Larry Ortiz5 said:I have a question for anyone who uses a case where the power supply sits at the bottom. Generally speaking, should I mount it with the fan facing up toward the graphics card, or should I flip it? The user manual for my case shows the PSU mounted facing down, but won't that cause it to choke? Even if the bottom of the case has vents to let the PSU breathe, is it still an issue? Any advice?

I believe they design them that way for cases equipped with dust filters on the bottom and small feet to lift the unit off the surface so it can pull in air without sitting directly on the floor.

In my opinion, you should mount it facing down, but it’s probably best to check with someone who actually has that specific setup. That’s how it was intended to be used, though whether it performs better that way, I can't say for sure. 🤷

Usually, they face down so the PSU pulls cool air from under the case to stay chilled. If it's facing the GPU, I guess it just ends up sucking in all that heat instead...

The PSU isn't blowing air into the case; it's pulling it out.

It’s true—if you think about it, when the graphics card starts pulling heavily from the power supply, and then that power supply feeds back into the GPU, you end up generating a massive amount of heat.

The PSU can't really blow air directly onto the GPU, mostly because the fan is sucking air in rather than blowing it out.

But the power supply might soak up some heat from the graphics card, which probably makes the whole unit run hotter...

But, the PSU can definitely pick up heat from the GPU, which might make it run hotter in the process...

Correction—that's what I meant—the power supply is blowing air out of the case...

You can take the labels and technical specs on some off-brand power supply to the grave for all I care. You really need to rely on actual benchmarks from a reputable testing site that puts these units through their paces. When it comes to those stickers, if you see it’s a Corsair unit, you don't even need to bother looking at the reviews—just pay the premium and get it over with.😁😉

Actually, EVGA isn't some mystery brand either. I doubt they'd just slap fake data on their PSU labels. A German is a German! 😁

Adam Moore3 said:Sure, EVGA isn't exactly some mystery brand you've never heard of. I honestly don't think they would just slap fake specs on their power supply labels like that. When you buy from a German company, you get what you pay for. 😁

I wasn't actually talking about the EVGA unit, I was referring to that other one. EVGA 500 W I'm not quite sure what you're getting at with that, so if you have a specific question or something you want me to look at, just lay it out for me. $90 You can just sit there and wonder what this is even about if you want.🙂I’d honestly rather just grab this Corsair unit from the other link instead. Sure, the 380W rating is a bit on the weak side, but I don't see much point in risking it; if I mess this up, I'll just end up hitting my head against the wall anyway.😂

I found this listing for a 380GB hard disk online, though I can't say much about its current availability or if it’s actually worth your time given how quickly hardware becomes obsolete. It looks like a standard drive, nothing particularly special, but if you're just looking for some basic storage to fill out an older build, it might serve its purpose. Just keep in mind that in the grand scheme of things, capacity like this doesn't mean much anymore when everything has moved toward much faster, larger SSDs.

When it comes to EVGA power supplies, the logic remains pretty much the same; anything sitting below this specific model isn't even worth mentioning, let alone buying, unless you're in a massive bind and money is tight.If you're looking for a high-quality, battle-tested power supply—ideally from a reputable manufacturer—you really can't go wrong by sticking to the big names. The most critical component of any computer setup is... There’s really no point in bringing this up again, especially since I can't even count how many times people have gone out of their way to intentionally ignore it. The golden rule..☕

I took a look at that hardware breakdown on the site, and honestly, it’s the kind of deep dive you expect when someone actually knows their way around a chassis. It covers a decent spread of components, specifically looking at how various power supplies hold up under pressure. They spent some time dissecting the Corsair CX 430, which is a staple for budget builds in the States if you just need something reliable enough to get the job done without breaking the bank. It’s a straightforward unit, nothing flashy, but it serves its purpose for mid-range setups where you aren't trying to push extreme overclocking limits. They also touched on the EVGA 500 W and the EVGA 600 W, which are pretty much the go-to choices for anyone building a solid, dependable PC here. The review feels measured, avoiding the usual hype cycles, and instead focuses on the actual stability of the voltage rails and how these units handle a steady load. If you're sitting there wondering whether to grab a Corsair CX 430 or step up to something from EVGA, this gives you a pretty clear picture of the trade-offs involved in terms of efficiency and build quality. It's a solid read for anyone who prefers facts over marketing fluff.

