i know my question is kinda stupid, but i wanted to ask, for example if we put 125w cpu to 125w motherboard - will it not fry under 100% load? and when on cpu written 125w, is that wattage rating that is given, no matter how you stress it with stress test, it will use the same 125w? (if its not overclocked) A cpu woud be AMD Phenom II x4 965 3,4ghz 125w (HDZ965FBK4DGM) and motherboard http://www.asrock.com/mb/AMD/960GM-GS3%20FX/ Because i'm confused about wattage on the internet there's ton of that cpu usage and i dont know is it really use 125w or more. And, sorry for my bad english.

What are options from gigabyte? since my 7 years old pc with gigabyte's GA-M61VME-S2 and Athlon 64 3000+ 1.8Ghz running fine even if the champagne was spilled on the opening of it, while pc was working.And i wanted to find cheap motherboard, so should i go with 140w tdp mobo? and is there any micro ATX board because i now have micro ATX board inside case not ATX and placing atx board i need some editional screws to install witch i dont have.AHH, i forgot to mention that i need onboard gpu since i dont have a gpu yet

my budget is about 100-150$ i say because prices are different in my country
:/ and do i need buy a new case or can i use old one? there is micro atx board on it and some holes i think for other other boards and i think i need to buy theese http://www.evita.lt/en/det-12045-product.html because in the holes aren't one of those holders

i'll be choosing that Gigabyte's GA-970A-UD3 since you recommended and i think its good board with mosfet's heatsinked

 
That MB should be just fine with a 125watt CPU, the 965. The power is supplied by the PSU via the 4-pin CPU Power connector. It does not suck power from the MB. The MB has it's own power source from the PSU, the 24-pin power connector. The voltages of both will be controlled thru the BIOS.

but that would be the limit 125w cpu and 125w mobo

 
The CPU is a 125watt CPU no matter what board it is in. It get's it's power from the PSU, not the MB.

EDIT:
The power for the CPU and MB are two separate circuits. The CPU basically controls the data thru put, all through out in the MB.

And, I would probably go with that Gigabyte MB, just because it's a good one.
 


Sounds like the amps fried the voltage regulator. I doubt that a 965 would cause this problem, even if OC'd.

Gigabyte is just one step from Asus, and it has good quality boards, i think

i think of using a corsair cx series 500 or same series 600, because i looked information on good mid and high-end psu's, and these were: Antec,Seasonic and Corsair, but Antec and Seasonic price is not for my slim wallet :D

 
werner123,

I don't know the figures but I am sure that the default voltage of a FX 8350 is a lot higher that the 965. Higher voltage can translate into higher amperage easily. And I do not have a very good opinion of MSI boards. Lot's of them seem to be poorly designed as well as poorly manufactured. Cheap.

i forgot to mention that i have that asrock 960gm gs3 fx board and wanted to ask will it not blow up at testing? i want put in there cpu and rams and test if it works, and using it till i get some better board? and i'm confused about gygabite board those comment's about issues keep's me worrying :/ and there are no good microATX boards with onboard gpu, or ATX with onboard gpu?:sarcastic: onboard gpu give opportunity that if dedicated gpu fails or go dead, u can use onboard gpu

sometimes because my old pc is just one core 1,8ghz i played a lot on it with onboard gpu it been able to play nfs u2 nfs carbon even fear 2 but so laggy, i dont oveclock it since i dont know how :D planning to install new fan at the back, i use this board until i get better board, and can i use cooler's master's tx3 evo with phenom II x4 965 125w because i heard that fan is spining loudly on some youtube vidoes, and tx3 has the dual fan coniguration (push>pull) i think maybe the original termal paste is not good changing it would temps be lower? and what i think that the original fan is not in that position - the fan blowing air in heatsink but when i work with electronics when i ask on specified forum i always get answer that fan have to pull out air from heatsink...

ahh and forgot to mention that temps in my room can get at 30C at very hot day so i really need super good cooling and i always keep one side of case, and i buyed this board when i dont know about vrm's about phases and stuff, but now i think that my decision was somekind wrong and that is better to use 140w board with vrms heatsinked
