Wires Cables and Cords
Wires Cables and Cords. Not sure why there is no pictures of them but here they are all in their glory. I forgot to measure the length but for me they were plenty long enough. I have an archaic system with 2 SATA drives and a DVD burner so there were a lot of cables left over that zip tied and tucked away in a cubby hole above the drives. I was getting BSOD with so many different errors I knew it was hardware and decided to start with the power situation first. So far so good. This thing is either real quiet or my other one was loud but I can not hear anything at all down there. I think I am going to order another one to park on a shelf just because. Now to look into surge protectors since mine obviously is not doing it's job anymore.

5.0 out of 5 stars Honest Review after 6 months of using
Reviewed in India on February 6, 2021
Reviewing after using it for almost 6 months. So this will be a long term use review with my honest opinions and suggestions. May be this will be a bit lengthy but I will try to vover every aspect of it...

1.Packaging- So the first initial impressions of a product comes from packaging but amazon did a very bad job for it. They delivered the item in the original manufacturer box with some stickers on it. That means no extra protection was included. So, bad to see such things from such big brands like amazon. And for that the box was little damaged while shipping. But thanks to Gigabyte who provided really good foam packaging material inside the box to protect the Power Supply. After all packaging was teribble.
I found everything to be safe and brand new. No problems regarding that. We get the power supply with attached cables(no modular system in this price point), instruction manual and Power cord.

2.Performance-Now lets talk about the main item the power supply. But before that lets talk about my system, I know you guys will think me crazy or stupid after listening what I actually paired with just 450w power supply. My PC configuration is Ryzen 5 3600 + Aorus Elite B450 + Gigabyte Gtx 1660 super 2x edition. So at first I know it requires atleast 550w power supply but trust me guys in this 6 months I never found a single problem with this 450w. As it is more capable of delivering high powers when required. That's why you should go with a good brand power suppply with good ratings.

Now again coming to main products its really good with 120mm silent cooling fan. The fan never Ramps up in normal condition but when in load it ramps up but still not loud I must say. I like the build quality. There are many connector in this power supply. Starting with 24PIN ATX, 1*8pin CPU,2*8Pin PCIE for gpu,7 sata, 6 molex with 1 floppy connector. So overall it is nice. It is not a modular power supply but thats fine in this price point. Their is another version available of it with high watt rating of 550w, model is p550b. See guys this is great power supply with 80 plus bronze rating. Oh I forgot about the cable quality. Here is why it is better than Corsair Vs450, it comes with black flat cables. Every cables are black flat type so it gives a premium loook of PC. So after alll great for price that it comes, I got it for about Rs.3000. A great deal.

3. Conclusion- Just go for it, no problem regarding any thing just keep in mind its is a non-modular power supply so you have to do cable management for extra cables. Otherwise no power supply in this proce point have such a great quality with such pros. It is better than Corsair vs450.

Pros-
1. Good Quality Material is used.
2. Best Cable type(flat and black) in this price range.
3. Many connectors available.(Rather than dual 8 pin cpu, only 1 8 pin cpu is their) .
4. Good power delivery.
5. Silent fan.
6. Long wires

Cons-
1. Lots of wires fir cable management.
2. Bad pacakaging.

Thats it for now. If you like it thrn thanks. Hope it helps you.
