With about 10 – 15 million VND gaming computers, most of the money will be focused on important components such as CPU, VGA and RAM. Then there are things that are Mainboard, SSD … That’s why the case cover and power adapter are often ‘spurned’.
However, with the importance of the power supply system for the whole system, you need to be very clever! Choosing a medium that still satisfies the system’s power needs, both in capacity and stability, is relatively difficult in the budget range. And the appearance of Forgamer RA400 / RA500 is really remarkable!
Forgamer RA400 / RA500 has the same box as well as the same appearance design, only difference in capacity. RA400 simply has a capacity of 400W and RA500 is 500W.

The wires of Forgamer RA400 / RA500 are wrapped though two main stems are 24 pin and 8 pin, 4 pin wires for hard drive or 6 pin for VGA are all exposed. The length of the rope is good, not missing, not enough, installing a full tower case is enough.
Going into this source, we will together ‘dissect the stomach’ to see what is inside. First of all will be the RA400:
The design of the RA400 is relatively classic with 2 stages of filtering, but first and foremost it is noticeable that the cooling fan made by Forgamer itself: The 12mm size is red and the speed is 1800 rpm to cool the components. in.
IC protection has 3 basic levels OVP, UVP, SCP.
Firstly, the Forgamer RA400’s input source looks very simple, lacks noise suppression and is quite important is the power switch. You will need to unplug the power cord if you want to unplug the PC.
The key parts in Forgamer RA400’s “rectifier” are the GBU406 diode, ChengX’s 150uF 450V main capacitor, which is quite strange.
The transformer used in this source is the ERL30, the basic circuit design uses a pulse diode combination to rectify the current for each power line: 1 pair of 20A capacity. Finally, the output filter capacitors use 2 brands ChengX and Asia’X.
Next will be the similarly designed Forgamer RA500.
WAM fan is also 12mm, speed 1800 revolutions per minute for cooling.
The input also lacks a filter capacitor, such as a power switch.
The main filter capacitor is bigger than the 400W version from ChengX, 220nF and 450V.
The ERL35 transformer is also a bit bigger, the pulse diode combination to rectify the current includes 2 25V units.
In terms of performance, according to the testing of the reputable review page f14lab, Forgamer RA400 / RA500 both achieve around 80% efficiency. In which the 400W version achieved a slightly more standard output current than the 500W version and they both ‘slipped’ on the power retention time test.
Overall, the Forgamer RA400 / RA500 power pair works well in mid-priced, cheap gaming systems of about VND 15 million with good performance. Currently the 400W version costs about 700 thousand VND and the 500W version is 900 thousand VND in Vietnam.
