480W PSU - enough for a Quad system?

[gamingguy27]

Hello All,

I have a very good Antec TruePower v2 480W psu (decent +12, 36A), and I was wondering could it power my new rig?

Specs:

Energy Efficiant Q6600 Intel Quad @ 2.40
4 x 1 GB OCZ Platinum
1 x 8800 Ultra
1 x X-Fi XtremeMusic

and a couple of 120mm fans...

According to power calcs WITH %20 capacitor aging, the power demand should be around 478W...

Regards,

Alex.

hey hey.... Personally i think you're gonna come up short on power... i say this because NVidia recommends atleast a 450 W power supply on the 8800's. Add the quad and the the other accessories and i don't think your power supply will last too long.

Ya that will work for a while but it will bring you to a world of pain shortly after.
If you dont have alot of moeny try for a thermaltake thoughpower 650 watt or something like that

What power calcs?

TechReport's review of 8800 Ultra with Core 2 Extreme X6800 used 315W on full load. I find it hard to believe that your setup would require that much more.

You have 33amps, not 36:

See if this would do for you:

550w@41amps
The 450w version has 33amps if that gives you an idea

It will work.

I too think power calculators are a joke. I have a Kill-a-Watt meter and ran my C2D with an 8800GTS, 2 hds, 2 burners, under full load and used 248W max. Power calcs did say it woudln't use much, but they were still up in the mid 300s.

So you used a calc, and gave yourself 20% headroom and STILL came up below your PSU's output.
