So guys, this is my first post, first of all my English sucks a bit so...sorry for that

As you can see the title says it all, i want to upgrade from my hd3870 to a hd4890, but im not quite sure my psu can handle it, and this is a big issue for me since they dont sell quality psus in my country(dominican republic), the closest thing they had a while ago is the one i have right now, thats why i got it. I used the power supply calc. on antecs webpage(http://www.antec.outervision.com/) but im not sure if i can trust that.

I think my psu is pretty good so far, but i think the change can be huge from board to board,
ill leave my the specs. here ad thx a lot

what else are you running along with the potential 4890??? (and your english is quite good)

wow, the for the fast reply (and thx ) right now i got:

Stock E8400
2x 1GB Wintec AmpX DDR2 800Mhz
2 crappy generic small fans 1 of the connected to the MB
1x 160 GB old maxtor 7200rpm sata HD
LightScribe dvd/dvdrw combo sata

and thats about it without counting on the current card ofc.

I think you oughta be just fine

this system



ran this

and keep in mind that those 370W may have been measured before the PSU, and they may have been measured post PSU (which means the system really isn't pulling 370W, that's just after the ~20% efficiency loss)

so, i just got one last question, lets say i buy the card and the PSU doesnt cut it, what can go wrong?

the PSU will slowly die lol, in which case you get the better PSU, problem solved??

they put it best

oic, i thought it could take part of my things with it if it broke down, but if that isnt the case then ill just got ahead and try it out, thx a lot man u've been tons of help.

Ya, tell me how everything goes. And if you'll need me to send you a nice PSU if the unfortunate happens

ahahaha will do will do thx man

just to close this thread, i didnt go for the HD4890 i went for the Xfx hd4870 1GB and ended up buying this psu wich works GREAT, really quite and big fan too, its not a cool looking as my old thermaltake purepower but oh well...it does the job and it does it good.

Congrats. Glad that you're happy with your new hardware.

thx man

congratulations , send us some results and pics , scores
