While 380 Watts sounds aplenty, you hae a very full machine and lotsa Watt eating parts.

Do your homework with ...

How much power do I need? -> http://www.tomshardware.com/howto/20040122/

Next, you may need to tack on 100 more Wats since not only does the specifications fib, but in one year the PSU will degrade up to 50%. Read http://www.tomshardware.com/howto/20021021/

WHAT THIS MATTERS. A power supply with just enough Watts will dip out or droop and the motherboard power supplies and capacitors will work harder causing some stress there.

IN CLOSING, HEAT IS BAD. If your machine is hot to the touch, then it's too hot in there and your parts are aging rapidly. You will see failures very often with boards, drives and what else is in the hot box.
