Best graphics card that doesn't require a power connector.

[pebbleberries]

I was wondering if there is a graphics card that has crossfire or sli and doesn't require a power connector.

what?

There are no graphics cards with dual-GPU's that are low enough power (i.e. 75W approx) to warrant no additional power connector.

You need to restate the question.

What is your CPU, motherboard and power supply?
Budget?
Purpose of the build?

You can buy ADAPTERS for power supplies if you have sufficient power but not the proper 6 or 8-pin PCIe connector. Or buy a new power supply with the proper connections if the budget is sufficient.

*Your question is ODD because multi-GPU cards are expensive, so asking about pairing with a PSU with insufficient connections doesn't make sense. You must be CONFUSED about something.

If buying two smaller cards then the motherboard must support SLI (NVidia) or Crossfire (AMD), and the card must also be compatible (not all are). Crossfire can work through the motherboard though you'd have to check for which ones work with no bridge.

However, I almost never recommend multi-GPU unless the best or near-best GPU is insufficient. Not all games support multi-GPU and of those that do some have issues. So get the BEST, single-GPU you can afford.

So...

If you want this for gaming, AND have something like a 300W PSU you may need something like a GTX750Ti, but your question can't be properly answered without more information.

Simply you wont find a graphics card that has a low power consumption, or that is Sli or crossfire capable.

Both Nvidia, and Ati do not make graphics cards that are Sli capable or crossfire capable.
Bellow a set price range and tier level fo the card models they produce Pebbleberries.

You would be looking at a mid range graphics card for gaming with a Nvidia, or Ati based Gpu on them at around the £140 price range for each card.

Requiring at least to be safe a power supply that is rated for Sli or cross fired cards in a system starting at about 650w of power.

The nature of the Gpu`s used on each card and the amount of shade processor counts determines i most cases how much each of the cards Gpu`s require in power consumption.

Cheaper cards that are not Sli or Crossfire capable require less power consumption due to les shade processors used with the lower end model range`s of cards on the market you can buy.

I mean, I am looking for a graphics card that has support for sli or crossfire but doesn't have a 6 pin or 8 pin connector.

I'm upgrading from a Radeon 1900x and the power supply only has a 6 pin connector and I'm trying to get best performance I can.

The power supply is not upgradable

At least for Nvidia there hasn't been anything since the GTX600 series that might fit that description. Shaun O and Photonboy are dead on about the low tier cards not getting that kind of support anymore.

Why the restriction of no power connector?

Just about any PSU can support even a 1050 and that will surpass most older x50's in SLI anyway.

Here's an MSI GTX 950 that doesn't need a power connector and is SLI ready:

Its about the only one I've found.

GTX 70 ti is very power efficient GPU, although not SLI....
Well by using a programs called DifferentSLIAuto you can sli any no sli able cards including the GTX 750 ti.

A google search of it will bring up some benchmarks of it.
BEST OF LUCK

I'm basically trying to get the best performance I can get but the power supply only has a 6 pin power connector and is not upgradable so I'm stuck with a gtx 960 or as Jeffrido mentioned, the 2 gtx 950's would be better.

 

[WTKnight]

You can use a dual PSU option... Although not very good, but as you are limited just because of power.... So it can remove your limitations...

yeah, I might actually go with the Gigabyte mini GTX 1060.

lots of power but doesn't require much power.

I'd say the 1060 sounds like a great idea but you really should also consider a need to replace the psu.

How old is it?

Some will last 5-8 years while others ~10 years. In either case, PSU's don't always give a warning when old age is catching up and they're about to go(especially if they're of good quality and have been well kept). I had one back in my P4 days that made it close to 10 then one day simply gave after my latest GPU upgrade(ATI HD series AGP w/ XP DX10 support).

It'd be a shame if your decision is being made upon a factor that won't exist for much longer.

My psu is just over 10 years old but it has a 6 pin and enough watts to run gigabytes mini gtx 1060

I had a feeling after I did a quick check on that 1900x you mentioned. The good news is that there are seriously a lot of good quality, affordable models out there now and Tom's has a lot of reviews on them. Wishing you the best on getting the most of your build(s).
