Please help I want to buy UPS for PC because lately, electricity on my house often shut down unexpectedly.
My pc specs:
- Motherboard GA H270 GAMING 3
- HDD WD Blue 1 TB
- RAM 16GB 2400mhz GSkill
- VGA Zotac GTX 1080 AMP Extreme
- Processor Intel i5-7500
- Power Supply Corsair TX550M 80+ Gold

My friend recommend this APC BX1100LI-MS and Prolink Pro1201 SFCU and those two are avaliable in store near me. But another friend said that the Corsair TX550M power supply is enough and I don’t need to buy an UPS.

1. Is that true that my Corsair TX550M 80+ golds enough and keeps my PC safe and I don’t need to buy an UPS?
2. Are both enough and fit?
3. If not, is there any other brand that you could recommend?
I’m worried so much.

Thank you so much if you could help me decide :)

My recommendations are:
1000VA+ (this gives me 3-5 minutes to safely shutdown)
600W (this helps ensure it can provide enough power for your computer, monitor, and maybe router. Don't plug your printer into it)
AVR (this ensures the UPS is always passing good clean power)
Surge Suppression (I don't think you'll find one without it)
You'll want to replace your batteries every 2 years. I think I paid $40 the last time I replaced mine.

You can probably get by with a lesser unit than what I recommend, but I like to stay away from power thresholds. If I need 550W, I don't buy a 550W PSU, I buy an 850W PSU. Same with the UPS. It's also hard to know how long a UPS will keep you up for without knowing your exact load, which fluctuates. You...

Oh ok, then, only sure that it has AVR only? Or is there anything that I should concern about?

It's also hard to know how long a UPS will keep you up for without knowing your exact load, which fluctuates. You might be drawing 100W at idle and 380W at load. Which could be the difference between 3 minutes and 10 minutes of uptime in a power outage.

Oooo, I agree with you. I was down the hall, in the bathroom and the APC 1080 went off. For 7 minutes, it kept my rig going. I imagine it could've gone a few more but it done it's job, no need to test the limits.

smashjohn is right. Get yourself a UPS. The years I've been around electronics, nothing's worse than a brown out (drop in electrical current) or a huge power spike. A UPS will protect you from both. A PSU won't. In the event of a brown out (house lights flicker and dims), the voltage drops below 90v and burns across the circuits. Electricity is too weak, doesn't have the solid contact it needs. It can't flow smoothly across the circuits, diode, electrodes, cpu etc. so it jumps. burning across the connections, contact points and literally fries them. But it doesn't just fry the first component it reaches, it fries everything. Your 'another friend' is wrong. A psu doesn't have the characteristics of a UPS. A PSU needs a UPS. 'smashjohn' has the right solution.
