	Haven't dealt with them personally, but have heard good things from others. 86% 5-star reviews out of 107 isn't too shabby. I'd get it based on this review alone: "I design power supplies for a living. Getting a 550W off-line supply to run at 88% efficiency takes skill. This seems to be the real deal." ____________________

I haven't either but in looking at Newegg and around the Internet there seems to be a global consensus of kickassery associated with their products. Taking a look at price vs. performance...this seemed to be the best bang for the buck in terms of range for what I wanted out of a power supply to run this dual-core on top of the X1550 and whatever else I have in here. I don't think I really saw anything else, in terms of reviews, that could come close to comparing with this. ____________________

Okay...this is what I'm looking at before I take this apart: This 450W currently shows this on my 1.8GHz dual-core Pentium: Vcore1: 1.23V Vcore2: 1.63V +3.3V: 3.22V +5V: 4.95V +12V: 11.71V -12V: -7.18V -5V: -4.75V +5V: 4.81V Vbat: 3.28V I'm pretty sure those core voltages could be better too...but I'm gonna pull this old one and put a new processor (2.2GHz dual-core) in there and get back to you guys on the diff in speed and voltage soon. ____________________

Dual-core 2.2GHz w/ new 550W SeaSonic: Vcore1: 1.17V (-0.06V) Vcore2: 1.63V (+0V) +3.3V: 3.30V (+0.08) <-- dead on. +5V: 4.95V (+0V) +12V: 12.03V (+0.33) <-- almost dead on...now in tolerance. -12V: -7.18V (+0V) <-- mobo maybe? -5V: -4.75V (+0V) +5V: 4.78V (-.03V) <-- ??? Vbat: 3.25V (-.03V) Front panel displaying information about system temperature NOW works. The 450W old one is DEFINITELY not named since I have found no power supply emblem or anything of the sort on it past 'Made in China'. 2.2GHz up from 1.8GHz 2GB RAM replaced via OCZ from Kingston/Buffalo and of different speed (PC5400 from PC4200) 250GB Seagate SATA added. All in all...not bad for 40m worth of work...I still wonder what's up with my -12V though. ____________________

This is what I found on -12V: -12 V: This voltage is used on some types of serial port circuits, whose amplifier circuits require both -12V and +12V. It is not needed on some newer systems, and even on older ones not very much is used, because the serial ports require little power. Most power supplies provide it for compatibility with older hardware, but usually with a current limit of less than 1 A. So, unless you're actually using a serial port, it's nothing to be worried about. Same with -5v...I think only one of my ATX PSUs actually has a -5v line (it's in my arcade cabinet for that very reason). It's entirely possible that your motherboard is reporting fake or invalid values for the voltages it doesn't need/support, since they didn't change between the two PSUs. All the main voltages are spot-on (or close enough), and that's all that really matters. ____________________

	I'm thinking mobo issues...if you look, there's TWO +5V readings. I'm thinking anything -12V and below minus the bat is off...and even then I'm not too sure. ____________________

	Don't modern PSUs have two +5v lines, one for normal operation, and one for standby/sleep? Maybe that's it... ____________________

	Hmm...yea...for some reason SpeedFan shows it as +5V instead of +5VSB... ____________________

Okay, I can guarantee there's nothing wrong with your motherboard or new PSU...SpeedFan's giving me weird results, too: +3.3V: 0.00V -12V: -16.97V -5V: -8.78V It's also reporting +12V as 11.26V, even though the official Asus voltage utility that came with my board shows a very normal 12.11V. In fact, pretty much everything it's reporting is off by some amount, compared to other official/specialized tools. Maybe the program just sucks. I'd suggest trying out some official diagnostic tools for your motherboard to get more accurate figures. What model is it, anyway? ____________________
