I bought a Secure 650VA UPS, but it is not working as expected.
I tested it by charging it for 6 hours. I then plugged in my desktop PC (just the PC, itself, not the monitor). I cut the power off by unplugging the UPS from the wall socket. Rather then powering the desktop for a while, it continuously sounds an alarm and then shuts down.
My PC is low-end. I don't think it consumes more than 250 watts. Here's my specs:
- A10 6800k Richland
- 4GiB 1333 RAM
- Gigabyte G1-A88x Sniper board
- 500GB Toshiba 7200rpm HDD
- Coolermaster Seidon 120XL
- 1 Coolermaster LED Sickle Flow 120mm
- 1 NZXT 120mm Case Fan
- 1 NZXT 140mm Case Fan
- 1 Ordinary 120mm Led Fan
- 500Watts Hec powersupply 80% efficient
