I tried a redandant ATX power supply "FSP Twins Pro 700W"

FSP's "Twins Pro 700W" is a power supply unit that has a built -in two modules while maintaining a general ATX power supply and a redundant configuration.The actual selling price is 59,900 yen.

Earlier, we introduced the power supply "Dagger Pro" that achieved a maximum capacity of 850W in SFX size, but it is not an exaggeration to say that TWINS PRO is also using the company's miniatric technology.Two modules that can output 720w are pushed into the size of 150 x 190 x 86mm (width x depth x height).

Of course, when it comes to depth of 190mm, it belongs to a long one in ATX power supply.The mainstream is 140mm, and at most about 180mm.Nevertheless, modern ATX cases are abolished the front bay, so they can be incorporated unless they are very compact.

Generally, lidandant power is used in servers and special workstations, not unusual for a dedicated power supply.The TWINS PRO 700W topic is that it can be used in ATX cases, which are highly affinity with your own work, you can use the lidandant power supply with your favorite system, and realize the same hot swap as the general redundant power supply.

Of course, the power supply capacity of 700W is a bit unacceptable when combined with a processor like Core i9-11900K, which is over 200W peak or a high-end GPU of the TDP 300W class with a GeForce RTX 3070 TI or higher, but if it is a mainstream configuration.You can do it.

By the way, the Twins Pro 700W sent as a sample this time, but I was surprised because it arrived in a much larger package than expected.That's because the module was not built in advance, but in an individual package.It may be a message that the failed module can be replaced by itself.

The size of the module is 59 x 58 x 154mm (excluding handles and fans, etc.) by actual measurement.The front has a terminal and a 27mm thick 40mm square fan.There is no fan guard, but there is no problem if it is incorporated into the chassis.The back has a handle, and it stays on the chassis with a claw.When inserting, slide along the rail as it is, and when removing it, press the claw with the thumb and pull the handle with the remaining finger.Maintenance is excellent.The output is 720W.

On the other hand, the cable is directly coming out of the chassis, and it is not a popular modular type in recent years, but this will not be a way to reduce depth.The connector to be prepared is 24 pins for the main ATX, 12V assistance 4+4 pins x 2, PCI Express 6+2 pins x 4, 4 -pin x 2 for periferal, SATA x 6, 4 -pin x 1 for FDD.。

In addition, USB 2 of the motherboard.A cable to connect to the 0 pin header is prepared (it can be connected to USB Type-A by conversion).If this is connected, the dedicated utility "FSP GUARDIAN" allows the voltage status, fan rotation speed, temperature, and output watts, etc. can be confirmed.

Actually Core i5-10600+Z490GTN Motherboard, G.I tried to test in a simple environment with Skill's Trident Z Royal Elite.Regarding the operation sound, it reaches 4,500 rpm even when idle, probably because a small fan is also adopted, and it sounds slightly higher than the general power supply.In particular, immediately after the power is turned on, it turns full rotation, and a "server -like sound" sounds.However, if you put it a little away in the case, at least the impression is that it is very noisy when idle.

Of course, the cable will naturally be connected, but if you connect one side, the LED on the back of the module will start to shine.The LED turns red, such as the state where the other is missing, so it is easy to understand visually.

As mentioned earlier, if you connect the USB, you can monitor the situation in real time from the utility FSP Guardian.In addition to the fan rotation speed, the item can be confirmed in addition to the temperature, output, and voltage/current amount for each module.The graph display is not possible, and it only monitors the current situation, so it is the minimum necessary function.

From here, when one of the power cables of one module was pulled out, a lively beep sound was heard from the power supply body, and it was confirmed that the module condition would change from green to red even in FSP Guardian.In addition, since this unit comes with Thailand to make it difficult to get out of the cable from the power supply, it will actually be heard in the event of a disconnection or a plug from the outlet side, or in the event of a failure of the module itself.

As long as the FSP Guardian is monitored, it seems that both two modules are output at the same time.However, just because one can output 720W, it does not mean that a total of 1,440W can be output.I want you to think that there are two for the redundant configuration.

Since this product is exposed by the module side, the maintenance when dust accumulates can be performed with the server on the server (although the beep sound must be endured a little).I don't think it is suitable for personal or gaming applications, but if you are making your own file servers and business servers in SOHO and SMEs, if you want to reduce the risk of power problems even a little, it is a good option.Isn't it?
