Hi,

I recently updated my graphics card to the MSI GTX 780 ti and have noticed that my power supply has become more noisy than usual. The PSU that I am currently using is Corsair HX750v2 ATX

I also noticed that the PSU fans run at 100% all the time time I play Crysis 3 which is loud and very annoying. Before the PSU was silent and I was using the MSI GTX 680

Is it possible that I need a bigger power supply for my PC or is my current PSU faulty?

If I need a new power supply, can anyone recommend the most silent and coolest PSU possible for my PC case can accept PSU's up to 180mm

Below is a list the system I have.

Windows 7 Ultimate 64bit
MOTHERBOARD: Asus Maximus V Gene
GPU: MSI GTX 780 ti
CPU: Intel i7-3770K @ 3.50GHz Ivy Bridge
CPU COOLER: Noctua NH-D14
RAM: G.Skill Trident-X 16GB Kit (8Gx2) DDR3-2400
SSD: Samsung 840 Pro Series 128GB SSD
HDD:WD 3.5" Black 2TB 7200rpm
PSU: Corsair HX750v2 ATX
FAN: Noctua-P12-PWM 120 Case cooler fan
CASE: Temjin TJ08-E

Any help will be appreciated.

Thanks,

Nik

If your not getting restarts or lockups then I would say the unit is fine. Try using a can of compressed air to blow some dust out of your power supply before you buy a new one.

Yeah, my PSU is located on the top of the case, and thats where all the noise is coming from. GPU fans seem normal
