Default Fake SAMXON cap in Corsair PSU?


Iīve just recapped (and fixed, more of this later) my Corsair CX430 V2 power supply, and found one of the capacitors not looking like the rest in the SAMXON GF series. Please see attached photos.

All the GF's are dark green and one is light green. The difference is greater in reality compared to the photos. Also, the bung is different. Might this one (the 3,3mF) be a fake you think...?

NONE of the caps was within limits when tested with a professional bench LCR-measuring device, especially the small Jun Fu 1uF 50V had an ESR of whopping 3 kohms. The SAMXON's were either low on capacitance and/or high ESR. None had bulged. The power supply has been in light use for about eight months 24/7 prior failure. The symptom was that the computer didnīt start at all, only the fans and hard drive spun up.

Iīve recapped it with various Rubycon ZLJ's, Panasonic FM, Suncon WX, ELNA's and UCC for the small caps. Thatīs what I had available at the time... Want to see the end result to? OK, Iīll attach one more photo

What do you think?