I can't really do much with just a link to a product page. If you want my take on it, you're going to have to actually say something first. Give me some context or ask a real question.

It's the same deal with EVGA power supplies.

Are you kidding me? 😁

All you really need is a killer GPU for a couple bucks. As long as you've got a decent enough power supply, you're set. 🤣🤣🤣

The main thing is just getting a killer GPU for the price of a couple of beers... a decent enough US power supply will do the trick. 🤣🤣 🤣

There are even cheaper options out there like Codegen, Neon, or Frontier, etc. You can spot them by those crazy low prices around $20 for 400 or 500W units.

Folks, the man said it all. 😬 I Fl@tron, I really hope that having an MS power supply was just a total fluke, because I happened to deal with one of those exact same ones by pure coincidence. 🙈

Honestly, I'd much rather spend an extra 100-$50 on a used Ford Mustang (or something similar) than deal with a brand new MS Dreck.

That was sarcasm. 😬

I never buy garbage power supplies. I’d much rather save a few bucks and go with a slightly weaker CPU or GPU. But I don't skimp on the PSU, and I don't skimp on the motherboard either.

Look, I get what you're saying, but I’m talking about the big picture here. When one of my buddies tells me their power supply just kicked the bucket, that's usually exactly what I suggest they do. And honestly? I'm right there with you. Wouldn't it be better to just scrape together another hundred bucks and do it right the first time? $67 So, how much should you actually spend on a power supply if you want it to last? I mean, are we talking about buying something that works for the next two years, or are you looking to build a rig that stays relevant for five or more? It’s a real question, isn't it? Should you just grab whatever is cheap right now, or is it worth investing upfront to ensure you aren't swapping parts out every few months?👍

Hey everyone! I’ve been lurking here for a while and you guys are awesome. Since we're talking about power supplies, maybe someone can actually help me out for once, haha 😁

So, I'm setting aside about $933 for a new build.
I've pretty much picked everything out except for the PSU.

What kind of power supply would actually fit this setup?

ASRock B75M 1155 2x DDR 1600MHz
Intel Pentium G860
WD 750GB 3.5'' Hard Disk
Sapphire 6670 1GB GDDR5
RAM: 2x2GB 1600MHz Corsair

(Gonna just grab the cheapest case and CD-RW I can find xD
The whole rig is just for browsing and some light gaming—nothing crazy, obviously. hh)

Anyway, thanks in advance for the help.

So, what are you actually looking to buy? Tell me that and I might be able to give you a recommendation.
Maybe something like a Corsair CX 430, a Silverstone Strider, an EVGA GP3 series, or an EVGA RedWing, I guess.

Also, grabbing an APU—you know, an AMD chip with integrated graphics—might not be a bad move. You basically get a decent Quad-core processor and a GPU that can handle games on medium settings.

I’d probably just go buy an AMD.

Honestly, I'm even low-key considering that AMD processor option, haha.

Thanks for the help, guys... I think I'll go with the Corsair CX 430 and grab that AMD processor, haha.

Seems like the smarter move. If I'm remembering right, I can always swap in a beefier power supply and a better GPU later on if some crazy demanding Need for Speed title drops, right? 😁

I'm no hardcore gamer, but I love jumping into a good racing game now and then.

Thanks again!

This is how I'd do it:🙂
You've got a decent case😁 with two fans built-in, and that power supply is more than enough to handle a card like an AMD Radeon HD 7850. 🙂
