I have a G5 1.8 single (4 ram slots) and the power supply is/might be going out and I found a good deal on a 600w power supply (Apple Service Part Num: 661-2904, OEM AcBel API-2PC54) the one in the G5 currently is the 450w AcBel can I do this without issues? Thank you, Jeff

As far as I know, the original spec for your machine had a 450w, but I don't think there should be any issues if you put in a 600w as long as it fits.

The 600 Watt is a drop-in replacement.
2003 SP 1.6, SP 1.8
Early 2005 DP 2.0
all other G5 thru early 2005
680 Watt ( late 2005 only )
Late 2005 DC 2.0, DC 2.3
1000 Watt ( Late 2005 only )
Late 2005 QC 2.5

When I had my G5 I remember reading that the single processor machines used a 450W PSU while the dual processor ones required the bigger 600W PSU.
I have read that my Mac Pro uses a 1KW PSU :eek:
