Enter 500W & Mercury 450W SMPS Review – Avoid Them
Here I am going to review two local branded PSUs that are quite popular because of their cheap price and wide availability. You can find these power supplies easily on online shopping sites or at any computer hardware store. So now we look at both these SMPS and find out whether you should buy them or not.
Enter 500W & Mercury 450W SMPS Review
Here is the review of Enter E-500A 500W and Mercury KEZ-M200 450W SMPS.
Build Quality
The build quality or construction of these power supplies is not good and they look very cheap. There is an 80 mm fan on the back which is noisy enough to irritate you. Both these PSUs are made in china. This is all I can say about the construction quality of these power supplies.
Current on 12V Rail
Now let us look at the most important thing in the SMPS which is the amount of current present on 12V Rail. For a decent SMPS it should be atleast 25A (ampere) for a PC without graphics card and should be atleast 32A for PC with a mid range graphics card.
Enter 500W SMPS
Enter E-500A 500W SMPS has 24A current on its 12V Rail which is very low especially for a 500 Watt SMPS. A good 500 Watt SMPS generally has 40A or more current on its 12V Rail. This Enter 500W SMPS has not enough power to run a modern day computer and even without an entry level graphics card installed.

Mercury 450W SMPS
Mercury KEZ-M200 450W SMPS has only 20A current on its 12V Rail which is insanely low and not at all recommended for any use. If you use this SMPS with your PC then you will risk your computer components of getting damaged.

Final Words
At last I would like to say that both these power supplies are very under-powered and not fit for any use, and if you use them then they can cause serious damage to your major computer components that includes hard disk, motherboard, graphics card, processor etc. So my advice is to avoid them at any cost and if you want good budget SMPS then there are other much better options available like VIP 400R and VIP 400R Plus SMPS which are priced in the same range.

hello Akshat, i am also a hardware & networking enthusiast from Mysore, Karnataka. Currently working as a system admin in a reputed CBSE school. We have lot of PC problems and found all cheap SMPS brands like CIRCLE, FRONTECH, ZEBRONICS, MERCURY. I want to recommend management about upgrading SMPS. but not too costly. what about VIP, IBALL, INTEX, Any other brand?
Hello Pradeep, Except VIP i would not recommend any of these brands that you have mentioned. If you need a good cheap SMPS then go for VIP 400R Plus. SMPS from higher brands like Corsair, Cooler Master etc. will you above 2k.
hello aksath, i want to know how good is iball marathon 500w ??? can you give me full information on itz 12v rail ??? and which psu is good under rs 2000?? i have pentium g2010, 6gb ddr3 ram, 2gb zotac gt610 synergy edition , gigabyte h61ms1 mobo, enter 500w smps, my previous 450 watt intex burned and i’m lucky that it didn’t harm any of my components..
It is not a good SMPS. In fact all iBall PSUs are very bad. They also do not have 12V current info on their official website. For 2k i would advise you to get Cooler Master CM350 Plus. You can get it here http://www.amazon.in/Cooler-Master-CM350-Plus-350W/dp/B005TPTQ24?tag=aksha0b-21
Hello Akshat Sir,
Since few months I am experiencing mild current when I touch my cabinet.
I opened it and when I touched my SMPS (intex techno 450watts) , I can feel current passing from it.
So do I have default in SMPS or motherboard ?
Thank you..!!
It may be a problem with earthing in your house. You can get it checked by an electrician.
Yes, it seems a problem with earthing. I checked my cpu in another room of same house and also in my other house. At both places I didn’t feel current.
Is it safe to use ? Are my PC components at risk ?
Should I consult electrician immediately or will it be ok if i call him next month ?
Also my CPU heatsink sometimes make lot of noise even if no programs are running.
2-3 times I have also noticed that it slows down, pauses and than again starts rotating and sometimes it rotates slowly and steadily.
Is it normal or there is some problem.

You should be fine with it and it is a common problem during rains in India. You can call the electrician next month.
Thank you..!!
But is it normal about my CPU heatsink noice and rotation problem ?
If you think the noise is unbearable then you can buy a good aftermarket cpu cooler. You can read about it here https://www.akshatblog.com/guide-on-finding-the-right-aftermarket-cpu-cooler/
dear dir ,
I wanted to ask whether cheap , local smps can have dual 12v rail . I went into a cyber café there there was a working computer which was just left open in that there was a mercury smps with dual 12v rail total amps was around 34 to 36 how can cheap smps have such good ampere . the owner of the shop is a big cheat he gave me a cheap smps, a fake motherboard , a fake ram and he also broke my old motherboard processor pins and told its broken
thank you
awaiting your reply,
This is because these labels printed on these cheap SMPS are also Fake. I never trust them.
Hi I have dell precision 390 cpu and need smps, hardware person bought oddyseey/mercury . I ask him to wait after reading your reviews. So do suggest which one will be good other than this.
Go for a better power supply such as Corsair VS450.
They dont have corsair , foxin 800 is fine?
I don’t recommend it personally.
