Thread: AVR, UPS, line conditioner or surge protector?

Thanks.

there " Power Shield " , " Defender 1600" http://powershield.com.au/doc/MLA367...20Brochure.pdf

as long as the UPS outputs a " sinewave " it should be fine , some cheepies have "square wave " inverters
this model also allows you too connect up a USB cable , and it will log all " power events " in a file on your PC , handy now that the federal government has forced our Power company to pay us for bad service , $120 a year for black outs totaling over 20 hours , $280 for blackouts over 48 hours per year , lol

Darwins bad power comes from the 1975 " Tracy rebuild " , it was all installed at the same time , and now substations are self detonating because of age , they all need replacing at the same time , because they were installed at the same time , but they dont have to budget to replace them all, we do not have any "private power company's " too choose from ( no company is stupid enough )

my PSU is a 1200watt Antec True Power Quattro
over clocked and running a pair of Nvidia Teslers
42inch monitor

The HTPC uses a total of 152W (measured at the wall socket, so the PC is consuming less than that after you allow for the 80% efficiency of the PSU). While testing the Eaton software I found the UPS would happily run the PC for 10 minutes or more provided I didn't run the monitor off it as well.

I've done a few simulated mains failures, and everything shuts down neatly as it should.

Our main problem is power cuts rather than brownouts, but the area is also prone to spikes from lightning strikes. I have a switchboard-mounted surge protector to guard against those events.

I'm sure APC have similar software for their UPS range ('Powerchute'?), but their UPS range cost more (for the same capacity) than the Eaton.

Thanks for feedback.

I would be happy to buy a APC product if it makes sense but I still know their unities aren't compatible with active PFC based PSUs.
My computer often runs 24/7 while I can't attend it so a very good UPS is a must.

I prefer to buy from Scorpion Technology or CPL because I can pick up and if things go wrong I can return it to the shop and deal directly, also they're reliable and prices aren't too bad.
Alternatively I'll buy from a reliable eBay seller.

Ah...so its you is it?? Every time you decide to play a game all the lights in your street dim a bit

That's one monster setup

I put a 750W PSU in my latest PC, but only in anticipation of upgrading to a better video card when I can afford it. I guess you need the SLi setup to run such a huge monitor.

mainly for graphics rendering of CAD , i dont play games on it , but the street lights do dim when the "FANS" for the pc turn on
dont need it but editing CAD in full render is cool , and no waiting when you roll an CAD item on the screen

the ROG "cross hair 4 extreme ' motherboard allows different cards in 5 PCI-E slots to run at the same time but as its AMD , there is no SLI

2x Nvidia Tesla C1060's dont have monitor plugs , so also run a NVIDIA GeForce GTS 450 GPU 1GB

the 1200 watts is a bit of an over kill but couldnt find another PSU with over 30amps on 3x 12volt rails , this PSU has 6x 38amp 12 volt rails , and its the first PSU ive seen with a 15 amp plug on it

Here are the pictures of the back PCB.
I feel like it was assembled by an apprentice so this most probably was the reason for its failure.
