be quiet! System Power 9 500W

Advantages: - Excellent manufacturer's warranty, compared to competitors; - An efficient circuit based on dc-dc converters is used, while most competitors in this price segment use prehistoric platforms with group stabilization; - Stylish black color, all wires are black with black braid.

Disadvantages: - There is a Chinese fan of the budget segment, which is installed on the cheapest power supplies, hence the noise, besides, at first it will stink quite strongly of plastic; - There is a Chinese elite capacitor at the entrance, however, it is unpleasant; - Some cables are quite short and in general this power supply unit got fewer cables (usually 24-pin + 8-pin for the processor + power cable for the video card and 3 different cables for powering the sat devices, there are only 2 cables for the sat devices and one of them is short ).

Comment: It also seemed that the grill of the fan was protruding unnecessarily, which made it difficult to fit into my case, but this is probably a feature of my case. For the majority, the absence of a third cable for powering drives and a short second cable will not be a particular drawback, since few people use so many drives now.

Advantages: Quiet operation Stability, no drawdowns along the lines Exports the RTX 2070 without problems Good warranty Serviceability without loss of warranty

Disadvantages: Short and very rigid wires Poor-quality connectors, for example, contacts dangle in molecules

Comment: I bought for a budget gaming PC, Gigabyte z370m Core i5 8400, 8Gb DDR 4 2400MHz, 1Tb HDD 120Gb SSD, initially without a video card, waiting for the release of RTX. As a result, I added the RTX 2070 to the assembly and everything is fine, in theory, the block is loaded by 65%, but it does not give a look, does not heat up and, accordingly, does not make noise. In the assembly without a video card, I did not hear any sounds from it, perhaps I was lucky with the quality of the fan, I did not even understand when the computer was first turned on, because the tower cooler is quiet and the power supply unit is silent. In principle, a decent thing for its price

Advantages: 1. Price - power supplies of competitors with similar system parameters and certificates are on average higher or at the level. 2. Certificates - the power supply is certified according to 80 plus bronze standards, which tells the buyer about the quality and the most accurate declared characteristics. 3. The latest power supply standard ATX12V 2.4 (though I do not know what this affects, but God bless him - is and is) 4.Long wires - it is convenient to do cable management, all the connectors are long enough with a margin 5. There are all the necessary connectors for a home PC, all the main connectors are marked - so as not to confuse anything when connecting 6. Very informative and beautiful packaging - it contains all the necessary block parameters 7. Very quiet cooling cooler - although it spins up for a couple of seconds at startup very much - but then it becomes inaudible 8. Protection against short circuits and overloads - in theory, it should protect your hardware from troubles. 9. Braiding of wires with nylon mesh - perhaps for someone it is important 10. Availability on the official website of the manufacturer of a convenient system power calculator for selecting a power supply for it. I highly recommend using it before buying

Disadvantages: Not yet discovered

Comment: I chose the power supply based on the power of at least 500 watts and the length of the wires, since there was already an unpleasant case when assembling the PC - when the wires for the lower location of the power supply in the case were enough to fit in the butt without a management cable. As a result, I bought just an informative packaging - for some reason, many manufacturers do not want to specify all sorts of little things in maximum detail - such as the length of the wires, etc. A plus in the choice was also the presence of a certificate of conformity 80 plus bronze - since in most models of an approximately comparable price category it either does not exist at all, or the certificate is simple. Plus sign - but nice. When assembling, there were no problems - all the cables were marked, the quality of the cables and connectors is very decent (except that the molex was a little upset - because it was not possible to connect it the first time - since the pins dangle a little - but nevertheless everything was connected and works), the length of the cables enough for a cable management with a lower power supply in the case. The truth was not without flaws - at the first start of the computer - for some reason, after working for 5-10 seconds, it simply passed out. The subsequent restart did not reveal any problems. After correcting the shortcomings, the management cable and re-routing of some wires - again at startup, after working for 10 seconds, the computer simply fell off. Restart and subsequent starts were already normal. Apparently, the peculiarity of this model is that it has never encountered something like this before when it was first turned on, or the protection worked. Nevertheless, now - a week after the purchase - there was not a single shutdown.

Advantages: - Appearance. - Braided power cables - Efficient circuit based on dc-dc converters - Quiet in daily work and games - High efficiency of at least 80 for my usual tasks - High quality component base, not counting some items

Disadvantages: And so, what we have here: Noisy fan at maximum speed (to which you hardly need to raise your Power Supply). The warranty is 3 years, not 12 like some other brands. (But this is also such a minus for this amount). Another SATA power cable would be nice.

Comment: For this money it is better not to find it, do not even try. Bet 6 out of 5 for this power supply! This power supply is suitable if you need a good and at the same time not expensive price, if you want to build a PC or a home workstation.

Advantages: In my amateur opinion, this PSU is one of the leaders in terms of price / quality ratio. Outwardly, everything looks very soundly, strictly. The bronze certificate also adds optimism. Braided cables of sufficient length. The packaging separately pleased me, I really love the high-quality wrapped goods.

