Well, 450W PSu with a 16A 12V Rail.
I would suggest you consider replacing it once you get your HD issue sorted.
It looks as if you are OK for the time being but ...
To put things into perspective, a good quality Power Supply, such as a 400W Corsair for example:
The 400W has a 30Amp 12V rail, and 80% effecient. (Pull less power from the wall to do it)
Although it may not sound like it, looking at the wattage alone, its a MUCH more powerful and effecient power supply.
There are other good brands as well.
Just a thought, but I would certainly consider it.
The cheaper ones they put in machines sometimes simply scare me TBH.
Also, keep in mind its possible its currentlt having issues once everything is up and running, or at least borderline.
