Sentey has been dedicated to providing quality computer components since the company’s inception in 2001. Primarily focusing on IT hardware solutions, Sentey has nevertheless developed an excellent line of components that fit the consumer market as well. While not explicitly a gaming computer, the feature-rich nature of their MBP1000 power supply has everything that you will need to power an exceptional gaming machine.

Aesthetically, this power supply is comprised of black metal and utilizes a metal-bladed fan for high performance cooling. This power supply is also semi-modular; this means that you’ll have some choice in how many cables you have running in your PC as you won’t have to have all of the included cabling inside the computer if you don’t need it. Some cables are permanently attached to the power supply though, which is why it’s a “semi” unit. The permanently attached, mesh coated cables include a motherboard 20+4 pin connector to power motherboards of this type and a CPU 12V 4+4 pin connector to power the other type of motherboard interface. The difference between the two is electrical connection type and they can vary dependent on your setup.

The modular connections included with this power supply are one CPU 12V 8 Pin to power your processor, six PCI-E 6+2 pins that can be used to power your graphic cards, and an amazing eight SATA cables for the powering of your hard and optical drives. For legacy peripherals, this PSU also includes four Molex connectors for IDE connecting hard and optical drives as well as a floppy connector for those who still utilize this connection.

Our Gold Pick also has the distinction of being the power supply that also has the highest wattage of any of the units on our list. At a crisp 1000 watts, you can expect that you’ll be able to place a fairly high power draw on this system without much trouble; as a matter of fact, this is a great power supply to utilize on a gaming system that utilizes a scalable link interface (SLI) or the proprietary ATI Crossfire system. Systems that run these types of interfaces have the capability of running multiple graphics processing units (GPUs or graphics cards) in one system. Typically, any system that runs this setup will draw a lot of power; the higher end the card the more draw, and this power supply is certainly up to the challenge.

No one wants a computer that puts a sizable dent in the monthly electric bill. Even for a gaming machine, power supplies can still ensure that your computer is running as efficiently as possible and thusly not draining your monthly power allotment. Conceptualized in 2004, the 80 Plus Standard of power draw efficiency is the primary rating system that the majority of power supply manufacturers utilize to ensure that their devices are as energy efficient as possible. We’ll get into more of the details of the rating system in the pre-purchase considerations but for now you just need to know that the higher the status above 80 Plus, the better the efficiency. This PSU does fairly well in this rating system and has scored a 80 Plus: Bronze status.

Internally, this device runs a single strong +12v Rail system that utilizes a 100-240V auto-switching system to manage the voltage. Rail technology simply means that with one rail, all peripherals are receiving power from one connector. Multi rails balance the amount of power for different peripherals by utilizing several rails.

As our Gold Pick, this device has to fair really well with consumers and critics, and this power supply certainly performs well in both regards. Currently on Amazon, 89 percent of 520 reviews are very positive for this power supply; at least a four star rating level. One positive, five star review states, “I purchased this power supply to replace a defective Corsair Professional series Gold certified high performance power supply (CMPSU-850AX). The Sentey is working flawlessly and is holding up to all of our household gaming needs. It not only provides ample power for the MB (ASUS Sabertooth X79 /w 32gigs ram – 2SSD’s – 1tb WD Blk), but it also has the extra leads for those of you with two gaming video cards in your system.”

Their Toughpower 850 Watt Gold is one such power supply that would be perfect for your gaming rig.

Firstly, while this unit is described as full modular, it is in actuality a semi modular styled power supply. This isn’t much of an issue as the permanently attached cabling powers items that are required to be connected in order for you to compute at all.

Pre-purchase considerations


Gaming machines can employ a monstrous amount of cabling. Some gamers have multiple SATA drives for their files, a solid state drive (SSD) for their operating system and a few key programs, multiple Blu-Ray drives for their movies and software, and power hungry graphics cards and gaming motherboards that need extra PCI-E cabling for high performance. All of these things will need power from your PSU, so be 100 percent sure that your prospective power supply has enough connectors so that you don’t have to perform peripheral triage in order to get your system up and running. Also, keep an eye on the connector type on the PSU, it wouldn’t do to have too much of a nominally used type of connection and not enough of one that you need much more urgently.

Over Temperature Protection (OTP)

Power supplies can generate a lot of energy and as a result they can get blazingly hot; especially if you are overclocking your system. Gaming PSUs with this protection will shut down and start the cooling off process if temperatures approach a pre-set high value. This is definitely a feature that you should consider if you are planning on overclocking a system that is going to be running a SLI’d set of high powered graphics cards. You certainly don’t want to fry your system.

Energy Efficiency

The majority of power supplies on the market today use the 80 Plus efficiency ratings system. This rating system is entirely voluntary yet is very valued by the majority of power supply manufacturers. These ratings certify whether or not a specific power supply can operate at 80 percent efficiency at 20 percent, 50 percent, and 100 percent of a pre-set power load. These ratings range from a sufficiently efficient 80 Plus rating, to an incredibly efficient 80 Plus Titanium. As a rule, higher rated power supplies tend to go for more cash. Also, when you employ energy levels that are slightly higher, this tends to decrease efficiency, though not always.

Modular vs. Non-Modular

Cables can be the bane of a gamer’s existence. Many power supplies come with the cables that connect your SATA, SSD, optical drives, motherboard, and graphics cards directly to the supply. These cables are permanently attached and there isn’t much to do about cables that you aren’t using. These types are called non-modular power supplies; and as a rule, they do the job, but the inside of your case can be a cabled mess. Modular power supplies eliminate the excessive cable content by allowing you to remove you don’t need or attach any cabling that you do. This ensures that if you only have one SATA drive, you don’t have to have three more empty SATA connectors inside your PC. Some of these types of supplies even come with a handy bag to put your additional cables in when you don’t need them. There are also semi-modular power supplies that do have some permanent cables, but only for the components that absolutely have to be powered for your computer to work.

Additional “Bells and Whistles”

This might seem silly to some, but nothing is cooler for a PC gamer than a machine that screams “GAMER” when you look at it. Many gamers purchase system fans that have LED light functionality, cases that have increased illumination, and even keyboards and mice that can almost light up an entire room, so why not have a power supply that glows an eerie blue? Many gamer targeting power supply companies are offering models of power supply that glow various colors when plugged in. These utilize LED technology and it can really make your computer look cool and gaming worthy. When you are looking for a new power supply, don’t ignore some aesthetic “bells and whistles” for your power supply; you know it’s providing great power for your system, why not have it be recognizable too?

Conclusion (Wrapping it up)

It’s definitely a great time to be a PC gamer. With the advent of new graphics technologies, better multi-platform games that don’t simply exist only on consoles, and PC friendly communities like STEAM, the realm of PC-based gaming is bound to gain even more popularity in the coming years. Make sure that you are prepared by having a great power supply that can handle the load of today’s games. We’ve provided this guide so that you can get an idea about some of the better power supplies that are available to power a dedicated gaming rig as well as some pre-purchase considerations. Just remember: when constructing your killer gaming rig, make sure that you have all of the peripherals to provide you with hours of gaming enjoyment.
