I'm searching for a power supply unit for my computer:
MSI Z87-G45 Gaming
Intel Core i7-4770K @ 4 GHz
Corsair Vengeance Pro 8GB PC3-12800 1600 MHz CL9 x2
MSI GTX 770 Gaming 2GB
Western Digital Blue 1TB 64MB
Samsung 840 Evo 250GB
ASUS DRW-24F1ST
Corsair Hydro H110
5 mixed Corsair case fans
My estimated max load is less than 500W.
My (actually measured) gaming load is only 300W.
I want some margin for overclocking and upgrades (what does the 4770K use at 4.4 GHz?).
I want it to be quiet at 300W! (30 dBA maximum)
Done.
I’ve been considering going as low as 550W (Seasonic G-550).
Bigger units don’t usually have lower noise minimums unless they have Zero RPM-modes. I’ve tried two of the Corsair HX1050 v2 that allegedly use Zero RPM-mode up to 300W but quickly discovered that wasn’t the case at all and at loads somewhat less than 300W it would start spinning every 10 minutes and go up to 100% (40 dBA, loud) and at 300W constantly it also spins at what sounds a lot louder than their own claims of 20 dBA… in other words I don’t trust Zero RPM a lot. Their new RM1000 unit claims to use Zero RPM up to 400W but I want to try something other than Corsair before I challenge that. Can’t wait to return my $259 HX.

Good luck with that
