Just to remember, we are assuming that this is a 610 W power supply and we tested it as such.
The main problem with this power supply is that it can’t work continuously at a room temperature of 45º C. During our test number three the power supply shut down after 3 minutes, during test number four the power supply shut down after 10 seconds and during test number five the power supply shut down after 5 seconds. Well, at least it’s over power protection (OPP) was clearly in action.
iPower 660 is a textbook example of a power supply which was labeled at 25º C, which is a temperature impossible to be achieved inside a computer.
We have also seen that the rectifiers used on this power supply didn't provide enough current for this unit to be able to deliver the unit's labeled power, and our theoretical calculations proved to true.
We let our load tester and power supply cool down and turned them back on with pattern number four. The power supply could only stay on for two minutes – it shut down when the room temperature achieved 40º C.
So even though its power supply can in theory deliver up to 610 W, in practical terms this doesn’t happen. This unit can’t continuously deliver more than 350 W at a room temperature of 45º C. |
