Do I need a pure sine wave UPS for my Corsair HX1050

Recommended Posts

This is my PSU:http://www.newegg.com/Product/Product.aspx?Item=N82E16817139034

 

My choices of UPS:http://www.newegg.com/Product/Product.aspx?Item=N82E16842102134

CyberPower-900 watts-2 minutes at full load,Tripp Lite-940 watts-4 minutes at full load.

 

Question is does the CyberPower's pure sine wave support(?!?!) cover the less backup time?Will it really make a difference and protect my PC?Or should I not worry about that and go for the more backup time.

You shouldn't continue using a PC during a power outage. The UPS is there to keep the supply "clean" at all times and allow time to close all files and safely shut down the PC either via the supplied UPS software or manually by the user when a power outage occurs.

 

You're obviously going to have more than two minutes unless you really are using 900W at all times which I doubt (probably more like 300W which gives you 6 minutes).

UPS units, regardless of the manufacturer, have been designed the same way for the past 10-15 years or so. They all provide a sine wave which is 98%-99% true. It has to be because of the Electrical Engineers Standards and Practices guidelines as defined by U.S Law. But, T5 is correct. your UPS should be used to allow you a do a proper shutdown until the power comes back on.

I've always been satisfied with my Cyberpower UPS units.  I've been using them exclusively for a few years now and I continue to buy them.  Considering the price they are usually a darn good value.

 

You won't have any worries running your current power supply with the CP UPS that you're looking at.

 

In fact, considering that you only really need your UPS to allow for a proper shutdown, you could make due with a smaller unit.  I use this one on my primary gaming rig (see sig) and it has been trouble free for over two years now;

I suppose we are but as previously mentioned if we knew your hardware and what you do with your PC it could be that a smaller unit would be suitable. No point in buying a 900VA unit if you don't need to.

Very nice system!

 

I take it you haven't got a dedicated graphics card yet?

 

I'd go for the Cyberpower, it's probably more than you need but should serve you well especially since you intend overclocking and fitting a 790. It will keep you going for a few minutes but if your monitor is powered from this source and you continue gaming I'd be looking to power down after a few minutes during a power outage.
