Found this on HardOCP:


Same as the other components - the fan only comes on when it has to, and when it does I can't hear it. Really like it. Came in cool fancy velvet case with a nice looking case badge. Had all the modular cables I needed. Documentation was good and just felt like a solid product.

Future-proofing until we get portable nuclear reactors for over 100% power efficiency.

Modular, and was deciding whether to go for just the gold rated one, but this was in stock and decided to try titanium rated since I'll probably be using this system for a long time too. 750w seems just nice for me since I have no plans to SLI.

Totally overkill and unnecessary, but I wanted Titanium efficiency and the available ones didn't differ much in price. Wish they had upgraded the cables (only the 24-pin is braided, the rest look OK but are stiff) instead of including the velvet bag and mirrored accents on both the PSU and box...

I really like this Power Supply, it is quiet, high quality, and a very good unit in general.

The fan doesn't spin most of the time. It's cool and very quiet and extremely stable. It holds my overclock quiet well. It was rated 10/10 on the JonnyGURU site.

One of the best power supplies ever made.

One of the most stable PSUs in the market, guaranteed*

Your PSU is one of the most crucial aspects of your build, and you should consider this an investment, together with a properly rated UPS.

I guess, SeaSonic backing it's PRIME line 80+ Titanium rated PSUs with an industry unheard of 12 year warranty is enough said.

*Check out JonnyGURU's review; for this, or any other PSU that you are into the market for. He is one of, if not the most prolific PSU testers that base reviews & results on actual, industrial grade hardware, not guesswork, software, or straight pulling ratings out of their @@@@@.)
