    Default PSU Advice needed

    Hi guys. My current rig is:

    MOBO: MSI H81M-E33 LGA 1150 ATX Intel Motherboard (had to get a cheaper one like an year ago)
    CPU: i5-4670K Haswell (will be OC'ing to 4ghz)
    GPU: Radeon R9 Fury (Sapphire Tri-X)
    RAM: 8GB Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) + 8GB G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 1600 (PC3 12800)
    CASE: Rise ATX Full Tower Game Case - Rosewill
    STORAGE: 1 SSD (512GB) and 1HDD (1TB)

    I need to replace my Corsair CX600M (bought in 2013) since it cannot handle R9 Fury I bought a week ago. Any recommendations? I was looking at:

    EVGA Supernova B2 750W
    SeaSonic S12II Series 620W

    Any other recommendations welcome, I'm on a tight budget thus those two choices.

    Side questions if you could answer:

    1. Will my CPU be a bottleneck for R9 Fury?

    2. Is my motherboard bad for the parts I have?

    Thank you in advance.


    EDIT: It was the power supply. It's working flawlessly after I changed my PSU. Thanks to all those helped

    It should handle it.... Just fine... But if it actually doesnt handle it...


    Why not go for:

    The Rosewill photon is 69.99 @ newegg. Why not go for this.

    1. No it won't be a bottleneck (shouldn't be...)
    2. Yes. it kinda is. It won't be able to overclock your cpu.

    Why do you think so?

    While you didn't bought a really good power supply, it should be enough for your PC with Fury. If it isn't it means the PSU is faulty and should be replaced asap. In that case a high-end 450W PSU is enough for CPU overclock only. If you want to overclock both the graphics card and CPU to the max you should be looking for a quality 550W PSU. The EVGA Supernova B2 750W and SeaSonic S12II Series 620W aren't really good choices.

    Your motherboard isn't bad for the other parts, but isn't meant for overclocking if it's even possible. Not that it matters much, the CPU already has a standard boost frequency of 3,8GHz, so overclocking to 4GHz isn't gonna make any difference in real life. Your CPU is also fast enough for a Fury.

    Thank you for the input. I guess I won't be overclocking after all, I just thought my haswell would be a bottleneck for the GPU.

    The reason why I'm suspecting the PSU is because my desktop restarts once it's on heavy load (Witcher 3, just moving around would cause it to restart). Which PSU would you recommend?

    That could be a faulty PSU. But isn't a PSU that gets overloaded.

    Sandy Bridge, Ivy Bridge, Haswell, Broadwell, Skylake, Kaby Lake and Coffee Lake are all just minor upgrades IPC wise, especially the last generations. The big difference is that Coffee Lake is gonna have a hexacore CPU in 2018. Which is the first for a mainstream platform from Intel.

    Which PSU would you recommend?
    At this moment the Corsair RM550x is a good choice on Newegg with rebate for only 69,99. It's a really great high-end PSU that has 10 years warranty.

    I hope there isn't something wrong with your motherboard or graphics card.

    Are you using one PCIe per cable or two PCIe connectors on one cable?

    I hope so too. I'm using two PCIe connectors on one cable.

    Edit: This PSU worked fine when running 560 GTX Ti, this started to happen after I installed the GPU. GPU is handling other games fine like SC2 or Hearthstone, it only happens when I play games like Witcher 3.
