Just looked it up, you can use a p4 or p4+4 for the extra 4pin on the ch6. I really don't think its necessary and pretty sure most of em don't even have it plugged in.

kk thanks,

I just noticed (while i was looking) that i had the 8 pin ATX power connector (for mobo) plugged into a PCI-E power slot on the PSU instead of the one listed "P8".

It's a 10-pin on the PSU side

The p8 port is 10 pin.

It's been running like that flawlessly for months though. (with two free pins completely uncovered as PCI-E is 12 pin)

Just switched it over. Works fine, too.

Tried disconnecting cable completely (removing the 8 pin ATX connector from mobo) and system wouldn't boot. (it would power up for a 0.5s then power down)

So it must have been absolutely fine to run it that way. (8 pin ATX mobo connector for CPU) off a PCI-E

Anyway, now that thats fixed:
the 'P8' 5-pin (PSU side) to 4+4-pin (MOBO side) ATX motherboard connector, must be the one I am missing.

I've emailed the supplier, hopefully they'll just post it out to me.

I do Dry Ice e.t.c so I may need the power.

Even so, I still think its a bit of an advertising gimmick.

Consider this:
220w FX 9590 @ 8.5GHZ

95w 1800x @ 5.8GHZ (world record under LN2)

Obviously the 9590 would be consuming tremendous amounts of power in comparison. But didn't need the extra 4 pin.

Finally got my Evga Bracket for My CLC 280 Cooler and have spent a few mins OCing my Ryzen 1700 on My Giga x370 gaming 5. Results and voltages as follows.

4.0 Ghz all cores And memory running at 3200 c16. Mem voltage 1.37, SOC voltage 1.22(reads as 1.88 in HWINFO64), CPU Voltage 1.44. Cinebench Scoring 1772 And CPU reaching 63.5C under P95. Very happy w my $329 gem wink.gif

It's more than a gimmick.

If your PSU doesn't come with two 8-pin EPS, that's just bad to begin with. But that's not the end of the world.

Mobo EPS is just an inverted PCIe Power on mobo's end. A simple rewiring and/or PCIe to EPS converter will do the job.

Just because it isn't needed does not mean it's a gimmick nor that it won't help. I just saw a user melt a plug in another thread. If he had another eps (even 4 pin) this would not of happened. Electricity takes path of least resistance. The connector melted due to hear, due to resistance caused by a loose connection. Had another esp been plugged it, the electricity would of flowed from the "extra" as that would s be a lower resistance

Afaik, motherboards tend to have an extra power socket for the cpu, in addition to the 8pin one. This additional socket isn't necessary to use for regular overclocking, but is afaik instead used for extreme overclocking.

4pin is able to deliver 144W compared to 8pin which could deliver twice of total power. it's fine for ryzen cpus to just use 4 pin actually. but, spreading the load to 8 or even more pins is better. you'll get lower wire and socket resistance. you'll not need it for daily use but might be good to plug everything if your PSU have another 4pin CPU plug biggrin.gif

That is a tremendous amount of power capability.

The main 24-pin connector can supply 560 watts alone.

The 8-pin auxiliary can supply 528 watts.

Thats 1088 watts

A further 4-pin auxiliary connector would supply an extra 264 watts.

In total that equals 1352 watts!


GPU's only pull 75 watts from the mobo, two in SLI would draw 150w

Thats leaving 1202 watts just for the CPU, memory, drives & pumps/fans etc.

I can't even begin to think of a scenario where a motherboard needs more than 1088 watts (24-pin & 8-pin).

What could cause a 1352 watt draw (requiring an additional 4-pin) when there is already a 24-pin & 8-pin?

I am intrigued, lol.

the answer is actually written on my post above. to spread the load across the wires, traces, and sockets. more wires means less resistance which means less power loss which means less heat

I hear ya, but wouldn't you need to draw more than 1088 watts, until the cable even begun to heat up? (24-pin & 8-pin auxiliary).
