this 750watt enough

post #1 of 8
Thread Starter 
i was just wondering i bought this 3 years ago and i know its a crap and dodgy PSU(Shaw viper 750watt) but just in case
can this be enough to run 2 5770 since my 2nd 5770 is just collecting dust and doing nothing.
note: it has only 2x4 pins 1x6pin and 5xsata 15 pin and can only power up the 2nd 5770 via 2x4pin to 6pin or 2xsata to 6pin
specs
12V1=24a
12v2=22a
3.3v=20a
5v=24a
5vsb=2.5a

Shaw are known to consistently lie about their PSU ratings. Trash it.

Think of the Antec as a good future investment. I loved my 500W EarthWatts, never let me down. Its a lot of money now, but unless you do crazy upgrades you won't have to change your PSU for several years to come.
