Hi all.. Well..Ive virtually built my machine but now im stuck on which power supply to get... I want to make sure its powerful enough to run my machien but I also dont want to put in too much power or blow my machine up.
My computer consists of:
ATX Sunbeam Samurai Case
Asus A8N32-SLI Deluxe Motherboard
AMD Athlon 64 FX57 2800 MHz CPU
GeForce 8800 GTS 640MB Graphics Card - 400W or greater power supply with 12v current rating of 26A
4GB DDR Ram
Creative Sound Blaster X-FI Fatal1ty Xtreme Gamer Sound Card
2x Seagate Barracuda 7200.11 500 GB Hard Drives - thats 1000GB total
Pioneer BDC-202BK Rewriter DVD Rom
Iomega Internal Zip Drive
Scythe Card reader and Flopy Drive
And there?s a couple of fans that need to be plugged in as well.
Any idea on what size power supply to get and what the best makes are?
Need anymore info just ask..
Cheers
Mike

You won't blow up your PC by using a too higher rated PSU, all it means is that if the system requires an amount of power to draw from the PSU it will be able to (up to the rated power of the PSU).
You want something that can handle high amps on the power rails, and ideally has a high efficiency rating.
I use an Enermax Galaxy 1000W and have had no problems with that but as well as being probable overkill for your needs, it is also very big in size and a lot of cases can't take it, I also have a Corsair HX 620 PSU which as well as being high spec has a 5 year warranty and is quiet.
Personally I never touch cheap PSUs and I tend to keep the ones I buy for ages (a lot longer than most other parts).

So i can virtually buy any power supply providing it is higher than the minimum requirments in wattage of the highest wattage componant in my system?
Also when deciding on which higher power i require... will I have to combine ampage or wattage of all my componants and buy a power supply that is equal or greater in wattage or ampage compared to the componants?

I have your motherboard, and I use a 550W Antec TruePower 2.0 PSU. I have had no problems with it.

You just need to add the sum of the parts together.
Motherboard will draw hardly anything at all.
Graphics card will take a lot of power as shown in your first post.
CPU will need a certain amount - going up if overclocking.
All other components add up ie PCI cards, HDDs, Optical drives, Fans Lights, Controllers.
The follwoing will give you a good idea what you need to look for as a minimum spec.

No you cant just buy any power supply as long as it says it's more watts then you calculated. You see the thing is that a crappier PSU might say 500W but blow up after 200W.
Just stick with a good brand like Corsair and you'll be fine.

that link BigDK gave me.. Ran through it and it tells me I need 558w power supply.. Closest I can get is 550w or a 600w..
Can you get one thats just under? or will i need to go for the 600w?

I seriously doubt you need that much power for your PC.
Try to go through it again, you might have messed something up.

When you confirm what you need, it's best to go over, you will always get away with less most of the time, but having it covered is the best way to go, and it allows for future expansion of the system.

So although i only need those 558w I can get away with a 600w without causing any problems?
Understandably when your paying over 1000 pounds for a machine you dont wanna harm it lol

It's old technology, but I have been very satisfied with it, the 17 months that I have had it.
