Graphics card with limited PSU-power

Hi!

I have a Fujitsu computer with a Ivy Bridge i7 3770 and 16gb RAM, so naturally I would want to play games with good graphics-settings, but the thing is the PSU is just 280w, and apparently Fujitsu use some kind of proprietary motherboard power-connector, so I can't upgrade it.

Right now I have a HIS Radeon HD 6670 and it works fine with 280w, but I would like to get a better card. I know most cards say you need 500w, but my 6670 says that as well, and it works great.

Are there any better cards that will work also, or any other way of fixing the issue?

Thanks!

You could get an 800MHz version of the HD7750, which needs no power connector (the 900MHZ versions do). This card will actually use less power than your HD6670, but will significantly outperform it.

a 7750 or a GT 640 run off of PCI Express power and are both PCI Express 3.0 which is boosted by your ivy bridge cpu. Now I got a question for you... Could you take a picture of the "Proprietary" motherboardboard power connector? so We know what your talking about because I've been in this industry for years and never heard of a single company changing the type of power connectors used on the motherboard

Of course it is an Ivy Bridge, got that wrong in the first post!
Here is the connector:

That is the only thing coming out of the PSU, there is another connector from the motherboard to HDD's/DVD etc.

Ok so answer this.. if you were to unplug the power cable from the thing on the motherboard would you have this:

I mean even still if not but it looks similar then I think its some wierd extended 8 pin. and you should be able to switch out your power supply. I mean i know they are a wierd off brand motherboard manufacture but most everyone sticks to industry standards. could you post a picture of the connector from the motherboard to the HDD's. Because they should either be SATA or for some reason using old IDE which still isn't un common on a Z77 board

The other connector is a standard SATA, http://i.imgur.com/ELoxE.jpg

Also the main power connector says PWR12V next to it on the motherboard.

Well first off, the PWR12v means its coming off the 12 volt rail. Second the manufacture that made you computer must have been on crack when they designed it. Your "SATA" power connector is actually classified as a 8 Pin motherboard power connector. but in the picture i noticed the actual hard drive was running off so I'm guessing the power supply has a cable like so:

If you were to get a new power supply, you might would need some power adapters for it to work but its possible to do so
