Which PSU should I buy?

Frank Bennett3 said:Thanks. 🙂

Where am I supposed to check that...

The light keeps flickering—not constantly, just enough to be annoying. I'm pretty sure that shouldn't be happening.

Either my PC is drawing too much power, or it isn't getting enough. I can't tell which one it is.

Just try testing each cable one at a time in the same spot. If it's overheating, the whole thing is going to cook. Also, try swapping out those power strips for actual surge protectors.

A probe might flicker because of induction—what people call phantom current. If everything else has been running fine until now, I wouldn't sweat it.

It’s impossible to have too much or too little. 😁 It could just be voltage fluctuations that have nothing to do with you or how you set everything up. It’s all about the quality of the power coming out of your wall. That’s exactly why we talk about this stuff here—you need to invest in high-quality power supplies. You want something that has more than just a basic fuse; it needs those extra layers of protection that will actually shut down or even fry itself before it takes your entire PC down with it.

What placidcanyon2 suggested actually makes sense: just lug your rig over to someone who has a solid setup and stable power. You don't even have to bring the whole tower if you don't want to—just grab the case, then use their keyboard and monitor once you get there. See how it behaves under those conditions.

edit:

Installing a power supply... if you're counting labor at even just one hour of service time, you're looking at a minimum of $100.$50Look, here’s the play: you walk into the shop and say, "Hey, I really want to buy this power supply from you guys, but I have absolutely no clue how to install it myself. Could you maybe help me out?" Then you hit them with that innocent, wide-eyed look—you know, the one where you act completely helpless. To seal the deal, just offer them a coffee or a beer on you. Just keep it low-key, though. One-on-one, obviously.

I could use some advice. I’m looking to pick up a new power supply for around $500—well, maybe a bit less than $183—since I don't need massive wattage right this second, but I want to leave room for future upgrades. In this price range, the Corsair STS 600W caught my eye, so I'm curious what you guys think. Any recommendations? Honestly, if there's something significantly better, I might stretch my budget a little more if it makes sense.
Right now, I'm running an Intel Core i5 (3.2 GHz) with integrated graphics on a Gigabyte motherboard, but the plan is to eventually grab something like a GTX 460—I'll post more details on that later—and I'll likely be swapping out both the CPU and GPU at the same time.

I actually looked into PSUs a while back, but had to put the purchase on hold for financial reasons.

An EVGA 450W is way overkill for that CPU and GPU combo.

I need some assistance here.

My previous setup included
-GeForce RTX
-Intel Core i7

I have since switched to
-Radeon RX
-Intel Core i7

I am currently using a 300W power supply.
The system performance has dropped significantly. I need to determine if the power supply is the culprit and, if so, which reliable, budget-friendly unit I should purchase.

My old setup was basically
-GeForce RTX
-Intel Core i7

I haven't touched the power supply, but I just switched over to
-Radeon RX
-Intel Core i7

And my PSU is only 300W
The PC feels significantly slower now—I'm wondering if it's an issue with the power supply, and if so, what should I buy that won't break the bank?

Before you assume it's the power supply, it might actually be the slower processor😁 😁. If the power supply were truly insufficient, the system would likely just crash or shut down entirely.

Here is the situation. I previously used a GeForce RTX paired with an Intel Core i7, and StarCraft II ran perfectly fine
but now that I have switched to a Radeon RX and an Intel Celeron 3.66GHz,
StarCraft II is constantly lagging. To make matters worse, when I revert to my old setup with the Intel Core i7, performance becomes even slower than before.
I HAVE NO IDEA WHY THIS IS HAPPENING!!!

But now that I've switched to a Radeon RX and an Intel Celeron 3.66GHz,
StarCraft II is just stuttering constantly. Now I tried putting my old processor back in—the Intel Core i7—and it actually runs even slower than before.

Maybe you have CUDA enabled? 🤔

It doesn't always play nice with AMD cards. 😬

Could you please provide some clarification on how CUDA works?
What is the procedure to disable it?

I'm on a pretty tight budget, so I was wondering what the cheapest power supply would be that can handle this GPU and an Intel Core 2 Duo? 🙂

Whatever you do, don't skimp on the power supply.

I'm looking for some advice—planning to pick up a new power supply for around $500 up to $183. I don't really need massive wattage right this second, but I'm prepping for a future upgrade, so I won't actually be swapping it out for maybe another two years. In this price range, the Corsair units caught my eye—specifically the STS 600W—so I’d love to hear your thoughts or any recommendations. Honestly, I might even stretch my budget a bit if it means getting much better value. Other models I've been eyeing include the Corsair ZS 650W (by the way, how is Corsair as a manufacturer in terms of build quality?), the ZS 750W, the Corsair VX550, the Corsair TX650V2 (or the EVGA unit that's basically identical to the Corsair one), and the Corsair GS600.
Right now, I'm running an Intel Core i5 (3.2) with integrated graphics on a Gigabyte board, but the plan is to eventually grab something like a GeForce RTX later on—and at that point, both the CPU and GPU will likely be old news.

I actually looked into PSUs a while back, but had to put the purchase on hold for financial reasons... sorry, Admin, for posting this outside the specific PSU thread, but I wasn't getting any bites in the main section.

I’d probably grab this one from Newegg >
or maybe this I actually own that Seasonic unit myself. It’s dead silent, even when my Intel Core i5-2500K is overclocked to 4GHz and my GTX 560 Ti Twin Frozr is pulling its weight (running at 950/4500 core/memory). Honestly, I can’t recommend it enough.

Hi there. I was wondering if this power supply would be sufficient to handle a Sapphire HD 6950 1GB Dual Fan paired with an overclocked Intel Core i5-2500K?

Thanks!

Look, it’ll probably hold up... actually, it definitely will. Your rig likely isn't pulling more than 300-350W, but if I were you, I'd play it safe and go with the 550W unit instead. If nothing else, you'll get less heat and better longevity out of it.

Would this be any kind of improvement?? http://www.newegg.com/p/product/intel-core-i5-2500k/

Nah, that 500W CX unit is actually weaker than the Xfinity 450W one. 😬 If you aren't exactly swimming in cash, you're better off sticking with the Xfinity 450W...

Wait, why is this one a CX-series? Isn't that supposed to be the V2 version with the 80+ certification?

From what I can see over on the adMov page, the CX 430 w and CX 600 w are both V2 versions, but the CX 500 w isn't. 😂
