Ive had my nvidia gtx660 which requires a 450w psu with a minimum of 24A to the 12v rail.

Running this GPU since i bought it a few months ago, is my OCZ Fatal1ty 750w that Ive had for nearly 2 years now,

Mine is on the bottom of the page under the legacy drop down.

So I have four 12v rails with 18A each and apparently a total amperage of 54A combined.

So does this psu comply to my GPU?

I ask this because recently my PSU started chirping like it has an inductor thats going bad. This chirping is very new unlike the coil whine ive always had but I know it isnt bad.

So help me trouble shoot guys wether my psu is just going bad or maybe I wore it down using a more powerful gpu.

My set up is a AMD fx 8 core 8120
16 gigs of ram, 500g HD, h80i Corsair water cooling, and for my mobo is an Asus m5a97 R2.0

Id really appreciate the help!
Its mainly to know wether or not when I warranty my ocz that I need a stronger psu or Ill be able to insert my new Fatal1ty in to my rig when I receive the RMA'd one.

Thanks!
Brandon

A 750w PSU would be more than enough for the GTX 660 and should not be causing it any stress. The 54a is also more than enough.

it should work, it's the total 54A that matters.

So basically the new chirping could be my PSU slowly letting go? Because i researched it being a inductor that is wearing out.

Lately my HD started going defective also, Im wondering if maybe my PSU started damaging my system.

A Geforce GTX 660 - needs at least 24 Amps on the 12v rail and at least a 450w power supply.

You have way more than enough power to run a GTX 660.

Thanks a lot for helping me confirm my psu being good enough guys. You have no idea how much research I've been doing to understand how multiple rails on a 12v works/combines.

Thanks so much.

Over time components can become defective from constant use , with the PSU possibly going defective it's unlikely it would just affect the HDD , most likely it would affect other parts as well. You may just have two components going bad at the same time.
