+12 V@

[toosh]

Hi guys quick question.If your Graphics card has a recommendation of +12v@26a and you ran it on +12v@22a would this effect the cards performance if so how much would it effect the running of the card.The card is an Asus 8800gts 512mb (g92).Thanks in advance

What PSU?

And 2 things will come of this:

A) Your computer wont start.

Your PSU will make a buzzing sound if on.

Unless you are using a PSU with only one 12v rail you will not need to be concerned which is why I am asking what PSU you are using.

i think if your card has a recommendation of a certain wattage and your psu delivers below that wattage, you should not use the card if you want your pc to not die a fiery death. afaik your gpu will keep trying to pull the power, the power supply will provide as much as it can, then eventually die, possibly taking other components with it. not to mention overclocking which will require even more power.

edit: ok, or what the guy above me said.

doesn't buzzing usually mean the psu is going to die?

wasnt very clear in first post.My 750w psu went pop last night so this morning in a daze i ordered a cheap Generic (made in the Ezcool factory) 500w to tide me over til end of next month.Was checking earlier and it states its single rail +12v@22a

ps Specs say my card draws 145watts on load if that helps any

Does it have more than one 12v rail with an amperage if added to the current 22a equal or exceed the 26a? if so you are fine.

I am pretty sure I have that correct, it's been a while but I am pretty sure I am correct.

Its single rail " Voltage Load +3.3V 28A; +5V 30A; +12V 22A; -12V 0.8A; +5Vsb 3.0A "

dont risk it is my advice as you said it was cheap so that imho means most likely doesnt have protections (or at least good ones) in the event you pop it.

 

[garih]

what gpu are you running?

 

[toosh]

its in my first post Asus 8800gts 512mb stock clocks

 

[KING_OF_SAND]

Yea that PSU is not enough.

 

[toosh]

Just an update:Im not even gonna tell you about the cheap psu that was delivered

needless to say it went in the bin.I now have my OCZ ZS-550W +80 ordered.Im sure the single rail 12v@38amp will be plently for my very modest Athlon64 X2 3800+ and Asus 8800gts 512mb

ps i know its not Corsair or Thermaltake or seasonic whatever but i got a mortgage,bills,3 kids etc

As long as the PSU is far more than what is needed you can settle with a cheaper PSU. Good PSUs are tested beyond what they are rated on the box. My Corsair AX850w will put out 925w of power MAX but is said to be 850w because the 925w gives enough headroom to use it on a computer needed an 850w PSU. A cheap PSU most of the times will NOT put out what is displayed on the box.

Agree 100%, alot of the higher quality manufactures like to be conservitive with their numbers. For me though the only two components in a rig i would never skimp on is the PSU and the Motherboard, why?, because those two components will always be the foundation of your rig.

Well my new OCZ ZS-550W psu installed and fully working.Ran 3dMark 06 earlier and believe it or not my score was 29 points more than with the generic 750W psu i had in it.Same computer same test.
