850W, gold certified, cheap, fully modular, +1

Got a great deal on it and its 80+ gold probably a bit overkill but it was worth it and it has a 10yr warranty. Cables are sleeved and look good and are easy to manipulate where you want them.

Perhaps is still where is put it in the case as the system works - I have never heard from him again :-) good quality, quiet and stable, long guaranty, plenty of power ...

I think I actually got this one for 81$? IDK, forgot about the promo code cuz I bought a bunch of things in one order. JonnyGuru gave this model a very high praise and I know SeaSonic is not going to let me worry about this one. And it's also cheaper than many other 80+ Gold fully modular competitors. Highly recommend this series.

Modular, gold, tiny - really nothing to complain about.

Best PSU on the market if you ask me AMAZING customer service the cables are sleeved in a nice black sleeves and they aren't as stiff as other PSUs I've used and its more than enough for what i need.

SeaSonic FOCUS Plus Gold 850W 80+ - I was recommended this product by another member after purchasing the EVGA GQ 750W psu. It went on sale for 5 dollars more then I paid for the 750 so I jumped on it immediately.

Looked at JohnnyGuru and saw that it is a good unit. Got a good deal on it @ Newegg.com Black Friday week.

It is compact. That's great. That way I had plenty of space to do my build with the AIO in the Front and still room for HDD rack. So far it is running pretty silently. Price/Performance was unbeatable
