Insufficient Power Supply?

I upgraded my processor, gpu, ram, and motherboard lately and have encountered an unexpected problem. With everything connected I get a very loud piercing scream-like sound but cannot pinpoint the location precisely. However when I downgrade back to my old gpu it goes away. Is this because my power supply is too weak? If so does anyone have any recommendations?

This was my older setup

ASUS MB P5WD2 Premium Socket T (LGA 775) Intel 955X ATX Intel Motherboard

Thermaltake XASER, Armor Series VA8000BWS Black Aluminum/Steel ATX Full Tower Computer Case

2x LITE-ON 16X DVD+R 8X DVD+RW 8X DVD+R DL 16X DVD-R 6X DVD-RW 16X DVD-ROM 48X CD-R 24X CD-RW 48X CD-ROM 2M Cache ATAPI/E-IDE DVD Burner

Western Digital Caviar SE16 WD2500KS 250GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive

Western Digital Caviar SE WD5000AAJS 500GB 7200 RPM 8MB Cache SATA 3.0Gb/s Hard Drive

Kingston 2048MB PC4200 533MHz Dual Channel DDR2 Memory (2 x 1024MB)

XFX PVT84JUSD4 GeForce 8600 GT 256MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card - Retail

Whereas my new setup has

Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor - Retail

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000) Dual Channel Kit Desktop Memory - Retail

EVGA 512-P3-N801-AR GeForce 8800 GT 512MB 256-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card - Retail

Any help would be appreciated

Re: Insufficient Power Supply?

Hello SkylanceFS and welcome to TSF...
Could be PSU... For how long you have this one???
Also, since with your old graphic card your PC works fine, could you maybe hook your new graphic card to some other PC and check what will happen???
If on other PC new graphic card is running fine, then you should consider buying new PSU...
But would be nice also if you can borrow more powerful PSU and try it on your PC with new graphic card...

Check this out:
Power Supply Information and Selection

Read this article and I hope you will find what is the best for your PC...
