I'm trying to figure out how much I need to fork out for a new system and being "short" on cash I want to reuse my old parts as much as possible.

What can you run with an Enermax 450w PSU? Bought it 2 years ago or so, paid a hefty price for it.
I'm not quite sure what I'll build yet, but it'll prolly be :

I5
no SLI or Crossfire but it'll be a DX11 card and probably ATI
2 7200 hard drive
1 dvd burner
4 or 8gb ram (still undecided)

still undecided on my case, maybe antec 900, read good reviews.

Oh and no ocing.

So, do I need to uppgrade my PSU? If so, I want somethng decent that'll run this without costing 200$

Thanks!
 
Argh... should have noted it. I'll post it once I get home from work (3 hrs to go!!!)

Yes, very important info to know.

But in general, a good or high quality 450W PSU with 33A on the +12V rail would be enough for your proposed setup. So now the real question is: Is that Enermax 450W a good quality PSU with enough amperage?

Can't answer that question without knowing the PSU model.
 
Alright.

Enermax EG465P-VE

Reading the box it says 32A on the +12V tab.

Thanos for the help ! :)
 
That's a very old Enermax unit, and I wouldn't recommend it for a new build.
 
ok...
what's the difference, I'm 1v short is it that big of a deal? Even if it's a bit older?

I mean if a 450w with 33v would have been fine?
 
1a short you mean. Amperage can be a very big deal.

It's not just the rating, but also perhaps the age of the unit. The older a PSU is, the more degradation that occurs in its capacitors and the less capable it becomes overall.

If I were in your position, I would chance it on the premise that a non-overclocked setup shouldn't draw that much power. But I'm a little loony, and Zero82z's advice is sound if you don't want to risk parts going up in smoke.

It's not the amperage, but the fact that it's an old PSU based on an old design. It lacks APFC, it has low efficiency, and it is most likely not capable of supplying its rated power simply because of its age. Not to mention the fact that it also doesn't have the proper connectors to run a modern system altogether (you can use adapters, but that isn't an ideal situation).
 
Makes sense.
Thanks for the help guys, guess I'll add a PSU to my buy list!
