Variety of issues after PSU install

[Marshall Hurtado]

Specs:

Windows 10 Pro 64-bit
Corsair RM750i
i7 4790K (stock)
16GB DDR3 (speccy says 666MHz? odd)
ASRock z97 Extreme4
Asus STRIX 970
250GB Samsung 850 EVO SSD
500GB Hitachi Storage
150GB WD Storage
2TB Seagate Storage
750GB Seagate Storage


I recently installed the Corsair RM750i PSU to replace my super old CX600, now I seem to have issues regarding booting, but more noticeably an issue with waking from sleep. I have my power button set to sleep, that way I just move my mouse when I wake up and everything is ready. Now though, when I move my mouse, its just a black screen although, the PC itself seems to be awake. When I press the power button again to put it back to sleep, nothing. When I press my hard reset button it takes about 20 seconds to register, then resets, and once it arrives at the lock screen the PC will freeze within another 20 seconds or so. When I installed the PSU I made sure everything was connected correctly. I was having issues with boot, something about a partition was overlapping or over a recovery partition, although I seemed to fix that by setting the Windows Boot Manager as priority #1 for boot. So now that just leaves the sleep issue, that I'm aware of. Any ideas? I'll be glad to provide more info.

Does your system clock seem to reset after you pull power from the wall? It sort of sounds like the CMOS was reset when you did the PSU replacement. Somewhat expecting the BIOS battery to need to be replaced. There should be power settings in the BIOS that pertain to sleep / wake states that deal with what you are having issues with. Look in the BIOS under Motherboard -> APCI -> wake on USB keyboard/mouse.

The best test would be to throw the old PSU in and see if it works. If it does then the new PSU might be faulty. I doubt it though as I have found that sleep causes more problems than it solves.

The time does in fact change to a different time than it actually is, MOBO is only about a year old, I do have a switch for BIOS A and B though, as well as I think a BIOS clear button, I'm not so sure (Not entirely experienced with MOBOS) . When I was having the boot error, I switched to BIOS B and managed to boot, but now I see that I'm BIOS A so I'm just as confused. Maybe I switched to B, then back to A. Must have just been an odd desperation move. I'll check on the APCI Settings, although I can still awaken the PC with both mouse and keyboard now.

UPDATE: ACPI settings had wake mouse and keyboard disabled, oddly.... considering it still worked, just with a freeze afterwards. I would imagine disabled means it wouldn't wake at all. Still confused.

I bet you are losing the settings due to the battery being drained. Would explain pretty much all the behavior.

Since they are dirt cheap pick up a CR2032 battery and replace it. Once replaced get all your ACPI settings etc set like you want then you should be good to go. The batteries normally last much longer but I have had them go out in under 2 years as well.

Selecting your answer as the Best Solution was actually a happy accident, but I'm confident that was the issue as well. Upon replacing the battery, if my issue persists I will definitely let you know.

 

[Marshall Hurtado]

MOBO battery unfortunately was NOT the issue... I really have no idea how else to troubleshoot. I don't think the PSU is defective. Everything is powered up well. Hard drives are seen. GPU and MOBO receiving power. As is everything else. I don't have the time change issue anymore however. I really don't know.


Yet another update:

I literally realized I was using an old PSU power cable from the CX600, rather than the brand new, seemingly thicker power cable for the new PSU.... I don't know much about wires, but I would imagine that a new thicker cable would be more wise than an old thinner cable...

Well to top it off, the cables could be wired differently. If you go to Corsairs website you can see that the RMx and RMi have their own cables, they are Type 4, while the CXM is a Type 3. It is surprising it even worked with the Type 3 cable.
