sadly i cant really reach the heavy games with that card and therefor cant test it properly. But it still makes me think its the GPU. im still a bit worried about the whole thing.

The company is a very known one here in sweden and states ''Free Delivery , Free Return , 45 day money back gurantee'' so i think i might order it next week. Thank you for now.

I'll be waiting for your report with the new GPU.
