Re: [ups] help me shop for a new ups - Buzz - 07-31-2011 Fry's has the BR1500G for $115 for a week (or less) about every two or three months; worth keeping an eye open when in need... Re: [ups] help me shop for a new ups - Robert M - 07-31-2011 Chak, Are you sure? Several sources I found online suggest the battery is connected in a manner that ensure there is never an interruption in the flow of electricity. I may have phrased it incorrectly but that appears to be the design, depending on the type of UPS.

Online UPS ensure a continuous flow of juice. Line interactive and offline models both have an interruption slight as it might be, between the switch from main electricity and battery power. There is no interruption with the online models. Robert Re: [ups] help me shop for a new ups - Chakravartin - 07-31-2011 Robert M wrote: Right. My intent was to point out that the hit on the battery isn't what was implied in your earlier post and to talk up AVR. (I won't buy a UPS that lacks AVR.) Re: [ups] help me shop for a new ups - OWC Jamie - 08-01-2011 I don't think I would spend the extra money for a sine wave UPS for a computer. Unless you switch to back yard back-up generator a lot. They can be a bit sloppy . Re: [ups] help me shop for a new ups - mattkime - 08-01-2011 Buzz wrote: I 'd definitely take that if i knew it was going to happen. Re: [ups] help me shop for a new ups - Spiff - 08-01-2011 There were a couple of threads about this in the past few months. It all depends on what computer you are trying to hook up to the UPS. If you are using a 'puter that has Power Factor Correction (PFC or APFC), then a sin wave UPS like this one (that I bought) would be beneficial http://www.newegg.com/Product/Product.aspx?Item=N82E16842102134 PFCs will sometimes not be compatible with other UPSs depending on the power delivery wave type. Look up UPS and PFC. Some good articles and comments about this on the internets. I like CyberPower so far. But, I've not had a power outage since getting it. I'm running a MacPro (four internal drives), external drive and Dell 24inch LCD monitor. APC tends to have loud fans, which is why I went with CyberPower. YMMV -Spiff Re: [ups] help me shop for a new ups - Robert M - 08-01-2011 Spiff, Glad you posted about this. I have a feeling this is probably why APC recommended a SMARTups for me. I'm going to contact Apple and APC and find out if my Mac Pro has a Power Factor Correction (PFC or APFC) type power supply in it. I already have a UPS that produces sine wave output but it'd be nice to have Apple or APC (preferably Apple, of course), to confirm the type of power supply in my tower. Robert Re: [ups] help me shop for a new ups - mattkime - 08-01-2011 this thread would indicate that it does - https://discussions.apple.com/thread/2728724?start=0&tstart=0 if it does and i have a simpler/older power supply, what happens? (i'm tempted to do a test!) |
