We're talking about power supplies, of course. For the uninitiated, electricity comes from the wall at 120 V AC (or possibly some other voltage, depending on where you live), and computer components need power at much lower voltages and DC. A power supply does the conversion for you (or at least AC to DC with some voltages), and a computer needs to have one in order to work.
And more to the point, a computer needs a good power supply if you want it to reliably keep working. Some vendors will have high end power supplies that they send out for reviews to try to establish a good reputation, and also sell much cheaper power supplies that are a danger to fry your system.
The occasion for today's post is that Seasonic has launched a new flagship, the PRIME Titanium (their caps, not mine). Seasonic is not one of those vendors who will sell you junk, as even their low end stuff is decent. But for several generations now, from their X-series to their Platinum series to last year's Snow Silent, their top end power supplies have been arguably the best consumer power supplies on the market.
The industry has recently moved from 80 PLUS Platinum (92% efficient) to Titanium (94% efficient) as the top end energy efficiency in power supplies, and a number of other vendors got units out before Seasonic:http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100007657 601115166
But while some of those are nice, others have only excellent energy efficiency to go with less then excellent voltage regulation and ripple suppression. No matter how efficient it is, a power supply that delivers unstable enough voltages to damage other hardware is junk. Now, I don't know if any of the other Titanium power supplies are that bad, but merely staying in spec isn't enough to justify a premium price tag.
So while Seasonic wasn't the first with a Titanium power supply (nor Platinum), they did take the time to do it right. Behold the glowing Hard OCP review:http://www.hardocp.com/article/2016/07/21/seasonic_flagship_prime_750w_power_supply_review#.V5ORv1KEB10
It sports voltages that basically don't budge as the load changes, ripple that is barely there, efficiency that touches 94.9% at 120 V, and a high quality fan that you can't even hear. Back it all by a 10 year warranty and make it fully modular, and what's not to like? In this season of paper launches of hardware, it's even available today as the first reviews go up:http://www.newegg.com/Product/Product.aspx?Item=N82E16817151158
Oh, right, that's what's not to like: the price tag. $160 plus shipping for a 650 W power supply. But at least they did make a 650 W version appropriate for gaming rigs rather than starting at something ridiculous like 1200 W. You can get a pretty good power supply for half that price, but that price tag is just about the only real reason to get anything else.
