Ugh, 400w not enough?

post #1 of 17
Thread Starter 
I just made a thread asking for a PSU-Calculator so I could avoid asking a question like this, but I didn't like what the calculator showed, so I'll double check with you guys!

I was planning on using a Ultra 400w modular PSU...

The computer I'm planning on using is:

Gigabyte DS3L Motherboard.
Intel Core 2 Quad 2.4ghz.
DVD-RW Optical Drive.
1 7200RPG Hard Drive (Eventually upgrading to 2)
2x1gb Memory (Eventually upgrading to 4x1)
Nvidia 7600GS Video Card (Eventually upgrading to 88GT, 88GS, or 9600GT)

According to the calculator using a 400w before I even upgrade would be a stretch. I was figuring it'd be enough even after I upgraded...

No? If not, would an ultra 500 be sufficient?

I think a 400W would work, but it would be cutting it close. I think you'll be fine with a high quality 500W power supply, I'd recommend the Corsair HX series.

Yeah, once you upgrade your video card you might be up a little further than 400w would take you... a good 500w should do you fine though.

Yeah, I agree. And I am in love with my Corsair HX520W. It's modular!

Btw, I posted the url to the PSU Calculator everyone likes so much in your other thread!

A quality 400W power supply will be plenty for that setup.

Which Ultra 400w? They have 4-5 different modular PSUs in that range.
Once again...

Watts is only part of what matters.... many "Watt" ratings are misleading.
Amperage on the 12+
Efficiency %
Whether or not your MB requires the EPS power connection
Those are a few things to look at too.

I think you are going to want a little more juice. The ultra isnt very efficient and doesnt have the highes amps on the 12v rail. you will want something better if you plan to overclock that quad.

According to the psu calculator, at 3.55ghz 1.41vcore my quad draws 180watts (just the processor)

I don't know what EPS is?

I know Ultra's 400w has like 20a per 12V, and the 600w has like 35a. So they seem pretty solid to me. I think they have a 78% efficiency? Or something like that. Plus they're modular and very inexpensive! Ultra is the only way for me to go, I think.

I've decided that it's only worth it for me to get the 600w over the 400 and 500. The 400w saves me about 10$, but it may not be enough power for the upgrades I hope to get. The 500 is probably enough but I can get the 600w for practically the same price!

Thanks for all the help guys.
Feel free to keep the feedback coming, but I think I made up my mind.

Ultra XVS 600w ftw?
