The transient response is good on all rails, especially at 12V.
Transient Response ATX v3.0 Tests
The PSU passes all ATX v3.0 transient response tests.
The 12V rail’s performance is good!

How can I make the EPS cable problem safe? Can I only use one of the connectors? Can I order a single cable from Thermaltake?
I’m wondering if this is the same unit as “PS-TPD-850FNFAPE-3”, as sold by Scan UK here: https://www.scan.co.uk/products/750w-thermaltake-toughpower-pf3-native-pcie-5-fully-modular-80plus-platinum-single-rail-708a-120mm-f
It’s only £130 in the UK at the moment and seems like a good deal. Thanks – Nick
Yes, it looks to be the same unit.
How serious “problem” is the single cable for the 2 eps connectors? Do you think that the combination of a 7700x (or 7950x) and an asrock x670e steel legend would set this on fire? (No overcloking, only standard operation voltages. If it is an actual problem, then the next candidate is the rmx850 shift, are they equal? they seem so)
In a single 12V rail it actually is. When both connectors can deliver more than 450W and take from a single PSU socket, all hell can break lose if something goes wrong.
hm, I see
I’m also building a 7700X system and want this PSU. I’m sure only one 8-pin EPS connector is needed to power the 7700X, so Vman & I shouldn’t need to worry, right?
I should have said in my previous comment, that I base my opinion on this: “Both the 7700X and 7600X use less than half the wattage a single eps can provide” from https://www.techpowerup.com/forums/threads/ryzen-zen4-are-both-cpu-power-plugs-required-now.299330/
Hello, I am now faced with choosing a power supply. I’ve been looking at your tests for a long time because I’m interested in it, but I want to choose a certain unit for my computer. Previously, I had a Bitfenix Whisper M 750W, but unfortunately its fan failed and I had to send the power supply back under warranty and received a refund.
I’m aiming for 750w/850w,
I care about low ripple, Japanese capacitors, quiet fan operation and two wires on a single pcie cable to the GPU (I have rtx 2070).
I don’t know whether to go with old units or ATX 3.0.
My unit under full load (prime95 + furmark) consumes 400W from the socket.
I have a maximum of EUR 140 to spend, I live in the EU.
Can you recommend something to me?
I would say go for an ATX v3.x unit to be future proof. Take a look at my best ATX v3.x PSUs in the 750W category, which ones fells into your budget.
Thanks for the answer. You’re doing an amazing job. I think I’ll go with the RM750x/850x shift.
Will there be a review of XPG Core Reactor II? I see it in the table, but there is no separate article.
I’m still considering Deepcool PX850G and XPG Core Reactor II 850W. They are available in my country at an affordable price. Which one will be the best idea?
Hi Benek, you bought the XPG Core Reactor II 850W? I’m considering buy it and I want opinions!
