In spite of having an UPS, my PC restarts during power cuts... Please help me

[vijaykec73]

I have a 600 VA (max. output 360 W ) line interactive UPS with over load protection. I am using a AMD FX-6300 processor and Sapphire R9 270X gpu. When I run my PC for normal tasks the UPS backup kicks in perfectly if there is a power cut. But if the power cut happens during gaming (NFS Rivals) the PC just restarts stating that "Asus Power Surge Protection has triggered". So I tried gaming with my friends 1000 VA UPS and it works fine during black outs.

This leaves me with some doubt here.

1. If my PC has restarted during a black out due to a overload on the 600VA UPS then why did'nt the over load alarm trip when there was no black out (overload is overload rite!!) ??

2. Are surge and over load the same ??

3. Have I already damaged my components due to this situation ??

360 W is cutting it too close with that rig under load, isn't it? I think the answer is that simple.
The good news are that your components are probably fine, since that built-in proctection you mention has kicked in.

It has already been answered in both the threads.

That's a very tiny UPS for a gaming system. My system uses 400w on it's own, that's not including the monitor or anything else that may be plugged into the UPS. VGAs and CPUs today suck a lot of juice. Chances are the UPS is going into protection mode and shutting down as soon as it loses AC power as it's inverter can't handle the load.

I would look at getting at least a 1000va unit.

Also, I have seen some situations, especially involving laserjet printers, where the UPS does not trip fast enough during a brown out condition. Laserjet printer kicks on, which causes a huge surge of current and a brownout, UPS seems to almost hesitate or something but by then the PC has locked up or rebooted as the voltage went too low. I'm not really sure what is the solution to that other than putting the printer on a completely different leg or using a dual conversion ($$$$) UPS for the PC (obviously you don't plug the printer into the ups!). At home I don't have that problem but my parents do and I've seen that problem elsewhere as well.

It's possible that he wants to hear an answer other than that he has an underpowered UPS, and that he should spend $$ on a larger unit.

How long have you had the UPS? Have you installed the software? I know on mine the software states an estimated run time and the status of the batteries.
