Are 661-4665 and 661-4995 PSU's interchangeable?
I have an early 2008 iMac, 3.06 GHz Core 2 Duo (E8435), model A1225 (EMC 2211).
It has 6Gb of ram and a 2TB Western Digital Black hd, along with the Nvidia Geforce 8800GS video card. It has been a great computer.
Over the past 5 years of owning it, the LCD went defective twice, as did the video card, and they were replaced under warranty. But yesterday, the computer made a lovely (and loud) *POP* like a firecracker went off in the system, then died, leaving behind the faint smell of sulfur in the air.
I did my research, popped it open and checked the diagnostic led's, and they were all off, possibly indicating that my 661-4665 PSU was dead.
In trying to find a replacement PSU, I discovered that Apple discontinued the 661-4665 unit (that has 3 heat sinks on it) and replaced it on the next 3.06Ghz iMac with a 661-4995 psu that does not have heat sinks, and is built by Delta instead of the previous LiteOn. The new 661-4995 unit appears to be a little more solidly built, and I was wondering if the 661-4995 will work properly in my system, or should I simply replace it with another 661-4665?
All the connections on them are the same, and the mounting points are identical as near as I can tell.
Just need to know which direction to go!
Thanks very much!
Is this a good question?
