Corsair RM650x or HX1000 (FOR GAMING & MAKING VIDEOS)

[pharmit_singh]

Hi, I use my PC almost everyday to play games and make videos so it's always on and I want to know which is the best PSU in terms of perfomance and efficiency. I'm currently using the HX1000 but it's a little big for my new case to fit it and also overkill. I don't know about the technical stuff about psu so I would like an easy to understand answer. Thank you.

my specs:
OS : Windows 7 Ultimate x64
CPU: i7 4790K 4.0GHz
COOLER: Cryorig R1 Universal
SSD: Intel SSD 730 Series
HDD: 2x WD Black 6TB & WD Green 1TB
MB : Asus Maximus Formula VII
GPU: ASUS ROG Matrix GTX 780 Ti 3GD5
RAM: Corsair Vengeance Pro 2x8 DDR3 2400MHz (16gb)
PSU: Corsair HX1000

A reliably built 650W-750W Gold/Platinum/Titanium rated PSU should help you go a long way with lowered electricity bills and longevity.

How much are you looking to spend and where are you located?

Around $120. I'm from Malaysia and I think the RM650x is good enough for my specs and for future updgrade to GTX 1080Ti gpu.

Efficiency-wise the HX1000 should already be very good, seeing as it's 80 Plus Platinum and ETA-A rated. According to the efficiency graphs for that PSU at Cybenetics, it should offer at least 90% efficiency from around 150 to 750 watts, which would cover your system when under heavy load, and at least 85% efficiency from around 60 to 150 watts, which should cover your system when at idle, and for most desktop use.

Moving to another PSU will not likely make any noticeable impact on your electricity bill, so it would probably be better to just keep the PSU that you have. PSUs will only draw the amount of power they need, so if your components are drawing 400 watts from the PSU under load, your PSU shouldn't be consuming more than 440 watts from the wall, and if the components are drawing 100 watts at idle, your PSU shouldn't be drawing more than 115 watts from the wall.

Moving to an equally high-end 650 watt PSU shouldn't change the amount of power being used by much. Looking at the efficiency graphs for the RM650x, the efficiency levels appear to be quite similar for the lower part of that range, but at heavy load levels they are actually slightly worse. Again, that would probably only amount to an increased power draw of maybe 2% or so from the wall when gaming, but it certainly wouldn't be any more efficient than what you already have.

Thank you so much. I really appreciate for your brilliant answer. I will be keeping my HX1000 then! Thanks!
