Molex to ATX 4 pin

Recommended Posts

Posted · Original PosterOP

I bought a Thermaltake Litepower 650w for my new build:

 

Gigabyte Z390 UD

I7-9700K

EVGA RTX 2070 XC

 

So, everything ok untill I realized the motherboard had a 8+4 pin, but the PSU just has 1x 4+4 pin. Reading around I notice you actually can use this setup with just the 8 pin without using the extra 4 pins. The thing is I want to OC, not heavy, but maybe 4.9Ghz.

 

I came up to this adapter that converts a molex cable to a ATX 12v. My question here is, is it safe? I know I should get a 2x8pin PSU, but I can even find one with less than 1000w (overkilling), thats why I came to this.

a litepower on that hardware? please get a different one. You can overclock pretty well without that 4pin, you should even get your needed overclock with the 4+4

whats wrong with the litepower and if im able to reach 4.9Ghz without the 4 pin, whats the 4 pin made for?

Because the Litepower is super low end and super crappy group regulated PSU. 

The extra 4 pin is marketing. It's as useless for performance and overclocking as RGB.

I think the hoomans put their builds here?

Why do you hoomans give your builds a name? Here's my build, which I shall call "Do as I Say, Not As I Do" (seriously, don't get this build)

Spoiler

Ryzen 1500X @3,925 GHz

Cooler Master Hyper 212 Evo + 2x ML120

MSI B350 Tomahawk Arctic

2x8GB Corsair Vengeance LPX 3000 MHz CL15 (Micron B-die) @2933 MHz

Sapphire Radeon R9 280 Dual-X @1120 MHz / 1450 MHz

120GB 850 Evo

120GB Kingston SSD

500GB WD Blue

Cooler Master Elite 430

Seasonic Prime Titanium 650W

Logitech G710 with Kailh Box Jade

Logitech G502

HyperX Cloud

And my laptop, which I shall call "If It's Stupid But It Works" (It can actually play CS:GO at 50 FPS, and Civ V at 25 FPS)

Spoiler

Lenovo Thinkpad L460

Intel Core i3 6100U

4GB (probably) DDR4 2133 MHz

Intel HD Graphics 520 0.3-1.0 GHz

128GB Samsung MZ7LF128HCHP

Corsair M65 Pro RGB (worst mouse I've ever had)

Sennheiser CX 5.00G

And here would be where I would put a picture of my cat. But apparently, images are not allowed here. So take this instead (*ΦωΦ*)

For extra power delivery when overclocking heavily. It's a low quality psu that shouldn't be combined with such expensive hardware

The extra 4-pin EPS on current motherboards seems to really only help some extreme LN2 overclocking scenarios, though for LN2 other board features are also needed/nice. Single 8-pin is more than fine for your use case even if on a custom loop; you'll be held back by temps before you run into any potential voltage drop due to the connectors, and possibly even before the 'not as clean' power signal from your current 'low quality' PSU. Though, for your CPU and GPU, it makes more sense to power them from a tier 3 or better PSU from this list.

Nice explanation, so 4 pin is not a problem now. I will consider changing the PSU with one of those. Thanks

Is anyone going to use a $120 board for LN2, though? Probably not. So it's useless.

Hence the mention of "other board features" in the end of the sentence you excerpted from. Absolutely a marketing point for a number of recent boards, yes.

is it way too overkill to consider a EVGA G2 or GQ 1000w? (considering long term upgrade to 2x RTX 2080 NVLink)

It'd be overkill imo, as you'll do fine with 750W and 850W options as well, but up to you really.

That's too bad.

 

Now turn around and return that PSU and get a proper power supply.
