CSGeek wroteI wouldn't spend $2500 on a new computer, because add 1-2 more years and you'll regret it because the price will be less than 50% original. I would rather spend THAT much on a service plan that would always provide me with an up to date computer. Anyone knows some shop offering similar services? Say they will upgrade your desktop every 1 year for a small amount of money..
CSGeek, that's the case with almost everything, my friend isn't it?

xterm wroteAli-mstr7,
I appreciate your help, but what would you recommend? Decrease the PSU? Please take a look at pcandparts and recommend something for me.
I think I can still make a change.
i recommend keeping your psu of 800W for future use ( SLI /CFX).
MGE Eaton E-Series NV 1400H 1400VA UPS w/ Power Management USB Port for
$165.00 would be very good for it , i like the Power Management feature in it since i am using MGE Eaton E-Series NV 1000H 1000VA UPS ,
that will be for
35 $ more and you will be comfortable
another cheaper option could be the Mercury 1500 VA UPS for
$126.00 , but
MGE is better than
Mercury i think .
MrClass
well Ali is correct. I do recommend a better UPS, though the 1000va can still pull it off. I have an MGE 1100VA, and I get 16 minutes. I have a 1200Watt PSU, yet I am using much less. I am sure the 1000VA will provide at least 5-10 minutes.

I'll make the change, thanks ali

Wait a minute! Having a larger power supply does not mean that it will draw more! It simply means that it can provide higher sustained and peak output power. Thus, it houses larger, better, higher quality components and achieves higher efficiencies than lower output power supplies. There's also lifespan, too. A system drawing 500-550 Watts from a 600W power supply, will, in the long run, reduce the lifespan of the power supply since you're drawing more than 70% sustained power. Check any company that sells power supplies (eg. Corsair), they rate lifespan at 70% load (100000hrs). I don't think you'll keep a power supply that long, but it is one of the things that gets migrated from one system to another, especially if newer parts are optimized for power draw (example: An 8800Ultra may draw up to 185W, while a GTX 580 may draw up to 250W. The GTX 580 is more than 3 times as fast. A GTX 480 draws more power than a 580 while being slower ~20% -- the Pentium 4 was around 90W and the Pentium D was an awful 130W. Now the Core i7 CPUs draw up to 130W and they are ~4 times faster (unsure)).
Let's take an example:
You have a 1000W power supply and an 800W UPS. If you draw 500W, then there is no problem for either.
If you draw > 800W, the UPS shuts down. In such cases (as an upgrade or new system), you can simply replace the UPS. Its batteries will have died / weakened anyways by the time you upgrade to something significantly more powerful.
Now let's say you have a 600W power supply and an 800W UPS. If you draw 500W, then there is no problem for either. You may shorten the lifespan of the power supply. However, if you draw > 600W, the power supply should shut down to prevent damage / you may be running it off a cliff). By the time you upgrade to a more powerful system, you will be replacing both PSU and UPS.
Now I'm not telling you to get a 1200-1800W power supply for a 550W system load, but always leave a bit of headroom for future upgrades. UPS's tend to be upgraded more often as their batteries wear out. Even if your power supply was capable of providing higher output than your UPS, you should then have no problem AS LONG as your system isn't drawing close to the limits.
NOTE: I always prefer to look at the max sustained power draw as an absolute limit. Peak, to me, is only relevant when booting up, for example (much power is drawn). a 1250W power supply may be able to sustain 1250W and peak 1500W, but do you really want to be running it at 1250W load? I don't think so. This is especially true of systems where load is continuous (workstations, folding machines, rendering machines, etc...).

