Quality PSU?

lweddin1

Supermicro 2758 motherboard, I am looking for a quality PSU. The case I bought came with a 300-w psu that was garbage. Any suggestions? I have been reading posts say get platinum/gold….

heper

i've never had a garbage psu anywhere … what make it "suck' ?

only difference in psu's i've found is the efficiency (in other words loss when converting voltages)

kejianshi

Crap capacitors, crap solder, crap fans, too little heat sink, not enough amps available, unstable voltage… Lots of things can make a PSU suck.

Find one with LOTS of ratings and very few complaints. mini-itx form factor?

Cheap and few complaints:

This one is interesting because it seems to accept anything between very low and very high voltage without touching a switch....

You also have to read the ratings to see if people are whining about something you won't care about (-:

I consider fire/sparks a big deal, but sometimes people are fairly stupid and bring it on themselves. Not setting the voltage switch?

Whatever you pick, pay attention to the ATX connector. You need 24 pins.

Was browsing the site and felt the need to comment here. OP, do not ever buy a passive PFC PSU (the kind with a voltage switch). I don't know if there are even any passive PFC power supplies that actually have an 80 Plus rating due to how inefficient it is.

That being said, what case is this going in? Is this a server case, ATX PS supporting case, or a mini-ITX case? The biggest things to look at are the OEM who makes the powersupply (Seasonic and superflower are my favorites after delta, but they're all generally more expensive), the voltages on the rails, and reviews from power supply sites. I enjoy the jonnyguru reviews a lot, and they get in depth with ripple suppression and power spike testings. There are other great sites as well. Newegg and amazon reviews should be taken with a grain of salt unless they're well constructed and thought out.

seasonic or supermicro psu

You need to tell us what kind of case you bought since not all boxes use the same size PSU.

Also, which C2758 board? SuperMicro's Mini-ITX Avoton/Rangeley boards can be powered directly by DC. The uATX boards need an actual PSU for the AC->DC conversion.

This is the psu I am thinking about getting.

I currently don't have a case.

kejianshi

Looks nice and cheap with not alot of complaints… Still, need to make sure it fits your case.

I have this one in my pfsense 1U case: (Seasonic SS-250SU)

Works flawlessly, quite and do so running very cool.

This is my first Seasonic but not the last one.

Which Case did you get?

Micro ATX

I am thinking about getting this PSU…

No case right now, I returned it with the case I bought.

Unless your configuration is pulling > 20% of the load rating continuously, you will not see a big difference between high-efficiency versus regular power supplies. That said, my standard ATX/EPS form factor power supply is the SeaSonic SS-400FL2. It has two features that make it worth my money: The modular cable system and the quality of the components. It's also fanless and carries an 80 Plus Platinum rating, if that is your cup of tea.

I tend to use whichever PSU the vendor ships with rackmount cases. There are some notable exceptions, but most vendors include an appropriate PSU up to the task of continuous duty med-/high-load draw.

get something more along the lines of server grade. get a corsair if you want to cheap out

kejianshi

I don't know - I like cheap when there are very low numbers of failure reports.

543 ratings and 90% of the people using that like it. Cheap or not, its proven.

EA-380D is supposedly delta OEM, which is about the best OEM you can get. They're the ones who make power supplies for many company's servers. Never look at newegg or amazon reviews, half the people who get items don't review, just the ones that have "coil whine" and blame it on the PSU instead of the load that they're putting on their PS. Look at real reviews that use an oscilloscope the measure voltage regulation and ripple as loads change:

I normally prefer atleast gold efficiency for PSUs that go into machines running 24/7, but if you're going to keep it at a ridiculously low capacity (such as an atom cpu) it won't make much difference. Corsair has been moving towards lower quality channel well PSUs for their low end, they're not as good as they once were for cheap PSUs:

Edit: Didn't see this post, but it's correct.

That PSU is a bit pricey, but it's pretty amazing. I ended up cheaping out and getting the Seasonic SSR-360GP instead which is gold rating + a fan.

What's your budget?

Supoermicro have a nice case for that board, with 500W+ supply

I decided to call my local computer stores till I found a quality PSU. I ended up getting
http://www.newegg.com/Product/Product.aspx?Item=N82E16817153023&cm_re=tr2-430w--17-153-023--Product for $8.60 it was used but it tests out fine. I also picked up a computer case for $20. I decided I didn't care about the look right now. "Will post pictures later" I also bought two fans and now my system runs at 20.0 Degrees C it use to run around 55C.

kejianshi

Actually… Its not bad for the price. Price matters.

lweddin1

I am happy with this PSU over my last no name PSU. I am already noticing a huge difference. Random question, why I enter the BIOS config and turn on "Watchdog" why does my pfsense keep restarting after about 1 min after it boots up. If I turn off watchdog it runs fine.

Anyone have any reviews on this PSU? When you say price matters do you mean for $8 its an ok PSU? or overall its an ok PSU.

Pylor

I would not consider that a quality PSU, I wouldn't even use it. Passive PFC shows its age. I've looked for reviews on it but I can't find anything solid as it seems like they've changed the internals for the samme model since 2005 at least. The efficiency is going to be somewhere around 73% at best, and I have no idea what the ripple would look like.
