Making a new PC build and looking for the best power supply that you can get? You should! The PSU is the heart of your computer. It’s responsible for providing stable power to all your components at all times.
That being said, it goes without saying that this is the one component that you should never cheap out on! So, let’s take a look at the best power supplies that you can get right now, shall we?
1: Best Power Supply in The Budget Range: Corsair CX550
Lots of PC enthusiasts may tell you that the Corsair CX series should be avoided. But, the truth is that it has served thousands and thousands of people with little to no issues.
Add that to the fact that numerous reputable/experienced reviewers like Linus and JohnyGuru have said good words about it, and you can see why we picked this as the best power supply that you can get at the budget range.
The CX 550 is 80 Plus Bronze certified which means that it’s at least 82% efficient at 20% load, 85% efficient under 50% load, and 82% at 100% load. That being said, 550 watts is definitely more than you’ll ever need for a budget system. But, it’s better to have a bit more room for upgrading and for playing it safe as well.
Regarding the specifications, we’re looking at a full-wired setup, 5 SATA cables, 4 PATA connectors, 2 PCI-E connectors, and the standard stuff.
Now, the full-wired setup can be a bit of a pain for cable management. But, we’re talking about a decent budget PSU here. We can’t have everything at this price range.
The 2 PCI-E cables are definitely overkill and we wouldn’t recommend actually using 2 GPUs on this power supply. Corsair themselves are saying that this is not multi-GPU ready. So, not sure why they added 2 PCI-E connectors.
If you’re living in a rather hot room, do keep in mind that the maximum operating temperature is 40-celsius degrees.
2: Best PSU For Mid-Range Builds: EVGA Supernova G2 (650)
By moving on to mid-range builds, the power demands only get higher and so does the need for a more efficient and cooler, no pun intended, power supply. Thus, we’re moving from a 550-watt 80 Plus Bronze rated PSU to a 650-watt 80 Plus Gold rated one.
Speaking of 80 Plus ratings, the Gold rating of the EVGA Supernova G2 means that you’ll be getting at least 87% efficiency or 90% depending on where you live. Oh, yeah. According to Wikipedia, power supplies seem to be more efficient on 230V EU plugs. Not a big deal, though.
As mentioned before, this is a 650-watt power supply. This should be more than enough for a mid-range build which gives you room for upgrading towards the higher-end spectrum and maybe even use dual-GPU setups. After all, according to EVGA, this is SLI and Crossfire ready.
Moving towards the connectors, there are:
- 9 SATA ports divided into 3 cables
- 6 four-pin peripheral connectors split into 2 cables
- And 4 GPU connectors split into two cables with one of them offering a couple of 6-pin connections and another one offering two 6+2 connections
The EPS and ATX cables are a given so we’re not even going to mention those… even though technically speaking we just did.
Last, but not least, this is fully modular and comes with Japanese capacitors on the inside with 7-years of warranty. To summarize:
- Good cable management? Check
- Good price? Check
- Reliable and quiet? Check
Overall, we do definitely consider this as the best mid-range power supply that you can get – or at the very least one of the best!
3: Best High-End Power Supply: Corsair RM 650X
At about 60 dollars more than the EVGA Supernova, the Corsair RM650x offers high-end performance for not a whole lot of money. It’s still a bit expensive, but not so much compared to other high-end models.
“But, WTLS! This offers the same wattage as the previous choice and even the same efficiency level. Why should I pay more money for the same thing?” Good question, fellow reader!
While on paper, both power supplies look identical, the RM650x is often placed on a higher tier level by enthusiasts and pros and is often deemed as a bit more reliable choice. So, who are we to speak against them?
Now, of course, we’re not saying that the Supernova G2 is a bad choice for high-end builds. It’s actually still a great choice. But, if you’re making a brand new build, consider spending the extra money and getting something a bit more high-end like this one.
Again, as we mentioned above, the RM650x is very identical with the Supernova in terms of on-paper specifications:
- Fully modular
- Fanless operation in low power draws
- 80 Plus Gold rated
- Full Japanese capacitors
- 10-year warranty (3 more years compared to EVGA)
- Same number of connectors and multi-GPU ready
Overall, we’re looking at a high-quality PSU here that’s been approved by both thousands of users and pros. It’s hard to go wrong with it and we consider it the best power supply for high-end builds.
4: Best Power Supply For Enthusiasts: Seasonic Prime 1000 Titanium
So, this is obviously not targeted towards your average consumer. No “normal” gamer, professional, or any PC user who actually utilizes his computer like a normal person will need a thousand watts of power.
If you’re into mining or you got multiple power-hungry GPUs running at once? Sure. You can utilize it. For the rest of us, chances are that there’s no need to go anywhere near something like that. There’s a reason that we ranked this as an “enthusiast” PSU. Still the best power supply on this category or at least one of the best.
As the name suggests, this offers Titanium efficiency, meaning that you get at least 92-94% efficiency which wastes little to no energy in waste heat, and also up to 1000 watts of power. Obviously, all of this costs quite a lot. More than twice as much compared to our high-end recommendation.
Specification wise, you get all the goodies that our previous two recommendations offered along with even tighter load regulation. Fully modular setup, fanless mode up to 40% power draw, multiple connectors for GPUs, drives, and peripherals, etc.
Overall, it’s simply one of the best PSUs that you can get in the enthusiast range. And in the rare chance that even a thousand watts are not enough for you, there always choices like the Corsair AXi 1600 (stay away from the 1200i model – too many negative reviews).
That’s all for now! Hopefully, you managed to find your pair. If you’ve got any questions, let us know about them in the comments section down below!
