Having trouble choosing a relatively quiet PSU for my HTPC build, I am using the following
Lian Li PC-C60B w. Stock Fans (140mm x2 - rated 17-17db @5V / 20db @ 7V)
Intel I3-2100 w. Stock Intel Cooler
Either HD4670 or onboard HD2000 video
750GB system drive, eventually to be replaced with an SSD
2x 3TB WD Greens (Eventually plan to have 5-6 of these in the case)
Even though I have lots of HDDs they will be relatively quiet, because I will use a snapshot RAID system, so only 1x HDD will be used at a time.
Eventually I will probably switch out the Graphics card for a passive card or a card with a low spinning fan. I intend to run the stock case fans at their lowest setting. PSU prices and availability is quiet different in NZ. The Lian Li PC-C60B recommends 140mm (5'5") sized PSU if using both HDD bays, altho I could probably just adapt the bays to only use the front bay which gives me 5x 3.5" HDDs and I can palce a 6th HDD in the 5.25" bay, thus letting me use a larger 160mm PSU.

Antec HCG-400 (Bronze) - $80 to $100
Antec HCG-520 - $95
Seasonic S12-II 430W - $125
SilverStone Strider Plus ST50F-P 500W (Bronze) - $120 to $135

Seasonic S12-II 520W - $140
Seasonic S12-II 620W - $150
Seasonic M12-II 620W (Bronze) - $160
Corsair TX550M (Bronze) - $155
FSP Group Aurum 650W (Gold) - $170
Corsair HX650 (Bronze) - $180
Seasonic X-400FL 400W (Gold) - $180
Seasonic X-660 660W (Gold) - $220 <-- Too expensive
Antec EA-380D - may be too loud as it only has an 80mm fan, also the design means it has to draw air from inside the case, rather than having an air intake on the side to take in fresh air.
Antec HCG-400 - might be a good buy, it is 160mm in length so I couldn't use the 2nd HDD bay, it has the same fan as the HCG-520W, ADDA ADN512MB-A90 135mm which is rated at 18db @ 20% Load, 20db @ 50% Load, max rpm 1700 - see here
Antec HCG-520 - 160mm length, Fan = ADN512MB-A90 (135mm, 12V, 0.27A, 1700RPM max, 30 dBA)
Silverstone Strider ST50F-P - Small size 140mm length + modular. Some people say the fan is too loud, yate loon d12bh-12 max rpm 2300, some reviews said it was quiet, but it seems they changed the fan. Fan noise is 20db at idle up to 50% then jumps to 26db. Ideally I'd like to choose this PSU but I'm worried about the fan noise.
Antec TruePower New Series TP-550 - size 150mm length. Fan is 120mm ADDA AD1212HB-A7BGL max 2200 rpm; 20% Load 18db 50% Load 20db 80% Load 23db
Seasonic S12-II 520W - 140mm length, Fan 120mm ADDA AD1212HB-A70GL max2050 rpm , Fan Speed 600pm up to 150W, 800 rpm @ 200W, 1100 rpm @ 250W, No comments on the fan noise. Another review stated the fan speed was only 800rpm up to 70% load - here
Seasonic S12-II 620W - 140mm length, if it is the same fan as the M12-II 620W then the fan stays below 1000rpm up to 300W
Comments, which PSU should I buy, I'm leaning towards the Antec HCG-520 @ $95 , Antec TP-550 @ $120 to 140 , Seasonic S/M 520/620W @ $140 to $160.
HAS ANYONE GOT ANY EXPERIENCE WITH THE ANTEC HCG-520, it's almost half the price of the seasonic.
