Hi, everyone, need a suggestion here. My PSU : Seasonic 620W is kinda old, almost reach 6 years already. Now to the PSU started to have this subtle buzzing sound, not sure what sound it is but it kinda annoying to leave the pc on idle but have that sound in my room. Below is my spec
Ryzen 7 3700X
MSI B550M Mortar
Corsair Dominator RGB 3200Mhz 8gbx4
Asus Strix GTX1070
Samsung 960EVO 500GB
HDD 1TB x 2
HDD 2TB x 1
SSHD 1TB x 1
4 Corsair LL120
2 Corsair stock fan
1 Corsair Lighting Node Pro
1 Corsair Lighting Hub
should I be worried of the sound coming from my psu ? If I were to change the PSU, which PSU is recommended thinking in future I might upgrade to a RTX3070 at least ?

(a recording would be useful here)  Coil whines are not something to be concerned about  If you plan to go for a 3070, look for a quality 550-650W unit, something in the line of the XPG Core Reactor/Enermax Revolution DF/Super Flower Leadex III/Corsair RM should do very nicely here is the video

Number of downloads: 24i guessed it's a coil whine ? since it's a 620W psu, if I were to upgrade to a 3070, can it sustain the load ? or I should upgrade together with a new PSU, saw a shop at shopee sell the XPG Core Reactor 750W for RM458, is it a good price ? |

QUOTE(chocobo7779 @ Dec 15 2020, 06:45 PM) Sounds like coil whine for me Yes, it will handle a 3070, but do bear in mind that you might want to swap to a newer unit as yours is an old, group regulated unit, which isn't very suitable for modern systems anymore The XPG Core Reactor is a great unit, so go for it if you can (although a 750W unit would be massively overkill for a 3070) i see, thanks for the suggestions, will consider those power supplies  |
