    Caught this on sale. Was easy to hide the main 24 pin wire and 8 pin motherboard that are non-modular. Others were easy to fold up and tie back (the modular pieces). Look extremely nice in case. Runs Quiet, I can hear again.

    Very reliable and stable PSU. Love that its semi modular so it cut down on the clutter in the case. Should last for years to come. 650 watts is great because it allows you room to upgrade as you go. Love it.

    This PSU has been great at powering my i7 11700f alongside an AMD 6650 xt GPU. It is very low noise as I hear the GPU fans more than I do this fan. Being semi-modular is not a problem since I am not using any sata components and only needed one 8 pin connector for the GPU. This is a great PSU for a budget build.

    So far so good, been in my son's PC for 2 months now, without issues. Install was easier than removing the old one. I like the semi modular setup, you don't have a clustered mess to deal with and try to find a place for useless cables.

    You can’t go wrong with this PSU. Reliable and at a great price. I’m using it with a Ryzen 5600X and a RX 6700 XT and works like a charm. Quiet and semi modular. Planning on upgrading some components next year but the PSU will be used in a different computer for sure

    Cable management is going to be more difficult if you care about that sort of thing but the PSU is running stable and I don't notice any noise. I am a new builder and appreciate the lack of guesswork to determine which cables to use for the 24 pin and CPU power connectors but most would probably consider this more of a con. Overall it seems to be a great power supply for the price so far.

    Good power supply at 80% efficiency. This is the second one I have purchased (2 PCs) Note: this is not 100% Modular (Main MoBo connector and CPU connector are hardwired into the PSU) All cables are long enough for a full size Case and ATX motherboard. This will power a i9 10850 with 64gbs ram, 2070 Super ultra and 2 SSD M2 1gb drives plus a AIO corsair 240mm with 4 fans + 4 case fans.

    The lower supply was PERFECT for my needs, and I was able to feel assured it wou6be by the person I spoke to about all my questions. What can I say, other than this is THE SECOND superlative review I am able to write about this store and my purchases there. The employees who help me every time are courteous and kind. Don't make me feel rushed, or anything. Yet they have my items ready when I arrive and I'm out the door in like 3 minutes. Stellar employees.

    One out of two was DOA

    Bought the last two of these while I was "in town" (which is a trek) for adding a GPU to my son's rig and for an upgrade to mine. Liked the look (though I don't have transparent cases so NBD) and fully modular aspects, and the rated capacity. Thought Corsair was good quality. One worked OK, the other wouldn't boot either board. Fans spun but little else. This was a system which was running on a 300W PSU before, so definitely not overloaded. Sigh. Infant mortality is a real thing in electronics, and perhaps that's just all this is. Would have liked for it to have been more thoroughly tested than bad out of the box. Small sample size but at least Best Buy refunded no worries. Bought a Thermaltake to replace, that's working fine so far. The one that works is good so far, quiet.
