i need to get one of these cards ,,either 7750 gddr5 or 6670 gddr5.
my psu says like this

+12v1 +12v2
10a 13a


i am currently using HD 4670 ddr3 without any problem and according to my research the power consumption of these cards go as

HD4670 consumes more > HD6670 > HD7750

i.e HD 7750 consumes least power of them all.. and besides none of these cards require a 6 pin connector .. so can i run 7750 or 6670 on my current PSU ??
and will 7750 work on my motherboard ,, as i told i have 4670 plus core 2 duo .... here is the pic of PSU power ratings...

I would run the HD 7750 out of all the video cards listed, it gives of the best performance per watts used. Anyways I would highly urge you to change your power supply, heck I have heard people run the HD 7750 on 350 watt power supplies. Just do yourself a favour and change the power supply to something along the lines of XFX, Antec, Corsair, Seasonic, OCZ etc.

Take a look at this:

Hi

the 7750 is by FAR the winning performer here, by at least double the performance of a 4670. They are not even in the same league anymore, if you can get the 7750 it is the Best of the bunch. It will work on your motherboard and your PSU will handle it fine.

I only want you to change your power supply not to intentionally waste your money but for your safety and to ensure the stability/reliability of your build.

Hi,

It is always a good idea to use a solid PSU as the base for your system, however in this case the OP is replacing his current GPU with one that requires LESS power, so as long as nothing else is changed in the system there will be less strain on that poor little PSU and not more.... hence no kaboom

Yes you do make a valid point but personally (I am paranoid) I find that power supply like a ticking time bomb. You could use that power supply but I would not say it's the best, I hear that unit has poor efficiency and lacks certain protection features (I read another thread about it).

Anyways to the OP if you want to check your PCI Slot version we are going to need to know your motherboard. That being said PCI-E 3.0 cards work fine with PCI-E 2.0 slots.

The Radeon HD 7750 is more powerful and it also uses a little less power, 4w or 5w, than the older HD 6670.
