What is the benefit the graphic cards which have back plate ?
What will be happen if the back plate doesnt exist on a graphic card ?
What is the Nitro for ?

Backplate is for containing an event of card failure, i.e. keeping pieces of the card contained and the electrical fire hazard.

Backplate also helps to reduce the heat of the GPU.

I took mine off the cards ran cooler so no idea really how to answer why some say it run better with it, mine run better with out it .

I think it's just marketing.. coolness factor.

looking at my msi r9 390, the metal that serves as ram heat sink is screwed to the back plate to better dissipate heat from the rams, maybe some cards have it for looks, and some have it for heat dissipation. |

99% it is just for looks, and gives some added protection.
1% is for reducing heat but I watched a video and it had little to no effect in reducing vram temps
I really like back plates though, they look awesome and reduces some fear when handing the card.

Yeah I LoL'ed at that explanation too. Not sure why lol.. If you have ever seen a capacitor on an older gen card break from lv or hv then you would know. Breaks right through the back of the pcb, burns completely through it, and shits electrical fire out of the back consistently. Does that make sense? Do you want that shit all over your motherboard, inside express slots? its 100% for this reason exactly |

well, what if you blow air at the back plate? the vram heat sinks are connected to the back plate thru metal screws, i'm guessing in the video the air is still at the back plate. for us miners with multiple gpus, i believe back plates protects from shorting accidents that might happen in tinkering around rigs. specially for those who are lazy to turn off their rigs while troubleshooting. |

They help a little with heat dissipation on systems with only one GPU in the system, or where the GPUs are WIDELY spaced apart.
They're a MINUS in a system that's crowded as they reduce airflow.
They offer some physical protection to the card and make it less likely you will damage the card via ESD while you are handling the card.
Caps shorting out can be VERY dangerous.
Had one go the length of a LONG room (40 feet or a bit more) and imbed the wire in a concrete block wall once when I was a power supply test tech - pure LUCK it didn't hit anyone on the way, it could easily have put someone in a hospital if it had hit them in the wrong place.
That cap was somewhat larger than anything on a current GPU card (600v 10uf or some such as I recall, 2 inches long almost + axial leads and almost half inch diameter) but the principle is the same....

i have this two rx 480 with backplate connected directly at the motherboard, the one above the other is hotter of course, pointing a 90mm fan at the backplate reduced the temp by 2c of the one above...and i didn't watch the temp any longer, so i don't know the end result and didn't do longer observation.

When i m mining, the back plate is so hot. I think there is advantage for cooling. if we think that the graphic card works 7/24, the back plate is usefull. it feels trustable that it is a good product. Maybe because of the appereance. But is it valuable to pay extra money for it ? |

To prevent PCB bend is the #1 reason for them

looking at my msi r9 390, the metal that serves as ram heat sink is screwed to the back plate to better dissipate heat from the rams, maybe some cards have it for looks, and some have it for heat dissipation. I have three RX 470 one of the RX 470 has one the other doesn't, the one with a case type back plate gets hotter then the one with out one i even checked the Vram on both with wattool no back plate one is cooler and the third RX 470 with no back plate runs all most as hot as the one with one . why i said I don't know or gonna try to explain why . by no back plate one has one but it has holes were it can short out and even be dmg by ESD it's runs the coolest of the three . the third one i can touch everything on back has no protection at all but is also is the lightest of the three it is very lite and the one in the case type back plate runs the hottest has no open holes on the back and is heavy. My R9 280 ran hotter with it before i watered cooled it i took it off , could have left it on but it seems to run cooler with no back plate . watered cooled with a small fan from the kit blowing on the vram. Vram is even cooler . |
