(CX450M) Cheap, modular power supply. Got it off a flash deal on Newegg

Great power supply for the money. It also is great because it is semi-modular. That means there are fewer cables lying around in this pc. That can make a noticeable difference in a pc where everything is passively cooled and requires case air flow to keep everything cool.

Semi-Modular. 80+ Bronze. Got it at a good price.

Nice Corsair product for a low-power system. In a smaller case the semi-modular design can be somewhat annoying. But features like a five year warranty and black threaded cables make up for that. Good PSU.

Semi-Modular design helped with cable management a lot. I wasn't going to use too much power with my build so 450W was fine. Love the fact it doesn't run the fun unless it really has to which reduces noise.

Jonnyguru has a great review on this unit if you are interested, I will link to it below.

It has a long 24 pin and 8 pin EPS cable which is very nice. For its normal price of ~$50 it has a unbeatable bang for your buck. If you are on a budget for a PSU and only have around ~$50 I would strongly suggest this unit because unless there is some crazy flash sale you aren't going to get anything better.

Good power supply. Not a gaming or overclocking psu, but more than sufficient when used within its design.

from completed build I have finally built it.

Good PSU, runs cool and provides power to everything in the computer. No problems so far.

This is my only regret from the build. Temps are working fine with an ATX PSU, and airflow is fine after some cable "management" but I am getting a weird thumping sound from the PSU that is audible at idle. I wish the fan turned off at idle; it is the only thing preventing this from being a silent build.

I would recommend spending the extra $30-50 and getting the Corsair SF450 SFX PSU. The ATX cables are WAY too long. Since I already invested, maybe I'll splurge on custom short cables to eliminate the PCIE/SATA bulk (but I'll forever have a huge motherboard cable bulk). Going only an M.2 drive would help a lot too.

Also this PSU does NOT include a SATA power cable that can easily power an SSD mounted to the bottom spot on the case floor. See the pictures, but none of the power connectors are straight, and the 90 degree bent cable goes the wrong way, bending into the case. I had to only mount two screws in the SSD, and now the power cable is bent in, and the SSD is half hanging in the air. Not ideal and stressful on the cable.

I originally mounted the PSU up, then I switched to down just to try to minimize noise from the bumpy fan.
