    Default DEEPCOOL DQ 850-M-V2L & CWT GPX




    http://cooln.kr/bbs/review/797612?p=3

    Brand new platform from CWT - GPX?
    Looks like it's a successor of GPU.

    I noticed GPX and Deepcool plenty of time ago, but there was nothing to talk about since the Deepcool units weren't out yet. :'( Finally they're here, thanks for sharing

    They've raised idle RPM

    They might be using a cheaper motor in the fan that doesn't support a lower RPM (or doesn't support it without considerable motor noise).

    FYI: GPX is cost down GPU. Lower hold up time, higher ripple/noise, regulation not as tight. But much lower cost.

    Are you sure you're not talking about some different platform though? In this test it achieved 16mV ripple (same as GPU-based Whisper M 850W on TechpowerUP), and 0.4% regulation (tighter than 1.07% of GPU), although their testing isn't as detailed as Aris'.

    I don't see "much lower cost" either, considering GPX is full bridge rather than GPU's half-bridge and uses the same NCC caps everywhere. On the other hand the review didn't look closely at any MOSFETs to check their quality, and the transfomer is traditional-style (at least with the taps closer to output rectifiers). So far I can only see improvements and no cost downs, but that's just what I can see from this limited review.

    Perhaps you actually meant CWT GPR? As in, to say that GPR is cost-down of GPU?

    Perhaps it's not actually GPX.

    I got the break down directly from CWT. GPX is a cost down GPU.

    Maybe you can recheck it or show picture to us(which I hope ).

    Yes! It is CWT GPU platform which is quite solid, but I would suggest you to avoid this brand who has no reputation in PSU field and get Corsair RM (2019) series with better performance...

    Hmm, where to start ...
    - OP doesn't buy this PSU or asking if they should, they're just sharing this review for a PSU on new platform with us
    - Which is (new platform) isn't CWT GPU but GPX, it's literally in the post
    - Deepcool has quite a bit of experience in PSUs field, not all of their PSUs are good but Deepcool DQ-M on 'old' CWT GPU certainly is. Too early to say anything about this one, so far it indeed seems like a somewhat costdown version of CWT GPU.
