And what power PSU will the Dell system I have got have come with?

Will I need to crank open the case again and check?

And what else is needed? ANd how do I check?

Thanks in advance

Total power is relatively irrelevent, it's the quality that's more important as there's a lot cheap high power PSUs that deliver a poor current. Dell PSU's in general to be pretty good, what model is it you have?

If you haven't added anything else to the system, it should be able to handle an extra graphics card. If not, I don't think you can actually damage your hardware by using a low powered PSU, it will just lock up? Might be wrong though...
To check the power, there should be a sticker on the side of it, whcih either states a value or just the serial number you can look up online-theres calculators online that tell you how much power your system needs, but not sure how good they are.

This will help you out http://www.journeysystems.com/?power_supply_calculator

check the energy requirements on the box for the card, calculate what you need and you will have the answer.

Nice link Jocksteeluk

But it doesnt really accomodate for new hardware.

My spec is.........

Quad Core Q6600
4GB Corsair DDR2 800Mhz RAM
320GB HardDrive
DVD/CD RW
Onboard GFX currently.

And I wanna add a 512MB 8800GT at some point soon.....

Will try and open computer soon and check what PSU is inside.

If you've quad core with that relatively recent spec, you should be fine to add the GFX card you are thinking of. I should imagine it would have a 400-500W PSU built in. There's no danger even if you get the power wrong, you'll know from lock ups etc. Then just add a new PSU very easily.

But I agree with another poster, unless you have added loads of extra peripherals, you'll be fine. Besides, those GT GFX chips can be had for £50 now so you've nothing to lose. If it doesn't work, just put it on ebay. I find many retailers like Komplett to give superb pre-purchase advice.

More like 350 as my quad core setup with 4 gigs ram was sent with a 350 it worked ok though.

PSUs do degrade over time so you do want some spare when it's new.

Just take the side panel off the case, the PSU should be labled and just note down the table that's on it.

I can build computers lol and did change the psu quickly after anyway as I had loads of my own componets.

use this one http://extreme.outervision.com/psucalculatorlite.jsp
it features new hardware including your vga and cpu as well as a function to calculate the extra power of a system overclock.

I don't know what Dell typically use, or whether it will even be compatible with an 512MB 8800GT. Here is the recommended requirements for a BFG Tech 8800GT:


> 1GB of system memory
> Microsoft Windows Vista -or- Windows XP
> CD or DVD-ROM drive
> 50MB of available hard disk drive space for basic driver installation
> 425W PCI Express-compliant system power supply with a combined 12V current rating of 28A or more (Minimum system power requirement based on a standard PC configured with an Intel® Core™2 Extreme X6800 processor)
> PCI Express-compliant motherboard with one vacant PCI Express x16 slot
> One 6-pin PCI Express supplementary power connector -or- Two 4-pin Molex supplementary power connectors


If it is compliant with that you should be okay. If it is not compliant, go for a 400W+ PSU to be on the safe side, try to get a 12V Version 2.2 PSU which is compliant for your set-up and your new choice of card.

http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=256346 - I have heard these are pretty damn good for the price and it fits your requirements perfectly.

Just cranked open the case......

It says........... Max Power: 350w.....

Other information........ The Combine Power on +12VA & +12VB total 300W

Bardcode number: CN-0FU909-42940-7BM

REV A00


Dont know that much of that means...... I also hear that PSU's lose some of their overall power in time too.... so maybe best to just get a new PSU aswell?

That 400W Phear linked too looks pretty good, but maybe should go 450-500w while I am doing it?
#12
I had one of these in the past, still have it somewhere - its a good little machine but that extra 130W will cost you double the price as the one I listed earlier - Here you go:

http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=408083

Check if the one you have now (the Dell PSU) has a six pin plug like the one pictured here:

Or two spare molex plugs:

If it does, chances are good that it will work fine with the current PSU, although I cannot guarantee it.

Im not sure if it had the 6 pin plug....... but i think it had 2 spare moldex plugs.

The Combine Power on +12VA & +12VB total 300W


That's 25A so it's marginal if the recommended is 28A on a X6800 system.
#15
How you know thats 25A and whats a X6800 system? LoL Sorry dnt know much bout voltage, wattage, and the sorts.

Heres some more detailed info from sticker.

Output - +12VA ---- / 12A +12VB ----- / 18A
+5V ----- / 18A +5Vaux ----- 2A
+3.3V ----- 17A -12V ------ 0-8A

Combine Power on +12VA & +12VB Total 300W.

So we have established that it will probably work ok? But ideally should have a batter PSU?
#16
Oh and im also planning on adding a second hard-drive.... probably a Samsung F1 1TB. so would that make it less likely to have enough power too?

watts = volts x amps. Those aren't the correct terms by the way, but It's been too long since my electronics course and I can't remember the right ones.

If you've got 300 watts and 12 volts then you've got 300 / 12 amps - 25 amps.

X6800 is a Core 2 Extreme processor, according to wikipedia it draws 75W while your Q6600 draws 95W.

Basically you're very close to not having enough power. It's possible it may work, but if it's going to be in there long term then you'll definitely want a more powerful PSU.

Ok mate, cheers for that, REP added.
