Stop recommending 650W-850W power supplies for single card systems - Page 24  

post #231 of 286
I would lile it if the P/S threads did contain the technical details that the OP(Phaedrus) is asking if others know about, but they do not so how is the question relevant? Phaedrus does not say "this is a poor P/S due to its use of a outdated or inadaquated voltage regulation technique, or this P/S uses a transformer that has shown to have a failure induced in fabrication, or "this P/S under examination shows a high number of poor solder joints". When Phaedrus himsel gives the thumbs down to a P/S it is not explained why or when the thumbs up is given it is not explained why. It is simply, "I am the P/S moderator and this is my show" and that is it.

It is the same way when a P/S gets the OK to be used. It is simply "the wattage delivered is not inadaquate or excessive so I give this P/S the OK to be used in your system. What I am saying is I would like a good bit more detailed information about the why's and why not's about the P/S besides wattage.When I say "more" I mean more that saying "this is simply a re-branded system that we have been seeing from company xyz for the last 3 years. These type explainations also leave me wanting more in terms of an explaination.

I always go with a 650W or larger PSU since the price difference is just minimal. Do I want a 500W PSU for 60€ which will be inadequate if some day I went mad and bought a second high end GPU (this might happen since I got a job now lulz) or do I want a 650W PSU for 80€ which will be adequate for me until it eventually dies. I'm loving my HX650W. I just bought a TX650W V2 for my mining rig and it will include two 6950's overclocked and unlocked. If the PSU can pull it off I think I've made my point, no reason to buy smaller unit to save tiny amount of money.

Even still Phaedrus is right, if one isn't going to upgrade to SLI/Crossfire then going over 500W (talking about quality PSUs) is waste of money.

My sig rig is on a 630W I believe, and it's about as hungry a single-card rig as you can find.

People tend to overkill the PSU because there are so many lower quality units around that people think are high quality. They aren't, so the recommendation becomes more watts instead of more quality.

You get what you pay for with PSUs. I'd rather have a $150 630W than a $130 850W any day.

I run similar setup just with a Q9550 @ 4GHz and even more power hungry GTX480 @ 840/1025Mhz on a PSU with 43A on a 12V+ rail (516W)..

I have thrown everything on it from Furmark,Games,3Dmark 11 to OCCT PSU Stress Test and never had a glitch..

CHEERS..

Is an Antec TruePower Quatro 850w enough for tri-fire 6970s?

Originally got it so I could CF at a later date, now just curious if I have the power for 3 6970s or just 2. *Since some sites claim they pull 300w ea.*

Should be fine, those cards only use about 130-150W each under full load. The 300W figure you've seen was probably for the whole computer under load with that GPU installed.

Tri-6970s and your system won't pull more than 700W.

But if they're using an HD6950 or GTS450 or HD6850 and state that they aren't going to SLI/Crossfire, then recommending a 650W or more is wasting their money.

And before saying "they may want to SLI/Crossfire later", first check and make sure that they have a dual slot motherboard in the first place. rolleyes.gif

Ignorance is bliss. I like corsair so that is what I compared, the marginal cost is $10 to $15 more (provided you dont buy a very cheap psu) for and extra 150w. Its about head room. You dont buy a 400w psu and pull 390 from it, you will wear it out. For $20 more you can have something with 650w and good head room so it runs cool. I have gone through my share of psus and running 350w off a 500w psu gets hot quick. I will say the people buying 1200w psus are going overboard.

I was pulling well over 450-480W on a 500W Antec EarthWatts for several months when I had my 4870X2 which as we all know gulps power like mad. The PSU was fine, didn't run any louder or particularly hotter than normal.

Provided you have a reputable PSU, running it within its limits will not magically kill it more quickly.

Love where this thread is going. From agreeing with Phaedrus, to asking if PSU is enough for x build, to a pissing contest.
