    NZKshatriya got a reaction from Scania556 in PSU makers that have janky warranties   
    This is false when it comes to a properly discharged PSU.
    And there are more than enough users out there that know how to do this.

    I saw that my pre-built case had a 92mm fan vent but mounting holes and the front panel cover blocked air flow. I cut out 92x92mm square and drilled some mounting holes.

    NZKshatriya reacted to mariushm in Good ups that can run a 1000w platinum psu?   
    Just in case it's not clear or obvious... the UPS rating in VA is NOT the same thing as the maximum power it can supply.
     
    A 1000 VA UPS can not output 1000 watts continuously, or is not supposed to - the internals may be oversized, or if you're lucky they use the same components as bigger models and just label it with a lower rating.
    That's why you'll see some UPS models say stuff like 1500 VA  true sine power output max 900 watts or something like that. 
     
    You're looking at peaks of 320 watts for the 3080 without overclocking, let's say it peaks at 350 watts when overclocked. 
    A processor like the one mentioned will peak at around 150-200 watts, if you overclock it heavily it may go to around 250 watts.
    You're looking at around 20 watts for the fans and water cooling and maybe 20-40 watts in 3.3v and 5v for everything else in your computer (rgb strips, onboard audio, lan, ssds, keyboard, mouse, other usb devices etc)
     
    So let's say the components pull peaks of 650-700w.  A platinum efficiency psu will produce these 700 watts with around 92-94% efficiency... let's be conservative and say 92%... that means the 700w were 92% of what pulled from mains... so the psu actually pulls around 750-760 watts and around 50-60 watts are lost as heat in the psu.
     
    When power is lost, the UPS has to take 10.8...13.8v from lead acid battery and uses an inverter to produce 110v AC or 230v AC... that's done with around 80-90% efficiency. So that 750w becomes around 800-850 watts of DC power pulled from battery. 
    So you can easily do the math ... 850 watts / 10.8..13.8v = 62..78 A of current pulled from a 12v lead acid battery... the current increases from that 60-ish Amps and goes up as the battery voltage goes down. 
     
    The cheap 500-750 VA UPSes use a single 7-9Ah lead acid battery... let's say a 1500 VA UPS uses a bigger 20Ah battery, here's a standard UPS battery : https://www.digikey.com/en/products/detail/zeus-battery-products/PC20-12NB/12570398
     
    Here's datasheet: https://www.zeusbatteryproducts.com/wp-content/uploads/downloads/ZEUS_SPEC_SHEET_PC20-12_RevV2.pdf
     
    you'll see there :
     

     
    So with such 20Ah battery, pulling 800w or so, you'll get maybe 10 minutes of running on UPS ( looking at around 50A because I assume as soon as the power goes off, you'll minimize the game or have Windows "power management" to throttle the cpu and reduce power consumption ... so you'll have that peak current when gaming for let's say half a minute to 1 minute until you realize the power failed and pause game and then the power consumption should drop to whatever's idle, average power consumption of 200-300w
     
    The above battery charges at up to 6A but it's not a good idea to use such high current, a ups most likely charges at around 2-3A ... you'd be looking at around 8..10h to charge this battery when fully discharged. Says at the top in datasheet.
     
    So the reason I suggested an UPS that uses two batteries, is because most likely such UPS will have two 9Ah..12Ah standard mass produced batteries, easy to replace when dying, and if the power fails when you're gaming and your PC pulls a lot, the two batteries share the load, so each battery sees half the current, or only around 20-30A instead of one battery being abused with a sudden 800w pull (around 60A)
     
    Even better choice would be one of those rackable UPSes which use up to 4 lead acid batteries as they're designed to work either from datacenter 48v DC or from mains. 
     
    You can find refurbished / used ones with or without batteries for cheap, like 100-300$

    NZKshatriya reacted to Catsrules in Why cell phones don't get generic OS installers?   
    How many people install OS on their computers?  Normally people buy their computer from the Dell, HP, and Lenovo. Yet none of them really provided OS updates. It is all handled by Microsoft.  It doesn't matter if Dell doesn't support my laptop anymore because Microsoft fully supported windows 7 and then was nice enough to provide a free upgrade to Windows 10.
     
    I am just wondering why we don't have this same type of partnership with Google and Phone OEMs.
     
    Edit I should mention I do think Google pushes out some security updates via the play store. But it is nothing like was Microsoft has with Windows.

    If the repair is ~50% the cost of a new board, its better to just get the new board.

    It looks to me that the new thermal paste was applied with the safety latch holding the cpu in place raised.
    This would allow for the twisting motion that is evident on the pins on the socket itself.
     
    I am pretty sure there is at least one broken pin still in the CPU itself, else it fell into the board somewhere.

    I Appreciate The Help.
    It Does Power On, Fans Start Spinning, PSU Has Power. It Was Working Until I Changed The Thermal Paste... Upon Changing The Thermal Paste, The Screen Will Not Show. if I Turn It On It Starts And Everything But It Stays At A Black Screen. The Black Screen Changes If I Unplug The VGA Cord Then The Monitor Counts Down To Sleep Mode, Which Tells Me There Is Probably Some Kind Of Signal. But It Just Stays Black Screen. I'm Using An iGPU Right Now. So The Pins On The Motherboard Are Fine?

    NZKshatriya reacted to Bombastinator in Apple being sued for refusing to help iTunes gift card scam victims   
    Everyone is stupid and falls for scams.  Even you. Everyone is “stupid” when they’re not paying attention, and almost no one can do that all the time everywhere and stay sane.  Hyper vigilance creates insanity.   This is one of the secrets of the problems of pure capitalism.  It assumes perfect information and perfect behavior instantly all the time.  Doesn’t make allowances for time.  Pure capitalism was used in the us once.  It worked so poorly it nearly killed the country in something like 20 years. 

    The claim is that Apple was giving out false information which resulted in losses not that they refused to pay.
