New Computer Build Started but turned off immediately

[bonoz]

Hello,

I just built myself a new computer. After putting everything and connecting it together, I tried to test it by connecting it to power. I turned it on. Great. Everything is running fine, windows is booting up, etc. But it turns off!!! and it won't start back up.

I was however, trying to adjust the power cable of my fan controller when this happened. I have a 500W power supply and I am running an AMD Phenom x2, 2x2GB ram, Radeon Hd700, 1 SATA HDD, 1 CD ROM, and 3 case fans.

Was this too much load? If so, have I blown a fuse or something? Is the PSU gone?

Please help. Thanks.

I think it may be my PSU. Just tried another PSU and it seems to work. I would use this one, but it's only 450W.

Do you think if I am running:

AMD Phenom II X2 3.2GHZ
GIGABYTE MOBO
2 x 2GB DDR3 RAM
HD5770 Radeon Video Card
Creative Audigy ZS Soundcard
250GB SATA HDD
4 x Case Fans
1 x DVD Drive
1 x Floppy Drive
1 x Fan Modulator

Is it too much for a 450W PSU?

Thanks
