Hi guys,

So, I bought this Corsair CX Series 750 Watt for my new pc.
(http://www.amazon.com/Corsair-Modular-Bronze-ATX12V-EPS12V/dp/B00ALK3KEM/ref=sr_1_4?s=pc&ie=UTF8&qid=1451670555&sr=1-4&keywords=power+supply)

The problem with the power supply is that it makes weird noise + shut down when I go the full mode

such as playing heavy games or running 3d mark tests.

I requested the replacement to Amazon already, but still.

not sure how a power supply can cause this such problems when it was only used for like

1~2 weeks.

Full stress tests on gpu and cpu showed that the noise isn't coming from either of them.

And, I can just get close to hear it from the supply clearly.

So, the question is if this company(Corsair) makes poor quality products mostly because I thought

they make fine and high end quality products.



I use

4790k
msi twin turbo gtx 950
16gb ram
Asus z97 a

I didn't overclock or something at all.

Sure it is weird. Probably just had bad luck. I've seen, that a lot of people go for the CX series, because it's cheap and seem not to have these kind of failures after such a short amount of time. Main difference is between low quality and high quality PSUs is the safety in case of a complete failure and also overall quality. But since you got a pretty nice CPU, which can take some OC, i'd stay away from the CX series anyway. :)

To answer your question: No, they aren't. Any company (well the big ones) make high quality and also cheap low quality PSUs, which you bought. :p
The CX series is, referring to the PSU Tier list, in the last tier (Tier 4) and should be avoided, especially in gaming rigs.
Tier 4 PSUs are likely to fail, when there's a lot of stress on it (high usage) and you also shouldn't OC on a tier 4 PSU.

But they also make premium top quality PSUs like the AX series.
