Hi folks, I've treated myself to a Zotac Amp! 1080ti. Trouble is I haven't got the correct cables. I had 1 8 pin and 1 6 pin connected to my GTX970. The new GTX1080ti needs 2 8 pins. Out of my PSU I have 2x6 pins and 1x8 pin. The card came with a 2x6pin to 1x8pin lead (very short) so I can use that. But I haven't got the 2nd 6 pin lead long enough to get to the 2x6pin to 1x8pin lead. So I thought just get a 6pin male to male lead, but the arrangements of shapes is different on each end of my current lead. So only one end fits into the PSU and the other only fits into the gfx card. So I'm finding it hard to know what I need to buy. Are PCIe power cables always not bidirectional? Is that why you have to put it one way round only? Does that mean I can buy any male to male connector or do I have to know what my PSU end connector is? Thanks
Additional query on this... My PSU is probably almost 10 years old. I wonder if I should get a newer one now. I think a Corsair RMx 650W would be enough for it wouldn't it? Just a bit worried a bout my old PSU breaking it or something. But I don't want to spend the £90 if I don't need to. Any suggestions?
Hi there You should be OK with PSU but still 10 years and Thermaltake not sure I would have look on EVGA G2 which are great PSU or Silverstone or Seasonic, BeQuiet But this depends if you want to have modular PSU or non modular If budget doesn't allow then I would get PCI_E to Molex which you can get over Maplin easy for few £££ Hope this helps Thanks, Jura
U can get an evga bronze 750 w, on newegg its often very cheap with rebates, very decent psu, perform as well as most silver psu, good value for the price
Sadly Newegg is not available over in UK and postage from US or Canada will be expensive and on top customs VAT etc and you will overpay these "cheap" deals Hope this helps Thanks, Jura
So you reckon get a new PSU to be safe? I can't find a male to male PCI E lead and this other socket type on the PSU concerns me. I showed it to an engineer here at work and he said it was quite an unusual one. He reckons it'll be very hard to find. And didn't know if it had a special name. Have you guys seen different types of 6 pin PCIe?
Hi there I would get to one be on safe side Can you post pictures of the PSU connectors? PCI_E 6 pin are usually same there, not seen different Hope this helps Thanks, Jura
Incidentally the difference between these two plugs is: Looking at them with the clasp thing on top the black 'standard' one is in the following order left to right, then second row left to right: Arched, Arched, Square Square, Arched, Arched Whereas the red one that only fits into my PSU is: Square, Square, Square, Arched, Arched, Arched If that means anything to anybody Cheers
search in ebay for 6-pin to 8-pin PCI Express Power Converter Cable for GPU Video Card ...any you should be good to go
I have a short 2x6pin to 8pin converter. What I need is a male to male 6 pin to get it there. I tried connecting just one 6pin to it but I got a message saying the GFX card needed the second 6 pin. But like I say I'm hesitant to buy a 6 pin male to male as one end has a different plug to the other and apparently non standard.
so I would use the 1 8 pin just like with your old GTX970 and convert the one 6pin to a 8 pin with a single 6pin to 8pin conversion cable.
Hi there, Is connecting a single 6pin cable to a 2x6pin to 1x8pin lead different to connecting a single 6pin cable to a 1x6pin to 1x8pin lead? Thought it'd give the same wattage.
You can order from here> http://store.thermaltake.com.au/index.php?cPath=18_21 or google..thermaltake modular power supply cables.
Yes, it can be different. The 2x6pin to 1x8pin lead that came with my GTX 1080Ti does not provice all the GND connections on the 8pin if both 6pins are NOT connected! Now I do not know what kind of lead you have. Check if all the 12V and GNDs are provided on the 8pin if only one 6pin is connected. A single 6pin to 8pin converter does provide all the 12V and GND connections properly. see internet for power standard supply connector pinout descriptions. e.g. www moddiy com/pages/Power-Supply-Connectors-%26-Pinouts.html (can't post links as I'm a newbe) 6pin to 8pin converter cables go off from ebay or amazon for just couple of quid. Worth a try in my view. The problem with only one 6pin could be that it provides only 75W. Anyhow, I doubt that it would really be a problem if your PSU is half way decent. You should get 150W from the 8pin, 75W from the 6pin and 75W from the PCI bus itself. In most cases you can draw even more from the 8 & 6 pin connectors. Anyhow, if your old PSU has modular cables, you could get replacement cables as suggested above.
I don't understand why you're having a problem? You say your PSU has 2x 6pin peg connectors and 1x 8 pin peg connectors, so, use that 2x6pin to 8pin adapter that came with your card for your existing 2 6pin connectors and use the 8pin connector from your PSU. Job done If you insist in the mean time that you feel you need to get yourself a new PSU, here's a good one. EVGA 750W GQ CCLONLINE
Thanks guys, I bought a new PSU as I was a bit worried about it being so old anyway. And I can use it in my son's computer that has an even older PSU It is all bit confusing but I did mention I couldn't use the 2x6pin to 1x8pin as it's very short (also female to male) and I only had one long 6pin lead. Thanks very much for all the tips and helpful advice.
Sorry meant to add.... I probably should have tried this. I was put off by the single 6pin lead not working in the 2x6pin to 8pin lead. Thanks
An new PSU was the best course of action imo considering the age of PSU especially when powering valuable hardware. Better safe than sorry. :thumbup:
