Source requirements for asus nvidia 9800 gtx+?

[amd125]

Hello:

That graphic as of today is nothing special. I have an acquaintance who at the time plugged it into a power supply of about 600W brand pavo… and it wouldn't start the equipment, as he didn't want to spend money on a power supply... he bought a cheap Chinese 750W one. It's better to have fewer quality watts than many watts.

In general, a good power supply is expensive, unless you buy one that is "a good result as I will indicate later" but it's not convenient to use bad power supplies. With luck the power supply will break, but with bad luck when it breaks it could give a voltage spike and break another component. This is common so I wouldn't use bad power supplies or the day it happens to you you will remember this that I tell you.

With that I tell you that watts are not important. You have to look at efficiency, the amps on the +12V line. Depending on efficiency some power supplies come with a certification.

I leave you some links of interest:

80 PLUS - Wikipedia, the free encyclopedia

Power supply: is an important a good power supply? - 80 Plus certifications

If you don't have much budget, I wouldn't buy anything less than a NOX brand one. They are not the panacea, but for what they are worth they are not bad.

For example:

Nox NX 650W NXS650 Power Supply

Cooler Master also makes decent power supplies. The Tacens brand has a name but I've heard bad experiences, I never recommend it.

Then you can look at a low-end Corsair, like this one: Corsair CX600 V2 600W Builder Series 80 Plus Bronze CP-9020048-EU Power Supply

But if I were you, I wouldn't plug that graphic, you won't be able to play modern games at decent quality and it's very power-hungry for what it will bring you. If you don't have a good power supply don't take a risk.

As amd125 rightly points out, "it's not worth using bad power supplies", because they end up giving you a much bigger headache than the possible savings you might get.

As a Hardware Enthusiasts forum, we recommend quality power supplies or at least moderately decent ones, so although the answer to your question is that a power supply with at least 32A on the +12V line(s) will work for that graphics card, it's better to buy something with a bronze certification, which not only ensures manufacturing quality, but also allows you to avoid wasting more electricity than necessary, which in the end isn't very cheap either.

A good solution could be a NOX like the one shown above, but for about 20€ more (~70$), you can get some from reliable and certified brands.

Cheers!

Well I don't know, the Tacens that I built now didn't reach 50 "leros", and the Nox in its day something similar.
That said, I don't know the threshold from which something is "expensive".

The truth is that if the power supplies last you less than six months, I would consider reviewing the electrical installation of the dwelling in question, that is not normal at all, even less so when the power supplies have 2 years of legal guarantee, no matter how bad they are...

@amd125:

That graph today is nothing special.

I disagree, I have one and the truth is that I am delighted with it and I have it in a PCIe 1.1 port, I suppose that if I connect it to a 2.0 it would perform even better in transfer.

Do you know if I would notice much of a change to port 2.0? I have thought about changing the board just for that.

It's that the board has the G31 that only supports 1.1 and the GPU is 2.0, it's the only improvement I can make.
On the other hand, I would like another board with which I can overclock to 20% just like this one and I don't know any with overclockable PCIe 2.0, in case you know any.

Currently I have an ASUS P5KPL-AM EPU with a Q8300 at 20% OC

I have thought about changing to the P5G41T and variants, for the issue of going up to 1333 MHz and DDR3, but lately they are impossible to buy.

What would you do? Thanks.

[Manuel de Sanse]

I have a 550W NOX with a 9800 GTX+ / Q8300 and it has been running for 2 years without any problems.
That is, it is connected to a 1.1 port

@Manuel:

I disagree, I have one and I'm really happy with it and I have it in a PCIe 1.1 port, I suppose that if I connect it to a 2.0 one it would perform even better in transfer.

Well I do agree and I'll show you why:

GeForce 9800 GTX+ vs Radeon HD 5850 – Performance Comparison Benchmarks @ Hardware Compare

It's a comparison between the 9800GTX+ and one of my HD 5850 (which is also old and not an extreme graphics card by any means).
The most notable fact, to name one, is that both have almost the same maximum consumption, but one performs twice as much as the other. We're talking about chips with barely a year difference between them.

The minimum I would buy is an Enermax NAXN 500W at xtremmedia for about 45€.

Do you know if I would notice much of a change to a 2.0 port? I've been thinking about changing the motherboard just for that.

On the other hand, I would like another motherboard with which I can overclock to 20% like this one and I don't know any with overclockable PCIe 2.0, in case you know any.

You won't notice any change with the Pcie with that graphics card, I know because I had a P5K premium first with a 9800GTx then with a 260GTx and they go the same in the P35 as in the P45 an MSI, just today they took the computer that had it here from my nephew and with a Q6600 and the 260 goes the same in the P5K as in the MSI P45, even maybe the Asus goes better because I overclock the CPU and the memory better.

