This PSU is 140mm deep. Do you have room for a 185mm deep unit?? Why do you want/need an uber-single 12V rail?? I don't HAVE to know, just interested.

I'll be back later.

Well, it's a good power supply and that's the most important point I want to make here. My only question is this part of the spec...

Hold-up Time 17ms min.

The OCZ 520 watt PowerStream is tested at 50 C and the specs given are constant duty specs and no micro, or even milliseconds allowed! The OCZ is priced about the same...

http://www.newegg.com/Product/Product.asp?Item=N82E16817711002

Here's the specs on the PowerStream...

http://www.ocztechnology.com/products/p...cz_powerstream_power_supply-sli_ready_

Remember, there's a $25.00 rebate at newegg now on the PowerStream models. Stay away from the ModStreams because they are not nearly as good.

While I have no direct experience with the Enermax model, I own a 520 watt PowerStream and it is quiet as a mouse and stout as Galvanized's breathe! ;) It has a 5 year warranty and OCZ's rMA department is legendary for fast, reliable service if ever needed.

So in the end, they're probably about the same as far as delivered power and maybe the OCZ PowerStream might be quieter... I dunnow for sure and it may deliver steadier power, but all these things are slight. It's up to you in the end and either purchase would be a good power supply.

I am looking to overclock P Ds. Hmm, I have multiple full tower cases, I believe deepth won't be an issue. Also I am running a swiftech mcp-655 and two highspeed panaflos for the rad and also will run a x1900xt. I hear higher single rail is better for p d overclocking.

I currently have an Antec TPII 550 dual rail 19A on each. It runs fine, but seems to run hot. This psu seems like a good deal at the price its going. I was looking to buy the pc power and cooling 510W but this is half the price. :) Which is why the exploration. Thanks for your reply galvanizedyankee and Luckyboy1.

One other thing - my P5WD2 premium has a 8pin connection in it. Right now I am connecting the 4 pin p4 connection in it.

I see that the Enermax one has the 8pin connection. OCZ pictures at newegg does not show the 8pin connection. Do you guys know if it has it? Does it really matter having it or not? I thought its an EPS thing.

That linked unit is probably good but it is dated stock. Here's what Dan's DATA has to say.
http://www.dansdata.com/eg651p.htm here's an overall VG resource http://www.jonnyguru.com/PSUInquisitor

http://www.buildtoorderservers.com/ Has the Zippy/Emacs PSM 6600P for $199 and you won't
find a better PSU 12V@40A. It is dual rail but 12V1 will offer 39A. It's 160mm deep.

If you can fit 185mm deep. SuperMicro PWS-0060 Froogles at <$120 and offers a single 12V
rail @ 46A :Q The main harness is 16AWG. The OEM for this monster is LiteOn, a respected builder of SMPSs. They also build for ABLECOM.
The 0060 might need a little wiring rework to fit your needs. It has one 80mm fan but has a port at the
front for another 80mm. If I were to use this unit at 70% output both fans would be Sanyo Denki
80x25, 40cfm@30dBA. I found some for $10 and need to buy several, a very good pair of fans for this PSU.

All your call OP.

Galvanized, thanks again for taking the time to help me out. The dan's data review seems like is for the older version which has only 24A on the 12v rail but has higher on the 5v and 3.3v.

The SuperMicro PWS-0060 seems like a nice buy with 46Amps. Holy cow. Thats a hell lot of power. I am assuming when you say 185MM deep, you mean its longer than usual psus but has the same width. Then it should fit my cases just fine. I found the SuperMicro PWS-0060 at ecost for $124. Seems like a nice price. But then again the extra fan part. I do have some nice mascool 80mm fans lying around which I can probably use. The mascools move fairly good amount of air also.

As you can tell, I am also being a little cheap and staying away from Above $150 psus at the moment.

If you're looking for a quieter, more efficient solution, try the Fortron Epsilon FX600-GLN (on ewiz.com). Reliability may not be as good as Zippy or Liteon (desktop vs server), but is still good in its own right.

Howard, thanks for the post. I was also thinking about the fx600-GLN or even the fx700-GLN(when ewiz was selling it at a lower price). However, I am concerned that the 15A or 12V rails even though there are 4 of them might not provide enough juice for an overclocked Pentium D. I did see claims that FX700-GLN holds up just fine with P D and crossfire.

Finally, thanks a lot guys for the help. I believe I will begin searching for a good deal on the Supermicro PWS-0060. That seems like what I need (plus the pci-e and sata connector adapters) :)

The rails can do 18A.

