New PSU time?

post #1 of 27
Thread Starter 
Getting a 570 today, as soon as I can figure out what PSU to get for it. I was told that Rosewill is bad juju and that I'd need something with a bit more kick to power the card anyway.

Looking at a NZXT Hale 90 right now. Modular seems like a good idea. Any input?

Actually, the Rosewill Green Series is a highly-recommended series of PSUs. So, I say that you're fully covered here! Plus, I imagine that it's better than this NZXT unit. But, I don't know yet. In this PSU's defense, it does have a very strong +12V at a capacity of 648W (54A).

So..530w will be enough to cover everything with a GTX 570? Man, I get talked in circles here more than anywhere else, I swear!

I know. Every single time a brand new series of graphics cards comes out, it seems like everyone goes "zomg you need a 9000W PSU for it!". heh. And then a few months later, they calm down and stop being so uppity or whatever.

NVIDIA's power supply requirements for the 570 call for a 550W. But this is considering a typical system that would have a single 570 in it, such as one with like an i7-920 in it which definitely pulls much more power than the E8400! Plus, they also have to make sure their butts are covered even for generic 550W units. But you have a quality 530W, so you're fully covered.

Well, that definitely makes me feel better about my choice in the first place. Been running it for a few years and no issues with it. Is having a modular PSU worth dropping some cash for though? I do plan on replacing quite a bit of guts over the next five or six months. So while I've got the cash, I figured I'd grab a PSU that will cover those kinds of changes too.

Nothing huge, of course. I'm not going to be running six 580's and a million gigs of ram. Just modest changes, maybe a different mobo/cpu. DDR3 instead of 2. That kind of stuff. I'm kind of lazy, so modular would cut down on the mess inside the case too. Or would it be better to wait until I figure out exactly what it is I'm doing?

Not sure if this makes a huge difference..but I've got like 5x120mm fans and 2x140mm fans running too.

I lack the experience to know the answer, but now that you mentioned it, I guess switching over to a good modular PSU would be quite a pleasure seeing as you've had to put up with the non-modularness of the Rosewill Green series. And here's where I can speak from experience: when I think about my own system, I smile because it's just so clean thanks to having a modular PSU. Plus, not only do I like pushing buttons and flipping switches, but I like plugging things in as well as unplugging things.

But with your system, try to keep the PSU purchase between 500-600W. I would say 650W max. This is because of the efficiency during load, and the maximum efficiency happens at around 50% load on the PSU (generally speaking). But the actual draw on the PSU under the highest load while gaming will probably 300-350W at the most, even with the 570. But the system's idle-time will far outweigh the load-time, so a balance should be met which is why a high quality 500-600W is about perfect. But I have to admit that there are some nice 650s out there. hehe I learned all of this from some of the pages found here: http://www.overclock.net/power-suppl...-articles.html

Now, the only reason why I have the HX650 is because I couldn't find the HX450 without having to pay for international shipping (I like the color and quality of the newer HX series).

I think I'm starting to understand some of this now. I've already learned that big wad of cables in the middle of the case = bad. Fixed that with this new case and now I'm getting a bit obsessed with the cleanliness. Of those 7 fans I'll be running, only four are in right now. I can't motivate myself enough to pop 'er open and throw them in. But I figure if I've gotta do it anyway for some new stuff, I'll do it all at once.

What makes a PSU quality, exactly? You said something about a strong +12V capacity. Is that the number of rails?

Currently looking at these two. They both have two 12V rails..while the HALE only has one?

Edit: I suppose the number of rails wouldn't equal quality seeing as the HALE has one strong one. So it looks like I'm missing the point there.

The only way that I can answer this is by posting this article:

http://www.overclock.net/power-suppl...explained.html

This is linked here:

http://www.overclock.net/power-suppl...-articles.html


The capacity of the Hale's +12V is mentioned right on the specifications sticker. It says 54A as well as 648W, and that's a very strong capacity when considering the PSU has a 650W rating (more excellent info here). When a +12V's capacity is this close to the wattage rating of the PSU (regardless of whether it has a single or multi-rail), it's usually only seen on high quality units. But just like with good efficiency ratings, this isn't a sure-fire way to judge the quality of a PSU. It's just a characteristic that's usually seen in good PSUs. But now seeing as how this Hale PSU appears to be a brand new unit, it might be a really good one. I mean, it seems a few manufacturers are finally beginning to understand what we want!

But yeah, the best way I can answer the question about single rail vs. multi is by posting that article. My understanding isn't deep enough yet to answer it in my own words.

As for the modularity, if you really are obsessed with keeping your case clean and tidy, it will do wonders for it and is definitely worth spending money on.

Having said that, you already have a quality power supply, so there isn't a particular need to upgrade. It's your call really - if you want to tidy your case up even more, go for it. If you'd rather save the cash for something else, you're not going to be missing out on too much.
