Is my PSU Powerful enough?

post #1 of 15
Thread Starter 
I have an Ultra X-Finity 500W power supply, with two 12V rails at 16A and 18A (http://www.ultraproducts.com/product...&productID=383)

Would this be enough to power a E6320 on a DS3, 2GB of ram, a HIS X1950Pro, a Tuniq Tower, one HD, one DVD drive and 2 case fans?

Thanks,

Nick

It would power it, but to be safe i'd get something stronger.

You should be safe. But you'd be a lot safer with more juice

12V*16A= 192W...+....12V*18A= 216W, for a combined total of 408W of 12v power. The other [3v and 5v] rails produce the remaining 92W of power to total 500W.

Now, to keep a PSU in its optimum range for efficiency, you need to maintain a load between 40-70% of its maximum capacity. That will ensure you good voltage regulation to all rails, and prevent droopage.

That said, I would go for a higher output PSU. A 600W, should leave you with more 'room' to upgrades and OC.

Well, the 18A and 16A on the 12V rails are a little low... to power an X1950Pro requires 450W with 30Amps on the 12V rail, so you are barely meeting the specs. I'd go a little higher.

Try the 600Watt version of the PSU you picked,

or try the 600W OCZ GameXstream - it's actually less $$ than the 600W Ultra, and still a great PSU. (Maybe even better, looking at the specs).

I'd love to be safe, and if I do get a new PSU I would go with the OCZ GameXStream 600W as I have used that in a build for my friend and I love it, however a new PSU would add another 100$ onto my 800$ upgrade, which is really pushing how much I can comfortably spend on one upgrade...

But if I am able to run the hardware without crashing thats good enough for me, and when I come across the money I will invest in a nice PSU!

But... it WILL run right?

Yeah, I'm not saying it's a bad PSU at all... I actually think it's a pretty good one. It should run your equipment okay, but I'd upgrade as soon as possible just to make sure you're supplying enough juice.
