Truepower Trio 550w?  Last response: in Components  Hi all  I
have a bit of a dilemma. My beloved 8800gt has finally ceased to
exist! So I'm looking at purchasing a GTX275 second hand as a
replacement. I've heard that the GTX275 requires a minimum of
550w PSU and 12v 40A whatever that means!! As you can tell, I'm
not very good at all of this technical stuff! My Antec 550w
Truepower Trio psu states that I have 3 12v rails with a maximum
output of 42a (504w. I have 4x 1gb ram, 3 drives, 1 pci
soundcard (high end) and 6 usb devices running from the PSU.
The question is: would my current PSU safely run the GTX 275 for
a while? And what happens if it fails to run the card? I plan to
upgrade the complete system in maybe 18 months but don't have
the cash at the moment - however, I don't want to risk ruining
any of the components.  Thanks in advance for any help.  Your
PSU might handle it; if it does not, you will likely only be
bothered with instantan
