Can using low power GPUs without a power connector harm PCIe slots during overclocking?
Can using low power GPUs without a power connector harm PCIe slots during overclocking?
I am likely older than you and hold an Electrical and Electronic Engineer degree. The power cap defines performance boundaries. Beyond 75 watts, the card’s speed becomes irrelevant; it will lower its clock speed regardless of how fast it could run. The sole advantage is achieving game performance within the power restriction. Once that’s met, you can push higher for better results.
The card will consistently struggle in every game, being constrained by its power limit and likely failing under full load. There won’t be much benefit until you bypass this restriction. Doing so could endanger the slot or motherboard if specs are exceeded.
My 2060 would reach its 200-watt threshold and then slow down from 2085MHz to 1995MHz or below. It stays close to the stock boost under full load at 175 watts, but adjusting the power limit won’t significantly improve performance. Unlocking the 2060’s power via a mod on the 6-pin connector gives a steady 2055MHz in games (not my setting, just what I got with a 2080).
With the 2080, the maximum power is 308 watts, which I rarely exceed. The peak boost stays stable around 2070MHz. Interestingly, both cards seem to draw similar wattages. I haven’t noticed the 2080 surpassing 200 watts for extended periods.
from what i recall, and my memory is accurate, around 750 ti models exceeded the limits on OC, causing some failures, especially without connectors. With a 1050 ti, there should be no issues since i don’t have any recent posts mentioning such problems.
I recall reading similar information as well, the 480 from AMD was said to achieve that too. With a suitable motherboard there might be a circuit to control the power usage. I haven’t explored bypassing the power cap for a PCIe slot before. Nvidia restricts the power you can extract from the slot, especially with my 2080 model. This suggests there might not be a way to limit the power drawn on the motherboard itself—perhaps just as a precaution? It seems there should be a method to remove the restriction by making some soldering changes on the card.
Regardless of what you do, the maximum output from the slot can't go beyond 85w anymore—it will cause throttling. The slots are likely rated for 94w plus or minus. That's the supply side. On the demand side, ATX standards specify that a PCIe add-in card should not exceed 10w, 25w, or 75w based on the card type.
I hold a foundation degree (HND level) in Electrical and Electronic Engineer from around two decades ago.
I completed city and guilds electronic servicing, a three-year program.
Additionally, I have CCNA and PC maintenance and repair experience.
But what's the point of all that?
Agree or disagree, it doesn't matter.
This is just a place for exchanging ideas.
As a moderator, you should respect the right of others to express differing opinions.
It's part of fostering healthy discussion.
So stay calm, relax, and don't let it affect you personally.
I've respected your stance and never targeted you personally.
I understand that perspective completely. That's precisely why I've chosen not to do it. The main point is that individuals aren't damaging their motherboards or graphics cards by pushing them beyond their limits on the 1000 series chips, since these devices actually have safeguards in place. Of course, someone with determination might try to bypass these protections, but you really need to consciously avoid those measures to prevent any harm. It's possible, maybe, but it's not likely for most people.
The main issue for the OP is that the card has only 75 watts which will be a hard limit on performance. If the OP increases the clock speed he will hit this limit and throttle. The card will only increase the clock speed much above stock if the power limit is not reached. I would guess that maximum fps would not change much. 300 points in firestrike at most and a few fps in games for pushing the card harder in games. As performance will be so low anyway, 2-4 fps will be like 7-8%. It really is not worth overclocking. The difference between 32.8 and 35.3 fps is not noticeable to the player in games like Deus Ex: Mankind Divided.

Bypassing the power limit is not worth the risk. Overclocking is mostly pointless.
