Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

Reviews
400W Seasonic Platinum 400 Fanless, Full Modular, 80PLUS Platinum, Single Rail, 33A, Fanless, ATX PSU is rated 4.2 out of 5 by 5.
Rated 5 out of 5 by from no noise Completely silent, no fans. You'll forget there's a PSU in your PC! Modular design so you can connect only the cables you need for your system. Feels weighty and well made. Make sure you have a case where the PSU sits at the bottom for ventilation purposes (vent facing upwards) / or if it does sit near the top of your case allow plenty of room above the vents to allow heat to escape.

Rated 5 out of 5 by from A wonderful piece of kit This PSU was bought to go in a silent system and it has not disappointed. You can tell the second you take it out of the box that you're handling a high-quality PSU - it has weight, it has heft, if you threw it at someone it would do some serious damage. It's modular, which made installation a lot easier, and I had everything hooked up in the usual amount of time with no difficulties from the PSU. It's been chugging away quite happily for around 2 years now, no noise, no complaints. Price-wise it's not the cheapest, but I have learned that a PSU is not the area to cut corners on if you are on a budget. It's of great pedigree, performs well under pressure (according to reviews by people much smarter & better equipped for testing PSUs than I am), and of course being modular and silent adds a little to the price tag. Overall I feel like it's a very fair price for what you get. Oh, and in case you're wondering if it fits in the Fractal Design Node 304 case - it does.

Rated 1 out of 5 by from Poor! Don't let the fancy packaging fool you, my unit did not last the month, started getting awful buzzing noise from it, my old psu fan was more quiet, was told the buzzing was normal for fanless seasonic not for me it's not, will not buy seasonic products ever again!

Rated 5 out of 5 by from What a product They must have spent a fortune on the packaging , like i had bought a bag of gold the way it was wrapped , this tells me that its a quality piece of kit and i was not disappointed ! no noise what so ever , great in my HTPC

Rated 5 out of 5 by from Excellent PSU and no noise! I cannot recommend this PSU enough. I bought the Seasonic Gold fanless PSU about a year ago from Scan and was amazed at the reduction in electicity consumption on my computer - over a third reduction when the machine was in the same state. And this was in comparison with a very effective, quiet PSU. I now expect the Platinum to be even more economical. If you want to save on power usage and eliminate PSU noise, then this is the power supply to buy. They might seem expensive initially, but they are quality built and the payback is rapid.
