Im looking on upgrading my graphics card and I was wondering if anyone knew what power supply I needed to use this one, I currently have a small power supply (250W) so im assuming I will have to upgrade that aswell, so if you knew a good power supply to buy that would also be helpful(looking on spending as little money to use the 7750) Any help would be greatly appreciated.

Lol, yeah, you'll certainly need to upgrade. The graphics card alone would eat up about half your power.

What kind of budget are you thinking? I would recommend 550W minimum, 600W preferred, or 750W if you plan on upgrading or want a lot of headroom. You'll want to get a good brand, too. The PSU is basically the most important component if you want a stable system.

Personally, I use the older PC Power and Cooling Silencer 750W. Excellent quality and overhead (Tested at 900W). I'm only using about 300W of it, but I like having the headroom.

Thanks for the reply, I think I will go with the 650W corsair that you reccomended.

@ op get corsair cxv2 430w as it is enough and this psu can handle upto hd 7850 easily.

If your present psu is merely 250 watts, then for sure its going to make your system unstable and prone to hazards(burning of capacitors on your mobo) if you get a 7750 running on it...
I am kinda 90% sure that your psu is of local quality and cheap build...
So even if the 7750 consumes a mere 43 watts, a local psu with a low ampere rating on the 12 v rail can bust your gpu...(you dont want that ...do you??)

so i'd say that the best option for you is to get a branded (corsair,antec,etc) 400w PSU with more than 20 amps on the +12 v rail....
If you are going to upgrade your gpu again any time soon, get a 650+ psu...
But for a 7750 it would be nothing but a huuuuuuuge overkill..!!!
Best of luck..

I Run HD7750 on a 250w power supply.

The res of the system is i3 with 4 gigs of ram and old 160gig hard drive.

Though it is a 12volts only power supply with a specific mainboard, which then transforms curent to 5v where needed. HDD feedds from the mainboard, not the psu.