I wouldn't change the motherboard for that graphics card, I've even put a 470 and it also goes well with PCIe 1.1, what you think about spending on a motherboard in that platform, it's more interesting to spend on a graphics card, with a 100€ graphics card you will notice much more improvement because the graphics card should be quite superior to the 9800GTx+.

That's amazing! And I was amazed with the gtx+, because if the 5850 doubles it in everything! The truth is that it surpasses it a lot, really.
The thing is that I bought it new in a liquidation sale for 20€ and maybe that's why it feels so good to have it installed, hehe. Before this one I had an HD2600XT that wasn't bad, but I gave it to my sister when I got the gtx+

Thanks for the comparison, the truth is that I'm really amazed, it's just double with one and you also have an sli, right? That's awesome!
I had thought about that option on another card with another gtx+ but seeing what's out there in ATI, the truth is that not even joking.

I'm not a fan of nvidia, but the truth is that seeing what the gpus cost I'm pretty happy with it for now, now, after that, I'll look more into ati first.
Best regards and thanks again.

Ufff…ok, well, nothing.. pci 3.0 I suppose, it was about trying to stretch the 775 more.
I read about the bus transfers 1.1 2.0 and 3.0 and thought that if I changed the bus it would transmit twice the data and perform better... in theory it should be but oh well if you tell me it doesn't I'll believe it.
By the way I see a lot of people with the Q6600 and I'm starting to doubt my Q8300, the fact that it has a higher number doesn't mean it's better, right? mine goes to 2.5 GHz (Overclocked to 3 with a 20% oc)
Just a while ago I had an E8400 overclocked by the same 20% with the asus and the truth is that I barely noticed a change from the E to the Q.
I'm starting to think that maybe I should have left the E8400 installed because I had it overclocked from 3 to 3.6 GHz.
Thanks for the help, I see that the only improvement I could make won't be worth much.
It was also about putting the Q8300 to work at 1333, which on this board runs a bit sluggish hehe.

The Q6600 of origin may be somewhat inferior to the Q8300, but what is interesting about the 6600 is that it has a 266 Bus and a multiplier of 9. In this micro, if it comes out a little decent you put an FSB of 400 with a multiplier of 8 and you have it at 3200. I am talking about the 6600 of "Go" revision because the first "B3" revision were more hot and went up less.

The problem with the Q8300 is the "low" multiplier of 7.5 with a bus of 333. This makes that with a bunch of DDR 2 800 memories the Q6600 you put it at 3200 and the Q8300 only gives you an overclock of 3000.

And as you have better memories, or the micro comes out good, you will be able to put the 6600 at 3400 (some have it at 3600 but with very good cooling and also with a voltage generally very high).

My Micro 6600 has the worst VID that exists 1.325, that is, it needs a lot of voltage to go up, and even so I have it at 3200… ;D If it were good, it would go up more. That is the difference with the 775 platform and the Bus. In general to two similar micros in frequency, for overclock it is more interesting the one that has the highest multiplier and the lowest bus. In both things the 6600 surpasses the 8300.

That yes, from stock both micros are very similar, but to speak well of the Q6600 it is enough to say that it is a micro that came out at the beginning of 2007... there is nothing, it is 7 years old, and to this day accompanied by a good graphics card it can still move most games, and at the office level, it still performs very well.

And to top it off, there are Xeon processors socket 771 that are compatible with 775 boards, depending on the chipset, and by a patch in the pins of the micro and in the Bios of the board, you admit these processors. I will not expand but these micros are selected to work in servers, so they are usually of higher quality than the normal 775, reaching some speeds of 4000... but I do not want to confuse you more than I would expand too much :wall: These micros on Ebay UK especially and USA are found thrown away in price, and I know more than one from other forums that for 40-50€ they have picked up a micro that they have put at 4000 with DDR3 memories and I can assure you that a Quadcore micro at 4000 even being old, performs like a champion.

To finish, I have tried to be clear in the explanation although brevity is not my thing. If you have understood me well, otherwise, read some overclock guide that will always be good the knowledge acquired.

Thanks, don't worry.. you can expand as much as you want! Well, I had no idea about the 771, I didn't know that. I'm going to read the guide you mentioned. Yes, mine doesn't go beyond 3.0 Ghz, and the ram is from 800 to 960, and if I put it at 1021 the q8300 stays at 2, 5 Ghz and doesn't go up from there… I get the impression that it moves slower if I increase the ram than if I increase the core. Besides, I think the ram breaks much easier than the core so I've left it at 20% and auto and it stays at 3.0 and 960 ram. I was trying to increase the core to 3.0 and the ram to 1020 (a little more than 960) but I'm not sure if it can be done, there are some voltages that the bios lets you touch but I have to read first.

Even so, it even seems to me that the pc moved faster with the E8400 increased to 3.6 Ghz than with the Q8300 increased to 3.0 Ghz both with the ram at 960. Could it be because the E has 6M and the Q only 4M cache?

The cache thing also has me confused, it's supposed to be a kind of buffer?

Thanks, I'm going to read the guide.

Best regards!
