Which PSU should I buy?

Andrew Cooper23 said:Thanks, man.

Since I already dropped some cash on $60, I suppose I might be willing to shell out another $67 just to get some actual silence 😉

The only real issue is whether my local shop even carries Corsair—and if they do, I wonder what kind of markup they'll hit me with

Anyway, thanks for the input... Best regards.

Haha, I get where you're coming from, man.😁😁
The issue is if I pick up a power supply at one shop for $60:
-- and the damn thing doesn't work..
== you might be able to swap it for a better, quieter model right there if they have it in stock

But if they don't:
== then I'm stuck buying the other one from a different store for $127, while the first one just sits in a drawer for $180, whatever.
-- which is a lot $187 for a power supply

I'd survive either way, I guess, but I'm just saying—for now, I need to see what this specific store I visited yesterday actually has on the shelves 🤷🤷

Thanks again 👍👍

Quick question
Regarding the Corsair HX650, the TX 650, that EVGA 650 W unit, the XFX 650W XXX Edition Modular PSU, and the Antec EarthWatts EA650-EC 650W with Active PFC—I was wondering, what are the actual 12V rail limits on those?

Every single one of these power supplies uses a single physical RAIL, and honestly, the EVGA is easily the best value you'll find among them.

This is total garbage

Honestly, I have no idea why you're even stressing over this 🙂

By the way, just to follow up on my previous point: the Corsair TX 650 is actually a much smarter buy. It’s priced right alongside the EVGA unit, but you get a much better warranty—five years, to be exact.

Lately, the main difference between power supplies with a single 12V rail versus those with multiple rails usually comes down to how they handle the default overcurrent protection settings. Basically, it's just whether the unit shuts itself down if a specific current limit is hit on one rail or across several.

Bottom line? You aren't gaining anything or losing anything here. In all my time, I haven't seen a single standard PC build capable of actually tripping that kind of protection and shutting the whole system down. 🙂

I ended up picking up the EVGA, and I guess my PC feels a little smoother now.

We'll just have to see how it actually holds up once I get into a game.

I have no clue what kind of rig we're dealing with here, but honestly, it shouldn't be an issue at all—especially since he absolutely crushed it on the benchmark.

Great build quality paired with a pretty reasonable price tag... definitely a solid pick 🙂

So, I'm kind of wondering... should I grab the Corsair VX450W or just go with the VX550W for this specific setup?

450, unless you're planning on pushing those clock speeds way past the limit.

The VX450 is more than enough... LINK

Just keep in mind that those newer ATI cards pull significantly less power than the older generation of NVIDIA cards...

Honestly, I’d just ignore all that talk about needing exactly 200 watts for gaming. It’s probably better to just grab a 550W or 650W unit, because you really never know what might happen. If you're planning on doing any serious work or overclocking, you're going to need that extra headroom. Even if you're just running things normally, having a beefier power supply is usually smarter than having one that barely meets the minimum requirements. My philosophy is basically that having too much capacity doesn't hurt anyone, and it won't break the bank either. If you have the cash right now, I’d say just invest it; who knows how much prices will jump in a month, let alone six months from now? It’s true that prices can drop eventually, but here in the States, it feels like everything just keeps getting more expensive.

The VX 450 is proven to push over 550W, while this build pulls maybe 200-something during gaming... isn't that plenty of headroom? 😁

You could definitely roll with the VX 550, but that thing actually delivers north of 650W... which means you’ve got a 400-plus watt buffer.

They'll have plenty of extra left over for export, haha.

Hey Alexander Martinez, if you take a 450W unit, you're probably looking at 550W, and a 550W one might give you 650W. From what I recall, and from reading a few Corsair reviews, the absolute peak power they managed before everything just gave up was under 500W for the 450 model, and maybe under 600W for the 550. If you try to push it 100W past the rated max, I guess you'll just fry the whole thing in an instant.

Heh, it’s a Seasonic, isn't it? CWT... they actually include overcurrent protection 😁

Anyway, here is the actual test for the VX 450.

As for the VX 550, word on the street (from my local "sources") is that it can handle an overclocked Intel Core i7 920 paired with three overclocked HD5850 cards. It even handled three 8800 Ultras and three 260 GTX cards without breaking a sweat... that unit must have some serious wattage under the hood 😁

The VX550W is honestly a fantastic piece of gear. Between the benchmarks I've looked over and my own hands-on testing at home, it holds up beautifully—it just works. Huge props to CWT and Corsair for putting this together 🙂

I mean, I’m probably just gonna grab the VX550 since you never really know if you're gonna end up overclocking everything or maybe even throwing another GPU into the mix for a CF setup later on... the difference is $40 not that massive anyway

Smart move. Plenty of good hours ahead for just sitting around and staring at a computer screen.

Anyone know the power draw on a 5850?