VG unit but not very efficient http://www.ewiz.com/detail.php?name=PS-SP550SL
pdf for the above http://www.sparklepower.com/pdf/FSP550PLG-SLI.pdf

I just bought an Enhance ENS-0560G from eWiz for $99. None left but it will Froogle at $110.
Specs are at http://www.enhanceusa.com/ It IS the Silverstone 600W Strider specs
here http://www.silverstonetek.com/ This unit got rave reviews at jonnyguru.com and
systemcooling.com and XbitLabs.com(iirc)

For some detailed reading on the SuperMicro PWS 0060 go to http://www.badcaps.net/ > PSU Forum
Register there and talk to the fella that posted this unit. Very decent guy.
I would stongly recomend you do this, as info on-line about the 0060 is scant at best.

I think eWiz still has some 0555 Enhance units for cheap. 12V rails can be combined ;)
Just have to use an adapter.

A please :Q ;)

The quick, cheap&dirty way. Use and 8pin to 4pin adapter=done, for combining two of
the 4 rails. My way would mean posting pics at badcaps.net, taking the advice of some
very knowledgeable techs, then soldering internally. Warrenty-smorenty, fusk the Gar-oon-tee :p Bear in mind, i had no compunction what so ever about hard modding a 92mm
fan to the Zippy/Emacs running here. The restrictive grill was cut out before the adapter
was installed.

For a brief time, in my early 20s, I managed a tire store. We sold crap tires with a lifetime
warrenty :laugh: Yep, sure as hell did. In two years time they were prolly used to sole
Mexican sandals :p

I can't find it but did read the JEDEC spec. Desktop=5year, server/workstation=10year.
That is what they want, what is provided may be a different story ;)
If I happen on that spec, I'll PM it to you but if you happen on it let me have it. Plz.

Ofcourse dual rail is better than one. But for Pentium D high amparage on single rail is preferable due to it being a power hungry chip. I know next you will tell me to buy amd. I have used 5 opterons and 4 A64s. So ....

Thanks guys for the info. I appreciate it.

I was just reading the specs of Sparkle FSP550-PLG-SLI. People keep saying low efficiency. For me it doesnt matter much in terms of efficiency as I dont run my pc 24/7 and barely run it overnight. With all the stuff I am running and plan to run, I guess my psu anyway would be using upto 70% of its capacity - rough layman's estimate. So I am seriously considering it over the supermicro psu right now. 36A on a single rail should be plenty.

Galvanized, truthfully I clicked through and read every thing you and luckyboy1 and howard posted. :) Thanks a lot for your help. So Any final work on the Sparkle FSP550-PLG-SLI apart from low efficiency? I do see that they test their psu at 25degrees.

If I had the room and it was my build, I'd opt for the 0060. But first I'd talk to tiresias
over at badcaps about it. He bought one 6 weeks ago. He has a Power fetish. He is very bright dude, lives in The Netherlands. iirc, the fan in the 0060 is a Sanyo Denki. Splicing a second fan into the primary fans circuit will keep it quiet. I think it's 70+% efficient and rated at 40~50C. You'll have to ask him. He does post everyother day so you'll get a quick answer to all your question. Just present them well. That Sparkle is a poor man's power house. It's just OK, that's all, no more.

If you look at other SuperMicro PSUs, just make sure they are not 5V line dedicated and 12V starved. Many server PSUs are like that.

tiresias' post is on the first page of the PSU forum.

Actually, that is completely false (the single rail being preferable, not the the Pentium D being high amperage.)

ATX12V spec puts the CPU on it's own rail. Typically, this rail is capapable of 16 to 20A. Twice what your Pentium D requires.

Where dual 12V rails comes into question is when you have multiple video cards (SLI or Crossfire, take your pick) and either both cards are on 12V1 and they're robbed of power because of all of the other devices on 12V1 (HDD, CDROM, fans, lights, etc.) or both cards are on 12V2 taking away from the CPU.

But if you're using one PCI-e card, you're perfectly fine with a dual 12V rail power supply.

If you're running SLI with a Pentium D, I suggest a tri or quad-rail that puts the PCI-e on it's own dedicated rail.

The concept of less VA going through a single regulator is still ultimately the best practive. It's suggested by both Intel and the UL for a reason. ;)

Yahooo!! Now I managed to draw attention of all the PSU gurus at AT.

Thanks JonnyGuru and others who I thanked earlier.

This clears out my confusion. So according to Jonhyguru if I stay with the Antec TPII 550 with a single video card I am not taxing it. The reason why I was concerned it because both my Antec TPII and Antec Neopower blows fairly hot air when the pc is running at full load. On the other hand my dual rail fortron 450W is running real cool under the same set up.

I posted on badcaps in hopes to get more info about the Supermicro PWS-0060. I will most likely buy it anyway since single rail is fine for my setup - according to the explanations above.

BTW, JonnyGuru - your reviews of PSUs are absolutely fun to read. I wouldnt have read through a complete review of psu if it wasn't as funny.
