So lets take a quick look at the specifications along with its key features before we see what it really has to deliver off the paper.
Power DistributionBefore we look at the key features the point worth noticing is that the combined output of both the 12V rails is 396W which is substantial share of the total 450W power promised by the PSU. This shows that it is ideal for heavy and power consuming components like any of the AMD FX series processors or the Radeon GPUs as now the key components in any computer work on the 12V rail and not on the 3.3V or 5V.
Dual 12V rails: The Antec BP450PS 450W PSU comes with a dual 12V power rail configuration and this is a very good safety feature when it comes to protecting your components like processor and graphic cards from any voltage fluctuation or over load. Its a very welcome step at this price point as it will give the user an extra layer of protection especially in India where the voltage does fluctuate many times a day.
Latest Standards: If you look at the label closely you see that the power output on the 12V rails ie 396W, is greater than that of the 3.3V and 5V combined which is just 115W. It indicates that it is based on the latest standards and technology of the PSU world. So Antec is not selling you an old PSU in a new casing. This is a brand new product and not a re-branded component from their storehouse.
6+2 PCI-e Connector: It comes with one 6+2 PCI-e Connectors which makes it an ideal unit for using with any of the latest mid to high range graphics cards. You can easily run a mid range graphic card that uses a 6 pin PCI-e or a 8 pin PCI-e connector making it an ideal choice for gamers who want sheer power and no hassle from their computers.
4+4 ATX12V Connector: This feature not only makes it ideal to be used with power hungry processing beasts like the AMD FX 8350 Octa-core processors but also with high end processors/motherboards that require a combined 4+4 ATX12V CPU connector also known as a 8-pin EPS12V connector.
4xSATA Connectors: This is a common in a 450W PSU but its worth mentioning over here as it is available at a very competitive price tag unlike other which cost double than the BP450PS. With this you can easily connect upto four HDD/SSD or a permutation and combination between storage drives and optical devices. This is plenty and you'll not have to worry about converting any of the peripheral connectors for powering your devices making it ideal for a mini home server PC as-well.
The unit is surely designed to utilize all the 500W and not just a sham rendering the user unable to run most of the components in absence of the appropriate connectors.
- Has OCP protection
- Comes with one 6+2 PCI-e Connector
- New technology and not a re-branded unit
- Not 80% efficient
The Load TestI always like to put every thing that I get for review through a load test so that we can know how good or how bad the unit actually is. So not going by the brand name and trusting the Continues power 450W logo on the pack I put the provided unit through a load test at varied levels of loads.
I kept the PSU under 20%, 40%, 60%, 80% and 100% load to determine the actual output in real world tests and applications.
Each voltage rail's output was recorded under varied loads and the entire output was kept in the "Total" column.
The results, were quite impressive though
The Antec BP450PS passed with flying colors! Not only did all the rails delivered the promised outputs at varied loads but the total value was beyond my personal expectations from an ultra budget power supply unit. For example, at near 100% load the total wattage delivered was fascinatingly 448.9W which is minutely less than the promised 450W and obviously nothing is fully efficient so this is a great score.
Also during our test we witnessed a 74%-75% efficiency along with the PSU staying under 40 degree Celsius with the room temperature at around 36 degree Celsius showing that the 120mm quite fan does it work pretty well and yes it did not sound like a jet engine running, it was indeed cool and quite as promised by Antec.
My VerdictThe Antec BP450PS is roughly priced at Rs 2400 in India and is aimed at the ultra budget to budget users. With a continuous 450W output working with near 75% efficiency along with latest architecture and a dual 12V rail it is an ideal PSU for those looking at a decent and reliable power supply unit for their home. office or medium range gaming built. You can pair a powerful processor like the AMD FX 6300 and R7 250 1GB DDR5 GPU or an Intel i3 with a GTX 750ti and in some cases play wild and stretch the PSU to its limit with a GTX 960 if you are not using too many fans and HDD in your built.
I strongly recommend that Antec BP450PS to anyone who wants quality and has around Rs 2500 to shell in his pocket.
