The Corsair RM1000e (2023) has actually really impressed me. I am often not sure what to expect from Corsair power supplies, as over the years they have proven sometimes to be a little ‘hit and miss', especially with their more budget offerings. ‘Hang on!' I hear you shout, ‘surely you aren't saying this 1000W unit is a ‘budget' PSU'?
Currently Amazon have this brand new 2023 RM1000e model listed at £167.95 HERE. Overclockers UK currently have the older 2022 model showing at £144.95 inc VAT – making this a relatively inexpensive high power output supply platform. Other 80 Plus Gold rated 1000W power supplies from companies such as ASUS are often around the £250 mark (HERE).
Technically this test unit proved very capable. Load regulation is solid, and ripple suppression, while not class leading, falls well within the safe side of industry rated parameters. The unit also achieved 80 Plus Gold certification without a problem during our tests. The use of a Taiwanese 105C rated Elite Jinshan primary capacitor seems to indicate a little cost cutting over a Japanese Nippon Chemi Con or Rubycon counterpart, however after speaking with several people in the industry, the reports I am getting back on these caps is positive. The small 14cm profile also means the RM1000e will be able to fit into a massive array of chassis without causing possible routing issues.
At this price and with the test results we achieved, it goes without saying that this power supply comes highly recommended. Many gaming systems will demand between 400 watts and 600 watts of power under load, so this unit will be achieving its highest efficiency (between 40% and 60% load). At these levels, the fan is quiet, the capacitors are running cool, and power delivery is very clean. With the current pricing around £165 it really is a very sensible, price oriented offering from Corsair.
You can pick one up from Amazon UK HERE.
Pros:
- Pricing is super aggressive.
- Quality design.
- Low noise levels with our sample.
- 80 Plus Gold rating achieved.
- Delivered a sustained 1100W of power.
Cons:
- Technically not a ‘class leading' design.
KitGuru says: Corsair are pricing this RM1000e super aggressively. At the £165 asking price, it makes little sense opting for a lower output model to save a little money. Many modern gaming rigs under load demand between 400-600 watts and this 1000 watt unit hits maximum efficiency here.
