  • Rated 5 out of 5 stars

    Love it!

    Had to buy this as a second option after first Thermaltake PSU was DOA. Love that it is semi modular. Not a lot of wires taking up unnecessary space in case. Worked without any issues. Very happy with it so far.

    Corsair 650W PSU

    Works well. I had no problems using it and it comes with a good selection of cables. My only two problems was that the 24pin isn't removable from the PSU end, and the GPU cable is ugly and has the extra PCIE 8pin hanging out. Seems quiet but overall looks good.

    Excellent power supply that’s also affordable.

    Good power supply that packaged nicely. I bought this for supply, mainly because of the price, but I had to return it because it didn’t have enough PC cables for my graphics card. There were supposed to be two cables, for mine only came with one, so I returned it to Daisy chain cables from the power supply to your GPU, it does not provide enough power. I would’ve kept it if it came with enough cables.
