Rasputine Posted January 23, 2014 Share Posted January 23, 2014 God, I hate intermittent errors! Please some clues, this is driving me mad: Gigabyte H87M-HD3 Corsair CMZ8GX3M2A1600C9 Vengeance 8GB (2x4GB) DDR3 1600 Mhz CL9 XMP CIT 450w Gold 12CM Silent Atx Power Supply Seems like 1 in 5 times, it fails to wake up from sleep mode and I hear the MB classic beep beep beep signaling memory failure. "Seems" like it only does this with both memory sticks and at 1600 Mhz (at 1333 Mhz doesn't fail). I have tested each stick separately and it seems none fails. Is this a power issue? (BTW, I only used 4 pins on the ATX 12v 2x4 pins connector, as the power source has only a 4 pin and 6 pin cable). THANKS! I bought this in Amazon and don't know what to return back!

If your board has an 8 pin CPU connector you need to use an 8 pin connector from the PSU. These newer Z87/H87 MOBOs are VERY VERY finicky about power.

Rasputine Posted January 23, 2014 Author Share Posted January 23, 2014 Thanks Yellowbird It`s this one: http://www.amazon.co.uk/450w-Gold-Silent-Power-Supply/dp/B000O38OPG about the 8 pin, the Gigabyte manual explicitly says: Connect the 4 pin cable OR the 8 pin for other PSUs Maybe I could cut the 6 pin into 4 + 2 .... ? Is that OK? Or return the PSU? Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 23, 2014 Share Posted January 23, 2014 NO! Do not use any other connector, the pin outs are different and you will damage your system. My suggestion is to buy a proper brand name PSU that is current and tested/verified to work with your chipset. You need a proper 8 pin connector.

Rasputine Posted January 23, 2014 Author Share Posted January 23, 2014 How about a 4 to 8 pin adapter? Its all 12v anyway Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 23, 2014 Share Posted January 23, 2014 It's your choice but I would not use that PSU with any modern MOBO and especially an *87 chipset. They are VERY picky about the power supply. NO! Do not use any other connector, the pin outs are different and you will damage your system. My suggestion is to buy a proper brand name PSU that is current and tested/verified to work with your chipset. You need a proper 8 pin connector.

Rasputine Posted February 2, 2014 Author Share Posted February 2, 2014 It's an Haswell compatibly issue. Link to comment Share on other sites More sharing options...
