The size of the 990 isn't mentioned yet by @lahoribadsha, therefore, it's too soon to recommend or suggest a PSU. Is the 990 an MT, DT, or SFF (small form factor)?
A blinking orange power light is indicative of a bad PSU, but without that, a wiser suggestion was made by @nyc10036.
MT, DT, & SFF

990 MINI TOWER is capable of using COTS power supply.

Corsair CX650M works fine with this specific model.

The 990 is 8 yrs. old and CMOS batteries are good for about 5. Unless you already know you replaced it more recently, replacing the CMOS battery may help. If it doesn't, you still have a new battery on your MB. If it does help, it's a cheap fix.
