I have 2 PS3's. One has been plugged into a surge protector since 2006. The other PS3 has been plugged into a surge protector since 2008. I only turn them off with standby mode. The only time I ever unplug them is when I am plugging a new wire into them. Never any problems with either one. I am posting this with one of PS3's right now.
@ Brink-2-Chaos - Sorry but I disagree, power surges are not the cause of YLOD.
I have to disagree with you.
I have seen my cousings PS3 YLOD in front of my eyes on a power surge. 5 minutes later it was raining cats and dogs.
When I used to fix PS3's (reflows and cleanings), I would get a few PS3's in that have YLOD from power surges as well.
The odd part is that you would think replacing the power supples would do the trick.... nope. A reflow was needed.
Not to say that its a common occurrence, but its not uncommon at the same time.
I found some of this thread to be quite funny,if you got YLOD and it was fixed by just simply a reflow or reball then it was NOT i repeat NOT caused by a surge,it just dont work that way..
Now a surge can cause you to get YLOD but it is going to possibly fry the power supply and if the surge is bad enough because your home has a poor ground or none and was a lightning strike surge then it would go beyond the power supply into the cpu,gpu,memory etc..and no amount of reflows or reballs will fix one of these..
this is why you should always use a surge protector on expensive equipment and they are fairly cheap these days...
Plugged into at least a decent surge protector (3 PS3's from: late 2008 to 2012.)
They are always Red Light - Standby if not ON being used. Else unplugged to move for whatever reason.
I use the settings to have them urn off after a couple of hours of non-use. I also have my plasma's set to turn off after some time of non-use (You know how many people just leave Netflix or Vudu open on a search screen? Too many in my house!)
