    Default Advice on new PSU

    Hi,

    I'd like to replace my 7 year old PSU as I've been noticing the PC has been a bit flaky lately with random restarts etc. and don't want to risk any components getting damaged. Here are my specs -

    - i5 2500K @ 4 GHz
    - ASUS P8 Z68-V GEN3
    - 2 x 4GB Corsair DDR3 1600Mhz
    - MSI R9 390 GAMING 8G
    - 2 x 7200 RPM SATA HDDs
    - 1 x SATA SSD
    - 2 x 180mm fans

    I might also upgrade in the future to i7 6700K (with similar overclock) & 1070.

    My location is Australia and these are the shops I usually go to:

    PCCG - pccasegear.com
    PLE - ple.com.au
    Skycomp - skycomp.com.au

    Could you please recommend me some PSUs? I am looking for something reliable (and preferably modular) that will last 5+ years without skipping a beat.

    Thanks!

    Look for a corsair RMx 550/650W or EVGA G2/G3 of the same size

    Those random restarts are because of your PSU? Which one do you currently use?

    Possibly - there are a few other weird things that have started happening in the past week as well:

    - Both HDDs not being picked up by the O/S
    - Really long POST times (will sit on the ASUS splash screen for a couple mins)
    - Really long Windows startup and shutdown times (over 10 minutes) when no updates are being installed

    My current PSU is a Corsair HX650W

    To me, that sounds more like a motherboard issue than a power supply issue

    Well, maybe the HDD itself is the issue here? These symptoms seem to match such hypothesis.
    Xeon X3440 @3,1GHz + GTX660 + 2x4GB @1650MHz CL9 + Corsair RM650

    Doesn't look like a power supply problem at all.

    Motherboard, hard disk or something that uses a USB port sounds more plausible.

    Oh okay, damn... I hate having to troubleshoot motherboard issues! I'll have a look at the mobo and HDDs. Thanks for your advice everyone

    Also, dl HDD and check your HD. Those spinning disk HD's can cause trouble as they age, especially one as old a 7 years. A modern SSD of 500 - 1000 GB can supplant an old HD, make your system run much faster -- it's like getting a new machine.

    OTOH, you could have a RAM issue. There are testing programs for that. Finally, your mb could be dying. That would mean basically a new machine.
    CPU: Core i7 8700k, HT enabled, all 6 cores OC'd to 4.8GHz, Vcore = 1.24v
    Heatsink: Noctua NH-D15 with one NF-A15 1500 RPM PWM fan
    Motherboard: Gigabyte Z370X Aorus Gaming 7
    RAM: 4x16GB (64GB) Corsair Vengeance LPX DDR4 RAM 16-18-18-36@3200MHz, Vdimm = 1.35v
    GPU: MSI GeForce GTX 1080 DirectX 12 with 8GB 256-Bit GDDR5X
    SSD1: Samsung 840 EVO 500GB TLC; SSD2: SAMSUNG 860 EVO 1TB 3-bit MLC
    HD: WD 500GB (old); Case: LIAN LI PC-7H Aluminum ATX Mid Tower
    PSU: Seasonic Platinum 660W

    So, bad news... looks like it is either the mobo or CPU.
    Tonight the system did another random restart and afterwards could only boot to a black screen.
    I opened her up and saw a solid red light on CPU_LED. I tried unplugging everything except the CPU from the mobo (as well as taking the mobo out of the case) but it's still having the same issue.

    I'm guessing I'm out of options here other than trying to reseat the CPU?
    I don't have any spare CPUs I can swap in unfortunately. Maybe time for a new PC?
