PSU for GTX 760?
2013-07-06, 06:35 AM
#1
I’m looking to purchase an NVIDIA GTX 760 as an upgrade to my current Radeon HD 6670, however I only have a 500W generic PSU and therefore will have to upgrade the PSU also.
I am temporarily away from the desktop I want to upgrade so I can’t give full detailed specs., however it has an i5 2400 CPU @ 3.10GHz and 8GB of DDR3 RAM. If I were to add in the GTX 760, what wattage PSU would I need to make sure I run into absolutely no heat issues in the future? I was thinking 1000W but that may be a bit of an overkill and I could probably save quite a bit of money by getting one with less wattage.
Also, what brand should I get for both the GPU and PSU? I was thinking this Asus 760 (http://www.newegg.ca/Product/Product…82E16814121775) and was thinking I should get a Corsair PSU.
Also, anything else I should keep in mind/verify before purchasing?
Thanks in advance!

750w — 850w should cover it
I imagine you will upgrade CPU in the future aswell, so this is a save area.![]()

I literally just got in a new video card, PSU, and SSD upgrade and finished getting it all set up about 20 minutes ago.
I went from a GTX 470 SC to a GTX 770 OC, Power supply went from 550 to 850W (this). It was a lot larger than expected, about 20% larger than my old PSU but it fit well enough in my case.The price may be higher than what you are looking for but damn this thing is sexy and 850W is more than plenty for a long time. For the card you have in mind you probably only need a 650 or 700W but you can probably go a little higher without spending too much more. Doing so will give you more «future proofing» in case you want to use the same PSU in a new PC later down the road.
Biggest perk though, the PSU is super quiet. When you aren’t sucking a lot of juice this power supply is virtually silent.

No no no.
Just no.
You do NOT need over 600w. Even a decent 450 will do. Your 500 is most likely fine, unless it’s utter trash.

Do you mind providing the brand/model? You can find this information located on a sticker on the PSU itself.
Unless it’s some fireworks hardware, 500w is plenty for your setup. You could easily run that setup on a good quality 450w PSU.
The only time you’ll ever need more than a 550w PSU is with SLI. That includes a 690/7990 (though you could likely run these two off a good quality 550w but if you overclock it and depending on your CPU it might get a bit close to the output rating).

550w, anything above that is overkill unless you are planning on going SLI and doing some heavy overclocking.
EDIT — as already mentioned, your 500w PSU could very well be more then adequate as long as it is not complete garbage.

Why does everybody like going the bare minimum with PSUs? Its good to give a little headroom.

You could quad sli with this xD
Good quality 550w would be the right spot, you could get even lower. Pick a 80+ Bronze certified from a reputable brand and you are good to go

550W is little headroom, 750-850W is totally overdoing it. Whole modern gaming computer with i5-3570k or 4670k and GTX760 uses only about 300W of power, maybe 400W when everything overclocked, so how much headroom you actually need for it?

Thanks for the replies everyone! So I’m happy to hear that I may not even need to upgrade my PSU! Unfortunately as I’m away from the computer I can’t see what brand the PSU is, however I just might have a list of the specifications on my phone from back when I was building the computer . Currently I’m a little too busy to go searching for it through the file system but I will attempt to get that information later today and will post it here.
Thanks again everybody!

Well… You said «generic 500W» … If it’s some chinese no-name shit those could be 300W in reality and not cutting it with the new hardware. That’s the main difference between cheap and quality PSU. Quality PSU has continuous wattage it states on the box while cheap PSU can deal only with peak wattage stated on the box and maybe not even that much.

Because people often misunderstand how computers work, simply put.
What headroom do you want? Room for a better CPU? CPU’s aren’t going up in power.
Room for a newer GPU? GPU’s aren’t going up in power.
A larger power supply of good quality is actually WORSE because power supplies often become slightly less efficient at lower loads.
A 500w PSU will actually use LESS power than an 800w in the same computer. Not much, but still. Why are you paying more money for the opportunity to.. pay more money.
The only ‘headroom’ needed is to consider SLI, and SLI just isn’t done much.

