will my power be enough for a 8800?

[bigdukesim]

I have a tagan 480w power supply and I am thinking of getting a 320mb 8800 xfx graphics card. I am not going to run it in sli mode, will this be enough power as I have heard so much contrasting news on this?

 

[Malazan]

I will when i can find his model.

 

[Malazan]

If the Tagan is the easycon series - yes.

GTS requires 400W and 26A across the 12V rails.

This PSU has 30A across the 12V rails.

It's tight but should run ok.

I'd buy 520W Corsair to go with it.

May I suggest the following link in case you are looking at doing any kind of overclocking? Even may be helpful if you are not planning on overclocking your system. You need to consider not just the graphics card when deciding if your psu needs replacing. Think of all peripherals that are running off of the psu as well. There is a link to a website that has a power calculator that can help you decide as well...I just don't remember where it is at.

There is also this link here in the forumz as well:

[Malazan]

That's good advice.

 

[mpjesse]

Won't hurt to try. If the system in unstable or won't start they you'll know 480W isn't enough. No sense in wasting money.

I don't at all like the idea of 4A for CPU plus HD plus opticals.

I'd buy 520W Corsair to go with it.

That's better but a 650 watt unit with 40A of +12 is more like it. I'd at least get something like the 580 watt Mushkin.

 

[mpjesse]

then write your congressman.

That don't make no sense.

I have a 500 watt Antec NeoHE and just installed the 8800 gts 320 mb. I haven't noticed any problems yet

The 8800 GTS uses 115 watts at full speed. His PSU is more than enough (by a wide margin). He probably could power 2 GTSs with that PSU

The HX520W has 40A across the three rails.

That's a joke right? He could power a GTS SLi for a few days sure but after that - its new PSU time

The recommendation for a 400w PSU with 26a on the 12v rails is for the the entire system not just the 8800GTS. 26a for the 8800GTS means that it would consume 312w of power.

Based on nVidia's estimates the 8800GTX consumes 145w of power (12.08 amps), and the 8800GTS consumes 115w of power (9.58 amps). So far no website has directly measured the amount of power drawn by the GTX and GTS. Xbitlabs.com usually measures CPU and GPU power consumption. However their custom modified motherboard that they have been using to measure GPU power consumption in the past is not compatible with the 8800 series.

Most likely yes. But it would be nice if you can provide the model number.

In fact you may able able to answer that yourself if you look at the PSU's sticker. But sometimes the sticker can be a little confusing. Best to tell us your PSU model number.

 

[bigdukesim]

my power supply is
tagan t480-u15 - easycom 24 silent modular.

the grahics cards is a xfx 320mb 8800 gts

hope this helps

 

[Malazan]

What are you talking about? It's the entire system and knowing Nvidia they are playing it safe at that.

If they say 400W and 26A will run a GTS and system - it will run a GTS and system.

You do not know what you are talking about, he does not have nearly enough across the 12V to SLI 8800GTS you cretin.

He's barely enough with that PSU for one GTS , taking into account probable poorish efficiency and degradation.

 

[Malazan]

You should be ok with that PSU, but if you can i'd upgrade, don't listen to the fool trying to tell you you can SLI GTS on this Tagan - you can't.

This site doesn't say how they arrived at their power consumptions numbers, but says the BFS 800GTS uses 168 watts at idle, and 250 under load. It also says the load usage is less than an X1900XT or a 7950GX2.

[bigdukesim]

thanks for all the help and advice but im still none the wiser.

Is it a yes or no

I cant realy afford at the moment another £70-80 pounds on a new power supply as well.

I even contacted scan who made my pc and there answer was it should/ not it would, which didnt help

Yea, I assumed as much but just went with the posted claim, not knowing if folks were OCing that card up to with obscene VCores or whatever. And regardless, 4A of headroom for the whole system is just not enough to make me comfortable. I OC the CPU on most of my machines and that will eat into that 4A as will USB peripherals, HDs added later on etc.

Yea, you'd think that two PCI-e power cables wouldn't be needed for just 145 watts. Watts up with that?

Right, like the way nvidia certified the Enermax Liberty 620 for SLI but when a single 7900GTX would not run on that power supply, nvidia told me to get a PS with more +12. As I replied to JagSX, I assumed you were accurate on your GTS amperage claim and replied in that context. I know that card is nowhere near 300 watts at stock clock but have not followed the OC specifics on it and didn't know if you were referring to an OC'ed card or what. You didn't say "the typical GTS system requires 400 watts", you said: "GTS requires 400W and 26A across the 12V rails".

Another thing, if nvidia is predicting system needs, then they need the system spec - number of HDs, number of opticals, PCI card peripherals, number of fans, case lights, front panel add-ons, etc.

 

[Lionhardt]

A lot of people overexaggerate the Amperage needed for those.
It'll work fine.

 

[Malazan]

I think your PSU will run the GTS as i have said at least twice.
