PSU can't start
- Thread starter dasos
- Start date
Two of them, one with a HD7750 for a guys 9 year old son. Used this power supply.

The other was for a older couple and used a HD6570, would have just done them a FM2 build now, but just FM1 was out then and was a deadend socket. I used this one.

They only one here that is not "well informed", is YOU. Please go do some homework before you start stating false information and make an ass out of yourself. Oh, you already did.
Edit: w/e = Whatever.

Hey boys... Get informed yourselves by just reading the manual:
To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or higher). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

We're not debating rather the manual say's this or that. Just saying that you 'CAN' run that MoBo (Motherboard) with a PSU (Power Supply Unite) less then 500w.
What are u talking about? U make no sense.
I just informed u what the manual says.
I saw myself that its true. I tried 2 psu's with <500W and mobo couldnt start normaly. Then I returned back mobo and took another one. Same problem.
Well boy, I m afraid you need to apologize.

Well most of the point is a board itself uses very little wattage. Plus a board has no way on knowing what power supply is hooked up to it. A power supply only puts out the watts thats required of it.
Say you have a 400W and a 1000W power supply. Your computer pulls at idle 175W, on booting it might take slightly more 200W, then after loading it will settle down back to 175W. The computer gets the same wattage to it by either the 400 or 1000W supply. A supply doesnt load up the computer with what ever wattage it has, the supply puts out whatever wattage the computer needs. So from the above, the computer has no way of know what size power supply is hooked up to it.
Your quote from the manual above does not mean what you think it does.

My intentions is not to be rude or mean in anyway, but trying to inform you that it doesn't need a 500w PSU to function is like talking to a wall.
Edit: I apologize for coming off as rude or hurtful.
Edit:
Just through a 500w PSU in there and be done with it then.

My dear... its not me who says that. Its Gigabyte.
So if u have any objectionss tell them to Gigabyte. I cannot do something.
If u really think that this mobo does not need a 500W psu, then why I cant run it with a well working psu of 450W?
Why a second mobo cant run either?

You have conflated what the board manual says and turned in into something else.
For a start, the above statement is always true, for every board.
Secondly, lets go through the statement.
1. To meet expansion requirements.
This is not the motherboard. This is things like graphics cards etc. This is true, and true for all motherboards.
2. Recommended power supply.
Simply recommended, not essential. Very much a recommendation. Considering there are 500W power supplies that have 12A on the 12V rail and other that have 40A (dependant on quality), if it was a technical requirement to have a certain power, the manufactuer would HAVE to specify amperage, not wattage.
3. The fact that an underpowered PSU can lead to a unstable system (ie it turns on but is unstable), by itself means that you're wrong. Also, this is ALWAYS the case. An underpowered system = instability.
Finally, you have read a simple recommendation for a power supply that relates to the EXPANSION component power requirements and decided that somehow that meant the motherboard doesn't work without a 500W PSU????
False.
Finally, a classic circular argument.
I am right because I cannot prove using my same logic that I am wrong.
Lol.
The other possibility is that the mobo is buggered, and not providing a 'good' signal to the PSU to turn on. OR the PSU is buggered, or the a multitude of other things. Benchtest your system properly.

No, I checked it myself. In many ways. For days. Plz read the whole thread.
Come in my position. What would u do, what would u think?
I guess that if I was in your position, I would say exactly the same things with you.
PS. Manual is clear. Says--> If a power supply is used that does not provide the required power(500W), the result can lead to an unstable or unbootable system.
Unfortunately, I saw that after I got second ga 970a ud3-not normaly bootable too.

Ok, whatever. There are so many technical reasons as to why you're wrong, and I too have read the quoted manual section, and it does not mean what you have deducted.
I would suggest your PSU is stuffed, that is all. Or you haven't connected the 12V CPU PSU cable to the mobo.

Hey, its not me who is wrong, its Gigabyte, if you are right.
Tell them to correct their manual then.
About my PSU, as I said I tried another. Both PSU's work fine in their systems.
(lol, so u think I didnt connect the 12v... Boy, I made connections for days. I tried everything before I return it back).

lol, be sure for this.
I have 10 years of pc experience. Many mobos have passed from my hands.
But u really think that when Gigabyte says To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or higher). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.
means something different than that?...

He seems to over look/ignore my post of using the same board with a Corsair CX430 and a Seasonic S12II 430W.