Even a high quality 450W will be more than fine for that setup.
There’s little reason to get a 750W or above nowadays, unless you were pushing all your components to the max by overclocking them and running multi high-end GPU’s etc. We’ve left the old days of where 650W was a bare minimum or the average requirement for PSU’s, as graphics cards back then were just so power hungry.
Sure, headroom is important, but be realistic about it — are you to planning on running 2 GTX 760’s in the future? Also, your i5 sandy bridge consumes very little power, especially since it’s not an unlocked model that has been further overclocked. I’d like to recommend this one: http://www.newegg.ca/Product/Product…82E16817151124
Ok, so you might think to yourself — doesn’t that look overpriced for only 450W? Could be, but it’s definitely not a low quality product as it’s from one of the most well reputed manufacturers that have earned the trust of many other companies, including Corsair, XFX, OCZ (PC Power & Cooling), Antec and more recently, Cooler Master.
I personally wouldn’t mind spending a bit more for a good quality PSU any way, and the fact that it’s a gold certified is a nice plus.
EDIT: Nice, just noticed that there’s a 10% off deal on it.

Not really sure what the point of your post is but cool for you, you got a refurbished OCZ
1000W is massive overkill, besides what’s already been mentioned in here already.

I’m sure the guys at Microcenter danced a jig to get that thing off their hands, even at a cost loss.

Oh god the image that put into my head is pure awesome-ness.
A 500-550w 80plus bronze will work just fine, though I do like the one Drakeos posted. 80plus gold for ~$70. mmmmm
If you must insist on using a non-sanctioned sitting apparatus, please consider the tensile strength
of the materials present in the object in question in comparison to your own mass volumetric density.
In other words, stop breaking shit with your fat ass.+My awesomely kinda-good computer setup+

That means it’s 90% certainly some no-name chinese shit that is actually 300-350W PSU, nowhere near 500W.

Gigabyte GeForce GTX 760 2GB Review (Page 12 of 13)
Page 12 — Power Usage, Temperature, Noise
Using a wall power measurement device, I noted down the total system power consumption with the Gigabyte GeForce GTX 760 2GB installed. Do keep in mind this includes every component of the system — including power supply efficiency loss — and not just the graphics card only. Also, the load conditions cannot be directly compared against this base value, since the entire system is under load, and as such the CPU will also contribute to the increased power usage to some extent. With that in mind, the Gigabyte GeForce GTX 760 2GB’s power consumption reached a maximum of 271W load from 85W idle — a difference of 186W.
Gigabyte likes to promote their lower RDS(on) MOSFETs, quality solid capacitors, and low power loss ferrite core design. In the past, I have seen a difference in power consumption as much as 10W against reference cards with regular components. The above results were obtained when running Furmark’s stress test, and your graphics card is not likely to see any higher loads — especially under normal usage. To be honest, you are not going to get anywhere near this under intense gaming sessions, so really — this is just for interest’s sake, haha.
For the purpose of this review, I left the fan on default settings, so its speed is allowed to vary accordingly with temperature. I also wanted to see what the card is capable of doing inside my low airflow chassis configuration. Most people should get better results in real life than our hot running test bench environment. With that in mind, I left the stock paste intact for testing before taking it apart for the photo session on Page 3.
Its thermal interface material was applied properly from the factory, and I have noticed little performance difference between what Gigabyte has included with the card and my Noctua NT-h2 paste applied afterwards. Secondly, even under our intense Furmark load tests, the Gigabyte GeForce GTX 760 2GB peaked out at only 63c; a figure that is simply amazing. It is important to point out this is the worst case scenario — you will not hit this temperature under normal gaming sessions. Most cases should have better airflow than my configuration anyway.
As far as noise is concerned, while this is very subjective, I am quite a picky person on noise, and the loudest component in my entire system is probably my Noctua ultra low noise fans — and they are not loud at all. In my opinion, there is no objective measurement of noise, as measuring sound pressure level is often impractical, because human ears are more sensitive to some frequencies than others. On a scale from 0-10 where 0 is silent and 10 is the loudest, I would rate the Gigabyte GeForce GTX 760 2GB to be at 2.
0/10 at 20% fan speed. 20% is the default fan speed during idle. You probably can’t hear it until it goes above 30%, even for the most picky of all silent PC enthusiasts. The fan will kick up to at full load, unless set otherwise. On a scale from 0-10, where 0 is silent and 10 is the loudest, I would rate the Gigabyte GeForce GTX 760 2GB to be at 7.0/10 at 100% fan speed. Seriously, it is loud at that speed — but at least the fan runs smoothly. If you want your card to be appropriate in a quiet PC configuration, keep the fan running at or below 30%. Once you bump it past that magic mark, you are going to hear it. That said, as with all Gigabyte WindForce cards I have used in the past, when you are not gaming, it is extremely quiet. Silent computing guys like yours truly will be pleased.

