Need the right power supply for GTX 580
  1 / 2    
I just got a GeForce GTX 580 and I'm lacking in the power department. Since I'm new to this I don't understand the 6-pin and 8-pin PCI Express supplementary power connector business, and it says I need about 650W and my unit has only 330W total power. So I'm asking for a link to a suggestion of a power supply I should buy, and maybe direct me to a good tutorial, perhaps with pictures, on how to connect everything. Thank you in advance. If you need my other system specs just let me know.

I would get something over 750W. Go on newegg and find something to your budget....

As for connecting the cables? simple process.

1: hold the appropriate cable in your hand.
2: insert the cable into the appropriate slot.

Well I have questions, like, are the cables meant to connect directly from the card to the power unit? I'm also not even really sure which ones are which. There are 2 outlets in the side of the GTX580. I'm assuming each one gets filled. Where the other ends go I have no idea. They don't seem long enough to reach the power supply. I think I saw something about not plugging them into the motherboard. So I'm a little confused. It would be nice to have some pictures.

And, I'm not familiar with those terms.

I only dabble in this stuff once every few years so I have a question about power supplies. Are these new ones supposed to have outlets right on the side of them, or do these 6-pin and 8-pin cables hook up to other cables coming out of the power supply?

As for a guide if need be...

Install the GPU into the slot as normal.

Identify the plugs:

Find the 8-Pin PCI-e connector:

Insert it:

nice raptor! so easy a cave man could do it. but back to the questions about a new PSU (power supply unit) the card recomends what, 600W+? so if just the card takes 600w, then you'll be safe to think that all your other stuff like case fans, motherboard, overclocking (if any), and optical drives, will take a bit more power too. so if you want to not really have to worry about upgrading in a few more years, you could get a healthy 850-1200 watt unit. they range from about $100 for the "ok" ones, and upto $300-$400 for the really nice ones. i have a 1050W Enermax unit that ive never had a single pip from in 2 and a half years.

another issue is your mother board. can it handle this card? do you have the right PCI-E slot available? is it a custom built computer? or a pre fabricated unit like a Gateway or Dell? because knowing the type of mainboard you are using is just as important. help us help you!

The recommended PSU's for all these cards are requirements for a normal system with the card in, not just the card.
I'd also go 750W, I've seen a few 650W PSU's that do not have adequate 12V rails.
Personally I'd go Corsair, or any other manufacturer with a single 12V rail, they are more expensive, but there you can't hook them up wrong.

As i've stated several times, wattage is irrelavent. A 580 doesn't require any more then a 600 watt power supply. The card itself consumes 20 amps. You need a unit capable of delivering over 20A on the 12v rail reliably.

This^. Well... Pretty much! I wouldn't go as far as to say that wattage is [i]completely[/i] irrelevant, but I know what you're saying. Amperage on the +12 is definitely of greater concern, as is getting a truly high-quality unit from an established manufacturer, like Corsair, PCP&C, or Antec, to name a few. And I agree 100% that a 600w unit would be sufficient. There is currently a troubling, widespread misunderstanding of PC power supplies, and how much wattage is actually needed. While it certainly doesn't hurt to have more than you need, there's something to be said for economy. Besides, even if you're just interested in having the biggest, baddest unit you can find - for bragging rights - it's important to understand how the system works. Check this link:

[url="http://www.xbitlabs.com/articles/cases/display/system-wattage_8.html"]http://www.xbitlabs....-wattage_8.html[/url]

It's a fairly well decked-out system - nothing too extreme, but certainly no sipper - and at max load with a Core i7 and GTX 295 (which is a real power hog), it barely tops 500 watts pulled. I don't know what happened to this scene, but it seems that a couple of years ago everyone went power-crazy. All of a sudden everyone thought that if they had a quad-core proc and a high-end GPU they had to get a 1000w PSU or risk a crash. Not so.

All that said, I do second the recommendations for the Corsair 750w unit (I'm assuming TX model, not HX or AX), because it's a good price for a great power supply. Corsair ROCKS.

It came around in the G80 series, when Nvidia released their PSU calculator. They no doubt had deals with the PSU manufacturers, and when people would go see what PSU was required for their 8800GTX, it would tell people they required a minimum of 1000 watts, and going SLI required 1200 watts minimum. Now everyone buys 1200 watt PSU's for their 550w system for 500$ instead of the OCZ for 120$ that would suit them just as well.

Actually 25A on 12V rail should be enough for GTX 580

Terrible advice, need at least 22-23 amps just to run Crysis on a non-overclocked 580gtx. And that is with 0 margin of safety. I'd want 25amps capable at the bare minimum to handle any spikes and we aren't even getting into furmark consumption or anything like that...

People have disabled the voltage over protection on 570gtx's and ran furmark and have seen like 400+ watts used lol. I would want an enormous PSU for these fermi cards just to prevent any chance of stutter or performance drop or death due to slow brown out.

I'd say 650w PSU bare minimum for 570gtx and 750w for 580gtx (preferably single rail) if you actually want to have some margin of safety and no chance of stutter etc.

Congratulations.

You've earned the "Flamer with no idea what he's talking about achievement"! Not only did your conclusion have the same result mine did, but you points don't even support your premise.

1) What half decent power supply provides less then 30 amps? The card itself, only requires 20A at full wack, possibly 2-3 amps more for benchmarking. I've written a guide to power management and power supplies. These numbers come from Guru3D's own testing station measuring power use from the wall socket itself.

2) A difference of 2 Amps can easily account for a PSU of lower quality and/or aged components.

3) Furmark is designed to literally kill GPU's...what program is an average consumer, no, even an enthusiast consumer going to run that would require the overvolt protection on their video cards disabled?

Feel free to waste money on "an enormous PSU for these fermi cards just to prevent any chance of stutter or performance drop or death due to slow brown out." if you want to. The more educated can save money and pick up a good high quality 600-750 from Corsair, Enermax, or OCZ that could do them for the life span a half a dozen builds+...

Do not flame unless you have substantial reasons why someone else's opinion should be taken with a grain of salt...or, at the very least...learn to be polite about it so it encourages positive discussion instead of telling someone their advice is terrible...

Terrible advice, need at least 22-23 amps just to run Crysis on a non-overclocked 580gtx. And that is with 0 margin of safety. I'd want 25amps capable at the bare minimum to handle any spikes and we aren't even getting into furmark consumption or anything like that...



People have disabled the voltage over protection on 570gtx's and ran furmark and have seen like 400+ watts used lol. I would want an enormous PSU for these fermi cards just to prevent any chance of stutter or performance drop or death due to slow brown out.



I'd say 650w PSU bare minimum for 570gtx and 750w for 580gtx (preferably single rail) if you actually want to have some margin of safety and no chance of stutter etc.
