PSU Help

dude12564 · Dec 27, 2011

I have a 350 W PSU with a 18A Rating on the 12VA Rail, and a 12A Rating on the 12VB Rail producing a max of 300W on the 12V Rails.

(Yes it's a dell stock)

My video card calls for a 300W Minimum PSU, with 22A on the 12V Rails (It's a GT440)

I'm wondering if I should go upgrade to another power supply.

Specs:

I5-750 @ 2.66
DDR3-1333 8GB
1TB WD Caviar Blue
Dell Stock Motherboard
350W PSU

If you need any other info, just ask.

Thanks

Yes, so you might as well get the 450 /460 6850 you been eying just to make it a descent gamer.

If its a full size dell you should be ok. But measure the PSU just to be safe. Or post you Serial Tag / Model #

It's a Studio XPS 8100, and do you want the serial of the PSU or the computer?

The generic specs says it has a Nvidia GeForce GTX 260.

What your Tag # white Tag on back

Mine actually came with a HD 5450, swapped it out for a GT 440

I'll get the tag once I go find my computer.

I dont think you need to upgrade. i5 could pull 95w max on the 12v and the GT440 max pulls 65 watts even factoring in leakage or weird stock volt settings combined it wouldnt be more then 175w. Also just assuming your psu is rail 1 cpu and rail 2 gpu/everything else. 18A covers the i5 and 12A covers the GT440 and HDD and Mobo. I doubt you will have a problem if you use the power supply you have.

Alright then, thanks for the help!

Let's put in retrospect this way. Max 12a * 12v = 144W Max'd.

EarthDog · Dec 27, 2011

^^ What? ^^

It should be fine, especially with the system at stock speeds.

current*voltage=wattage and sorry my math was wrong.

Outside of the math the whole sentence structure is what threw me...

He mentioned in the first post that there are 2 rails, 12vA and 12vB as he called it. 30A as listed for the two rails... BUT combined it will pull 300W=25A.

Oh I know what you are saying but they can't be combined like that.

EarthDog · Dec 27, 2011

Correct..I am well aware you cannot add the rails up to get its true output (as was alluded to in my post above). The OP stated 'added up ' totals and the actual combined (as usually noted by some writing on the PSU).

Unless Im missing something...? Either way, I think you and I get it Jr.

Total combined is 300W for the 12V
