Low end gpu sli / crossfire

[Sk8erpep]

Is there any way to use an AMD radeon hd 7450 in crossfire, there's no crossfire connector and I really need more performance without high power consumption as my power supply is only 240watts so i can't even run a gtx 750.

My computer is an hp elite 8300 sff with a core i5 3470 8gbs ram and a 500gb seagate barracuda.

Any help would be greatly appreciated.

It's non standard power supply due to being prebuilt hp I'm not really comfortable re-wiring like luke did in scrapyard wars 4 so im stuck to a 40w limit on a graphis card with a $200 budget and it must be low profile, thats where im at right now.

I ran 5450's in sli for fun. Got about 50% faster.

But going from 17 to 25 fps in tombraider at 720p min ins't much better.

which gpu manufacturer did you get the 5450s from? asus, sapphire ect.

Rather put some effort into actual upgrading than finding a last resort. You will waste your time and money if you're going to make a crossfire config. Not worth it in the end.

would a geforce gt 730 2gb ddr3 silent be fine? that's bacicly the maximum i can do on this psu
