PSU provides 2 x 6+2... but split?

[PiMaker]

Hello everyone!

I have decided that it's time for a GPU upgrade, a 1080 Ti is the model of choice. I have a 600 W PSU from Cooler Master, good enough I assume. Most cards have either 6 and 8, or 2x8 power connectors, which also seemed fine to me at first, considering my PSU has two 6+2 connectors.

I have just discovered, however, that those connectors are actually coming from one 8 pin cable being split. I have read some terrible things about splitting GPU power cables, so I'm a little bit worried: I know most people say it should be fine if all cables involved are native to the PSU, but then again, just connecting two 8 (actually 6+2) pins to one line?

Is this configuration ok? Should I maybe try and go for a 6+8 card just to be safe? Am i overreacting?

I don't really want to upgrade my PSU, if it isn't completely necessary...

[ There is also one additional 2 pin connector (not in the image) coming directly from the PSU, no splitting. So it's basically 2->2 and 6->(6 and (6+2)) if that makes any sense.

Thanks in advance,

PiMaker

While it's generally fine, it depends on the quality of the PSU. There's a wide variety of Cooler Masters from excellent ones like the V series (I don't think they have a 600W though) to ones that I would definitely replace if I spent $700 on a GPU, such as the b600 or the GX lite one.

if you dont have a "V" or "VS" model cooler master then you need a new psu

most cooler master psu's are garbage or near garbage



dont risk a 1080 ti

Yes you can just use both cables. Many PSUs commonly have PCIe cables split like that, the downside is that the wires and connectors may get hotter since there will be more power from it being split. However, PSU engineers should take this stuff into consideration and will often use thicker wiring for the main part before it splits. But you never know, depends on the quality of your power supply. But in general the power supply came with it split so it's clearly intended to be used in that matter, so I would not worry about it. They manufacture it this way most likely to save money on wires, and it also requires less cables to be soldered down inside the PSU itself.

Just checked, I indeed have the b600 (I bought that thing a while ago... Guess I wasn't wise enough to use the internet back then). Alright, time for a new PSU, I'd rather not take the risk.

Thanks everyone!

The B600 is an okay PSU actually. Well, except for the caps I believe. Let me try to find a review.

If it's fairly new he could get some use out of it if he wants to. It has a 3 year warranty, it's not like it's just going to instantly die in a second because it has some cheap caps. They just won't last as long. If they fail then it shouldn't be hard to figure that out, he could replace it then if he wants. The fan also seems to be something that may last longer than a typical sleeve. Chances are the fan is quite powerful and keeps those caps cool. The min RPM of the fan seems to be 850.

If it were me I agree I'd get a new PSU.

if he was getting something like a gtx 1050 or whatever then sure... Toss your cares to the wind


we are talking about a 1080 ti however XD

/shrug



Its like buying a mclaren f1 and then putting 20 dollar chinese tires on it...

Well, general advice aside, mine is 4 years old in november, so no warranty and probably also due for a change anyway. I'm just lazy and want to avoid running new cables... It served me well though.

Any advice for manufacturers where "everyone" (as far as that's possible on the internet) agrees they're good?

Oh, and I totally agree, not worth the risk on a high-end card.

If it's that old get a new PSU for sure.

Also why focus on some manufacturer rather than focusing on just getting a good PSU for your money?

As others have suggested, the main reason I'm suggesting a replacement (if it was that line) was the investment you have in your GPU. If you had a 750ti in there or something, by all means, it'll work fine. But with the amount you've invested in one of the very top GPUs available, I'd rather just get the cleanest power I can, with a PSU that ought to last for a decade. Would also give you peace of mind - you clearly cared enough to ask about the wiring issue at the start, after all.
