Several 350W rated power supplies are recommended

Huntkey Panshi 400 wide king second generation.

Zhenhua Iceberg Kingdee GX430W

Resonant forward excitation unique art (the process is only Zhenhua in the world applied to the PC power supply, this is a very mature current conversion process of civilian grade, our daily electricity, is transmitted through high-voltage circuits, and then converted by a huge resonant positive transformer. On the street, you can see a lot of electric poles with large transformers on them, which is this process).

U.S. 80 Certified Gold Certification.

Conversion rate -- around.

430W rated output. Single 12W output 426W....

Multiple protections. All Japanese capacitors (if you oppose using Japanese products, change one).

The power supply heat is still very small when fully loaded. The ultimate load is nominal 480W....The actual test can reach 560 --580W continuous output.

JD.com** 349, during the special offer.

This is followed by the FSP Black Knight RA 450 ...299 blocks.

FSP's positive pipe process. Last week, this power supply just passed the U.S. 80 certification silver. Conversion rate -- between.

A cost-effective power supply. The capacitors used in the Taiwan series.

Then followed by Haiyun 400w ...80 certified. Bronze.

The conversion rate is around 81% -86%.

Again Antec BP430 ...80 certified. White Label, conversion rate 80% -84%.

Mass production, good stability.

Again. Mozun 400W Antec VP 450W...These two are close to the 80 certified white label standard, but they don't meet the standard.

In the second ...Around 75% conversion rate for Overclocking 3 and Huntkey Multi-Core ...

Again, the domestic Great Wall series. Kanegawada series. Huntkey energy-saving series. The conversion rate is around 72%.

..Worse, domestic copycat brands.

Regarding mute, the power conversion rate is an important parameter. 100W of power enters the power supply, and the conversion rate is 80%, which means that 20W is lost, and this 20W becomes heat, which is to be dissipated through the power supply. If the conversion rate is high, it means that the power supply itself has low resistance and does not generate heat.

There is also some power whine. That's cutting corners on the materials, causing the circuit to emit inductance howling when it enters the capacitor circuit board. This is also a problem with poor quality capacitors...

Generally, the power supply that can pass the 80 certification will not have this problem.

- The above, I hope it will help you.

The following 80plus bronze power supplies are recommended;

1.FSP Black Knight RA450 Power Supply Rated 450W 80PLUS Bronze Japanese 319

2.Delta NX450 Power Supply Rated 450W 80PLUS Bronze 349

3.Huntkey Jumper 450B Power Supply Rated 450W 80PLUS Bronze 299

JD price) hope to help you.

Antik bar, an international brand, the low-end does not shrink, **reasonable.

Antec VP 450P Rated 450W American brand But made in China.

The quality is about the same, and that's what I use.

Great Wall 450SD... It seems that there is a 400sd... And Sopoda's 350sd... You can go online and see ... And many more.

Huntkey's jumper is not bad, the reputation is also good, there are few problems, and the quality is ***.

Not afraid of online shopping, especially JD.com. Jingdong's power supply brands are basically first-line and second-line regular products, and the possibility of problems is very small. Taking a step back, even if something goes wrong, if you are in a second-tier city, JD can pick up the parcel for free, and then help you send it for repair, replacement or return.

If you recommend a power supply, let's talk about the installation shop first. Second-tier cities generally have Hangjia, Cooler Master, Great Wall, Big Buffalo, Antek has some, the front few are considered second-tier brands, the quality is relatively ***, there are these brands to buy with confidence, the specific buy depends on which is cheaper, there is nothing to pick. Of course, if there is an antitek, it is preferred.

Huntkey Jumper 500 Power Supply 289 (the one you see).

ANTEC VP500P rated 500W power supply 269

ANTEC VP 550P V2 is rated at 550W 369

FSP Group AU-500 Power Supply is rated at 500W 499 (expensive, but it's also really good).

TT Veyron 650 Power Supply (Rated 550W 299.)

Jumper is a double-tube forward double magnetic amplification,It was more expensive before.,Recently, it's been engaged in activities.,Don't enter at this time, wait for when?。。。

Power supply? Do you want ***?

So, Antek, Cooler Master, Corsair, choose from these three, they are all ***, not false standard power supply. These three brands, especially those of Corsair, do not need to gamble on character.

A 300W power supply can drive a graphics card up to 150W.

Because there are three main power consumption of a computer, one is the motherboard, and the motherboard generally needs 20-30W of electrical power. One is the CPU, because the brand is different and the model is different, the electrical power required is wider, from 50W to 100W. Another is the graphics card, because the GPU of the graphics card is different, the difference in power consumption is very large, but it can be based on whether it has an auxiliary power socket, the socket uses a few pins, to make a simple judgment, the maximum power supply capacity of the computer PCI-E interface is 75W, if the graphics card does not have an auxiliary power socket, it means that its power will not be greater than 75W, a 6pin graphics card auxiliary power socket, can provide power supply power in 75W, an 8pin graphics card auxiliary power socket, It can provide power supply at 90W.

The power consumption of other hardware of the computer is less than 10W.

Therefore, to determine the 300W power supply, how much power graphics card can be bring, you can simply calculate it, the computer in addition to the graphics card, all according to the maximum power to calculate, the motherboard consumes 30W, CP consumes 100W, a hard disk consumes 8W, two memory modules consume 10W, plus the mouse, keyboard, etc. 10W, a total of 158W, 300W power supply minus 158W, leaving 142W for the graphics card, so to choose the graphics card, you can only bring a 6pin auxiliary power socket graphics card.
