Lightweight PSU for RTX2070S and i5-10600KF

[SabianSVK]

Hey there, I need help picking right PSU, and I am a little overwhelmed by the PSU Tier list chart ...
 

Purpose = to have VR capable machine ON-THE-GO, as my sister is artist and will move whole setup every now and then. Therefore I would like to choose good and not overpriced PSU, which doesn´t weight as much as elephant. Needs to be packed in as small case as possible, however i could NOT go for ITX, as i need extra PCIe slot for Intel WiGic card (part of HTC VIVE Pro WIRELESS set). PLEASE, use THIS SHOP - Alza.sk ... if it´s not there, theres 90% chance I won´t find it anywhere around... Recommended wattage by PSU calculator was 650W, I was thinking about 750W to give it a little room for light OC and stability

 

SPEC = Intel i5-10600KF, Gigabyte RTX2070 Super WindForce OC 3X 8G , MSI MPG Z490M Gaming Edge WIFI (mATX) + HyperX 2x8GB 3200MHz CL16 Predator
Case = GameMax Silent HILL/H606

THANK YOU LTT  

EDIT //
My budget for whole system is 1500€ at most, I am already maxed there, counted approximately 90-110€ for PSU
Again, she will travel with 3 of those PCs around Europe, so I HAVE TO go with that case, the only case smaller than this was either ITX or cost like 200€ ..

i'm confused, what do you actually mean by lightweight PSU? does it mean it has a small form factor? or? whats your budget?

psu calculators exagerate wattage so you buy more expensive psus. 550w are enough for your build.

a bit difficult to find the weights of these.

i'd recomment this one based on price/quality

PSU calculators already give a lot of headroom. Consider an SFX PSU ~550W if size and weight are important to you.

What's your budget?

 

Also, definitely don't get that motherboard and case.

Lightweight as in weight, kilograms ... They are free to be normal ATX form factor, but some PSUs weight 1.7KG, some weight 3KGs, which is noticable when you have 3 of those in your luggage ..

Okay then, no need for 750W, but I´d rather still keep 600-650W then ... I am one of those guys who don´t like to be tight on things  Thanks for suggestion

What brand are you talking about, please? getting multiple results back...

1400-1500€ .. which I am already maxed on, and plan on buying from multiple stores to save a buck here and there. Amazon, ebay and such (US online shops) doesn´t work for me, sadly ... due to a PURPOSE of build (read in OP), I cannot go for bigger case, nor ITX, this was smallest mATX case I could find ... Also, there is not many other MTBs with Z490, mATX and built-in WIFI ...

"SFX" is a form factor not a brand. It's physically smaller than a standard size (ATX) PSU.

 

You'd have to choose a case with support for SFX PSUs.

10600kf consumes max 185W when overclocked, the 2070 super 215W. the rest of the system doesn't use more than 50W.

SO you get 450W under extreme load (prime 95 + Furmark run at the same time), which is an unlikely situation. 

during normal gaming and usage, it will draw around 350W.

a 550W psu will be enough.

people power 9900k and 2080 ti with 550W psus and are fine.

And, if weight is really your primary concern, a lower wattage means fewer internal components means potentially lower weight.

Oh, yeah .. some PSUs have SFX in a model name as well tho, thus why I was confused  Nope, i cannot go ITX case, thus no reason to go SFX format PSU ...

Oh, okay ... 550W it is then ... needs to be semi/fully modular ... any recommendations?

not sure which ones are lighter. I've already recommended the cheapest one I could find that is decent. I could recommend others more expensive, but there is no guarantee they will be lighter.

I just don´t know how to read PSU Tier list, so any great PSU recommendations will be helpfull. If the weight isn´t specified, I will google for it and compare. But I really don´t know which brands and/or model line-ups to avoid ... Thanks

I'll give you a list of very good psus, I would recommend any of them. It's up to you then to search for their weight.

Thanks @boggy77, so i checked them out and this is what I found out ... of course, it does not have to be correct and exact info, but it´s what we´ve got

	lbs	kg
GIGABYTE G750H	4.90	2.22
Seasonic Focus GX 550W Gold	3.31	1.50
COUGAR GX-F550		2.10
Seasonic Focus 650 Gold Semi-Modular		1.63
SilentiumPC Supremo FM2 Gold 650W		2.33
Corsair RM650x (2018)	3.36	1.52

I´ll probably go for either Seasonic then ... any thoughts between these 2?

i'd recommend the corsair rmx and the seasonic GX. slight preference to the corsair

I don't know how important this is to you, just thought I'll mention it. The semi-modular Seasonic has a slightly lower warranty period (7 years) than the Focus GX (10 years)

 

Corsair IIRC offers also 10 years for the RMx
