Paying Back in Savings

This review is from: PC Power & Cooling Silencer MKIII Series 400 Watt 80+ Bronze Semi-Modular Active PFC Industrial Grade ATX PC Power Supply (PPCMK3S400)
Pros:
This power supply is very quiet and efficient for lower power systems, but it holds enough in reserve to run a pretty solid rack of hardware.
Cons:
Can't think of any.
Overall Review:
I chose this PS as a replacement to a 10 year old 350W supply made before 80 Plus ratings and power factor correction were common specifications. Without making any other system changes, I measured performance back to back with the old supply and found that with my system being always on, the cost savings at current rates is about $10/year. So with a sale price and rebate, this power supply actually pays for itself in under 3 years with the money saved.
Older non-PFC supply consumption at idle: 75W with a PFC of just 0.61.
Silencer consumption at idle: 62W @ 0.98 PFC.
The numbers are even better at higher load.
Bottom line: If you don't need more power but your existing supply is not 80 Plus, this PSU will save you money.
It is also best not to buy a PSU that is significantly oversized beyond your needs, as despite the 80 Plus ratings, efficiency actually drops. (Like driving a dump truck around just to move a TV.)
