PSU 101 - Help a new guy!

post #1 of 11
Thread Starter 
Okay, so after scowering this forum for the past couple of days, I have compiled a general idea of what I want my next build to be. I have decent knowledge of a few things, but expect this to be one of many posts on here.

One thing I have no idea about, is Power Supplies, or electricity in general.
I looked at the stickies, and they were selections within wattages, and how to run two at once. But I don't know what wattage I need, or pretty much anything else.

Here is my proposed rig:
Case: NZXT Phantom
CPU: i7-2600K
CPU cooler: Corsair H-70
Mobo: GIGABYTE GA-P67A-UD4-B3 LGA 1155 Intel P67
Ram:8 GB (4x2) Corsair / G.Skill 1600 or 1866 DDR3
GPU: Don't know enough about them to know what's good... work in progress.

My overall goal budget is $1200 (CA), give or take a couple hundred.

Bsaed on other members rigs, they seem to be running mostly Corsair.

So, any help would be great!

Your choice of PSU hinges heavily on your choice of GPU, so figure that out first smile.gif Generally speaking though, a good 400-450W PSU is enough for a lot of systems with single GPUs (excluding the really power hungry GPUs) and a good 550-600W PSU is enough for a system with any single video card on the market.

Corsairs are good power supplies. So are OCZs, Silverstones, and Mushkins.

For your setup I would recommend an 850 watt (single rail or not, does *not* matter contrary to what some say) to give you room for a multi GPU setup later on. Go with a name brand.

So does the wattage have to be 'compatible' with everything? Or is it the case that the more the merrier?

And is this puppy overkill?

Or would something less powerful suffice?

It's a decent deal. It's about on par with the Corsair TX750v2, maybe a little more ripple and a slight efficiency hit. Costs the same as the original TX750 though, which it's better than.

Completely depends on the model.

@OP Decide what GPU(s) you'll run first.

Thanks for the help, off the the GPU forum. I'll be back!

To put it simply, you can never really have too much wattage. However (and that's a big however), there just comes a point where you're paying extra money for wattage you'll never need. Also, running a powerful PSU at low loads causes it to run less efficiently. Those are the two main reasons why a PSU should be picked in accordance to what it will be powering, not in accordance to whatever crazy upgrades may or may not happen within the next decade.
850W is overkill for anything less than a pair of GTX 480s/580s.

Okay, I had a couple of posts in the GPU section, so time to give this guy a bump and add a bit of info:

a) GTX 460
b) GTX 470
c) SAPPHIRE 100282XTREME Radeon HD 5850 Xtreme 1GB 256-bit GDDR5

Is what's going in on to my rig. I've also decided for an i5-2500k in lieu of the earlier proposed i7. If that effects power at all.
