Need a little help in digging up a place to buy this psu.

I read a review of it (just came out today) here:

http://www.bigbruin.com/reviews05/epower550/index.php?file=1

The official name is E-Power Technology Silent Engine Tiger 550W PSU, with a model # of EP-550.

Googling either of those names, or froogling them comes up with absolutely nothing. Im pretty sure its a rebranded tagan, as most epowers are.

If you guys could find a US retailer for this, or the tagan its branched off from id really appreciate it.

It seems like an amazing psu

1) Tagan, so its quality
2) Modular
3) SLI ready
4) Two 20a 12v rails that are combinable


Feel free to comment on what you think of it too.
 
I know the "guilty until proven innocent" on psu's and i agree with it. Im not basing my decision of their tests, they were quite halfassed. Im basing my decision on the face that its Tagan, and Tagan's quality HAS been proven, time and time again. I believe this psu is the same as a tagan easycon. Epower is the brand name that tagan uses in the US.

Check into it please before you judge, its quality has been proven, so its not guilty

It's a Topower... and if anything, it looks quite a bit like the Modstream, which isn't that bad... just a little 5V-heavy in the OCZ lineup.
 
I guess i was wrong about tagan/topower/ocz/epower being good. They are all the same base, there goes my second choice too as it was an ocz.

Okay then, any recommendations. Here's what i want.

1) Modular
2) SLI Compliant with at least 32 amps on the +12
3) Reliable (no ultra crap)

1 and 2 together limits your options. What's your budget? What will it be powering?

This looks sexy but it's hella expensive: http://www.xoxide.com/sintek-600-sli-power-supply.html

I've heard decent things about this one: http://www.xoxide.com/hiper-power-supply-black.html

As a general rule Topower makes good units...why do you say they don't?
 
You see, that was my opinion as well, then the one i posted (which best i can tell is a tagan (aka topower) got bashed horribly, im not extrememly knowledable in the area of PSUs but i know an ultra from a fortran.

As for my budget, im looking to keep it under $130 US. Itll be powering an opteron 152, a 6800gt sli array, 2 gigs of ram, and 4 HDs (plus various other stuff, aud2, physx card when they come out in pci-e)


Edit: I was looking into the hiper, it looks real nice, but it doesnt have two dedicated pci-e cables, it uses an 2molex > 6pin adapter for the second pci-e

As for the Sintek, it looks decent, but "guilty until proven innocent" applies as they apparently are a new brand, and not a rebrand of something else

Generally Topower are good units. I do believe unless Dave has some info up his sleeve he was unneccesarily harsh on the unit. Dave?

_Korruption_ could very well be right. Without better pictures though I can't tell.

Allied is the devil! Well they were Deers the last couple I knew about anyway.

The Antec NeoPower 480W has a combined +12V@32A.

The new Sunbeamtech 550W is the only SLI Certified modular:
http://www.extremeoverclocking.com/reviews/cases/Sunbeamtech_NUUO_550W_1.html

Topower makes several lines of PSU's from OCZ, Tagan, down to the "free with $19 case" class.

Dave
 
The Epower is still Topower built - not sure if it's a new design or not.

Actually I kind of like the looks of that Sunbeam (Andyson OEM) - they look well made.

Not sure about ArrowMax, but Allied is Deer made. Stay far away from them - I have yet to see a PSU company make worse units than Deer. They fail often, many times taking other hardware along for the ride.
 
The mobo is the Nforce pro based Foxconn NF4PIK8AA-8EKRS. Only decent opteron board out there really (single socket).

http://www.newegg.com/Product/Product.asp?Item=N82E16813186055 <--thats the mobo

I actually am ordering it tonight or tommorow, i dont have it in my possesion yet, im typing this on a 9800pro and a sk8n right now.

I have my 6800GTs and my 152 sitting here waiting for me to order the mobo, and find a good psu to go with it, i thought this one might be it, if i could find a place to buy it
 
@ davidhammock200

thanks for the recommendations, ive looking into both of em. The neopower definately has the rails, but id have to use a molex > 6pin adapter.

