I had to buy a new power supply, because my old is always lubricated, so I once rumgegooglet etc. Often read the be quiet! and Sea Sonic to be good, but they were also correspondingly expensive. Then I got this power supply found, which is of the same brand as my Tower, I habs been thinking and ultimately ordered but, luckily! It's really nice and quiet, in my view and does everything it promises. I've heard of it, that does not address some power supplies immediately if you have the computer into a power strip, which can be switched on and off. I do in my power strip and the PC starts up immediately.
Conclusion: Super power supply with great price / performance ratio!
