Need a new PSU

[vaio-fx]

I reckon I need a new PSU, i got a new motherboard and now the PSU makes schreeching noises and gets very hot, the noises start when I have been playing a game or have had the PC on for about an hour or so. So if it is the PSU, could somebody please reccomend me a good one, but I dont want to spend too much money on one. Here is my PC spec btw:

PSU: 650W
Motherboard: nVidia nForce 680i SLI
CPU: C2D E7200
GPU: 8800GTS G92 512MB
Drives: CD ROM, DVDRW, 400GB , Sound Blaster X-FI Xtreme Gamer, USBs etc
4GB DDR2 800MHz
4 Fans
Zalman CPU Cooler
1x Floppy Disk Drive

Thanks for any help.

I'm not sure whether a 500W could suffice that, if so go with the Antec Basiq 500W. Otherwise look at some OCZs. They're relatively cheap.

A quality, inexpensive power supply would be the Antec Basiq BP500UB 500W as suggested by JogaBonito1502 for only $39.99. 500W should be plenty for that system.

If you want a bit more power, the OCZ StealthXStream OCZ600SXS 600W for $79.99 ($54.99 after $25.00 Mail-In Rebate) would be another great choice.

Screeching noise? Are you sure that's not a squealing cap on the new board? That seems the most likely cause.
