Hi,

I just discussed my graphics card requirement. But closed the thread... just had a small query, I am slightly concerned in the back of my mind somewhere, are there any compatibility issues of 7770 with my PC config ??


i3-3220
Gigabyte H77M D3H
4GB RAM 1333
500GB HDD
PSU - 450W with 2 +12V rails totaling to 39amps
dvd combo drive
Monitor is 18.5 inch with resolution of 1366x768


looking to play BF3, Crysis 3.

Graphics cards are just additional computers who's task is to render pixels.
As long as you have a sufficient PSU, a PCI-E 2.0 (2.1 or 3.0) slot, It will work.
However, A slow processor will bottleneck it.

In your case, It will be 100% fine except for the PSU
450w PSU = You need at least 500w
i3-3220 = good
H77M-D3H = PCI-E 2.0 and 3.0 slots

Bottom line:
Yes, It will work, But, you will need a slightly better PSU

cheers :)

450w should be enough but just enough. Your PSU will be working at 85% plus when gaming which will reduce its life.

AMD card + Intel Processor = 100% OK

All graphics cards work with all processors if the correct socket is available.

Cheers :)

39 amps for the 12V rail is more than enough, I previously had a 7850 running on a 30amp 12V rail which was highly overclocked, and I still had room for more. As long as the PSU is a good brand, you are fine.

That 7770 has a pretty decent cooler, you'll be able to overclock a bit

EDIT: By the way, all 7770's currently are GHZ editions.

According to FLIPKART.com the minimum requirement for HD 7770 is a 450W PSU but If you go to AMD s site they say 500W or greater is a must.

=> I think you should buy the card and try it on your PC
=> If you encounter any problem like bottle necking then place an order for PSU 500W OR above that
=> And don't worry AMD graphic card with INTEL processor works like a dream

I am a regular customer of Flipkart.com . They have the best PC components range and great delivery :bounce:

thanks Headbomb, Sanil, JJ.

Assuming I buy a 7770GHz edition, its power consumption will only be slightly more than a normal 7770 card.

Following are the 2 PSU options i was referring to (both the PSU's have 2 +12V rails)

1) 450W: http://www.flipkart.com/cooler-master-thunder-450w-450-watts-psu/p/itmdbm7fpuzpszvf?pid=PSUDBM7EDGK2XYFZ&ref=e540ee76-ded4-4a80-a016-d0b76f7914e4

2) 500W: http://www.flipkart.com/cooler-master-thunder-500w-500-watts-psu/p/itmdbm7fefnpygyn?pid=PSUDBM7EDH7YSFTZ&ref=e540ee76-ded4-4a80-a016-d0b76f7914e4

just let me know which one should i go with...


(P.S. I am confused on how to buy a PSU - based on watts or amps ?? guess will have to take that up in the other forum.)

thanks. it would be really helpful if you can go through the links i hv shared in previous post of the 2 PSUs. please note that both of them are 2 +12V rails

(i do understand from your reply earlier that total of 39amps will be more than sufficient, but what if its split on two rails)

1. 450W is 18 & 21 amps
2. 500W is 21 & 24 amps

grt help.

i would try to get the sapphire 7770 OC version + the Corsair CX500... in case of any budget issues i might have to settle for Cooler Master thunder 500W :(

i know i keep sayin this but this is definitely the last question ... I see a Gigabyte 7770 OC edition clocked at 1100 MHz is less expensive by around INR 2000 (US$ 40) against the Sapphire 7770 OC edition of 1150 MHz .

Can I go for the Gigabyte edition as the primary difference I see is that it doesn't support 3D display + 50MHz of clock speed ( my monitor is 1366 x 768 .. nowhere close to HD / 3D ; 50 MHz shouldn't make much of a difference at the screen resolution I am going to play at) or else if Sapphire has a better track record i would stick to it (i hear most ppl talking only Sapphire in case of AMD cards and no other manufacturer)

Also, in case I have to stick with Sapphire .. the normal GHz edition is around INR 1000 (US$ 20) cheaper with a clock of 1000MHz - again I will play games at 1366 x 768 so i can do with this instead of an OC version.

What say

Yeah, sure, they are both good cards. You can easily overclock the 7770 with little to no voltage change to 1150. Gigabyte make some pretty good cards.

Go for it if its cheaper. Maybe then you can go for the CX500.
