Wow.. Sub par caps...  I don't know why Corsair used Chicony for the OEM...  They should have stuck with CWT/Seasonic...
Still, why Corsair doesn't consider Delta as their OEM?  Antec has been using Delta for years...

We choose suppliers based on a number of reasons. For one reason or another, whenever we've come close to working with Delta in the past, we've gone another way. They make excellent power supplies, but then again, so does Flextronics.

We have nothing against Delta and may work with them on future products if the opportunity arises.

Hi, my 3 months used psu has ticking sound on power off. Is this a big problem? Should i send back for warranty?

I'm using corsair CS series

We have been notified, in limited instances, where some issues may occur when a FOCUS power supply is used in conjunction with certain high power consumption GPU or brand of VGA cards. If you experience possible compatibility issues, please check the below information and contact us for further assistance:

FOCUS PLUS & ASUS GTX970 STRIX: In very limited instances black screen may occur under heavy VGA usage. Current testing showed that certain VGA cards may emit higher than normal ripple when under heavy load and using a modified PCIe cables with enhanced shielding resolved the issue.

FOCUS PLUS & Vega 56/64: For units with serial numbers before January 2018, in rare instances, possible system shutdown may occur when GPU is under heavy load. This is possibly caused by higher than normal peak current emitted by this particular range of GPU's when under heavy load triggering the PSU’s internal protection safety.
