    older psu with dual 12v rails. Do both rails power the cpu?

    I have an old Earthwatts 380 which was built by seasonic. Has dual 12v rails at 17A. specs say one 12v powers motherboard and peripherals, the other 12v powers cpu. but with it all plugged in, do both 12v rails power the cpu still? i mean how many amps are available to the cpu?

    I suspect the realtek gigE on my laptop crashes my cable modem. Is that even a thing?

    I've noticed that when I saturate the builtin realtek gigabit ethernet on my asus laptop with multithreaded downloads, or try to max out my internet connection, occasionally the modem will crash, requiring hard reboot of modem. when using several different computers with Intel gigE, I haven't...

    12600k 12700k already getting big price cuts.

    hot dammit. if it didn't cost $20 in gas to drive to microcenter, I would be all over this. I paid an early adopter tax on my 12600k system. Though I did get a partial refund for the price drop from newegg. Came out to similar cost if you factor in the time and gas. Lucky for anyone near a...

    acid vapor kills hard drives

    I made the mistake of storing some old hard drives near a closed container of diluted tca acid. I later discovered the acid destroyed the seal and the acid evaporated, some of it wafting by the hard drives. Both hard drives are dead. They were working before this incident. Should've sealed the...

    how well does window position saving work in windows 11?

    biggest annoyance about win10 is whenever I turn off my 4k tv monitor (connected to laptop) overnight, it throws most of my windows to the upper left corner of the screen when i turn on my tv the next day. sometimes it doesn't do this even after many hours pass by, but sometimes it does this in...

    5700G vs i7-11700. Intel needs about double the wattage to achieve similar results. transistor shrinkage can't come soon enough.

    11700 reviews seem rare. Didn't test much, but i have 2 prebuilt towers with a 5700g and 11700, otherwise identical. At idle, they use about the same amount of power. I don't have a killawatt, but my clamp meter read about the same 0.26-0.28 amps at idle. but under load running cinebench23...

    why is AMD always behind on video decoding support? if decoding is a separate module?

    vega 8 came out around the same time as nvidia's 10 series. my gtx1060 supports vp9 decode at 8k60 whereas the vega 8 maxes out at 8k30 vp9 decode support. Seems to be the same deal with the RDNA2. nvidia and Intel Rocket Lake Xe support 8k60 AV1 decoding, whereas the RDNA2 tops out at 8k30...

    ssd partitions and longevity?
