Lately I've noticed a trend where people judge their personal self worth by the size of their the total wattage capable of being delivered by their power supply. You need to read the below..

493W from the outlet converts into ~395W to the system(remember PSUs are rated by output, not necessary input. The PSU used had an 80% efficiency rating so that adds up)
never skimp on the power supply, but know what you need.

Humongous Power Supplies and what you Really Need
Manufacturers are nowadays bound to their respective marketing gurus resulting in ridiculously exaggerated trends which the usual customer tends to overlook. Let us talk about power supplies for instance. With 1000 Watt power supplies available from many companies and 2000 Watt power supplies just around the corner one can come quickly to the conclusion that you really need that much power.
But you don't! Mostly every website out there who puts PC hardware states the electric power consumption or gives a rough figure about it. If you then add those numbers together for every component you have you might be surprised about the result. For Example, the guys from Legion Hardware put together a dead fast machine consisting of a quad-core Intel CPU, two GeForce 8800GTX cards, a feature-packed ASUS Striker Extreme motherboard and four 1GB DDR2 memory modules. Additionally the system had four Seagate 320GB hard drives and six 120mm case fans and let's not forget the water-cooling system. Now reckon what wattage the power supply they used to power that beast was rated at!
550 Watt - They took a Thermaltake Purepower 550w and it works like a charm for more than two months now.
Power supply output ratings are actually quite inaccurate and can be very misleading. This is why it is very important to purchase a trusted and respected brand name.
If you came this far I would suggest you reading that article, it's well written and outlines every aspect of what to have in mind when purchasing a decent power supply.

I'd like to take this chance to explain to you all clearly and simply, you over rate computer hardware power consumption and you all need to learn a thing or two. Especially you, perkam .
This test will include..
* Detailed specifications of the rig..
* Power consumption @ wall..
* 12v, 5v Rail Readings..
* Overclocking, benchmarking..
* ..and more
The specs of the rigs are..
Intel Core 2 Xtreme QX6700
ASUS P5B Deluxe WiFi/Ap
2x1GB G.Skill 2GBGA (D9GMH) and 2x512MB Corsair 8000ul (D9 Fatbody's; for benching.)
eVGA 8800GTX 768MB; vmodded.
Creative Labs X-Fi XtremeMusic
Many-a-fan
AquaXtreme 50z Pump
Seagate Barracuda 7200.10
NEC SATA DVD Burner
Thanks to fhpchris for generously letting me borrow the CPU, video card, and Corsair RAM.
I will be doing some overclocking, hard benchmarking, etc. The most I've drawn so far from this PSU is 493w from the outlet without wincing. Testing will continue tonight, pictures will be taken, and most of the results if not all will be up by tomorrow. Please stay tuned, for the sake of all future PSU recommendations!