The same problem applies with the sunbeam, it doesnt have two dedicated pci-e plugs, it uses an adapter for the second one.

Maybe its just me being picky, but id rather stay away from adapters, they seem kinda messy to me, besides, its nice having emi shielded cables, which most dedicated dual pci-e adapters are

Edit: also, im not all that particular about it being Nvidia SLI Certified officially, as they are very selective. If its a reliable brand and fits my qualifications, im ok with it not being officially certified

Unbelieveable! :eek:

You would buy the unknown, untested PSU in post #1 because it has nice cables,
but refuse to buy good, proven, even SLI Certified PSU's because you don't like the cables! :rolleyes:
 
Apparently you dont share my opinion of topower based psu's, you have every right to do so, but if OCZ or another reliable brand (which i think topower/tagan is) released a new psu that had some good features and fit your needs, wouldnt you be willing to take a slight risk on it, since their previous psus were good quality?

Agreed, and this appears to be tagan based (a direct port of the tagan easycon) which is only available in europe it seems. Not the 19buck ones
 
and if it eases your scepticism any. Heres a direct quote from johnyGURU on the easycon and epower.

Haven't seen it in the states yet.

One thing: You know that it's probably the same as a Modstream, right? (based on same Topower platform.)

That said, keep your eyes peeled for ePower and/or PCMCIS. They're the U.S. importer and distributor for all things Tagan.

Since I'm not seeing the TG530 on their website here in the states, I'm going to say it's currently N/A.

Thats from http://www.hardforum.com/showpost.php?p=1028177580&postcount=8


And yet another edit: ffs, you said the psu looked good yourself :)

davidhammock200

Brand new, made by Topower & people from UK & UE like them.
Should be a very good PSU.
I haven't seen any in the US yet either.

Oh.. Hey.. I actually have one of those sitting right here.

It's based on the Topower P5.

The "guts" look small in that photo at Big Bruin because the housing is actually a bit oversized. Not as big as a Powerstream 520ADJ, but bigger than a Modstream.

I would have a review up about it, but mine keeps tripping (like it's on acid?!?!) As soon as I put a load on anything other than the +5VSB, it stops running after a couple seconds.

I put an email out to Topower/ePower. Hopefully they'll get back with me. Im sure I just have a bad unit. God knows that happens every once in a while. :D
 
Well then, the god has spoken. I dont suppose you would know where to purchase one (as i assume you got yours straight from epower). Im willing to be a guinee pig for this psu

Look... Don't EVER call me the God of ANYTHING except for of my own abode, ok?

(Nothing personal, it's just easy to touch nerves with me.)

Usual outlets for Topower/ePower/PCMCIS is Newegg/ChiefValue, MA-Labs/eWiz, TigerDirect, MicroCenter, and Fry's/Outpost.
 
Okay, my apologies. No religious tone was intended. Let me rephrase "the guru has spoken"

Feel free to ban me from hardforum if you wish, or have a mod do it.

:p Yeah right. ;)

Call these guys: 1 (909) 869-6188

Census PCs. They have more Topower/ePower/PCMCIS/Tagan/whatever-the-hell-you-want-to-call-them then ANYONE else I've seen. If you want one bad, I'm sure they can get one right away.
 
I shall call them tommorow, thanks for the advice. I really appreciate it

Thanks to all of you for your comments, if i do manage to get this psu, ill be sure to post my impressions of it
 
And it has nothing to do with religion...

I deal with "know-it-alls" all day. "God's in their own eyes." The last thing I want is someone grouped in with them. In my years I've learned that you can never know everything and as soon as someone opens their mouth stating so called facts about something they no nothing about, everything that person says is discounted as ignorant babble.

Read my rants sometime when you get a chance. You'll need about an hour and a cup of Joe. ;)

It took me 3hrs & a bottle of scotch! ;)
 
Sadly, they dont have, nor have even heard of it. I sent them a product link and they said its not in production yet. (which apparently isnt true since you have one jonnyGURU :) )
 
Might want to hold off on this one...

