Which PSU should I buy?

Do you have a specific budget in mind?

One of the more affordable yet reliable power supplies would be this https://www.amazon.com/s?k=hex+400w

Keep in mind that you could reuse the PSU in a future build, so let me know if you're willing to invest a bit more.

Which one’s actually cheaper? I’m thinking about using this rig here and there, nothing crazy—it won't be running 24/7 or anything. What do you think about grabbing an Elementum E2 power supply instead?

It's slightly lower tier than Hex, but it'll work. Just keep in mind you won't find it at any standard US retailers. Plus, it isn't actually that much cheaper, so your best bet is honestly just sticking with Hex.

And this?

It’s from Elementum and Hexe, but it should be fine. Though, neither the Core 2 Quad nor the 7850 are exactly low-power office builds...

It's fine for an old rig, I guess. At least for that price point.

It’s a solid deal; those latest LC Power office power supplies are actually quite decent for the price point. Of course, the "sale" is just marketing hype since it was never even priced at $110 😁

True, but $49 is also dirt cheap. For that kind of cash, you're basically buying a "please explode my PC" special 😬

This should handle an average PC setup without any issues. For instance, think about a mid-range CPU like a Ryzen 5 or an Intel i5 paired with a GPU such as a GTX 1650 super or a 1660 super.

Hi everyone, I was hoping I might be able to get a little bit of guidance regarding my power supply setup.
So, I recently picked up a new modular EVGA SuperNOVA unit, but it seems like the packaging only included a single PCIe cable for the GPU. I’m actually trying to hook up a second graphics card—an ASUS GTX 1070, specifically—but I realized I'm just one cable short to get everything powered up properly.
My big question is, I guess, would it be safe if I tried using a cable from a different manufacturer (I believe it's an XFX one) to bridge the connection between the PSU and the GPU?
Thanks so much in advance for any help you can offer!

Not a chance. Pin layouts on modular power supplies aren't standardized, so you might end up with the plus and minus swapped, which would probably just fry your components.

I just picked up a new EVGA SuperNOVA modular PSU. The box only came with one PCIe cable for the GPU. I’m trying to hook up an extra card—an ASUS GTX 1070—but I'm short one power cable.
Is it safe to use a cable from a different brand (looks like it's from an XFX unit) to connect this PSU to my GPU?
Thanks in advance.

Too easy. Just return the PSU if they didn't include the cable that was supposed to be in there. Otherwise, you could always try making a PCIe adapter from a Molex connector.

The site says it only comes with one SATA cable. Kind of a joke, I guess.

The site says it only comes with one daisy-chain cable. Pretty useless.

2 x 8-pin PCIe connector ("700mm / 150mm")

If it's just one cable and the issue is that the 150mm stretch is too short, you can always extend it. Honestly, it should be enough length to reach from one card to the next. Unless the first card already needs 2x8-pin, but the OP didn't specify.
Either way, you can just grab a Molex to PCIe adapter and use the
3 x 4-Pin Peripheral connector ("600mm / 150mm / 150mm")

I really want to say thanks to everyone for all the helpful replies! So, here is the situation: I already have two cards hooked up to my current cable, which means I just need to connect one more card—and honestly, nothing else besides the GPU is pulling from this power supply. I'm working with three ASUS GTX 1070 units, and since their maximum draw is about 150 W, I figured that with an 80% efficiency rating, this power supply should technically be plenty strong enough. Unfortunately, my old unit finally gave up the ghost, and I guess I made a pretty silly mistake when I was buying the new one by not checking exactly how many cables come in the box. I feel like I’ve practically scouted out every single Best Buy and Micro Center in the metro area, but I haven't been able to track down an original EVGA SuperNOVA cable anywhere. Does anyone happen to have a recommendation on where I might be able to pick up a PCIe cable specifically for this model? I wouldn't even mind something used, as long as it's the right fit.
P.S. I'm a little confused as to why the power supply features three separate slots for CPU/PCIe connectors if they only include one cable for each.

Just grab two Molex to one PCIe adapters and you should be fine, I guess.

fadedorca66 said:Just grab two Molex to 1x PCIe adapters and you're good.

Yeah. Each Molex provides 75W. You can make a 6-pin out of one, or an 8-pin PCIe from two. If the PSU puts out roughly 600W on the 12V rail, it can pull plenty more from the wall. It should be fine. Obviously, depends on what else is pulling juice in the build.

(nothing else is running on that PSU except the GPU)

Alexander Moore67 said:(nothing but the GPU is running off that PSU)

Oh, so you’re using some kind of dummy ATX adapter to trigger the PSU through the motherboard since the rig is running dual power supplies? My first thought was that the main PSU handling the motherboard might just handle that third GPU too, without needing extra adapters.

Those are just crypto miners 😁
Yeah, they use all sorts of weird adapters and setups, so one PSU might trip while another stays fine and stuff like that.
But yeah, 2x molex should handle that load without any issues, I guess.
