Okay, it's a power supply. Not much excitement there unless it starts smoking, right? But if you can't work up excitement, how about some respect? Like the 41 Ampere +12V rail (and there's just the one +12V rail, so you don't have to balance your power needs by hand.). How about the ability to auto-sense your input voltage from 90Vac to 264Vac, 50/60Hz? No more damaging your supply because the voltage selector was in the wrong setting.
Run cooler, too, because it can be up to 85% efficient, meaning less waste heat from the supply. Compatible with both ATX 2.0 and ATX 2.2 systems, it includes long cables for even full-sized tower installations. Nvidia SLI support It includes power connections for six SATA drives. A 120mm variable speed fan with double bearings gives good airflow with minimal noise. Active power factor correction helps deal with inductive loads (drive and fan motors, mostly).
A modern power supply for modern computers, just for you.

80 Plus CertifiedThe 80 PLUS certified power supply provides high power efficiency of at least 80% at any load between 20% and 100%, saving your money on your electrical bill, reducing heat in your computer's system and prolonging its life.
Pros: Every connector you could ever need. VERY quiet fan. I'm running 2 HDD's, a dual core processor, PCI video card, a few case fans, and 2 DVD-R drives without any issue (as would be expected). One of my buddies referred me to Johnny Guru who gives a top-notch appraisal of this unit:
Cons: I didn't suck it up and buy a good power supply years ago.
Overall Review: I must have bought no less than 7 or 8 cheap power supplies in the last decade. Every time one went out, I rushed down to <insert generic computer parts store compatible with newegg's review policy> to buy the budget $30 everyday low price, everyday low quality power supply. This time when the original power supply that came with the case died on me, I thought I'd see what the expensive power supplies were all about. My conclusion: "they're worth it."