Yes, but the UPS still has to cover for the largest amount of ppwer consumption. It's a worst case scenario. The max power consumption could be lower then the PSU limit but this calculation becomes fastidious and unreliable. Anyway a big UPS can't hurt for extended power cut, unless the budget is getting tight, in this case you have to pick smart. Also note that if you're Ups turns out to be too small, there are things that can help, like for example wiring a sleep button to the front panel, and not plugging the lcd in the ups, this way you can hit sleep when you have a power cut and it should be sble to sleep in this state forever, albeit with an annoying beep... ( i once opened the ups and disconnected the speaker because that beep was so annoying).
Some ups can be connected to the computer and trigger a shutdown/hibernate when they run low on battery. It woul also be good to pick pne that has a discrete beep, but you usually dont get the luxury of looking into such things in Lebanon.
It's funny, picking a UPS has never been an issue for me.

no problem ^^

to make every thing clear , i will be happy to know that my UPS ( E-Series NV 1000VA ) would handle a 800W PSU , but i also experienced before such a difference leading the ups to fail and could hurt the PC .
I DONT KNOW if my OLD 800 va ups was not good by it's design but i know it is 800 VA .
And to be onest and cross this headache , get a better one , it is not a big deal in price .
thank you
yasamoka for your info :)
P.S : MY MGE Eaton E-Series NV 1000H 1000VA UPS gives me a MAX of
1 hr with the pc and one 20 "LCD ( WHEN NOT GAMING ) , when gaming it is
45 min .
also check this old thread from a lebanese site
http://forum.vcoderz.com/new-pc-t14297/index14.html
pcandparts itself recommended minimum 1200 VA UPS for 700 W

you will be happy to know that the
( w/ Power Management USB Port ) feature provided in my ups and the ups that xterm may order from
MGE Eaton brand can do what you have listed above , ups beep could be disabled , you can let the ups shutdown-hibernate-sleep ... when it is on battery low at any time .. the program is so cool .
here is a picture for it :

@xterm
Particularly for buying a computer, a service plan will save you a lot of money! I guess everyone agree on this, but the question is is there an offer of that kind here in leb?
In developed countries, you buy a phone lets say (latest device) and pay a subscription of 15$ per month, you will have a valid line along with the device. But you won't own the device. Later on you can upgrade it!

@CSGeek:
I'm not completely okay. It would be cool if you need to keep up with technology. Gamers for instance would love something like this.
But for the rest, your pieces can last super long. I still find great use for an old Pentium IV I have at home.

@rahmu
The idea is that you can buy 10 P IV's now for the money you originally bought it from. The idea is why to *own* a super computer now if you can rent it for a lot less, and considering upgrade.

I honestly don't want to be limited by prebuilt or branded systems. I want full control over what I want and the ability to modify it any time I please.

Damn it samer, Lebgeeks is really SEO optimized.
I updated the PSU just now and searched on google for: MGE Eaton E-Series NV 1400H
Second result is this lebgeeks topic >.>

My advice? Don't use those power consumption calculators unless they are proven to be very accurate...my system with a core i7 930 @3.6GHz and a GTX 260 OC with 3HDs gives a 850W PSU recommendation. Although I do have a 850W PSU, it is based on my own projections for power consumption / lifespan and is, as I see now, approaching overkill. However, I felt peace of mind when I ran 7 HDDs and a 9600GT phsyx card off that thing. No power problems at all.
What I recommend is, check the TDP, then check reviews, look for each parts max power consumption (including mobo and fans and pci cards and dvd drives) then compare the two. For most parts, they should be very similar. However, some manufacturers define TDP as heat-related and some describe as max power drawn under worst case scenario load. Furmark can cause graphics cards to use 50-100W more power than any other software (it can burn them too, so watch out). Add the figures up, divide by 0.7, and you've got it made.

You just scared the **** out of me.
MrClass
xterm, you will be fine with your parts. I guarantee it.
xterm
Ok MrClass.
I faced another problem as well, Asus GTX580 is out of stock, they're getting a new stock in max 10 days, so meanwhile they'll provide me with a normal graphics card and replace it when they get the new ones.

Funnily enough, I had already told them to reserve the parts.
