UPS info request

[buachille]

Hi,

I am thinking of getting a UPS.

I have a 1000 watt psu, two 8800gtx running in sli, and high end intel quad core cpu, and 2 gig of ram. Plus the UPS will need to power a 30 inch dell monitor and 2 routers.

Will this do the business, or do i need something bigger. (In the event of a power cut all i want is time to save everything and shut down the computer, i am not bothered about keeping on working.)

Any replies appreciated.

Cheers

Max load is around 500W.

And VA != W
So you need to check watt rating or if that isn't available multiply VA-rating by 0.55. (only good UPSes have power factor above 0.6)
I would suggest getting at least 1000VA model if you go for general accessory brand instead of big name UPS maker.

Thanks for your reply. Going by the figures you give, a 1000VA model would not give me 1000 watts which is what my psu can put out. Does this not matter because the psu will not be running at full load on my system, or am I misunderstanding something?

Cheers

I've had UPS' from a variety of manuf's over the years and the one thing i've learnt moreso than any other element in a system is that you only have one brand that is worth the money, if it doesn't come from APC you end up regretting it. No matter what the specs say or what someone else tells you about how good something else is APC's build quality, replacemnt battery availability and support wipes the floor with anyhting else. They are simply THAT good. If all you want i a few mins to shut down your rig then 800va+ should be more than enough.

yeah, apc is the only manufacturer i am considering. Just wondering if it's worth it. I've been running computers now for about 6 years and I've never had a data loss due to a power cut.

However, I am still thinking it would be a wise move to make.

You would need something like This when using a 1000watt PSU, simply because, when your computer shuts down the PSU draws it full power, ie. almost 1000watts, so if you have a too low rated UPS, it simply is unable to cope with the power demands from the PSU when the computer is shutting down, so the computer simply reboots and comes on again....

that psu is the one i've been looking at. bit expensive, but i suppose it is cheaper than the consequences of a complete pc disaster.
