So I have a 875 watt psu, (Alienware Aurora R4). Please don't judge, i'm doing a custom build soon. Today I was playing on my computer then I put it in sleep mode. The weather channel said there was some chance for showers, so I didn't think the power would go out. Well, it did. The good news was my hard drive was not doing anything. I have a surge protector but not a UPS. So I boot up and it says "Resuming Windows" it didn't ask anything about safe mode, just put me at the desktop. Now everything is running great and nothing is gone. However i'm worried the loss of power could have shortened the life of my PSU and possibly my whole computer. So is my computer ok, or should I worry? I made sure to unplug when the power went out. Thank you very much!
Is my PSU ok?

Neither an adjacent UPS nor power strip protector protects hardware from that outage or spike. Spike protection is only effective when located at the service entrance. UPS is temporary and 'dirty' power to protect unsaved data; not hardware.
A power outage is no different than any other normal power off.
Nothing in your post implied damage. Your disk drive's computer is constantly doing something. Even if writing when power goes out, then worse that can happen is an old file remains and a "being written" update was lost.
Power loss does not harm electronic hardware. A completey different anomaly (ie spike) must be averted by something you apparently do not yet have. Since computer users need not ever disconnect or power down with approaching storms. That destructive anomaly occurs maybe once every seven years. Even your power strip needs a properly earthed 'whole house' protector..
Meanwhile view your Event (system) logs. Any problem that the OS is working around would be logged there.
It is probably a good time to learn about other diagnostic tools. For example, every drive manufacturer provides them. Get it from their web site. Or many third party diagnostics on the Ultimate Boot CD. Best is to execute them now to learn what a good computer reports.
