500va ups for $29.50 at staples B&M

[flashsim]

HP 500va Beige UPS looks like this
Regular price shows $49.99 on shelf but it has a clearance sign on it for only $29.50. I went to another staples and their signs shows $99.99 on the shelf. YMMV
UPC code is 806978001472

Good luck!

yep i can confirm this... its 99.99 at my store.. on clearance now for 29.50...my sales manager bought one and our recieving guy bought the other one... combine that with the employe discount week and its not a bad deal at all...we are out of them though.. i will check the as400 tonight and see how many are left throughout the country...

Does anyone know how long this would run an Athlon system? Just the box, no monitor...

I have been getting in on all of the APC deals, but without having to deal with a rebate, this looks really hot!

Just picked one up at the San Mateo Bridgepointe Staples.

They still have 2 more in stock. Shelf price reads $44.90, rings up as $29.50

SWEET!

Don't bother going to the Staples Covina, Ca., I just got the only one they had. Shelf price $99, after scan $29. Thanks, flashim.

Picked up the last one at my staples, good deal!

The introduction in the manual is good for a laugh too:

This UPS is a ultra slim graceful, aesthetic and cute body guard, it is exclusively R&D and design for the computer user with 500VA cappacity uninterruptible power supply, you will be ease of your mind by posessing it!
This system features with numerous advantages, which is capable to elevate the stability of operation of the load equipment and UPS.

got the last ones at my staples. They seem good but I have a question. The manual says the ups will work 3 minutes @ full load and 9 min @ half load. Anyone know what the full or half load is?

FYI: this is an HP ups

 

[HappyPuppy]

boa, it means, I am assuming form logical deduction, that it will supply 3 minutes of backup under a 500 watt load and 9 minutes of backup under a 250 watt load. You can figure out how much total wattage your computer is using by adding wattages of each component. If the component doesn't give the wattage you can get it by multiplying the voltage by the amperage.

I don't really expect you to do all this, but you did ask.

good looking ups
got one in wayne, staples

 

[Sir Fredrick]

Happypuppy, it's a 300W UPS, not 500

 

[boa]

This is something I've never understood about UPS ratings.
They display a VA rating (e.g. volt*amp) but as we all know a volt*amp=watt.

Looking at the details of UPS's though, the VA rating might be 500 and the power the ups can deliver (during power outage) would be 300W.

BTW: Sir Fredrick is right about the 300W capable load ups details. I guess HappyPuppy was wrong about the loading.

If you're talkin DC, then yes power = volts * amps

But if its AC, then you can't use the peak-to-peak voltage to calc power.
Its something like AC RMS power = volts * amps / sqrt(2) = 500VA * 0.7 = 350 watts or something like that

You gotta love the UPS companies using VA instead of power. 500 sounds better than 350...

 

[jasonroehm]

Coaster is sort of on the right track, I think. AC power is a completely different animal than DC. For DC circuits, then P = VI, where P is the power dissipated, V is the voltage drop, and I is the current running through the element. However, in AC circuits, then the input voltage is a sinusoid, usually represented by a cosine function. If you have purely resistive loads, then the current stays in phase with the voltage function, and the P that you're looking for, the average power, is equal to VrmsIrms. (Vrms = Vmax/sqrt(2)). Inductive or capacitive loads can cause the voltage and current to get out of phase. The effect of this is a decrease in average power, since the current and voltage no longer line up at their maxima. There is another kind of power, called reactive power. Basically, this represents all of the losses in the circuit. All of this is usually represented using phasor or polar notation, so if you do it that way, it works out nicely and you can figure out your power factor and such from that information. In short, it goes like this: plot average power on the real axis of the complex plane, and reactive power on the imaginary axis. The power that they are quoting, in VA, is the length of the phasor (or vector) from the origin to the point you plotted. The distance on the real axis is the average power, in watts, and the distance on the imaginary axis is the reactive power, in VAR's. I believe the power factor is the arctan of the reactive power / average power. I could be wrong, but I'm pretty sure that's the gist of it.

If there's any EE's out there who want to correct me, go ahead. I'm sure I missed something somewhere.

I just picked up the Belkin 350va at Staples last night. It was on clearance for $39.99 and after my 25 GC and a 10 off 40, it rang up at $8. Nice unit but after I installed the software, it told me it waspowering off the PC in 30 seconds due to a power overload. All I have plugged into it is a P3 1 ghz and a 17" monitor !! Now what was really comical was me trying to turn off the shutdown option within 30 seconds of bootup, which was NOT happening !! :| I finally unplugged the RS232 cable to the unit but ..... damn, it should NOT be powering off with that amount of draw on the line. I also had a set of Labtec Pulse 424 speakers plugged into the standard outlet but even with them turned off it shut down. Any ideas ? Other than this its a nice unit

Just don't accidently log into my old store (0154). I don't think I.S. would be too happy.

 

[boa]

ya'll are right about the power factor. DUH! This just shows how badly the brain has deteriorated after years of programming and lots of gaming. If my college advisor could see me now!

I just picked one up in the Jersey City, NJ (Pavonia/Newport store) store. last one on the clearance rack. I had actually seen this like 2 weeks ago on the clearance rack for $69.99 and was debating buying it. Now it was $29.50 labeled as marked down from $49.90. Good thing I didn't but it.

Was looking for a UPS for the past few weeks and am glad this deal popped up. Went to Chapel Hill, NC Staples and saw it for clearance at $79.99, down from $99.99. Went to cashier and it rang up $29.50. Sweet!

Picking my up today here in NYC, they got one on hold w/ my name on it

 

[sas168]

Zim Hosein : which Staples B&M in NYC? i 'm going to get one.

The Staples on Lakewood & Artesia (91 freeway & Lakewood Blvd) has 2 of these sitting on the shelf. Shelf tag says 79.90 but they come up 29.50. The item number is 446634. I noticed these backups only have 2 outlets in them.

If you want them, you can always call and have them hold them for you. Be warned, someone once said that whenever they see something behind a counter that they're looking for and know is on clearance, they tell the clerk the item is being held for them. You can also call 1-800-staples and give them the item number and they can tell you which stores in your area have them in stock.

I passed on them as I already have 3 APC 350VA's still in their boxes that I snagged awhile back for 14.xx.
