"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.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

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.
