Power supplies. They’re the one component that not many people take a look at when it comes to building a brand new PC. Here we have the SilverStone ET650-B – a power supply that is budget-oriented with 80 PLUS Bronze certification. Let’s have a look at what the SilverStone ET650-B has to offer.


What’s more exciting than an unboxing of a non-modular power supply? Nothing, actually.

SilverStone ET650-BAround the box is where the specs are located, as usual. One thing it did show on the box is the length of each cable. For those who don’t want to buy extension cables after buying this power supply, measure the lengths needed first. Of course, only a niche segment of users actually do that.

Its efficiency and fan curve are also printed on the box.

It’s pretty standard for a power supply to come with padding, a user manual, a set of 4 screws to mount it to the case, and the bundle of cables coming out from the PSU parked beside the PSU itself. Oh – there’s also a C13 power plug in the box. Nothing out of the ordinary.


Here’s where things get interesting.

People aren’t choosing them for its power delivery consistency these days, but mostly for its looks. I’m talking about power supplies with RGB fan. So much so that there are actually people who remove stickers on their power supply.

The SilverStone ET650-B takes on an understated aesthetic with its matte texture, but sort of ruined the sleek aesthetics by stickers at the side. I mean, there are quite a lot of them on the side, too. You can remove them, but it might void your warranty.

Through a tempered glass side panel, this will look rather jarring, in my opinion.

Behind the SilverStone ET650-B is where you’ll find a power button too. It’s not particularly important, but nice to have nonetheless.

Then comes to the power supply’s cables. It comes out from a single circular hole with all the cables coming out through it.

Here’s the one specialty of the SilverStone ET650-B – flat cables. Actually, a bunch of tiny black cables stuck together to create the “flat cable”, which nicely brings us to the next section – but first, its specs.

The overall specs of the SilverStone ET650-B is up on their website with very intricate details. The gist of it is this:

 Load Range +3.3V +5V +12V1 +5VSB -12V
Max.(Amps) 20A 17A 50A 2.5A 0.3A
Peak (Amps) / / / 3.0A /
Min.(Amps) 0.1A 0.2A 0.5A 0A 0A
Range (%) ±5% ±5% ±5% ±5% ±10%
Line Reg.(%) ±1% ±1% ±1% ±1% ±1%
Ripple(mVp-p) 50mA 50mA 120mV 50mV 120mV

Cable Management

First, let’s take a look at what connectors are available and also its lengths. By looking at these lengths, it’s obvious that SilverStone designed the ET650-B in a way that it’s meant to be mounted at the bottom of the case. I mean, just look at the 4-pin EPS cable length.

  • 1 x 24 / 20-Pin motherboard connector (500mm)
  • 1 x 8 / 4-Pin EPS / ATX 12V connector (750mm)
  • 4 x 8 / 6-Pin PCIE connector (500mm / 150mm x 2)
  • 6 x SATA connector (500mm / 150mm / 150mm” x 2)
  • 3 x 4-Pin Peripheral connector(500mm / 150mm / 150mm)
  • 1 x 4-Pin Floppy connector (500mm / 150mm / 150mm / 150mm)

With all of these flat cables on a non-modular power supply, it’s rather interesting to cable manage this mess. Isolating these cables are easy – except for the 24-pin ATX cable.

This one “cable” is actually made out of 4 different 8-wire cable plugged into one header – thus the creation of the 24-pin cable. This is necessary for flexibility of the cable and it works very well, too.

With flat cables mean it’s easy to turn around corners and to stack them upon each other for cable management (remember, this is a non-modular power supply), but not the easiest when it comes to tying them down to close the side panel. I’m currently using the SilverStone ET650-B in the BitFenix Auora that we reviewed here.

Fortunately, the cables in the SilverStone ET650-B is long enough to route to everything without any extensions, but not too long that it’ll be a challenge to stash those cables somewhere.

Speaking of stashing the cables, its flatness makes it easier to stack behind the motherboard tray – which is especially useful for PC cases with no PSU shroud or basement – but poses a challenge in tying these cables down. Don’t even think about using zip ties. The only solution to tie these cables down properly is by using twist ties.

The best part of the power supply’s cable is the 6+2 pin for graphic cards. There are two different cables for dual-graphic cards setup as it has a total of two double 6+2 pin power for graphic cards. As it uses flat cables, I don’t really have to worry about how it looks through transparent or tempered glass side panels. Don’t have to get cable combs too.

SilverStone took the courtesy to print each cable’s rating on the same side and same orientation too!

User experience

As I’ve said earlier, the SilverStone ET650-B is a sleek power supply other than the part with stickers. In my personal opinion, these stickers will be very prominent when the SilverStone ET650-B is placed in a tempered glass case. However, as more and more cases these days have a basement/shroud to cover it up, this is not an issue.

Here’s the system we tested the SilverStone ET650-B in.

Test hardware configuration

CPU Cooler Noctua NH-D15
CPU AMD Ryzen 7 1700
Motherboard ASRock Fatal1ty X370 Gaming K4
Memory Corsair Vengeance LPX DDR4 16GB
Primary Hard Drive Plextor M8SeGN
Power Supply SilverStone ET-650B 650W
Chassis BitFenix Aurora
Fans Noctua NF-F12
Others SilverStone LS02 RGB LED Strip

The fan is dead silent

The flat cables offer a different experience in this PC build. As I mentioned earlier, cable managing flat cables require some lateral thinking and it’s pretty simple to do once you get a hang of it. When it’s done, damn, the build looks fantastic.

Sure, a case like the BitFenix Aurora that we used here do not have a basement and exposes the main cutout for PSU cable passthrough. That’s where cable isolation and re-bundling them in a nicer order can create a much nicer look overall.

Remember to stack these cables nicely before routing them through the cutout!

Then comes to overclocking. I’m using a system that’s somewhat low-powered. I did try overclocking my Ryzen 7 1700 to 3.8GHz with 1.325V and stress tested it with AIDA64 + GTX 1060 with FurMark. There is absolutely no issue with the power supply at all, and yet it’s still dead silent. I’m sure that the SilverStone ET650-B can handle single-GPU load without any issue too.

Of course, hardware these days don’t take that much power anyway.

Wrapping up the SilverStone ET650-B

To be honest, the SilverStone ET650-B isn’t really available in Malaysia as of yet, but it’s already available in Amazon US for a price of USD $59.99. By a rough translation, it’s about ~RM260.