Disadvantages: The bundles of cables themselves are noticeably harsh. This can be a problem, or at least some inconvenience when using this power supply in small cases. In zalman s3, everything worked out well, although not perfect. In some places, we had to bend the wires strongly.The plastic on the connectors looks deshman, but everything fits together clearly.

Comment: When turned on, the unit makes noise at maximum speed for the first 3-4 seconds, but after that it immediately dies down and is not audible.

Advantages: A combination of price, a more or less decent name (although I found out about the brand just now - I haven't monitored the power supply market for a long time) and a modern platform (dc-dc converters and all that).

Disadvantages: Here people complain about the hard wires. Well, in general, yes, they are harsh. True, this did not bring any particular inconvenience to me. The only thing that somehow hardly stuck the main connector into the motherboard is some kind of miracles, like the additional 4 pins are normally docked, and not climb. Moreover, I did not plug the power supply for the processor the first time: I have not enough space there because of the cooler, but the 4 + 4 connectors turned out to be slightly different lengths (the difference is less than mm, probably, but it did). I would also prefer colored wires in black sheath. Now, perhaps, it is not so important to see where is 5V, where is 12V, and where is the ground, but somehow I got used to the presence of this information. Yes, it is, of course, fashionable - everything is black, but now my case is closed, and before I did not suffer from the beauty of the insides.

Comment: From the reviews, I was aware of some mediocre condensers and a fan. But if in the coming years one should hardly expect problems from the conductors, then the valve strained me at first - there were some slight howling. I even wrote about it here, but now I had to edit it - it turned out to be not in it, since spat on the warranty and tried to change the fan. However, none of the three Cooler Masters was found that worked the same way. One 3pin (the connector somehow fit in, despite the interfering condender) did not start (only from the pusher). 4pin (I had to swap the power pins in it) spun briskly at the start, like the regular one, but then got up (maybe with an increase in the load, it would spin later, but did not check it). To exclude from the suspects in the noise, the second 3pin came up, it did not spin up to the maximum at the start, as it typed, it worked. I lived on it for one day, but did not leave it permanently. after 7 minutes of the nutritional stress test, the OCCT began to rotate very slowly, although the opposite was expected. I immediately turned off the computer, removed the power supply cover with the valve and began to feel the insides. The radiator of the dc-dc converter got hot (the finger did not really tolerate it), everything else is a little warm. On a standard fan, under the same conditions, this radiator could be described as simply warm. And at low loads, in general, there was a feeling that it was possible without a fan, but did not experiment. Now they are no longer afraid that the big conder is 85 degrees. By the way, I unrolled one Foxconn 400W power supply, I thought to take a valve from there for a substitution, but there it was without a connector, but it had the same marking D12SH-12, but without mentioning YATE LOON. I am critical of the noise of the computer in idle and at low loads, the power supply seems to behave decently on them. And I will not be able to load it to the full, tk. even under the stress test i5-2500k (without overclocking) and a bagel on the gtx670, the load is far from complete and the noise is more from the video card. I bought a bp with the expectation that I would hardly put the second vidyuhu anymore. So enough with a margin.

Advantages: - a well-known brand with high-quality components; - all conceivable and inconceivable protection systems for such a budget segment; - light; - works quietly even under high loads; - honest 80 PLUS Bronze.

Disadvantages: - when switched on, it makes a noise for two or three seconds, then dies down; - the processor power cable is short, you need to stretch it before installing the motherboard.

Comment: I'm happy so far.Fully justifies the declared power, protection against surges and overvoltage, cables in a strong sheath. Draws out, among other things, AMD Ryzen 5 1600 and GTX 1660. Noise at start is slight, but noticeable.

Advantages: An excellent budget unit from a renowned manufacturer. 500W is enough for the eyes. 80+ bronze

Disadvantages: Have not found. Cable management could be added, but that would be a different price.

Comment: If you have one video card, then do not chase the power supply unit. As practice shows, more does not mean better. According to calculations, the power of five hundred is enough for the vast majority of simple configurations.

Advantages: Heavy, quiet, bequiet

Disadvantages: not yet

Comment: recommend for 3300r

Advantages: Inexpensive compared to the promise of Active PFC and 80 PLUS Bronze Certification. The power supply provides 87% efficiency at 20% load, 90% at 50% load, and 86% at 100% load. In general, it looks acceptable and weighs a little less than one and a half kilograms (I held the trains when weighing). Lots of SATA, two connectors for video cards. While the fan is quiet. The wires are long in my opinion. It sticks into the mother quite easily.

Disadvantages: Strange, but it smells like plastic. When turned on and used the smell was enough for the whole room. Slowly the smell disappears. all 6SATA and 2MOLEX are on two cables. First 3SATA then MOLEX. I would prefer three branches of wires.

Comment: The computer was powered weak for the test, the fan rotates generally silently. This one, in my opinion, will pull the strongest processor and video easily.
