If you're trying to max games in three years or at 1440p, 2gb of VRAM won't get you far.

~430/450w for single 770/280x + haswell

Then I guess I was really overthinking, as looniam said, that I'm doing... I won't repent saving 12€.... it's incredible what people do for saving some money, eh? tongue.gif

"Overthinker", this adjective suits me very well!!

Everything he has said still applies.

I never said that 650W would be insufficient with benchmarking. Ever. Besides, and again, the kind of PSUs we are talking about are able to easily deliver their rated wattage 24/7. So, the kind of 650W PSUs that we are talking about would be just fine if you were pulling 650W from it 24/7. They'd be hot, yes, but they'd be fine. That's what they were designed for.

 

Yes, a PEAK-rated PSU would not be good if you were to pull 650W from it because it would only last a few seconds at the most before it shut down on you in order to protect itself (that is, if you had a decent peak-rated PSU. Remember that). However, we are not dealing with or talking about peak-rated PSUs. None of the PSUs that we recommend are peak-rated. They are all continuous-rated.

 

Besides, benchmarking is not going to pull more power than gaming unless you can find benchmarking software that will put both the CPU and  your video card under full load at the same time, just like Folding on both the CPU and the video card at the same time would do. Even then, you'd still have way more than enough power just as I thought I illustrated already.

If you're not going to do SLI, then all you need is a good quality-made 450W PSU. Period.

I don't even think I'm going to do SLI, also because that would happen like in 3 years from now, not earlier! I just wanted to be as future-proof as it's wise to do. The thing is, I'm not wise, this is my first build, and it's not even going to be a full one, just a "zombie" upgrade, a good gaming machine in a small 2007 aluminum chassis and a 2009 video card....

So, I'll ask once more, as if I wasn't enough redundant until now: is a 750W PSU going to be of ANY help/advantage with my complete build?

 

Absolutely not. No way. No. If you're going to have just one video card, then all you need is a good quality-made 450W PSU, and that would be more than enough.

 

Will you ever increase the voltage of your video card?

I think I'll use the video card brand's own software to tune it (for example, if i end up buying the asus gtx 770, i'd use their program). I don't think I'd do that manually but it could happen.
Sorry to be that redundant and sturdy. It's hard to go against my beliefs and people's advises... a guy i know has built his pc with a single gtx 770 and a 4770k, and he chose an enermax 800W PSU, so you'll know what he told me about the topic, for example the thing I already knew that capacitors would start to decrease in performance, but that should be a non-issue with this kind of PSUs.
It will last for at least 4 years at avg. 10 hours/day at (relatively) high load, right? What about noise?

I wouldn't touch ASUS' software. It's crap.

 

Anyway, most people do not know what they're talking about when it comes to PSUs, including that guy. He's wrong. Absolutely wrong. He wasted his money when he could have been just fine for 5-7 years or even slightly more with a good quality-made 450W PSU. The capacitors in good quality-made PSUs, particularly the ones that I recommend, are so good that it's a non-issue. Capacitor aging and degradation is only an issue of the capacitors aren't very good. Too many people like that guy think they're an expert because they know a couple of technical things like that, but a little bit of knowledge is a dangerous thing. FULL knowledge is what's needed, and he doesn't have it. I'm sorry to cut him down so much like this, but it's hard to fight these people when they insist that they're right. The problem is, they're partially right, but it doesn't apply to good quality-made PSUs.

 

So yes, it will last very easily. However, why would it be 10 hours per day at a relatively high load? Did I forget something? Are you going to be Folding, Mining, or gaming? I'm involved in way too many threads!

I may have overshot the average, but in practice I'm on my pc from 6 to 10 hours a day (it can happen when I'm on vacation for example). My aim is to have a pc that's fully unleashed and able to do 360° tasks, so one day I can say "I'll try this thing on my PC!", with all the risks that come with this kind of choice. Think of it as a shaolin monk: it must be able to meditate and then to fight, all with harmony and no strain (insane level increasing), with harmony I mean all the components are used in a balanced way, i'm trying to have no overused or strained components.

All the prose apart, I'm going to be gaming a lot, and work a lot with it.

Is GBT video card software any better?

If gaming is the most demanding thing that you'll be doing, then it will easily last longer than 4 years.

 

I would just use Afterburner or whatever else may be recommended. There's nothing wrong with not using the manufacturer's software.

I'm on my system for like 10 hours a day a lot, but it's idle for like 3 quarters of that the typical time. Watching videos, writing on forums, skype etc is basically zero on the PSU load, the only time load is major is playing some of the games i play that max GPU, so that's like you'd have to be actually ingame, playing some GPU bound game for 10 hours that also loads cpu quite a bit, just to get your average draw to be like 300w

Thank you Cyro, that's accurate for me too.

Today I've looked up some lower power 80+ Gold PSU, and I've found out 3 products at a very interesting price:
1. Seasonic S12G 450W (76,90€)
2. Corsair CS650M 650W (82,20€)
3. CM V550 550W (85,80€)

There are also some other outstanding PSU at the store, searching "PSU 80+ gold" and sorting by price comes out with this: http://www.e-key.it/catalog.aspx?search=alimentatore+80++gold (click "descrizione prodotto" and choose "prezzo crescente" to have them sorted by price ascending)
I hope you can help me choose between one of those, or the XFX 80+ Bronze one! I didn't know there were gold PSU at that price, but some of you said the 80+ Gold is only a market thing... is it?
