Do I need such an expensive power supply for this rig?

[AirForceElite]

Everytime, i ask question regarding power supply, i get told that 600 watt is the only way tog go.

do i really need that much power?
rig:
Gigabyte DS-3
E6400 2.13
eVGA 7900GS KO 256MB
1x250GB 7200.10 Seagate Barracuda
1x Dual Layer DVD Burner
2GB 800MHz Gold Edition OCZ RAM
Case with 2-3 LED fans

I have no plans of ever going raid
i have no plans of adding more than 1 optical drive
no plans to adding another video card...

so how much of power would be efficient for that?
and what is a good PSU in $90 CND range (about $82 USD)

This if you can find a canadian retailer.

500w would suit fine, although many would still find it a waste (I'm watching what I say ).

 

[AirForceElite]

how about 400 or 450?

my budget is tight.
and i use ncix.com to buy it.

i just dont know which one to buy cause ppl tell me i need 600 watt, and then they mentioned how they run raid, and SLI set up or something like that

i was thinking of this:

or this
http://www.ncix.com/products/index.php?...5489&vpn=W0070&manufacture=THERMALTAKE

or this
http://www.ncix.com/products/index.php?...AX450-PN&manufacture=FSP%20GROUP%20USA


they all will run it fine, wont they?

and whats the difference between OEM and retail versions

i know oem is without a box usually, but any other difference?

I wouldn't do Thermaltake. I wouldn't do low quality model FSPs either.

I'd prefer the antec smartpower 500w... Although overpriced for Canadians..., in your range before taxes and shipping and such.

People complain of bad caps, but I've had no problems with antec psu's so far...

Try a Sesonic S12 430 or 500 both should work fine for your system. Just do a search for seasonic on NCIX.com and you'll get all of em, the S12 500 is about 120 CAD delivered and the 430 is around 97

 

[AirForceElite]

so guys, is 400W enough with the conditions i wrote in first post?

 

[Arcanedeath]

400 is the bare min I'd use If you do go that low just make sure it has enough juice on the 12V rail. this is not a place to cheap out Powersupply is one of the more important pieces of your rig.

 

[Operandi]

I would go with this.

And before you ask, yes it's more then enough.

 

[shoRunner]

as long as a quality PSU, 400W would be fine

Remember, Canada's power is of much better quality than the US's so you can get by with a cheaper power supply. There is no reason to buy some cheap POS, but a decent 400W is plenty for you.
