NVIDIA GeForce RTX 4080是一款高性能显示适配器,它需要足够的电源来呈现当今游戏极为精细的画面。要实现这种精细度的技术需要足够的电源供应,当然,电源也必须有足够的容量满足PC中所有其他零组件的需求。在讨论这些议题之前,有一些项目可确保您符合最低配置的要求。
RTX 4080系统需求
当然,当我们提到RTX 4080时,其实是指从NVIDIA研发的相同标准所衍生出来的不同产品,这代表您购买的特定RTX 4080显示适配器可能其他型号之间有很大的差异,因此,以下有一些最受欢迎RTX 4080型号的非完整列表,显示其TDP(Thermal Design Power,热设计功耗)和所建议的最低电源(制造商建议)。
*不同型号之间的电源需求可能有所不同,建议遵循您特定显示适配器型号的要求。
型号 | TDP(热设计功耗) | 建议的最低电源瓦数 |
NVIDIA GeForce RTX 4080(创始版) | 320W | 750W |
微星NVIDIA GeForce RTX™ 4080 16GB SUPRIM X | 320W | 750W |
华硕NVIDIA GeForce RTX 4080 ProArt OC 16GB | 320W | 750W |
华硕TUF Gaming GeForce RTX 4080 16GB | 320W | 750W |
华硕GeForce RTX™ 4080 16GB Noctua OC版 | 320W | 750W |
有趣的是, RTX 4080的TDP和建议的电源似乎不像我们为RTX 4090找到的最佳电源那样多样。我们不确定为什么会这样,但这确实会让玩家更容易找到RTX 4080最佳电源。然而,正如我们所说,这不是一个完整的列表,所以最好还是检查一下您特定型号的4080,以防万一。
对于4000D或5000D这种传统尺寸的机箱,建议使用至少750W的模块化电源,例如RM750x SHIFT,可以提供RTX 4080适当电力,然而,正如我们在小型机箱组装建议中提过,如果显示适配器搭配的是Ryzen 9或Intel Core i9之类的高阶处理器,则建议选择850W、1000W或更大的电源,如果另要配有多个RGB风扇及其他零组件,可能也要将这些因素纳入考虑。
是的,您可以放心,750W功率的电源对RTX 4080来说就已足够,但是为以防万一,最好多了解一些讯息。因此我们在此提供海盗船RM750x SHIFT的功率表和连接线配置。

对于喜欢海盗船2000D等小型机箱的使用者而言,我们当然也推荐SF850L,是的,对RTX 4080的需求来说,它的功率有点过大,但电源过剩总比不足好。
值得注意的是SF850L不像RMx SHIFT电源有侧面连接器,不过,侧面连接器并没有那么重要,反正小型机箱也无法使用这类连接器。让我们看看这款电源的规格。

有些组装PC的人和游戏玩家不关心噪音问题,但对另外一些使用者来说,则需要PC尽可能安静。因此,我们决定在此列出我们自家的超低噪音电源海盗船RM750e。
顺道一提,它保持如此低噪音的方法是使用120毫米来福轴承风扇并搭配特别计算的风扇曲线。此外,它还具有Zero-RPM模式,所以当您不执行任何高强度工作时,风扇会完全关闭,使得电源完全安静。

Ok, we've located our 3 best PSUs for the RTX 4080, but we thought we'd throw a few FAQs we see a lot at the bottom and answer them for you.
How long is the warranty on a CORSAIR PSU?
All our PSUs come with a minimum of a 3-year warranty, with many holding 10-year warranties. You can find the warranty for each specific PSU on our support site.
Are there still issues with the 12VHPWR connector?
Following the release of the 12VHPWR standard, there were some incidences of the connector melting, due to it not being fully-seated when connected. This is avoidable, just make sure the cable is fully connected at both ends, and avoid bending the connector during the cable management process. Our PCIe 5.0 12VHPWR GPU Power Bridge can help with that, allowing for neater cable management, and a lower likelihood of the cable being bent too much. (Just check it will work with your specific RTX 4090.)
What does the "80 Plus" symbol mean?
This is an industry-standard way of validating the efficiency of a power supply. All our PSUs, including those on this list, carry a certification of Gold or higher.
Are all PSU cables compatible with all PSUs?
No. there are different standards and connector types at play here. This means you have to be very careful. Check out our compatibility matrix to make sure. Plugging the wrong type of cable into your PSU, or any other component in your system can have disastrous consequences.
