Aspire Chameleon 550w PSU
Testing
Published: 22nd April 2006 | Source: Aspire | Price: |
In order for our tests on high end PSU's to remain fair and comparable with past and future reviews we have created our own PSU stress testing device. The device is capable of placing a 8,16,24 and 32 amp load on the power supply on single or multiple 12v rails.
The images below were taken during the testing of the 12v rails.
According to the specification given by Aspire, the power supply is capable of delivering 36 amps over both rails. However, when pushing the power supply to 32a load the unit started emitting a high pitched buzzing noise and as you can see from the picture above, the voltage dropped drastically.
ATX specification states that all voltages should be within +/- 5% to prevent damage to components. We see here that the Aspire falls short of this specification on the +12v rail with a -6.3% deviation. The 3.3v and 5v rails however were rock solid never dipping below their specified voltages.

Nice review man. Shame bout it, though as you said, should make a decent alternative to generics for lower level rigs.
I've had one before, the 20p version. I bought it back when I had my P4/6800 rig, to replace my Enermax 350w. I didn't replace it cause I needed to but because I was going to upgrade to s754 soon and I wasn't sure. So I got it, popped it in, and ran 3D01. It emitted a LOUD high pitched squeal but was stable. So, I RMA'ed it and got another one. Same thing! So I RMA'ed that and demanded it be replaced with the Enermax Noisetaker 420w that I had for so long.
Yeh, they aren't that good
. Nice review, XMS 
. Very thorough.
