Hi firstly ill appolagise for my spelling lol its pritty bad, im currently upgrading my system and im wondering weather my power supply will be able to handle it ive googled it and there seems to be differances of opinion,
i will be cf 2 ati4870 on a gigabyte x48-ds5 and my power suply is a OCZ StealthXStream 600w would this be able to handle it for a short time or will it just go bang! (i know it will be cutting it close, i intend on getting a new power supply but not for a couple of weeks).
my system specs are
Q6600 G0 @2.8ghz
4bg crucial ballistix tracer 1066mhz
maxtor sata 500gb
maxtor ide 250gb
gigabyte x48-ds5
ati xfx 4870 1gb
x-fi
lite on dvd rw

your help will be realy apresheated
 
I think it'll run it, you will probably get stuttering in games. id upgrade to a 650/750w corsair or something similer as soon as.

edit: having looked a bit more into it, your PSU has 4x 12v rails with 18amps on each, these cards rec 30amps on the 12v rail. id advise against doing this untill you purchase a new psu.
 
you will be cutting it close, very close, as I don't think the OCZ units are actruly too good I had a 800watt one and it killed something in my PC well sort of killed it, if you had a corsiar differnet story lol

it might take it, but I think you will find having to take out one of them till you get a new powersupply.

So I would work it ouf first using this http://www.antec.outervision.com/ its not 100% right of course but close enough

18amps per each card ;) i had a 512 one with a 18amp powersupply (thernaltake toughpower) it couldn't handle crossfire
