jrdnlc Posted February 4, 2017 Author Share Posted February 4, 2017 I have an extra 600w psu but i can't find the 8-pin cpu connector just one. Can i still test it out like that by just powering one cpu or do i need both connectors? EDIT: Tried it, same results. I'm convinced now that the MB is dead Quote Link to comment
garycase Posted February 5, 2017 Share Posted February 5, 2017 I think you'd have to power both CPU's for the motherboard to function, so testing it with only one CPU having the extra power doesn't really confirm anything. A PSU tester will at least confirm that the CPU output is good on all of the "rails" (different power outputs). I agree it's more likely the board is dead, but either is possible, and it's worth a bit of time to confirm that before sending the motherboard in for repair. Quote Link to comment
jrdnlc Posted February 7, 2017 Author Share Posted February 7, 2017 Tested the MB with the tester that I ordered from Amazon and it's in working condition. Supermicro approved the RMA and the MB was shipped yesterday. Lets see what they say. Fingers crossed Quote Link to comment
jrdnlc Posted February 13, 2017 Author Share Posted February 13, 2017 So my motherboard arrives back tomorrow. Supermicro didn't charge me anything for repairs so i decided to email them. Got a response today saying that nothing is wrong with the MB and it booted up just fine with both cpu sockets populated. Can it be the psu even if the tester shows it's working properly?

ashman70 Posted February 13, 2017 Share Posted February 13, 2017 It could be the PS, it could be something still shorting the board. Did you send them your RAM? Outside of your RAM and CPU, which I doubt are the problem there isn't much else really. Quote Link to comment

I took the board out of the chassis and it gave me same problem. Quote Link to comment
ashman70 Posted February 13, 2017 Share Posted February 13, 2017 So when you get the board back, this is what I'd do, sit it on a small box on top of the anti static bag its in. Connect the power supply to it and see if it powers up, if it does, put in one CPU and some RAM ( not all) connect video and see what happens, if that works add the other CPU and all the RAM and see what happens.

garycase Posted February 13, 2017 Share Posted February 13, 2017 ... Can it be the psu even if the tester shows it's working properly? Yes. The inexpensive testers simply check that each of the voltage buses are generating the correct voltage ... but they do NOT test under load, so they are just a quick "sanity check" to see if the voltages are present ... NOT a thorough test. If they show a PSU is bad, then it's bad; but if they show that it's good, it just means the voltages are present ... there could still be problems. You can get load-based testers, but they cost a LOT more. Best way to really test whether the PSU is a problem is to use a different "known good" power supply. Quote Link to comment

ashman70 Posted February 13, 2017 Share Posted February 13, 2017 Umm I've done it hundreds of times with many different motherboards and never ever had a problem. Perhaps you can explain why you think it might cause damage? Quote Link to comment

ashman70 Posted February 13, 2017 Share Posted February 13, 2017 'They' being what ? And can you expand upon your reasoning please? Quote Link to comment
garycase Posted February 13, 2017 Share Posted February 13, 2017 Note that Ashman suggested sitting the board "... on a small box on top of the anti static bag ..." => NOT directly on the bag. That's fine -- the anti-static bag helps protect against static discharge and the box "holds" the board. Personally, I use one of these, which is a much better way to test boards out of the case: https://www.newegg.com/Product/Product.aspx?Item=N82E16811353001 Quote Link to comment
saarg Posted February 13, 2017 Share Posted February 13, 2017 'They' being what ? And can you expand upon your reasoning please? We spoke about antistatic bags, so they means antistatic bag. There is enough hits on google on antistatic bags, so I'll leave you to google it instead of me repeating what is already out there Quote Link to comment

I already tried booting it up without ram or cou. My mb needs both cpu's to post. Feel free to read precious replies to see what exactly did. Quote Link to comment
ashman70 Posted February 13, 2017 Share Posted February 13, 2017 Thanks for clarifying Gary, thats what I mean, board on top of box, box on top of antistatic bag. Quote Link to comment

jrdnlc Posted February 13, 2017 Author Share Posted February 13, 2017 Should I get a Seasonic or Corsair PSU? Which do you guys recommend? Quote Link to comment

jrdnlc Posted February 13, 2017 Author Share Posted February 13, 2017 Would 850w be enough for two gpu's and 20 wd red drives? Quote Link to comment
garycase Posted February 13, 2017 Share Posted February 13, 2017 Note that it MAY not be the PSU => as I'm sure you recall, you DID short something to ground by having the extra standoff ... and if it didn't damage the board, then it damaged something else. Hopefully it IS the PSU and not one of your CPU's, but the only real way to know is to test the alternatives one-at-a-time. A new PSU is a good first step => be sure to buy a quality unit with a pair of 8-pin EPS-12v connections -- e.g. something like this: https://www.newegg.com/Product/Product.aspx?item=N82E16817139083 Quote Link to comment
