Need new PSU

[4-n-zics]

The Emermax Liberty 500 watt PSU I had running my spare rig just up and quit the other day. It might have been cause by a sudden power outage while the computer was running, but it could have been something else. The CPU HS fan spins up for a second and then quits. There are several recent threads with the same problem and I had the same problem a few months ago with a different spare rig. The Enermax PSU had 22 amps on each of the 2 +12volt rails and was only running an Opty 165 stock, 6800GS stock and 2 * 250GB HDDs in RAID 1 so nothing special or hard core.

I was reading through several threads asking about PSUs and found this PSU listed:

http://www.newegg.com/Product/Produc...82E16817139008

It has 30 amps on the +12 volt rail (single). Would the be sufficient to run the rig listed completely stock. I am trying to find something that is very inexpensive, but is still of a good quality.

I did try to get an RMA for the PSU, but was denied for being out of the 3 year warranty.

definately, I got my rig (sig) powered by a dual rail seasonic 430w that has 14A and 15A on its rails...

I bet this one will also do the job for you: http://www.newegg.com/Product/Produc...82E16817151077

even this one has 17A on each of its rails according to newegg specs but that sounds kinda much for a 300W psu: http://www.newegg.com/Product/Produc...82E16817151059

ok 17A sounds good for your specs but 300W sounds like too little for a pc with a graphics card that can consume up to 55W

that corair will do you well I'd say esp if you get the rebate.
There are some refurb OCZ ones I posted about a few posts down and david seemed to not have problems with that were VERY well priced on svc.com

Yes that Corsair 400W will be fine & you will be happy to know that they are quite under-rated as well.


Best Wishes,
Dave

We checked the specs on one model & it was rated at 20C, so it would really only give you about 50% of its power rating in a real computer case, where as that Corsair is rated at a minimum of 40C.

hey dave do you think those seasonics I posted will also do ok with that system at stock? just curious. and they are cheaper too

No, we never want to go below +12V@30A with a mid-range GPU.

so you're saying my system in my sig is actually a bit underpowered with the 430W seasonic, 12V1@14A 12V2@15A ?

I never mentioned your PSU.

If you provide a link to your exact PSU, I will be happy to look for you.

OP, yeah the 400CX will do just fine.

Using 3 of those bad boys, one in a friend's i5 750 undervolted with turbo on and a bunch of hard drives (5 to be exact) and a 9400GT, another one in my friend's 7750BE @3GHz, 8800GT (and right now 6 hard drives) + a bunch of fans, and a last one on my 754 rig (DFI or ASRock board, OCed CPU, 6800GT).

Theyre silent and well made. Not like the usual Corsair PSUs tho, but the rugged look has its own style. Plenty of long cable and it's all sleeved up!

Thanks guys.. got the Corsair on the way. The $20 MIR makes the deal even better.

And unlike OCZ, Corsair actually pays!

CONGRATS!

SO TRUE! OCZ rebates are a JOKE!

congrats on the PSU, I love my corsairs, i run one in each of my i7s.

True that.. I never received my rebate from OCZ for the 16GB Diesel USB Flash drive.

Yeah, I have the 850TX running in my i7 build. Sadly, I have yet to overclock this rig.

[davidhammock200]

It is very strange, OCZ PWNS customer service, but they p*ss off everyone with their no-rebate rebates.

I wonder why?

Got mine after.... hmm, I cant remember. Something like 3-4 months, if not more.

here you go http://www.silentpcreview.com/article226-page1.html

I assumed as you said a medium ranged pc should not get a PSU with less than 12V@30A, and the ones I linked had 17A on each rail, and you suggested against it, and mine has even less than 17A on each rail...

You have a Max Combined of only +12V@29A, so yes you are a little light, but what is an amp or 2 between friends.

The per rail current limit isn't very important, it is the total available +12V amperage we are concerned with, "Maximum Combined".

If you look at the sticker on the side of your PSU, it list 348-watts for the +12V rails. 348 divided by 12 = 29,
so you have a Max Combined of +12V@29A, but it is a Seasonic, one of the best PSU's available & I don't think your system is too demanding, however if buying new I would recommend a Corsair 520HX or 550W with +12V@40A, so you would have more headroom for OC'ing & transient response. Or a similar unit from Antec, BFG, Enermax, PC P&C or Zippy.

ok, good to know however my future plans are to go with laptop only...

I just looked up the specs for that 350W seasonic, it has 17A on each of its rails but a combined 12V power of 324W, that's 27A total (something doesn't quite add up here). So that one should also still be on the border of being ok for 4nzics system.

We don't ever recommend "on the boarder" or "it might work" or "get by with", we always give good conservative recommendations for products that we "know" will get the job done!

I guarantee that the Seasonic 350W will work, but it will run hotter,
make more noise & will always be a question when ever a problem comes up.

We want to load the PSU to 40% to 60% of its rated capacity, not to exceed 70% for continuous operation, as this gives us the overhead necessary for cool, quiet operation and transient responses. In addition to myself, you will find Paul@[H], both Jonny & Wolf@JG & every other PSU guru are in general agreement.

ok gotcha thx for the info
