they plug right into the motherboard? ..they probably don't use a lot of energy but do they use enough to impact my pc performance?

no they lug into the card that fits the expantion slot and it uses at most about 10w led don't use much power but to be safe always have an extra 50 - 20 w of power extra for power jumps. 50 recommended 30 is the least i would feel safe with.

They do not plug into the motherboard actually. The back bracket, seen in the middle of the loop of lights in the product picture, takes up an expansion card slot in your case (and blocks one pci / pcie slot on your motherboard.Power comes from the old school 4 pin power connectors used for fans / older CD ROMS and hard drives.

You won't even notice. The only power this thing needs is from a molex plug off the power supply.

It dose not plug into the motherboard it connects with a 4 pin that comes from your PSU. No it dose not affect performance.

they plug into a standard molex 4 pin (ide HD Style) power port. They also com with a switch you mount in an open slot in your case (the back of the case where the i/o slots are.

You don't need them at all for normal use; overclocking/overvolting would benefit from the heatsinks to maintain the longevity of the chips. Small overclocks (up to 1 GHz) generally won't require them in a normal ambient room temperature.

All mother board power connects are near the same u will be fine as long as it isn't a server mother board. Which it isnt

It doesn't put a load on the device. If you want a load, you can leave the rest of the devices connected so that you're only missing the mobo, but of course, that would be like testing water with your big toe; nowadays the mobo and graphics cards are the main power draw on the system. Therefore, the only true test is to plug in a known good psu and check out the system performance. I'm assuming you bought this device to test more than just your own psu, so you're probably a computer tech and you'd have other psu's available. This is what you'd do if your graphics card was suspect -- replace it with a known good card.

Funny thing is.. They connect to the motherboard.. You will see were they connect and say fan1 to fan2.. Awkward set hp of how it works..

My experience: I have a fan-less PSU and the stock setup is adequate. However, I do not use their included fan splitter, because my motherboard supported multi-zone tuning (no evidence that this is better/worse... YMMV). Fans are off/low most of the time under normal load. Hope this helps...

They're not noisy for me. Is it the lights themselves, or the power supply you're using?

I run my i7 and 780ti just fine. 60w idle and about 360w load? I haven't measured in awhile

Do you have any internal fans? If so are they blowing out.....not sucking in.

I run a thermal take 650 watt psu and I have no issues with power consumption

I think they do,I am using them in my computer now and they are working fine,sorry I can`t give you a better answer.

Yes I have two of them running on a 650 watt PSU along with a liquid cpu cooler so either my PSU is about to blow or these use less power than they need...hope I was helpful!!

I have minimal wattage from my power source. the rating is for max need. mine runs my media center without lag i don't know about games but i am very happy with my graphics. i think you have more than enough wattage. and you can't beat the price

where you plug them in is irrelevant, but connecting them to the motherboard is usually preferred. if they're too loud, I suspect vibration against the case. Did you use the included rubber mounting plugs to mount them?

This would consume 1.8v instead of 1.6v. Technically it depends upon motherboard/ pc spec what ram they allow/limit. Going down from 1.8v to 1.6v was easier to assume. If there is no limitation from motherboard then then ram should work with slightly more power consumption.

The watt usage is what you should be concerned with, i assume your psu has a 12v rail. Realistically unless you have an extremly small non-gaming setup and psu there should be no issue running as many of these as you have attachment points.

Mine are working well. Nothing bad to say about them at all. Been about 2 years since I installed them on my HTPC, and yep...all is well.
