5.0 out of 5 starsThe EVGA 450 BT had no problems at all handling the power needs of my system under heavy load and stayed cool to the touch
Reviewed in the United States on October 7, 2017
I recently purchased this PSU to replace the one in a cyberpowerpc that I recently purchased as well. The reason I replaced the power supply, even though it was brand new (used for 1 day), is because of the multiple reports of very low quality PSU's used in some of their builds, and I couldn't find one single specification online for the one that came in the pc I purchased. EVGA has multiple 450 watt PSU's available but this one was $10 less than the next lowest priced 80+bronze PSU from EVGA. As far as I can tell, the only difference between this one and the others they have available is that this one is rated to produce a continuous 450 watts at 30 degrees Celsius (86 degrees Fahrenheit) while the others are rated at 40 degrees Celsius. The actual spec on this PSU is +30 but since it doesn't state how much above 30 degrees I'll just assume 30 even. I have this power supply running in a system with a core i5 7400 CPU, an AMD RX 580 4GB graphics card, 8GB of 2400mhz RAM, a 1TB 7200 rpm HDD, 4 case fans, a cpu fan, and 2 fans on the cooler for the graphics card. I stressed this setup with a few different benchmarks including Cinebench and Unigine's 3 benchmarks; Heaven, Valley and Superpostition, all on ultra settings. The GPU was running at %100 for almost the entire time the benchmarks were running and the fans (7 in all, not including the one built into the PSU) were also all running at %100. The EVGA 450 BT had no problems at all handling the power needs of my system under heavy load and stayed cool to the touch. It also features built in over voltage, over power, over current, under voltage, and short circuit protections. This means that if something were to happen to the PSU it should keep the rest of my system from harm, which gives me little more peace of mind. It also uses all black cables, a feature not often found on PSU's that cost $10 or even $20 more than this one. And while not modular, cable management was still pretty easy and, in my opinion anyway, looks pretty good in my case since it has a cover for the excess wires. The sleeve bearing used for the 120mm fan also keeps this unit running pretty quiet, which is nice. So unless your system's needs exceed the output of this power supply or you plan on using it outside in the middle of summer, I wouldn't have any worries making this purchase, especially since it comes with a 3 year warranty. And if you don't know how many watts you need in a power supply you can google "power supply calculator" and use one of the many free tools provided to give you a recommendation on the specs you need. I included some pics so you can see what the wiring looks like after installation. I'll also include a list of cable specs in case there is any confusion.
One 20+4 pin connector for the motherboard on its own cable.
One 8 pin (4+4 pin) connector for the CPU on its own cable.
Two 8 pin (6+2 pin) connectors for the GPU share the same cable with about 5 inches between the two connectors.
Four SATA connectors in total: Two SATA cables with two connectors each.
Three Molex connectors on one cable + 1 floppy cable
5 stars for value, warranty and peace of mind. EDIT: this PSU cost $30 with a $15 rebate at the time of my purchase.
