Corsair RMx Series, RM1000x, 1000 Watt, 80+ Gold Certified, Fully Modular Power Supply (CP-9020094-NA)

You could have the highest end GPU, the top of the line CPU, a motherboard for the ages, and all the hard drives you will ever need, but all of that won't do you a lick of good if you don't have power going to it.That said, not all PSUs are built the same and if you cut corners by going for a PSU from an unknown company or knockoff, well, you'll probably gonna have a bad time.I got this PSU because it was the best balance between quality and price I could find. The RM750x 80+ Gold Certified specifically. As a general rule of thumb, you want a PSU with twice the watt capacity your entire build uses, both for futureproofing and to make sure you have the power you need. For most people, 550 watts will be more than enough, but the 750 watts I have will allow me some wiggle room for future upgrades. The watt capacity you want to use will depend on your build. Most people won't ever use anything higher than 1000 watts, but if you have a high end build, for example a Threadripper CPU and one or two 2080 Tis, get as high a capacity as you can afford.Energy efficiency isn't as important on a desktop as it is on a laptop (because battery), but it can make a difference for your electrical bill. Not a huge difference, but a difference nontheless. For most people, I'd recommend 80+ Gold as it's a good balance, though if you have the money you could splurge for a Platinum or even Titanium. If you want. I'd also recommend going for a fully modular PSU whenever possible, which this one is. It's better for cable management more than anything else, which aside from air flow, also impacts organization when you have to sift through cables.There really isn't much else to say, if you don't want to go for EVGA for whatever reason, Corsair is a good alternative.

A good PSU is one that does its job and goes unnoticed and that's exactly what this PSU does. I upgraded from a 500 watt evga bronze PSU after my 8700k upgrade and while the 500w evga was probably enough, I wanted something modular for cleaner cable management and the all black cables of this PSU were also a huge plus as they're much nicer looking than the mustard and ketchup colored ones of my old one. My old PSU was somewhere around $30 when I got it a few years ago and with this one being at around $100 dollars you can see the difference in quality right out of the box, it just has a high end look and feel to it with the packaging and everything. I can't attest to the actual quality of the internals but the general consensus around the internet is that you do get what you paid for in terms of the components that this PSU is made of. I read somewhere that the older RM series used high quality capacitors for the main caps but lower quality secondary caps, while the newer RMx line uses the same high quality capacitors all throughout. I guess this PSU also comes with a 10 year warranty, which is reassuring as you usually don't see warranties span that much time and most people probably usually don't keep the same computer hardware that long anyway, though I definitely think that this PSU will be able to last through several builds. As for the 0db fan, I don't think my old PSU had that feature, but honestly I could never hear the PSU fan over the case fans at low load, and at high load my GPU fan would drown out any other noise.

I purchased this PSU as an upgrade from the factory unit in my Dell Optiplex 7010 MT. If you are looking to put one of these in this same type of PC, a word of warning: this PSU barely fits. I thought I would actually have to return it, but I was able to squeeze it in while sliding the side panel latch forward. Luckily, the latch still moves back enough to allow the side panel to stay closed, but the latch does rest against the PSU.Aside from that, I really like this PSU. The cables are a bit stiff, as some have stated, but I found that they hold bends really well because of that. This is definitely suited for a larger case, given the size of the unit and the actual cables. It was a tight fit to route the cables around some of the hard drives in my mid tower. At normal load, the fan doesn't run at all. Until I put a GPU into the PC, I don't think I will ever see the fan spin up. One of the reasons I opted for this unit is because of how many SATA cables it has. If you are building a media server, it's a great option since you can attach plenty of drives to it.Overall, I would definitely recommend this PSU.

I purchased this for a 2014 Dell XPS 8300. Its original PSU was rated at 460 W, but I wanted to go a little higher because I plan on buying a new GPU soon. I've been using this system with the new PSU installed for a week as of writing this review, and so far I'm very happy. The fan works great - it's quiet and when it turns on, it's powerful. It combines well with the case fan. I've had no issues what-so-ever and will be back here to update this review if anything changes.Update (Feb 2020): Still no issues. PSU working just fine. I installed the new GPU (MSI NVIDIA GTX 1660 Ti Gaming X) and believe it or not the system works. Now, the system does experience regular crashes when skipping while watching videos with the new GPU (that's probably due to the the Dell bios not being up to the task). For all other tasks, including kids gaming (Roblox, Minecraft, Fortnite, GS:GO), there have been no issues and the PSU is supplying ample power to the cpu and gpu for this old Dell system. I keep the 5-star rating for this PSU.Update (August 16, 2020)No issues at all. On a related matter, the regular crashes on skipping videos after installation of the new gpu as discussed above have completely stopped for some reason. System is working like brand new, and the PSU is still quiet and efficient. Still happy with this purchase.
