Problem napajanje Gigabyte GA-MA770T-UD3P

Tako.. racunalnik noce zalawfat.
Problem: maticna ima2 power conectorja. 1x 2x4 in 1x 2x12.
Jaz imam na napajalniku 2x12 (10+2) in 2x4 (2+2).
Če priklopim samo 2x12 se sistem zažene in ne gre nikamor.. pač samo napajanje gre čez matično. Če priklopim še 2x4 pa mi začne piskat speaker. (kar naj bi pomenilo power prblem)
Prebral sem navodila in piše:
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not
connected, the computer will not start.
• To meet expansion requirements, it is recommended that a power supply that can withstand
high power consumption be used (500W or greater). If a power supply is used that does not
provide the required power, the result can lead to an unstable or unbootable system.
• The power connectors are compatible with power supplies with 2x2 12V and 2x10 power
connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector,
remove the protective covers from the 12V power connector and the main power connector on
the motherboard. Do not insert the power supply cables into pins under the protective covers
when using a power supply providing a 2x2 12V and a 2x10 power connector.
