comment What about placing a voltage regulator behind an UPS with modified sine output, to protect an active pfc psu?
@Sarmes: Are you sure that these higher end UPS models will actually work out that much more expensive for you? Firstly you won't need to buy any voltage regulators (which probably won't help anyway) and secondly you should be able to plug in more PC's to one unit than you could with a cheaper model.

Wikipedia even has a picture of the waveform of one of the models (SMT1500I) at en.m.wikipedia.org/wiki/APC_Smart-UPS

@Sarmes: Different UPS models will obviously produce different results. I suspect that the two that were tested were low end models. If you contact APC, they should be able to confirm that Smart UPS range is fine for PFC PSU's. Also they offer a connected equipment guarantee that means they would be liable to offer compensation if your device was damaged.

comment What about placing a voltage regulator behind an UPS with modified sine output, to protect an active pfc psu?
To my knowledge, the sine wave approximation only occurs when running on battery power. When the mains power is connected the output should be similar to normal AC. My UPS causes a buzzing sound due to sine wave approximation, but only if I disconnect the mains. If you buy a reasonable make and model (e.g. an APC SMART UPS, about $500) then I really don't think you should have any problems since people are using them all the time for critical situations. The cheap consumer voltage regulators you are talking about do not turn the input into a pure sine wave, they simply prevent spikes.

comment Sudden massive system temperature spike
Do you have a screenshot from the temperature monitoring program? You mentioned "system" and CPU temp but have you checked GPU temperature? Also, are you sure your PSU is sufficient for the new graphics card?

comment Can a website tell what device you're using?
I don't think that is what he is asking. He is talking about whether a website can tell if you are the same person/device if your IP address changes, not whether a website can tell what hardware you have.

comment Baby monitor interfering with wifi
@saltcod: I'm not sure I understand what the problem is. Does the Netgear router have the same problem as the Actiontec one when running at 2.4GHz?

comment “Weak bits” test for flash drive?
A hard drive / SSD provides real-time diagnostic data via SMART to help give you an idea of whether a failure is imminent, whereas a pen drive does not. The flash controller chip in the pen drive abstracts away all the details and normally has no way to to communicate it.
