Dead silent
When I looked on Seasonic's website it said 6 molex connectors. This has only 4
Perfect for my storage server. Can't hear the fan at all. Plenty of sata power connectors.

Experience: 6 Months
Quiet, Cool, Efficient
Very reliable power supply. Runs cool and quiet like all Seasonic PSUs. Would definitely consider purchasing again.

Good warranty
I bought this a week ago on sale for around $60, not really a great deal but the 5 years warranty evens that out. If you want a quiet PSU with good efficiency then this might do the job.

Experience: 7 Days
-Seasonic Quality
Bought this PSU for my HTPC build and so far so good. I have another from Seasonic in my main PC and I will never buy another brand. These things are bullet proof and have the warranty to back them up. Highly recommended.

Silent PSU! (well I should say quiet)
A bit pricey for 520W
I was building a quiet PC for a friend and this was on sale for 50$ and it does an amazing job at keeping the system quiet and powered lol... good cables, solid, heavy... nothing more to say... it's a PSU and you need one...

Not much of a noise producer and works great..
I have been using it for a gaming rig and I have no problem at all until now.. Consumes energy and is perfect for a decent gaming rig!

Très bon manufacturier.
Très silencieux (presqu'inaudible).
80 Plus Bronze.
Garantie de 5 ans!
Condensateurs Japonnais de 105°C.
Un vrai bloc d'alimentation de 520 avec 40 ampères (480 W) total sur les deux rails de 12 volts.
Compte tenu de la qualité le prix payé en solde de 50$ est très bon.
Rien à dire de négatif sur ce bloc d'alimentaiton de bonne qualité.
J'ai acheté à plusieurs reprises ce bloc d'alimentation. À chaque fois, la première qualité que j'ai noté au démarrage de ce bloc d'alimentation c'est son grand silence. Il faut s'approcher l'oreille pour entendre tourner son ventilateur. En mains on sent la qualité de fabrication Seasonic. Avec une grande efficacité de plus de 80% certifié il est certain que l'échauffement de ses composants sera limité mais malgré tout Seasonic a utilisé des condensateurs de haute qualité faits pour fonctionner à 105°C. Les chances pour que ce bloc ait une durée de vie plus longue que l'utilisation que j'en ferai est immense... Pour ce qui est de sa puissance, elle suffisante pour alimenter n'importe quel système actuelle avec un CPU et une carte graphique haute de gamme sans broncher. Personnellement je l'utilise dans un système qui comprend entre autre un processeur AMD Phenom II X4 955 BE et une carte graphique Radeon HD 6870 et il me reste beaucoup de marge pour overclocker au maximum ces composants si je le désire. Un très bon achat à recommander.

solid performance
reliable quality
price a bit higher than some
Seasonic is always worth to buy, cannot go wrong with it. Altough the price is a bit higher, you may but a 620 or 650 with a free dollars more for other brands. But for seasonic, never need to worry about power issue.
