What GPU for the G20AJ ?

[Zimi1975]

Hi Guys

I want to buy a new GPU for my G20AJ. Can I install every GPU or is there something I need to be aware of?

Thanks

Things you need to know:
1. Did you G20 come with one or two power supplies
2. If you have a G20 with 2 power supplies then the 230w feeds the GPU, any GPU you choose should not exceed this wattage. Cards that you can use are GTX 970 and GTX 980 are good choces
3. You want to buy a reference card with a centrifugal fan, you cannot use a card with the added fans

hi, thanks

1. i got with my G20 two power supplies. I currently have a GTX 760 2 GB. But I want to have a better card. Also its seems the cards makes me a lot of problems.

the 970 GTX is a option, yes.

thanks

a reference size GTX 970 or 980 should be fine. i took a gamble with the 980ti but i had to put a 90% power limit onto the card with MSI afterburner. if you don't want that hassle then pick the first two cards. make sure it fits the reference spec size, nothing bigger (not longer, not taller) it won't fit if it's bigger than the original nvidia cards.

Also the 760 has the bracket at a shorter point when installing a 970 or 980 you need to move that L shape black frame with 2 screws holding the card in place (you have to take it off anyway to remove the 760)

Someone private messaged me but was using a guest account (forgot to sign in?) about what reference meant. Reference means the stock design by nvidia. so the link below shows "stock" or "reference" design specs.

a card with the same dimensions should fit fine too. (as long as it's not longer and/or taller)

So only cards that fit within the reference size of 10.5" L x 4.376" H will work. also the PSU draw does work initially so you can get into windows, but i found the card acted funny in the 3D Mark Fireworks test (crashed) and some apps didn't launch properly, until i installed MSi Afterburner and put the 90% power limit on (it doesn't reach it often, so everything is controlled) I saved the profile and keep it active at all times.

It's been stable and acting normal ever since.

Both PSUs required btw (180w & 230w)…*if you don't want to use the MSI program grab the DELL Y90RR 330W and replace the 230W (one person tested it on a 970 system, i haven't tried it out yet. i may end up doing it later and testing. (no rush on my end) still running the 230 & 180

Heya Guys,
I have the Asus G20AJ with the Gtx 970 4GB. In game mode my Gpu reach fast 80 C and keep on them, but the fan speed is always at 50%. it's safe for gpu have this C and it's normal? What's your Temp?
Thx!