Wind power. Beaufort scale
Beaufort scale is a conditional scale for visual assessment of wind strength (speed) in points based on its effect on ground objects or sea waves. It was developed by the English Admiral F. Beaufort in 1806 and at first was used only by him. In 1874, the Standing Committee of the First Meteorological Congress adopted the Beaufort scale for use in international synoptic practice. In subsequent years, the scale has changed and refined. The Beaufort scale is widely used in marine navigation.

Beaufort ground wind strength |
||||
| Beaufort points | Verbal definition of wind force | Wind speed, m/s | Wind action | |
| land | at sea | |||
| 0 | Calm | 0-0. 2 |
Calm. Smoke rises vertically | Mirror-smooth sea |
| 1 | Silent | 0.3-1.5 | The direction of the wind can be seen from the drift of the smoke, but not from the wind vane | Ripples, no foam on the ridges |
| 2 | Light | 1.6-3.3 | The movement of the wind is felt by the face, the leaves rustle, the weather vane is set in motion | Short waves, crests do not tip over and appear glassy |
| 3 | Weak | 3.4-5.4 | Leaves and thin branches of trees sway all the time, the wind blows the top flags | Short, well defined waves. The combs tip over and form a glassy foam, occasionally small white lambs form |
| 4 | Moderate | 5. 5-7.9 |
The wind raises dust and papers, sets in motion the thin branches of trees | The waves are elongated, white lambs are visible in many places |
| 5 | Fresh | 8.0-10.7 | Thin tree trunks sway, crested waves appear on the water | Well developed in length, but not very large waves, white lambs are visible everywhere (in some cases splashes form) |
| 6 | Strong | 10.8-13.8 | Thick boughs of trees sway, telegraph wires hum | Large waves begin to form. White foamy ridges occupy large areas (probable splashing) |
| 7 | Strong | 13.9-17.1 | Tree trunks sway, it is difficult to go against the wind | Waves pile up, crests break, foam falls in stripes downwind |
| 8 | Very strong | 17. 2-20.7 |
The wind breaks the branches of trees, it is very difficult to go against the wind | Moderately high long waves. On the edges of the ridges, spray begins to take off. Foam strips lay down in rows in the direction of the wind |
| 9 | Storm | 20.8-24.4 | Minor damage; wind blows off smoke domes and roof tiles | High waves. Foam in wide dense stripes lays down in the wind. The crests of the waves begin to capsize and crumble into spray that impairs visibility |
| 10 | Strong storm | 24.5-28.4 | Significant destruction of buildings, trees uprooted. Rare on land | Very high waves with long downward curved crests. The resulting foam is blown by the wind in large flakes in the form of thick white stripes.
