Why do you need 1000 watts? You got a 4090 or a 5090? Otherwise a 750-850w PUS is more than sufficient.

But yeah if you got screws loose inside your current PSU... don't risk shorting out your whole system.

Coil whine has nothing to do with damages of any kind.

watts is not volts
the psu will only output as much power as the pc needs upto its rated wattage
at that mark it may be unstable or turn off when it trips its protections

coil whine does not damage anything, its just audible noise from the choke coils in the psu, nothing you can do about it

changing gpu/cpu loads can change its frequency and volume

a higher wattage psu does not mean it will not have coil whine

a higher wattage psu can be more efficient at the pcs load
most are best around 50-80%

It’s always better to buy bigger psu, since the output is not always 100%

There is really no reason for you to buy a extremely high voltage psu if your computer doesn't use that many watts. But there is no problem in using it, one thing you have to check is if your psu has all the certifications and is a good quality one, 80 plus bronze is already good enough if you have a decent pc, and always search for PFC active psu's too.

most psus sold in the us are good for around 90-250v
80+ gold will be active pfc

but 80+ is easily faked

best to stick to known good brands/models
evga, corsair (non v), seasonic, bequiet

coolermaster, thermaltake are a mixed bag, some good but they are often overpriced, and most are junk

I think it was 2 times a screw landed in my asus psu. I told not to remove it because of the Arc that could fry me to death.

A Gold or Platinum 850W is all you need and even that will be more then enough.

Look at the latest models available from Corsair and BeQuiet. Unless there is a good sale on 1000W, then 850W is fine

Yeah those capacitors hold a charge for a good while don't bother just get a replacement and learn from previous mistakes. Imo a 750w PS is good enough for your system from what I see.

850w like bad motha said is fine too. Imo go with a good quality PSU you can get at a good deal.

I wouldn't pay more than 100-120 bucks myself for an 850w.

I got a corsair one a few months ago for my new system 850w gold... with the 600w cable and its all detachable. Good stuff. 100 bucks or so.

taking apart a psu is not as dangerous as they say

if you turn off or unplug the psu, by the time you take it out and open it up, the mains caps (500v) will be drained low enough not to do anything harmful
you can use a screwdriver to short them to make sure, might get a small pop and thats it

like anything else, just dont leave it plugged into mains while working on it

not true hes pushing 700-800 watts with no overclocks personally i would go with a 1200watt platnium or gold since hes replacing anyway.60% psu usage is the sweet spot

4080 super = 320w
14700k = 253w
+100 mobo, fans and accessories
+100w overhead

total = 773w
you want to be around 20% overhead to keep the psu under 80% for better efficiency
773 / 80% puts it at 966w

800w would work, but 1000w would be ideal to run cooler and safer for future upgrades

I got my technician to remove the screws since I shouldn't be opening it myself due to high voltage. Just worried my psu won't have long life span or something like that.

Its a good one a asus thor 850watt platinum that cost quite abit. I like the rgb lights on it and you can see the led voltage light up on it aswell when powered on.

When im playing high demanding games at 165hz at 1440p with DLAA the watts hit between 400W and 500W.

I'll probably keep my 4080 super for 2 more years and upgrade to a 6080.
