Is my PSU enough for this PC?

I just purchased a gaming PC that I built myself. The case came with a 450 watt power supply, and I'm wondering if it is enough to run my system. I've used many calculators and charts (including TigerDirect.ca's chart), and they all say it is enough. The only problem is that the PSU is VERY loud. As well, it heats up really fast. I was just wondering if this is because the PSU is like that, or am I pushing the limits of it. My computer is as follows:

AMD Phenom 9600 Quad Core(Stock HeatSink)
Asus M4N78 PRO Motherboard
Ultra 2048MB PC5400 DDR2 667MHz Memory
Ultra 1024MB PC5400 DDR2 667MHz Memory(3GB Total)
Nvidia Geforce 9600 GSO
Wireless Network Adapter PCI Card
80mm Side Case Fan
120mm Rear Case Fan
CD/DVD RW Drive(with Writer)
500gb SATA HDD
And Multiple LEDs both on the case, and the fans.

Thank you in advance.

(Also if there is a Power Supply Calculator that scans your system it would be perfect.)

There is nore to fetermining if a power supply is strong enough to run a unit correctly.
It depends a lot on how many rails the PSU has & how the power is arranged on the outputs.
If you post the model number of the power supply I'll look it up & tell you what you're really working with.
OCZ StealthXstream 700W,Gigabyte GA-EP45-UD3R , E8500, Arctic Freezer Pro 7, 3GB G.Skill PC8500,Gigabyte Radeon HD 4850 OC [1GB ], Seagate 250GB SATA II X2 in RAID 0, Samsung SATA DVD burner.

Just a thought when you bought Nvidia Geforce 9600 GSO was there any information that came along with it that suggested power usages or recommended power supply wattage. Just by looking at the good stuff you have got (MORE POWER) so you are not working your 450 so hard.

I would buy the case without the PSU because case PSUs usually suck. And get an antec EA650 650W (runs video cards rated at 700 watts usually)

I would suggest to not use stock psu's since they are of lower quality. I think 450W -550W might be good enough for you. Also you don't want it too high because you'll be getting higher energy bills. Just like some consumer reports reviews of some high-end gaming pcs getting bills up to $1,000 a year from the pc alone (I read it a few weeks ago so don't remember exact details).

Dude, it draws the same amount of power no matter what. If you have a 1000W psu it's not going to have higher energy bills than a 500W. Of course UNLESS you use more than 500W.