Here's my prelim findings.....

+5VSB @ 2.5A

EFF = 51% PF = .51

0 LOAD

EFF = 64% PF = .50

+3.3V = 8A, +5V = 10A, 12V1 = 10A, 12V2 = 10A (334.5W)

+3.3V = 3.36V, +5V = 5.11V, 12V1 = 11.9V, 12V2 = 11.88V EFF = 77% PF = .70

+3.3V = 8A, +5V = 10A, 12V1 = 14A, 12V2 = 14A (422.6W)

+3.3V = 3.35V, +5V = 5.14V, 12V1 = 11.62V, 12V2 = 11.61V EFF = 74% PF = .73

+3.3V = 8A, +5V = 12A, 12V1 = 14A, 12V2 = 14A (432.8W)

+3.3V = 3.35V, +5V = 5.12V, 12V1 = 11.64V, 12V2 = 11.63V EFF = 74% PF = .72

+3.3V = 8A, +5V = 12A, 12V1 = 17.5A, 12V2 = 17.5A (504.3W)

+3.3V = 3.33V, +5V = 5.16V, 12V1 = 11.33V, 12V2 = 11.32V EFF = 70% PF = .74

+3.3V = 12A, +5V = 14A, 12V1 = 17.5A, 12V2 = 17.5A (531.9W)

+3.3V = 3.31V, +5V = 5.11V, 12V1 = 11.44V, 12V2 = 11.42V EFF = 69% PF = .75

HIGH 5V

+3.3V = 10A, +5V = 35A, 12V1 = 8A, 12V2 = 8A (422.8W)

+3.3V = 3.31V, +5V = 4.83V, 12V1 = 12.59V, 12V2 = 12.56V EFF = 73% PF = .73

LOW 5V

+3.3V = 3A, +5V = 3A, 12V1 = 14A, 12V2 = 14A (360.5W)

+3.3V = 3.37V, +5V = 5.26V, 12V1 = 11.29V, 12V2 = 11.28V EFF = 75% PF = .72

Never mind the spiking 12V in the HIGH 5 test. That just a crossload and we've seen plenty of excellent power supplies respond like that.

Look at the first 5 variable load tests. Those 12V rails are fluctuating WAY too much for my liking.
 
Those results aren't too encouraging - the 12v readings at 504w look downright ugly to me. Overloaded at anything past 14A+14A it looks like, and even then the reading is still low.
 
Right! But the rails are rated at 20A/20A with a combined of 35.

Just look at the difference between LOW 5, back up to TEST 2 (12V load didn't change, yet the V's did drastically!), and then work your way down. Those reading are all over the damn place!

While the load was on steady, the rails were very stable (in other words, when there was a steady load on a rail for 30 minutes, it wouldn't fluctuate at all) but whenever the load changed, the voltage would bounce around like a ping pong ball until I quit hitting the UP and DOWN buttons!!! :eek:
 
Thanks for the results JonnyGURU, since i couldnt find it anyway i ended up ordering a Sunbeam Nuuo 550 (sli certified, had solid rails in the couple reviews i read). I know its got a horrible effieciency rating, but im willing to deal with that if the power is clean and solid

Interesting indeed. Did you test it with the two 12's combined? I wonder if there isn't some kind of design flaw here, or perhaps something as simple as a dirty switch or poor soldering under the PCB.

It's very clear these aren't P6 based already though ;)
 
question is as far as AMPs and dual 12v rails etc.. i dont know about it and real question is hows the power supply my brother has in his system thermaltake purepower 420

amd 2800+
3x 512 ddr pc3200
40gig Hd
17"Dell monitor
HP dvd DL R+/Rw+ and -
ati Raedon x850xt
Thermaltake 420 purepower

is there a sticky for all the tech info on 12v dual rails, amp readings etc...?
