Power Supply recommendation?

[Z300M]

When I built my FreeNAS machine originally I reused an Antec NeoHE 550 PSU that was to hand. This predates the 80-Plus rating system but claims to be a High-Efficiency model.

i just measured the power consumption and saw a maximum of 0.9A @ 120V -- only 108W.

Would I see a significant power saving with something like an Antec EA-380D Green, which has an 80-PLUS Bronze rating?

I am using an Asus F1A75-V Pro mobo with five 2TB Seagate 7200rpm SATA drives, On-board video, so no power-hungry video card.

id be interested two, ive got a 300w evolab generic type psu. pull 49watts at idle, wondering what improvements id see going for a Be Quiet! BN133 SFX Power Supply (300 Watts) 80plus.

running atom d2700mub 4gb ram, 4x 3.5" 500gb hdd, pci sata card.

My guess is the NeoHE is up to 85% efficient based on the 380w model.

Dependson what you consider "significant". For the power you are using, even if you saw a 10% increase in efficient(virtually impossible) you're talking about saving 10w. I'd bet that over the next 5 years you might not even make your money back on the power supply.

I'd just stick with what you have until it fails. Then buy something more efficient.

anyone got any thoughts on this type of thing? i know you still need a mains to 12v

The PicoPSU versions of that claim to be around 96% efficient, but pretty sure that doesn't include the efficiency of the AC/DC adapter that is needed if you want to run off AC.

Normally the ratings, bronce, silver and so on, are mainly tested with 50% or above load. I've tested my previous Freenas setup with the 3 PSU's I had available and the differences with two of them are almost irrelevant. The PSU's are a Hiper Modular Type-R 580W , a LC Power LC6600GP 600W SilentGiant Green Power V2.3 and a TOOQ EP-500SP 500W ATX (nearly OEM). With the box was running with all harddrives turned on (11 3,5" WD Black HDD's and 3 Fujitsu SAS 10K HDD's) and without any datatransfer, the power consumption was arround 180W (220V), to be acurate for the Hiper-x PSU (178W) and for the LC-Power PSU (179W) but with the Tooq PSU the power consumption jumped to nearly 200W, 199W to be exact.
The TooQ PSU is available for 20€ ($25) in 2012, for the LC-Power I paid 55€ ($69) in 2009 and the Hiper-x set me back 120€ ($150) in 2005.

The conclusion drawn is that you will have to check the different PSU within the exact same powerdraw (108W for Z300M and 49W for fizzgig656) to se the power eficency of each one, but I can guess that if you use a PSU with a aceptable level of quality, the differences will be irrelevant.

Hi guys,

Take a look at this page:

The thing with power supplies is that it's actually pretty hard to make something really efficient at a low load.

I'm looking at
LC POWER model LC9550 V2.3 - Gold Series


http://www.lc-power.de/index.php?id=400&L=1

On a few reviews out there this thing wiped much more expensive "Platinum" efficiency PSU's... the only bad thing seem to be secondary capacitors brand... cheap Chinese... but regarding efficiency this is really best buy!
And the price is also very nice for "Gold" efficiency..

Seasonic SS-520GB

on the other hand seems better choice, thou they decided to cheap out this GB series PSU's... so it's not really great 'inside' as one would expect from such brand.

Nevertheless, you can't always get what you want...

LC POWER model LC9550 V2.3 - Gold Series

Hi, have you decided on it? Is it doing good?

I'm considering an LC Power case equipped with LC Power 300W SFX PSU purchase...

I don't know this particular model, but according to reviews the LC9550 seems quite ok.

Although I personally wouldn't use an LC Power any more.
I have witnessed 3 PSU deaths myself, and friends told me about when their PSUs died, all except the LC died silently and gracefully, the PC just went out and that was all about it.
But my LC died with a bright blue flash and a bang, fortunately it didn't kill any other components.
Their build quality may have drastically improved since then, but I can't get that image out of my head...

That was nearly 5 years ago...
