What's your system specs? Chances are, you'd be fine with a good 650w unit. Probably could getaway with 550w.

It stays in your library. I bought the game RUSE on steam years ago, then they removed it. It's still in my library and playable.

I'm afraid none of those will do. Try looking for a System Power 9, Xilence Performance A+, Pure Power 11CM, or a Corsair CX550. Those are the minimum PSUs I'd use. Also, don't get a 1060 3gb. RX 570 is just as powerful as it and more often than not, it's cheaper. If it's cheaper, then go for it.

I wouldn't touch that unit with a 10ft pole. Unless, of course, I had a load tester to blow it up with ?

Sama has a few good units out there. The Armor Gold is actually quite good. There are a few brands out there some may have no heard of. Some of these brands have excellent PSUs and other times terrible PSUs, that's why you can't choose solely on brand. Hell, even Chieftec has one or two solid units. Look at the model itself, not the brand.

No, it's quite a bad group regulated design. It can only deliver 400w of usable power. Looking at the picture above, it is indeed a group regulated design. According to the manufacturer, it lacks over temperature protections and over current protection. Honestly, I've seen worse designs, but I've definitely seen better. I wouldn't use this PSU. I feel like it's a risk to put a load on this thing with modern components. You're better off saving up and buying a new one, like a Corsair CX550, Xilence Performance A+, or Be quiet! System Power 9.

Well, with a PSU, you really need to know what you're doing to repair one. Corsair is pretty good with their warranties. Maybe try their RMx lineup. If you want to save a little money, their Vengeance Silver is an amazing unit for the price. Alternatively you could go for the Bitfenix Whisper M, which is an awesome PSU, but I am not sure about how good Bitfenix warranty service is.

If you live in the US, they have to because of the “right to self repair” law.

Another PSU to consider is the Bitfenix Whisper M, which is better than the G2 and the RMx.

This is false as it varies from model to model. Some PSUs are most efficient at 30% loads (Like the Corsair AX1600i) and some PSUs are more efficient at 80% loads. There are some PSUs that are most efficient under 50%, but it's certainly not all PSUs. Now this honestly doesn't matter as it's more efficient by a bit less than 1%

12v is used to power pretty much everything on your PC. 5v isn't used as much anymore. I believe it's just used for USB and storage devices. 5v will be found on a good modern ATX PSU. Same with 3.3v, which is even less used.

My personal picks are the Bitfenix Whisper M or the be quiet! Straight Power 11. Both are very solid PSUs and will have no issues powering the PC.

I'm curious since this is a DX12 that this supports crossfire in some way...

Another indication that a PSU is group regulated is to look at the power distribution label. If the PSU says it can output a total a 600w but the 12v says it only outputs 400w, then that's an indication that it's group regulated. Here's some images which hopefully provide additionally clarity to those that don't know. There are two sides to a PSU. Primary and Secondary. Won't go into details on the specifics here, people like OrionFTL and JonnyGuru are better able to explain that if they wish. The two coils boxed in red are located on the secondary side. 12v and 5v are regulated on the bigger coil and the small coil has 3.3v. Now a thing to consider here is that there is a secondary topology known as Dual Mag Amp, which has two magamp coils. Better than group regulation from a performance standpoint, but in general, it's not very efficient. I think the most you can achieve is bronze efficiency. Maybe silver. It can be easy to confused the two topologies. Now, sometimes, group regulation could use one coil. I've seen a few very old PSUs with just the one coil. (credit to JonnyGuru.com for this image.) Below is a Corsair CX450, arguably the best budget PSU on the market for most areas. Boxed in red are the DC-DC converters. Now, this example shows the coils covered. But usually, the coils are exposed and mounted a daughter board(s). These regulate the minor rail outputs while the 12v is independently regulated. I think it's regulated with a switcher or something. Near the transformer. (If someone could confirm, that'd be nice.

Generally yes, I do. However, I sometimes misremember things and I have not looked too deeply into the VS. I just know bits and pieces. I stand corrected. Also, I am named PSUGuru because I am starting up a review site caller that. I am still learning and obviously I need to fact check more before I post.
