Please help me on deciding on a UPS/PSU unit for my Rig

[Rehman5000]

Hi all,

I need help with deciding on a good UPS for my Rig.

My specs:
* Intel Core i7-3770 Ivy Bridge (3.4Ghz CPU)
* Asus P8Z77-V Deluxe (ATX Mobo)
* EVGA GTX 660 Ti (2GB VGA)
* Kingston HyperX KHX1600C9D3K4/16GX (16GB RAM)
* Kingston HyperX SH100S3/240G (240GB SSD)
* Western Digital Caviar Black WD1002FAEX (1TB 7200RPM)
* Western Digital Caviar Black WD2002FAEX (2TB 7200RPM)
* Asus BW-12B1ST (Internal BlueRay Writer)
* ViewSonic VA2238WM-LED (Full-HD 22" LED monitor)
* Logitech Z103 (2.1 Speakers)
* Asus RT-N13U Wireless Router

What is the recommended UPS rating that you guys recommend? I don't plan on going more than this anytime soon. I have near-0 knowledge about UPSs... I currently use a Prolink PRO700 600VA UPS... Is this sufficient?

Also, in addition to the above: I currently use the Antec EA-550 Platinum PSU. Is this really sufficient for the above system?

Please help me in this. I am really stuck on this one...

Many thanks in advance guys.

Hi, i'm not a pro in Ups too but it looks like it can't do it. Just found that calculator out there http://www.csgnetwork.com/upssizecalc.html and if you put 550W in pc power it gives you around 770VA while your Ups is 650VA. That's only for the computer so if you wnt to plug something else it will be higher. I guess you can play with the calculator to see what you need. But don't take the minimum, take the suggested number. Anyway i hope i helped you.

Try this one

And if you wanted a new power supply, here's one more than powerful enough and cost effective

Hmmm i am not so sure about that company ... For supplies, i only trust Corsair, Seasonic, Ocz, Antec, Thermaltake, Nzxt, Silverstone and XFX. Other brands are not crappy but yeah .... I have pretty much the same build (Same proc., ram, graphics) and i use a TX750M from Corsair. Works great.

Thanks guys! But I forgot to be clear on the fact that I have already bought the EA-550 PSU (after everyone I know said it was "more than enough")... So I just want to be confirm from you guys; is that PSU really sufficient for my system?

Thanks for the UPS calculator and suggestions... Seems like the stupid a** store cheated me on that... Should've looked for one myself when buying the PC...

A 550W PSU doesn't necessarily pull 550W or more from the outlet. You need to calculate how much power your PC will draw (certainly much less than 550W), divide that value by the PSU efficiency at that load and multiply the result by 100. If a system draws 400W and the PSU efficiency is 80%, then 400 / 80 * 100 = 500W.

Calculate, add a good 100w and there you go. But seriously, 550W is enough for you system. It will not take more than 300W in my opinion.

Thank you all.

So it seems like I can stick to my EA-550, and only need to move from my 650VA UPS to something more powerful...
