If you were to get a multimeter or occiliscope and 1) found they were fluctuating as much as you think 2) they stabalise afterwards then by all means laugh away. :)

I'm going to bed in hopes that galvanized finds this thread. when I get up this afternoon I'll grab my voltmeter out of the garage just to get you to eat crow :p

By all means!

"High end power supply search"...That needs definition. To some it means totally pimped out and over-rated output. These units are like uber-blinged skateboards with the wheels ready to fall off. ;) I have not used a skateboard in 35+years :laugh:

Our resident PCP&C Rep.is correct in saying thier units are VG but at a price to cover marketing & customer support. I have no use for marketing=bragging rights or customer support. The 850W they offer is very good indeed however.
(Bragging rights: Never had the need for a Harley. I toured on BMW and Moto Guzzi ;) )

BTL is very correct in pushing low wattage PSUs, if the unit is of very good quality. Lite-On builds for Dell and this is why guys can get away with using 7800s in thier machines that have 350W PSUs. Not all Dell PSUs are Lite-On provided however, afaik.
My concern would be some youngster thinking his L&C or Young Year provided 350W is up to the task a Lite-On provided or Zippy/Emacs 350W *IS*. Both these latter units would crush a cheap 500W PSU.

Home PSUs=Consumer are one ball park. Server/Desktop is another. The latter will generally have more powerful 80mm fans. This is a major turn-off to most, so units with 120mm fans are considered by most and these will generally fall in consumer class. There are many VG PSUs in this class. Seasonic, Enhance, Enermax, FSP Epsilon...It's a long list.

OP, I PMed you a thread to read. Be aware, the 0060 is 185mm deep. The face is 150x86mm however. The fan is thermally controlled but will ramp-up under 50% load,iirc. If I were to use this unit, two Sanyo Denki 80x25mm@40cfm@30dBA would be used. There is an empty fan port at the front of this unit. Both fans would be hooked to the primary fans wiring. This would give a good push-pull for air flow with decent dBA.

I have two Zippys in use. Both were modded for external 92mm fans @48cfm. An 80mm@25cfm was bonded to the far side of the intake grill. This keeps the thermistor cool that controlls voltage to the primary fan. Works sweet. My units? HG2-6400P, 400W, 12V@30A...HP2-6460P, 460W, 5V@40A(way too much), 12V@28~32A. The latter is a real server PSU and can carry 12V@32A for 17seconds once a minuet. Why?? Boot & accessing HDDs. It's a shame it only supports 4HDDs.

Zippy/Emacs is the only SMPS builder I know of that shows all certs in pdf on the right of any selected PSU. http://www.zippyusa.com/ Take a look "for fun & free".
A recent review of big brother http://www.overclockers.com/articles1313/
http://www.madshrimps.be/ >articles>PSUs>Mega PSU test. Read, note what Edward Chang has to say.
http://www.buildtoorderservers.com/ Has the PSM 6600P for $199=very good deal. 12V1@26A, 12V2@20A, combined=40A.

http://www.myaopen.com & http://www.servercase.com/ both carry Zippy/Emacs

http://www.jonnyguru.com/PSUInquisitor Trust reviews from SPCR, XbitLabs & Systemcooling. jonny's reviews are good but he has not had any server class PSUs in-hand, iirc.

Silverstones Zeus series is VG but took a black-eye for cross loading problems. Etasis builds these for s/s and is to be considered an upper tier design/build. I think this problem has been addressed. If I were to get one of the older units, that needed a decent 5V load to permit the 12V line to have it's full potential, a ballast would be used in the 5V line to kill 5A and installed at the case exhaust for cooling.
To understand why this would need to be done, you must have a basic understanding of how a single transformer supplies all three voltages for a SMPS.

I just bought an Enhance EPS-0560G, 600W, quad(silly)rail, 12V combined@42A,peak 45A. Efficiency at 230W is a low 69% but at 330W it jumps to 77%. Why do I think I need this?? Next Winter my heated motorcycle riding gear will be put to good use on one 12V rail :p My fort/office is unheated and a space heat uses far too much wattage, plus it's a fire hazard ;)
Just like the 510 Turbo, it has ports for adjusting all three lines w/the cover on. The 0560G will Froogle for $110. I got mine for $99.

