Hello,
I've an HP mini tower convertible...with a 350 hp Power supply, my motheboard is a Intel Q45/Q43 and my VGA is an ATI HD 4650which means no 6pin i was wondering if i could upgrade that VGA for a 7750hd which is the same power consumption but better and doesnt require 6 pin

Not without a new PSU as they recommend a 400w PSU minimum.

Could you not buy a new PSU and GPU. I wouldn't be comfortable running a system like that.

It will probably work if the old one works but I wouldn't count on it being stable.

Well that 7750 doesnt draw more than 50W from your system.So you would be ok as soon as that PSU delivers that power.

But as u runnign a 27W GPU 13 W more will beok.

I say go with that upgrade.

Well what PSU it is. I need more info not just thermaltalke.

And you would need a new cpu. So total budget for

Ram , CPU ,Mobo is ?

I assume u will use your old HDD .

So u have a Hd 6850 / 500 W Psu / Hdd.

Are there 4 12V rail ?

13/15/16/14 Amps each ?

If so that 7750 will work.

For a system using a single Radeon HD 7750 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 19 Amps or greater.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

So your system have total 320W but it can deliver it all on the 12 V rail. So assume 290/12=24 Amps.

So to end it 50/12=4.1 Amp to run that card.

You are safe :D
