UPS suggestions

[nsfx]

I'm in the market for a UPS preferably to support 2 machines (one 520 W PSU and one 300 W). At least one of these machines will be running Linux. Anyone have a recommendation to suit these needs?

Thanks

could you give us the specs on both systems? you may have a 500w psu but you might only be pulling 150 watts at the wall.

I'd get no less than a 1500VA UPS to allow for plenty of headroom. APC and CyberPower offer some very nice units. APC is a bit more expensive but they are typically built better. I've been using both brands for 10 years with a few failures along the way, and the 3yr. warranty is a nice touch. CyberPower recently sent me a new battery free of charge after one of my year old UPS'es failed to run longer than 1 min on battery (typical was ~10 min when it was new). A few months ago I picked up a Belkin 1500VA UPS and so far so good.

One of the machines uses a Corsair 520w PSU which has Active PFC, which I understand is not compatible with simulated sinewave output. Any suggestions for a 4 outlet UPS compatible with PFC that doesn't break the bank?

Thanks

Search for "apc true rms". The smart series has some. On Newegg they use seem to use "pure rms". They all seem pricey to me. I bought a smart ups 750 for equipment (not a computer) that requires a sine wave output. It has worked flawlessy.

I just hooked up my HTPC to my APC Backups RS 1200 and it is now drawing a total of 390watts.
That is 2 machines, 2 monitors, 11 hard drives, Alesis Powered Speakers, 20watt desk lamp, 2 Switches, USB hub, 2 Phone chargers, and Zune Altec Lansing Speaker.

the UPS that was hooked up the HTPC has bad batteries, it was old and this last power outage on Saturday took the last of it.

475 watts now with the Xbox 360 turned on and playing some HD content.

I opted for a 550W APC UPS for my gaming rig. It won't last long at full load but any other time and it will last long enough to shut your machine down and then some.

That is not true. I for one have an HX520 that has been running on a simulated sine wave UPS for well over a year without a problem. On the contrary I've seen Enermax and possibly Silverstone claim that you need a true sine wave UPS for use with some of their psu's.

The only issue that we have seen is that when using a UPS with a simulated sine wave, you may hear some slight buzzing in some cases. This will not hurt the PSU itself or the system in any way.

Here is what I get out of various related topics I just looked at. A good UPS will at least have a step approximated sine wave. If the peak and rms values are reasonably close to a sine wave the APFC should not have a problem with it. Still, I find anecdotal postings of some individuals having problem with certain combinations. The best bet would be if someone with a corsair 520w psu would post what ups they successfully use.

My HX520 ran fine w/ a CyberPower 800AVR for roughly 1 year, and then I upgraded to a Belkin F6C1500-TW-RK a few months ago and still have zero issues to report.