I dislike PSU pissing contests but will respond here to any PM or via PM. I make no claim to being expert on SMPS or any other hardware. There are some very sharp members here that avoid PSU threads and I may join them when I get smart=may never happen.

Note: The Epsilon does not have independent line regulation, so agjusting each rail is out of the question. This is NOT a bad thing but should be noted.

Good luck on whatever you do with your money. It's all your call. Hope I put a little light on the subject at hand.

BTW are you measuring your Seasonic's voltages with a multimeter?

Oh you're using software.

Ok, before you even complain about Seasonic, measure the voltages with a good meter. Trust me, software is WAYyyyyyyyyy off. I'm told my 12v rail is like 11.89, but I've measured it to be 11.98/11.99 with a meter. Same with the 5V rail. MBM reads 4.94, but a meter tells me 5.01.

Stick with your Seasonic. Your system is FINE. You don't need more than that. 18A per rail is PLENTY.

Look at my system. 3700+ @ 2.66, 7800GT, Seagate 7200.8, Hitachi 7K250, DVD RW, CDRW, USB 2.0 card reader + floppy, 3x 120mm fans, VF700 cooler, Iceberq 4 chipset cooler, I have a buttload of fans running in there.

Oh and a little before I was running dual 7800GTs.

Don't even worry.

Idle:

ITE SmartGuardian: 5v @ 4.89, 12v @ 11.58

Multimeter: 5v@ 4.76, 12v @ 11.63

ITE doesn't do a half bad job, huh, I wouldn't have guessed.

yes, I realize these are both right about 5% off and that is not bad by any means but, I'm going to blame the PSU for me not making 3ghz till I replace it and am proven wrong.

BTW: thank you glavanized, yoda and bob for your input. Don't take my stubornness as fanboyism or me just being a prick, I just enjoy playing devils advocate a bit more than I should. i like threads like these, just to see what some people can come up with.

Well, it'll be interesting to watch at the least. Feel free to drop me a mocking PM if the new PSU does help you break 3.0Ghz :)

my software says 11.79 volts on my 12v rail of my Antec truepowerII PSU. I got curious, borrowed a DMM, lo and behold the voltages were right where they should be - I measured 12.02 volts with the DMM. The software would show a fluctuation up to 11.86 or 11.9, the DMM remained unchanged. Much more accurate!

Something is weird with mobo sensors for some reason, I don't know why they can't get them right. At least yours are better than most.

Board/chip heat + going through software/firmware. Maybe.

spanky, what 12v rail did you measure? if you have more than one 12v rail it's hard to say wich the software is monitoring. As my power supply has a pair of them i would have had no idea but, it seems that the software monitors the rail that goes through the motherboard and one line of accessory cables, the other line of accessories, the SATA conectors and the PCI-E are on another rail, I ended up testing every line off the psu including the 24 and four pin motherboard coneectors to see just what lines were connected and were running at what voltages.

it may be three weeks before I get a new psu as I got an offer from a guy at work to install a remote start system on my car for $300 total, and in an arizona summer, they are REALLY nice to have to that'll be my spending money gone will the next paycheck.

Single 12V wire on the ATX connector, traces in board, chip heat, load of everything else using that lead (fan headers, slot power, etc.) ITE chip, etc... Just like voltage that goes through a CPU VR is only 95% efficient coming out as it was coming in, same is true with voltage measured by a chip located half way across the PCB from the ATX connector. The margin of error is pretty great. And if they calibrate the chip to compensate for the resistnace, they're only going to throw off reading exponentially on either side of the spectrum. It's a losing battle no matter what. ;)

And you had said something earlier about tri-rail being one rail per PCI-e. I want to clarify that for you: A tri-rail gives one rail just for PCI-e. So it's like a regular dual-rail, but with a third for both PCI-e connectors. And not all quad-rails are two rails for two PCI-e's. In fact, they're typically two PCI-e's on the same rail, or a second PCI-e on the rail with CPU-2 (since dual CPU systems rarely also support SLI.)

My Seasonic S-12 600w will power my machine if necessary:
dual Xeon 2.66 GHz
2GB RAM
6800GT OC
6x250gb SATA hds
2x160gb SATA hds
8-port RAID controller

It kinda starts to hiccup when I start putting on the 12 fans.
I don't always run my system like that though. I normally have the 600w powering the mobo & video, and the 500w Seasonic powering the fans, hds, and lights.

I'd say your alright with that 600w Seasonic.
