I haven't seen anyone address the capacitor question. This is a very valid question. Dirty power reduces the life of electronics. And these components are not cheap. I personally asked customer support this question and here is the answer I was given.
Comment: I have an EVGA 1300 G2. I have 2 questions. 1st, the head snapped off one of the mounting screws. If I am unable to grab what is left with pliers, will my warranty be voided if I open the case so safely extract the broken screw? 2nd, I would like to make a custom set of sleeved cables. The OEM cables have what looks like it could be a capacitor installed under the heat shrink. This is not something that would look all that great on individually sleeved wires. I know EVGA offers sleeved cable that don''t appear to have a capacitor inline. So... Can I safely make cables without a capacitor installed inline? I would have thought it was there for a reason. And I really don''t want to replace a perfectly good PSU just to make a set of cables. Thank you for your time, Brian.
The screw stuck would not void the warranty but opening the power supply would and is highly not recommended.
You are able to make your own sleeved cables if you would like. The cable set you offer is a better gauge wire which does not require the capacity like on the stock cables.
Thank you,
EVGA Support
This is copy and posted from the email. I'm having a hard time buying into this answer. Anyone else? I would LOVE an engineer from EVGA to comment on this. I read a review on JonnyGURU about a non EVGA PSU that also used capacitors in the harness. This PSU did very well when tested in the "as shipped" form. The reviewer swapped out the harness for ones without the capacitors and the results were a 29mV ripple!
