Modular Power Supplies

IMO in comparsion to an Antec Neo Power
thats a peice of junk

just an opinion
hard to say definatively, since there are no real specs published by Ultra
and Ive seen no "real" reviews of it

but a simple peek under the hood of those 2 supplies tells the story

neopower has a much more robust set of components
and real specs,independently verified (by someone actually qualified and equiped to review a PSU)

That thing looks pretty but i'd like to see some benches. I've already got a modular power supply, though that did me no good...i use nearly every connection--my case is wire hell!
 
thats a rudimentary review actually, but better than nothing I guess
considering all he had was a multimeter, however his test proceedure lacks quite a bit
for instance its pretty much a static load, a high one but a constant draw from folding
guess he thought that was a "stress" test

what you really want to see is a dynamic load and log it to see how well the PSU maintains the rails when spinning up and down drives, and going from full load to idle and back with the CPU & GPU (bold below)

ideally you also alter the AC input and see how it deals with that as well
and measure the noise on the rails (PARD)

a much better review rig > http://www.silentpcreview.com/section4.html

here are some logged graphs
http://terasan.okiraku-pc.net/dengen/tester/index.html
http://terasan.okiraku-pc.net/dengen/tester2/index.html

those are logged Digital Multimeter readouts off a Sanwa PC510 (0.08% accuracy) via RS232C or USB port to PC Link the logging software you see there
logging the +12V rail (and most are actually in spec

the test system is a Tyan Tiger 133 (S1834D).w\ Dual P3 650s overclocked to 865MHz (I think :p )
Dual sticks of 128MB PC133, a Matrox G400SH, Xwave 6000 sound card, NIC and a single HDD, FDD and CDROM
measured from startup, booting into Windows 2000, and Running 3DMark 2000 to conclusion, measured in 5 second intervals, which is definately less than ideal, but the best he could manage

not exactly a power hungry system that would be "pushing" those supplies too hard
I use those as illustrative of the instability that spinning up drives can produce (startup in almost all the supplies) and that was before the CPU and GPU where drawing the majority of their power off the +12V rail
those supplies are hardly at the edge of their capacity, nor are they dealing with less than ideal AC power
Ripple & Noise, not being specifically addressed.
and while they arent "out of spec" they arent being taxed either

there are only a handful of people that make a PSU review worth a damn ;)
 
So Ice Czar, what's your top recommended PSU right now besides the PCPower?

Is the NeoPower up there?
 
In theory yes, in that its a powerful stable and fully compliant ATX12V v2.0 PSU
that is also backwards compatible to ATX12V v1.3 connections and forward to PCI Express video

Well, yeah, that's really what I meant to say. I think by extensive I meant "several pages." Hee!

At least it wasn't the typical it-works-and-it-looks-cool-too" type of "review" that I'm used to seeing. Not being a PSU or electronics wiz, I'd go with the Antec Neopower regardless, mostly because of the manufacturer's reputation. I've never even heard of UPC before, and it doesn't seem like many others have either. I like risks, but not that kind. :)
