A large heatsink with dense fins quickly and efficiently dissipate heat, while highly reliable Japanese capacitors and 80 PLUS Platinum Certification lower the heat generation and enable its fanless design.

5 out of 5 eggsNO COIL WINE

Pros: The PSU is COMPLETELY SILENT. Unlike some of the fanless power supplies from seasonic, this PSU creates zero audible coil wine under full load.

Cons: not 750w?

Other Thoughts: If you are a silence freak you have to buy this PSU.

5 out of 5 eggsSilence and Stability

Pros: Perfect silence

Cons: connectors are rather tight fitting and have sharp edges

I never realized how loud my video card was with my old PSU

Other Thoughts: Handles my AMD FX6300 + GTX570 system without issue (and my Q6600 + GTX570 before that). My case is the Antec 300 with bottom mount PSU. The heatsink gets slightly warm to the touch.

The anodized heatsink is nice, but the PSU case is elsewhere covered with a rather thick/coarse paint job which may not be great for heat dissipation.

I initially bought the Seasonic 520W fanless, unfortunately it was not silent - constant buzzing audible at a distance. I did prefer the build quality of that model, however.

This PSU does make a clicking sound on startup/shutdown, but that's a non-issue for me. Be aware that once you get a silent PSU, the next loudest thing in your PC will stand out. For instance, my old PSU was masking the high pitched whine of the video card's fan... I replaced that with a Noctua 120. Then my CPU fan was the loudest... A few Noctuas later my PC is quieter than ever. Now I can hear the fridge located a couple rooms away.

5 out of 5 eggsNo problems after 2 months

Pros: Totally silent from a distance of 6 inches and vented on 5 of 6 surfaces.

I have this mounted in an Antec Solo II case in which the PSU mounts at the top. The case has a vent directly over the SilentNight's heat sink. The air radiating from the heatsink through the vent never feels warmer than room temp (27C/80F), even under a major load.

CPU is stock Intel 2500; Noctua NH-U12S cooler with 120 mm PWM fan and 120 mm Noctua PWM intake fan, both connected to the same CPU fan port on a splitter; both at about 800 rpm; single 120 mm Antec exhaust at 450 rpm. SSD and 2 internal HDDs. No video card. Prime 95 peaks at 67 on the hottest core. Intel XTU peaks at 63. OCCT peaks at 65.

Typical idle is about 36 degrees in this warm room. For kicks, I tested without any exhaust or intake fans: idle at about 46.

PSU will be transferred to Skylake build late this year.

I think the ports and cables are configured so that any cable can be used in any port.

Was able to attach all 4 internal drives to a single cable.

I got a substantial rebate check today, 10 weeks after filing.

BIOS set to quietest fan profiles possible.

Cons: None to speak of.

Gave off a mild odor for the first few hours of operation.

High priced if you don't get it on a sale or with no rebate.

I had to stash the non-detachable video card cable into an empty drive bay, but anyone who uses a video card won't have this issue. Cables are quite flexible, so it's an easy work-around.

Rubber cable port covers aren't of much use. They tend to fall off easily and you might find them rattling around in your case. I left them off.

One of the 4 mounting holes did not match my case, but I'm doing fine with the remaining 3 screws.

Other Thoughts: My goal was as near silence as I could get and I didn't want to take a chance on the coil whine often found on other well-known fanless brands.

As configured, I can't hear this PC at all from a distance of 4 feet

This PC can't use even 200 watts, so I didn't need a 500 watt PSU. However, the verification test shows this PSU to be over 91% efficient at 112 watts, which is a typical load for me.

5 out of 5 eggs2 year test of time

Pros: Just as advertised - silent
Has met all my power needs
No undue heat

Cons: After two years - none that I can see

Other Thoughts: I built my rig with the overall aim of having a silent system so all my components are selected that way. This power source was perfect

5 out of 5 eggstotally silent

Pros: totally silent, no problems with it, comes with just the right cables, seems to be a quality item

Cons: it's a bit pricey, but the silence is totally worth it for me. Not fully modular, but the nonmodular ones are stuff you'll want if you're looking at this (atx, cpu, and one pci). Interestingly, all the modular slots on this are 8 pins, whereas my prior Rosewell PSU had 6's and 8's. Works fine w/ the cables they include, tho!

Other Thoughts: this is the, wait, psu I'd been looking for. Made my system go from too loud to totally inaudible. Yay! I'm using a fractal R4 case, 4790k,noctua cooler, Asus strix 970. someone was smart about the cables to bundle, much appreciated.

3 out of 5 eggsnoisy

Pros: well built, small, and can hold a regular size cd player

Cons: extremely noisy,even without the stock 80 mm fan. I moved everything from a Silverstone sugo case to this case, because those slim cd players never work. There was almost no noise whatsoever in the sugo, but, this case sounds like a greyhound bus, comparatively speaking, of course. I removed the dust filters, it must be that the holes for the 120 mm radiator fan are not quite big enough. That is the only fan. To bad because I will have to resume my search for a small mini itx case that can hold a cd player. The sugo is big enough to hold a full size cd player, maybe they make it for a slim player because Silverstone sells the slim players.

5 out of 5 eggsThis is It!

Pros: No noise, None. Plenty of connectors, even legacy 4 pin.

Cons: A bit wider than typical power sources. Had to use more pressure than I thought I should to get it in. A minor issue.

Other Thoughts: Studio PC now dead quiet! Yippee!
