XPG Core Reactor 750 W

crmaris · Jun 9, 2020

The XPG Core Reactor 750 W is compact at only 140 mm deep, achieves high performance in all areas, and is whisper quiet under normal operating conditions. XPG has a strong first entry for the PSU market in the XPG Core Reactor—we are anxious to see more from this brand.

Great review. XPG can make some great stuff.

Just one thing... A single EPS can handle a 3950x. You'd need twin EPS for a 10900K and should have it installed for the 10700K.

Thank you for pointing this out. I am mostly referring to Threadrippers, where a pair of EPS connectors is a necessity. Unfortunately, I don't have real Wattage consumption on the 3950x, but I strongly believe it will stress a single EPS, especially at boost frequencies.

A single 8 pin can push 384w in basic form.

An you need subzero cooling to get a 3950x over 300w AFAIK.

Zen 2 is very limited by current.

384W the connector on the PSU's side will melt. Basically it is 336W, 7A per +12V wire, and EPS has four of them. Still, the Molex connector on both the PSU and load side cannot handle so much for long.

BTW I have seen with my own eyes a 9900k drawing close to 300W at boost clocks. It is way better to balance the load between two connectors, to have lower voltage drops so the mainboard's VRMs are pushed less (and emit less heat).

I thought the 8 pin EPS with formed connectors was good for 384w, I was wrong. Though if the wires running up to it are only 18ga instead of 16ga it would be a lot less capable.

I guess the 384w for an 8 pin is based off 8a per pair and solid pins on the plug side. 336w is the formed pins that were originally used.

Oh I don't disagree the 9900k definitely goes over 300W and the 10900K can pull 370W on a decent 360 AIO.

That would definitely put you in the 8+4 minimum category for a 8c/16t or higher Intel. Definitely explains why for AMD on boards with any notion of extreme overclocking they have 8+4. A 3950x on water reaches into the range of 270w.

The more we learn. Right?

Nice looking unit thanks for the very detailed review.

It looks like this price is the new normal for high endurance, low ripple PSUs. Finding any in stock right now is the problem.

I thing you have misconception about Ryzen power draw. At stock a 3950X cant go over 142W.

The AMD Ryzen 9 3950X Review: 16 Cores on 7nm with PCIe 4.0

On overclock it could reach 270W but who you do that to lower single core performence. Or the 270W is number is maybe for the whole board.

Now this is the kind of stuff I like to see. A non Teir 1 company putting out what looks like a decent product. As for the price? Well The pricing of late on many computer components are getting to the stupid level. Just about everything is going up So the price on this PSU is on par now with my Rosewell 850 Watt Capstone.

crmaris · Jun 10, 2020

The prices lately in all IT products are sky-high. Hope they come back to normal levels, soon.

Nippon Chemi-Con + Nichicon caps. Not bad. Looks like decent CWT platform overall
