今天,我們將從各種海盜船電源供應器(Power Supply Unit,PSU)中,找到最適用於NVIDIA GeForce RTX 4090的選擇。考慮到現代顯示卡(GPU)的巨大電力需求和高價位,我們極為推薦高品質且高效率的電源供應器。
在深入討論之前,您應該知道您的系統需要達到一些最低限度的要求:
RTX 4090系統需求
所以,我們將從不同型號的RTX 4090的電力需求開始,先介紹挑選RTX 4090電源供應器需要考量的事項。
值得注意的是,並非所有 RTX 4090 顯示卡規格都一樣,重要的是它們的電力需求不同。它們的耗電量會根據特定型號而有所差異,因此您必須知道您的RTX 4090 耗電量,據此來選擇適合的電源供應器。此外,短暫的電力峰值是常有的情況,最好選擇規格較高的電源供應器。
爲此,表格列出了一些 RTX 409s 顯示卡及其TDP(Thermal Design Power,熱設計功耗),以及建議的最低電源供應器瓦數。
您應該注意列表并不完整,如果您的顯示卡不在列表中,請務必自行檢查。您可以在使用手冊或製造商網站上找到電源供應器的瓦數建議及TDP資訊。
Model | TDP (Thermal Design Power) | Minimum recommended PSU |
---|---|---|
NVIDIA GeForce RTX 4090 (Founder's Edition) | 450W | 850W |
Zotac NVIDIA GeForce RTX 4090 24GB Trinity OC | 450W | 1000W |
ASUS NVIDIA GeForce RTX 4090 24GB TUF Gaming | 450W | 850W |
MSI NVIDIA GeForce RTX 4090 24GB SUPRIM X | 320W | 850W |
Gigabyte AORUS NVIDIA GeForce RTX 4090 24GB MASTER | 450W | 1000W |
ASUS NVIDIA GeForce RTX 4090 24GB ROG Strix OC | 450W | 1000W |
MSI NVIDIA GeForce RTX 4090 24GB VENTUS 3X 24G OC | 450W | 850W |
Gigabyte NVIDIA GeForce RTX 4090 24GB GAMING OC | 450W | 1000W |
從這個列表中,您可以看到建議的電源供應器和TDP不盡相同,有些只建議320W TDP和850W電源供應器。儘管如此,我們今天還是著重1000W電源供應器,因為它能提供較多應對瞬間峰值的空間,在升級電源供應器之前也可為系統添加更多的零組件。我們也會納入850W的選項,提供給那些不需任何額外瓦數的使用者。
您最佳的全模組化選擇是海盜船RM1000x SHIFT,它不但完全模組化,且連接線也是接在側邊而非尾端,讓布線更簡單、更整齊。它還具有Zero-RPM風扇模式,除非必要,否則風扇不會旋轉,可讓系統在低功耗時更為安靜。如果您的系統規模特別龐大,它也有1200W規格可以選擇。
我們提供海盜船RM1000X SHIFT的規格給有技術專長的使用者,包含功率表和連接線配置。我們也在本頁面上提供了其他電源供應器的規格表。

雖然RTX 4090的體積很大,但只要您使用的機殼有足夠空間,仍然可以將其裝進小型機殼裡。事實上,我們的2000D AIRFLOW SFF機殼可以裝得下多種型號的RTX 4090(只要該RTX 4090長度不超過365公釐),這代表我們於此必須納入SFX電源供應器,並且我們已選擇的是海盜船SF1000L。

對許多電腦發燒友來說,讓系統保持安靜運作是最重要的,如果您想在有負載的情況下也能達到近乎無聲的運作,海盜船HX1000i是最佳選擇。和RM1000x SHIFT及SF1000L一樣,它具有Zero-RPM風扇模式,在低負載下可以真正無聲運作。但與其他電源供應器不同的是,它採用磁浮風扇。這代表風扇和軸承幾乎無接觸,因此可達到接近零摩擦。更少的摩擦=更高轉速和更低噪音。

並非每個人都需要額外的電力容量來進行未來升級,這很合理,因為這樣做可以降低成本,此外,功率較低的電源供應器通常尺寸也比較小,可以為儲存裝置騰出更多的空間,因為在很多時候,這些機殼的安裝位置都靠近電源供應器。更小尺寸的電源供應器也可以讓布線更簡單,如果這對您來很不錯,我們推薦海盜船RM850e全模組化電源供應器。

So, those are our picks for the best PSU for the RTX 4090. However, now we're going to take a moment to answer some of the more common queries surrounding this GPU, our PSUs, and more.
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.
What power cable does the RTX 4090 use?
Typically, RTX 4090 GPUs come with an adapter cable that takes three or four 8-pin connectors and combined them to the 12VHPWR 16-pin socket on the GPU itself. However, this is only necessary if you're using a PSU that isn't ATX 3.0 certified. All the PSUs we've recommended here have that certification, and thus include the 12VHPWR cable in the box, so you won't need to use the adapter that came with the GPU.
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 ofvalidating 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.
