SeaSonic Electronics PRIME Ultra SSR-850TR Reviews
Rock Solid Voltage
When I built my first pc with brand new XP I used PCPower&Cooling 510 PSUs. Great but noisy! Their silencer series wasn't much better. Switched to Seasonic and have not needed to look back or research to change brands again. In my FT-02 I can not tell if the fan even comes on, it's set up to. Every E is slightly hot, like .02 or .03 but I consider that a strong supply, my mb will correct if need be. THE most important part of your rig is the psu!
Seasonic has been the best for decades. Will not buy any other brand. Just replaced my 10 year old version of this. It's still running great just wanted a new one so I can make another computer with the old one.
4.75/5 PSU power cords could be a lil longer
Longterm could easily deserve 5 stars, but new owner. I have a good sized case and for cord management can run the cords on backside of case for cleaner look. The cords to the processor power are maybe an inch too short to comfortably run behind the motherboard, so have to take a lil off the top of score for that. Quiet. Price is maybe a lil bit high. Longterm though again, that may be meaningless. Would recommend.
SeaSonic Electronics Prime Ultra Titanium Series 850W 80 Plu
SeaSonic has great products. Their titanium series has the highest efficiency rating, and is backed by a 12 year manufactures warranty. My order shipped quickly and arrived undamaged.
This is a very great product that I don't regret purchase and it has served me really well. I'd recommend purchasing this for any computer or whatever needs you would want it for. This top of the line part will for sure make you happy.
Quiet and very efficient. The PC power draw went down by 20W at the wall during gaming sessions! Due to high efficiency it stays cool and doesn't need active cooling. This translates to increased safety and piece of mind which for me is definitely worth the extra buck.
SeaSonic never disappoints.
Been buying their PSUs for many years, and this one feels excellent yet again. No doubt it'll last for a long time, and has all the connections you could possibly need. Very pleased :)
No Compromise PSU
Decided to finally upgrade from my 1st gen I7 system to 12th gen alder lake. Designed my new system with a custom WC loop for ultra quiet running. Everything worked out fine until I realized that my existing, cheaper PSU was now the loudest part of my rig. After some deliberation I went ahead and replaced it with this Seasonic unit and havent looked back. It runs silently or near silent most of the time thanks to its efficient design and fan curves. Can't beat the 12 year warranty either.
